To be useful, test must meet certain specifications. Studies of reliability tell us whether test scores are consistent over time. Studies of validity tell us how well a test measures what it is intended to measure - how well it predicts according to an acceptable criterion. Uniform testing procedures are necessary for a test to be reliable and valid.

Good morning, today I`m going to speak about ‘Mass media’. To start with, the mass media play an important part in our lives. Newspapers, radio and especially TV inform us of what is going on in this world and give us wonderful possibilities for education and entertainment. They also influence the way we see the world and shape our views. Of course, not all newspapers and TV programmes report the events objectively but serious journalists and TV reporters try to be fair and provide us with reliable information. It is true that the world today is full of dramatic events and most news seems to be bad news. But people aren't interested in ordinary events. That is why there are so many programmes and articles about natural disasters, plane crashes, wars, murders and robberies. Good news doesn't usually make headlines. Bad news does. To my mind say that journalists are given too much freedom. They often intrude on people's private lives. They follow celebrities and print sensational stories about them which are untrue or half-true. They take photos of them in their most intimate moments. The question is — should this be allowed? The main source of news for millions of people is television. People like TV news because they can see everything with their own eyes. And that's an important advantage. Seeing, as we know, is believing. Besides, it's much more difficult for politicians to lie in front of the cameras than on the pages of newspapers. As far as can see, many people prefer the radio. It's good to listen to in the car, or in the open air, or when you do something about the house. In addition, other scours of information are newspapers. The best known are `Lietuvos rytas` and citizens  of Kaunas read `Kauno diena`. These concern themselves, as far as possible, with factual reports of major national and international news stories, with the world of politics and business and with the arts and sport. Newspapers don't react to events as quickly as TV, but they usually provide us with extra detail, comment and background information. The Internet has recently become another important source of information. It is believed that in the year of 2010 there will be at least 500 million people on the system enjoying virtual reality. It means that more and more people use Internet for searching the news instead of reading newspapers or watching news on Tv. Its main advantage is that news appears on the screen as soon as things happen in real life and you don't have to wait for news time on TV. Thanks to Internet now news are easy of access. To sum up, mass media reach very large numbers of people. For this reason it plays a significant role in our lives. More than even before, mass media offers us a window to the world and it depends only on you which scours of information to choose.

Eventually, genetic engineering will allow us to create the perfect human. It will be hard to get used to. Parents will order a baby who will grow up to do a slam dunk or to have a Barbie doll appearance. But after the 2082 winter Olympics, some babies will be created aerodynamic, so they can sail like ski jumpers. Soon, powerful little motors will be added so they can fly, and a new fad will really take off. Billions of slam dunkers will jump for joy, while billions of Barbie dollers will become totally depressed. Also, genetic engineering will allow us to mix plants and animals. So, should we allow a female researcher to cross a man with a tree? She would then have something much more stable and dependable, and he wouldn't run around as much. But who would want to be a tree? If that was allowed, then what would the male researchers come up with?

Golden Rose str. 15, P.O. Box 2312, London Dear Carla, Thanks a lot for your letter and sorry for not writing before – I was soooooo busy! You know, school, music, friends and so on.:) So, you decided to come to my country – it’s so great! I can’t wait for you to come! You said that you have no ideas what places to visit and where to go. Well, I have some. First, I recommend you to stay in capital – Vilnius – or in Kaunas. It is the second largest city in Lithuania and it’s where I live. :P Next – if you want to make an acquaintance with our culture you’d better stay in Vilnius. There you can visit lot great places. For example – Gediminas Castle, or a Television Tower with a valiant (and expensive, of course) cafe “The Milky Way”, from where you can see a view of town. Also the Royal Palace of Lithuania and amazing St. Ona church which is inflexible fascinating. And because of that Napoleon wanted to take it on him palm to France! If you’ll decide to stay in Kaunas, you should visit Liberty Avenue which is a symbol of town. But because of that, that in it is now very much shoe shops it’s sometimes called “Shoes Avenue”. We also have Kaunas Castle, a lot of museums, Nemunas and Neris confluence, which is very beautiful place, and ctr. So, I promise – you won’t be bored. Can’t wait for you to come, Love, Emily

Dear Vic, Hi- how are you? Thank you for your letter. Actually, that’s what I’m writing to tell about “Teacher’s Day” in may school. We have “Teacher’s Day” on October 5 th on this day the twelfth form student’s teach schoolchildren. I and may fiends were biology teacher’s. We played with schoolchildren, it was very funny. “ Teacher’s Day” is a celebration for teacher’s, when schoolchildren greet them. Most often schoolchildren present flowers. This day in important in my life, because I can teach schoolchildren. I hope you would like this day in my school. I hope you are OK and will write to me soon. Love, Vaida

I am writing to you to complain about the tent which I bought through your mail order catalogue last week. I am very disappointed with what I received, as it is nothing like the one I saw in your advertisement. Firstly you led me to believe that it fits to 6 people, but truly it fits barely for 4. I strongly wanted the one for 6 people. In your advertisement you stated that there will be torch and batteries with every tent, but I didn’t fond these things. I was really disappointed about that. Moreover you have written that there is durable canvas, but in fact the tent was slightly torn and the zip got stuck. I didn’t expect that the product was so in low keep. Definitely misleading was available colors. O wanted red one, but unfortunately got pink. In addition I want that you can demand an immediate replacement or I need a full refund.

He knows more and more words, and he often says two words: “what`s that”, and ”why”. A child wants to know more about things around him, so these two words are the way to the knowledge. One language cannot give so much news, as few languages. More languages – more keys to open the door to the world. It`s not one door to the world, and language can open not one door. We can go to the world reading books. In this field language is very important. Not all books are adapted to the mother tongue. The news from the horse`s mouth are much better. Some people say, that a book is an old – fashioned thing, but we cannot forget this door to the world. Other way to the world is TV. Nobody can say, that it`s old – fashioned thing. Technologies develop faster and faster and our task is don`t fall to them. We can watch a lot of foreign programs, but it`s not necessary if we cannot understand foreign languages.

What is more, it is a very big family. There are five children and they all are very nice. So I work here as a nanny. Sometimes I tidy rooms, because children always make a mess. Their mother and father are sweet to me too. They do not give me too much work. In their free time, I go with them to the cinema or theatre. I am having a very good time here.

I want to tell about my ideal holidays. I am going to write about summer holidays in Palanga. One day I and my friends decided that enough to sit at home and need to do something interesting. So we decided to go to Palanga. Our group was composed from four people: I, my boyfriend, his brother and cousin. We packed lagguages, sat to the car and after five hours we were in Palanga. . We rented a flat, brought all the things inside and went to the beach. The beach was crowded. We lied on the warm sand and started to sunbathe. Sun was very warm and it was so good! Sea was very quied and we decided to go to swim. The water was cold but we swam, played and splashed as if it was warm. In the evening we came back from the beach, and then we all had a shower and went to the town. Our stomaches were growling with hunger. We went into the cafe to have a dinner. When we got full we went for a walk into Basanavičius alley. There was a lot of funfairs. We went to the horror room, after that to the big wheel, witch turned as very fast. It was so exciting! After this dispots we went to the club. There our group drank some cocktails and went to dance. Some hours later we all went back to the flat and quickly fall to sleep. Next day we woke up and saw that the rain was getting to start. So we decided to stay into flat and to think what to do in the evening. But in the evening was raining too so we just went to the seaside to see the sunrise. We didn’t bored. In the flat we played with cards and witch from as had lose that had to do a work. It was funny. Some successive days our group spent all time in the beach or in the dene, in the evening – in town’s clubs. Together we danced, wollowed, met a lot of friendly, accommodating maybe and some strange people. We were in Palanga all week. Every day brought me something new and interesting. Last day my boyfriend met his cousins so half day we communicated with them, about nightfall we packed and leaved the town. Ridding home my boyfriend’s brother and cosin slept, I and my boyfriend was talked about all time, witch we spent in resort. We were happy that deviced this journey. That week we four forgot homes, funny spent all time and didn’t think that summer is going to past. When we came home was very late. This summer we want to go to the seaside too. I hope we will have the same much fun and pleasure.

Drugs, alcohol and tobacco using circulate between pupils in Lithuania. The most common and the most observable pupils harmful habit is smoking. In Lithuania about 55% of pupils’ smokes in 5- 8 form. Moreover, from 38% until 77% smokes in the higher classes. On the average boys began to smoke in 6- 7 class, or girls in 8- 9 class. Tobacco smoke from a cigarette contains more than 5000 chemicals. Sixty of them are known to cause cancer. Nicotine is a highly addictive drug that acts as a stimulant, causing your heart rate and blood pressure to rice. As you smoke, tar coats your lungs and increases your risk of lung cancer. Smoking causes about nine out of ten cases of lung cancer. In addition, it causes approximately one- third of all heart disease and strokes. Drugs are the other harmful habit. Drugs is mostly using in discotheques, parties, nightclubs, recreational centers. About 2- 3% of pupils have tried or sporadically is using it. Pupils use drugs to relax or sedate the central nervous system. They can cause cyanosis. In addition, they can paralyze the portion of the brain that controls breathing, and thus cause death. Using of alcohol is very common: about 92- 95% pupils are taste it and about 10- 21% use it regularly. Alcohol is a drug, a chemical that changes the way the body works because of the chemical reactions in the brain, and its affects the way people think, feel speak and move. Alcohol is the number one drug abuse problem today. It is a direct cause of liver disease, stomach ulcers, pancreatitis, brain damage and other physical illnesses. K To sum up, these habits is very harmful fore everyone and especially for pupils. Therefore, if we want to prevent it firstly we should begin from ourselves and take attention what is happening around us.

It is estimated that humans have between 50,000 to 100,000 different genes; some of them are linked to particular diseases and conditions. Scientists have now identified nearly 4000 conditions that are limited to single defects in a person’s genetic code. Researchers all around the world are currently engaged in “The human genome project”, which aims to identify and define the function of every gene to be found in the human body. Through this they hope to locate errant genes, thereby getting a better understanding of every disease that is genetically transmittable and if possible find a cure for it. Genetic engineering, where by the defective gene sequence is cut and remodeled, is one route scientists might take. At present genetics can be a reliable predictor of who is likely to develop a particular fatal illness. Many feel that this information has the potential to cause as much harm as good, among the 10 percent of the population who may be affected. Some say that people would not be able to cope with the knowledge that they were likely to contract a terminal illness, but genetics argue that everyone has the right to know so that they could plan the rest of their lives. Some women who have been told that they are likely to develop breast cancer have chosen a surgery to remove the breast in order to increase their chances of survival. Genetic engineering is big business, and many experiments take place on animals. Fruit flies have been produced that they have extra eyes on their wings and legs; two years ago scientists grew an ear in a test tube and then transplanted on a laboratory mouse without immune system in order to see if it would be rejected. Harvard University has even patented its own mouse known as “nocuous” which has been genetically manipulated to develop cancer. Imutran, a Cambridge-based biotechnology firm, have produced a pig that is transgenic, from which they hope to be able to supply donor organs such as hearts that are in short supply for transplantation. The revelation that scientists at Cambridge University have successfully transplanted the hearts from genetically altered pigs into monkeys is the most wonderful news to have emerged from the world of medicine fro more than a decade. We are all to familiar with the bad side of science – here is a cause for being happy. The implications are stunning. We are witnessing the forward in human happiness. The chance now exists that hundreds of thousands of people, who are waiting for heart, liver and kidney transplants and would die because of the lack of donors, will now live. Suffers from many other diseases will also face hope. Not only will all those who need these major organ transplants be treated but whole new therapies will emerge. Many cancers, for example are now treated by chemotherapy or radiotherapy but in future it might be safer and more effective to just transplant the affected organ. Possibilities are nearly endless and truly amazing. Whole new era of health and longevity is now downing. Names of diseases: Appendicitis, bronchitis, cancer, chicken-pox, constipation – vidurių užkietėjimas, diabetes, diarrhoea – viduriavimas, hay fever – šienligė, hepatitis, indigestion – skrandžio skausmai, flu, insomnia – nemiga, leukaemia, measles – tymai, mumps – kiaulytė, tonsillitis – angina. Shortened one: Genetic engineering A general term for the direncted manipulation of genes, and usually used synonymously with genetic manipulation or genetic modification. A wide range of technologies are involved in this, but most involve the recombinant DNA techniques. Genetic engineering falls into several different categories depending on what is being engineered. Bacteria, yeast. This is ‘traditional’ genetic engineering (over 10 years old). Using recombinant DNA techniques genes are put into microorganisms to make them produce something we want, be it insulin, better beer or protein for food. Animals. Genetically engineered animals are usually called transgenetic animals. They are produced by a combination of fertilization techniques and DNA technology and produce animals that pass on their genetic modification to their offspring. Plants. Sometimes called transgenetic plants. They are created through the use of plant cloning technologies, which involve growing plants from isolated plant cells. Humans. Although the genetic engineering methods applicable to cows or mice are, in theory, applicable to humans, they have not been yet applied for obvious ethical reasons. Some experiments treating disease have been performed: these do not modify the germ cells. This is called gene theraphy rather than more public allarming term genetic engineering.

Dear Sir/Madam I am writing to complain about your restaurant, which I visited on May 6th. Firstly the one of main problem was that food which I ordered was badly cooked, because steak was tough and chips were greasy. What is more your restaurant waiter which took my orders was very rude, and he even did not apologize me for spilling coffee on my jeans. I trust that you will give the matter serious consideration and that this will not be repeated. I am looking forward to hearing from you as soon as possible. Yours sincerely, Arnoldas Mauragas

Regulations for checking and preventing fires were developed. In the reindustrialize era most cities had watchmen who sounded an alarm at signs of fire. Fire fighting tool was simple water. Another important fire-fighting tool was the axe, used to remove the fuel and prevent the spread of fire as well as to make openings that would allow heat and smoke to escape a burning building. Following the Great Fire of London in 1666, fire brigades were formed by insurance companies. The government was not involved until 1865, when these brigades became London's Metropolitan Fire Brigade. The first modern standards for the operation of a fire department were not established until 1830, in Edinburgh, Scotland. These standards set out, for the first time, what was expected of a good fire department. In all industrial countries fire fighters undergo training, beginning with probationary fire fighters' school and continuing throughout a fire fighter's career. Great Britain has several fire training centers. In Russia, fire schools are in Moscow and St Petersburg; Sweden and Denmark have similar schools. Most fire fighting consists of applying water to the burning material to cool it. Fires involving flammable liquids, certain chemicals, and combustible metals often require special extinguishing agents and techniques. With some fuels the use of water may actually be dangerous. Now fire fighters use special technique. Their uniform is made from special material that protects from heat and poisonous gas they have masks and if there is people in the burning house they have oxygen masks for them. This work is very important because fire can make a lot of damage.

Approximately ten years ago there was a day when I had nothing to do and fortunately I found a cooking book. It was old German cooking manual with the nice pictures. Although I could not read German but the pictures were very informative. After few hours my kitchen looked as a ruin and all food-stuff was damaged. In spite of this I have become an enthusiastic cooking fan. Since then my cooking knowledge and experience has improved a lot. Now I specialize in cold meal especially in salad and sandwiches. In fact to make cold snacks you do not need much time and preparation. My favorite salad is made from walnuts and rise. On weekends or holidays I make dinner for my girlfriend or family. Trout in lemon and white vine sauce I cook the best. Several years ago I have begun to use vines as an ingredient of my dishes. Therefore I analyzed many sorts of it. Furthermore vines are very good addition to meal. I drink white vines while I am eating fish and in my minds eye the best choice is Merceau bur it is expensive and rare. More often I drink Chateau du Paper. With meet I prefer red vines such as Pomerol, red Burgundy and red Bordo. Cooking is good and interesting hobby. No doubt it is beneficial to know how to make food because you never know what kind of woman you would get.

. Shaped by the geography of the land and its spatial isolation, the uniqueness and sheer diversity of this nation-continent-island does not go unnoticed by its denizens or visitors. Where else are you presented a choice among wine tasting, getting dangerously close to a saltwater crocodile, fashioning yourself a didge, snorkeling in vast expanses of ancient coral reef, and dancing the night away in the largest club in the Southern Hemisphere? What other continent offers the bustling metropolis of Sydney on the same platter as the vastness of the Outback, the rainforests of Cape York, and the sands of Fraser Island? It is by no means a stretch to say that Australia is a place like no other, and any Aussie (or wide-eyed tourist for that matter) will tell you they'd have it no other way.

. In high school, you couldn’t do that much as a freshman. You really didn’t know what to expect coming from middle school, just that it was a new place to learn. Following the rules was a necessity. If you didn’t get in good with a couple of teachers, the rest of your high school years could be treacherous. Although, if you could get through your freshman year, the other three are a breeze. During your sophomore through senior year, you had made friends with most teachers and could get by with almost anything. If you were in any class with that certain teacher, she would probably let you do favors for her to get you out of class. She would also let you go do things you needed to do, always giving you a good grade, and you didn’t even have to show up to class most of the time. I thought high school was the easiest part of my school days. College is a totally different atmosphere. You still have the same freedom you had in high school, but you don’t have to go to class if you don’t want to. The disadvantage is, you can’t make up any work you missed either. In high school, if you missed three or four days you got the same amount of time to make it up. Here at Maple Woods, there are very few sports you can get into. I think the only sports they have are baseball and softball. In high school, you can get into any sport you can think of. Another thing is that you don’t have to be on time, or stay the whole time. You can get up and leave at anytime you want. The reason for that is, you are paying for your credits, if you don’t pass you don’t get the credit. That is a waste of money, and no one likes to waste money. I prefer college, because you get to make your schedule. You can come in as early as eight in the morning, and leave as late as eight at night. It makes it much more convenient for those who work forty or more hours a week. Even though I prefer college now, I still think high school was the best years of your life.

This situation in Lithuania is getting hopeless. A lot of dangerous criminals are allowed to escape and roam free. There are more and more burglars, kidnappers, murderers and killers who commit crimes and succeed in escaping penalties by engaging good lawyers. Somebody says that police do nothing. But I think its not true, police do what is possible. Just not everything is in their hands. Sometimes and people should help to police officers. For example, often people don’t even call the police as they don’t believe in justice. They think that there will be no punishment for thieves. If they believed in justice and helped police, police would help them better. Touching some other bases, I am able to mention that the most common crimes in my native town are burglaries and vandalisms. Usually, burglars steal from flats and cars small but expensive things. Talking about vandalism, vandals usually are youngsters. They broke small trees, windows and streets’ lamps. Of course, there are and some other kind of crimes as the following: beating, swindle and so on. I live in small town. It means that there aren’t very much crimes or they are quite small. I should admit that now I feel safe, but I am sure that after few years criminals will reign everywhere. As a rule, as city is bigger, as there are more crimes in this city. No doubt, that biggest Lithuania’s cities are full of criminals. Unfortunately, sometimes and small cities are more dangerous than the biggest ones. As far as Panevezys it is said that it is the capital of criminals. I certainly don’t believe that crime control is entirely the responsibility of the police force. I am convinced that prevention is the key to success and that all of us must work together to prevent crime. Not giving criminals the opportunity is the first step.

Reasons for automation 1.high cost of labour in industrialized (and not only) societies skilled labor cost have been constantly increasing. 2.increased productivity Higher production output per hour of labour input is possible with automation than with manual operations. 3.competition The ultimate goal of a company is to increase profits. However, there are other measures that are harder to measure. Automation may result in lower prices, superior products, better labour relations, and a better company image. 5.safety Automation allows the employee to assume a supervisory role instead of being directly involved in the manufacturing task. For example, die-casting is hot and dangerous and the work pieces are often very heavy. Welding, spray painting and other operations can be a health hazard. Machines can also do these jobs more precisely and achieve better quality products. 6.reducing manufacturing lead time Automation allows the manufacturer to respond quickly to the consumer needs. Second, flexible automation also allows companies to handle frequent design modifications. Automation is also allowing organizations to move from the traditional “mass production model” to mass customisation. The traditional model of mass production involves hierarchical control. Workers repeat defined repetitious tasks under close supervision. Such a mass production model is best applied to low-cost, standardized products. Mass customisation is a model for low-cost, high-quality, customized products. It requires flexibility and quick responsiveness. People, resources ant technology are continuously reconfigured to give the customer exactly what he/she wants. The control is decentralized and managers coordinate independent, capable individuals. 7.lower costs In addition to cutting labour costs, automation may decrease the scrap rate and thus reduce the cost of raw materials. It also enables just in time manufacturing which in turn allows the manufacturer to reduce the in-process inventory. It is possible to improve the quality of the product at lower cost. Reasons for not automating 1.labour resistance People look at robots and manufacturing automation as a cause of unemployment. In reality, the use of robots increases productivity, makes the firm more competitive and preserves jobs. But some jobs are lost. On the other hand, the real cause of layoffs today is not automation or the migration of jobs because of cheap labour elsewhere. The top layoffs can be attributed mainly to competition, mergers, and government spending cuts. 2. Cost of upgraded labour the routine monotonous tasks are the easiest to automate. The tasks that are difficult to automate are ones that require skill. Thus manufacturing labour must be upgraded. 3. Initial investment cash flow considerations may make an investment in automation difficult even it the estimated rate of return is high. Higher output and increased productivity have been two of the biggest reasons in justifying the use of automation. …

In our world are a lot of animals. Some of them live their usual life. Others are threatened of extinction. They live only in theirs specific areas. Some of them are just on extinction, but there are a lot of which number of population is really small. Animals which are on extinction are the following: stoats (šermuonėlis), seals (ruonis), white hares (baltasis kiškis), black storks and grass snakes. They are threatening of extinction because of some reasons. First and the most important reason is that these animals haven’t got fitted to them residence. They live in uninhabitable areas. They haven’t got specific food, and they can’t adapt to alterable living conditions. Second reason why there are endangered animals is that man's mastery over his environment is really huge. First here are a lot of factories and companies which are polluting air and water. Second there are cutting down forests on a mass scale. One more human’s harm is that hunters are hunting some animals for their fur, skin or bones. Animals are vanishing apace, and if we don’t take measures animals will disappear and it is unstoppable. So what should we done? First I think we have to try to reduce air and water pollution. We have to try to live cleanly. We ought to stop littering and using chemicals. Second way how to protect these vanishing animals is to transpose them to the zoo or into their specific and fitted areas. In these areas they can live their normal lives. To sum up I want to say that all of us have to understand that if these animals will disappear we can’t restore them.

. On both sides of the border, cars and trucks are the main sources for nitric acid(about 40% of the total), while power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre©Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one. This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. ACID The average mean of pH rainfall in Ontario's Muskoka©Haliburton lake country ranges between 3.95 and 4.38 about 40 times more acidic than normal rainfall, while storms in Pennsilvania have rainfall pH at 2.8 it almost has the same rating for vinegar. Already 140 Ontario lakes are completely dead or dying. An additional 48 000 are sensitive and vulnerable to acid rain due to the surrounding concentrated acidic soils.Ô ACID RAIN CONSISTS OF....? Canada does not have as many people, power plants or automobiles as the United States, and yet acid rain there has become so severe that Canadian government officials called it the most pressing environmental issue facing the nation. But it is important to bear in mind that acid rain is only one segment, of the widespread pollution of the atmosphere facing the world. Each year the global atmosphere is on the receiving end of 20 billion tons of carbon dioxide, 130 million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons of nitrogen oxides, more than three million tons of arsenic, cadmium, lead, mercury, nickel, zinc and other toxic metals, and a host of synthetic organic compounds ranging from polychlorinated biphenyls(PCBs) to toxaphene and other pesticides, a number of which may be capable of causing cancer, birth defects, or genetic imbalances. COST OF ACID RAIN Interactions of pollutants can cause problems. In addition to contributing to acid rain, nitrogen oxides can react with hydrocarbons to produce ozone, a major air pollutant responsible in the United States for annual losses of $2 billion to 4.5 billion worth of wheat, corn, soyabeans, and peanuts. A wide range of interactions can occur many unknown with toxic metals. In Canada, Ontario alone has lost the fish in an estimated 4000 lakes and provincial authorities calculate that Ontario stands to lose the fish in 48 500 more lakes within the next twenty years if acid rain continues at the present rate.Ontario is not alone, on Nova Scotia's Eastern most shores, almost every river flowing to the Atlantic Ocean is poisoned with acid. Further threatening a $2 million a year fishing industry. Ô Acid rain is killing more than lakes. It can scar the leaves of hardwood forest, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to a state that is vulnerable to disease infestation and decay. In the soil the acid neutralizes chemicals vital for growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil. The rate of forest growth in the White Mountains of New Hampshire has declined 18% between 1956 and 1965, time of increasingly intense acidic rainfall. Acid rain no longer falls exclusively on the lakes, forest, and thin soils of the Northeast it now covers half the continent. EFFECTS There is evidence that the rain is destroying the productivity of the once rich soils themselves, like an overdose of chemical fertilizer or a gigantic drenching of vinegar. The damage of such overdosing may not be repairable or reversible. On some croplands, tomatoes grow to only half their full weight, and the leaves of radishes wither. Naturally it rains on cities too, eating away stone monuments and concrete structures, and corroding the pipes which channel the water away to the lakes and the cycle is repeated. Paints and automobile paints have its life reduce due to the pollution in the atmosphere speeding up the corrosion process. In some communities the drinking water is laced with toxic metals freed from metal pipes by the acidity. As if urban skies were not already grey enough, typical visibility has declined from 10 to 4 miles, along the Eastern seaboard, as acid rain turns into smogs. Also, now there are indicators that the components of acid rain are a health risk, linked to human respiratory disease. PREVENTION However, the acidification of water supplies could result in increased concentrations of metals in plumbing such as lead, copper and zinc which could result in adverse health effects. After any period of non©use, water taps at summer cottages or ski chalets they should run the taps for at least 60 seconds to flush any excess debris. Ô STATISTICS Although there is very little data, the evidence indicates that in the last twenty to thirty years the acidity of rain has increased in many parts of the United States. Presently, the United States annually discharges more than 26 million tons of suffer dioxide into the atmosphere. Just three states, Ohio, Indiana, and Illinois are responsible for nearly a quarter of this total. Overall, twoªthirds of the suffer dioxide into the atmosphere over the United States comes from coal©fired and oil fired plants. Industrial boilers, smelters, and refineries contribute 26%; commercial institutions and residences 5%; and transportation 3%. The outlook for future emissions of suffer dioxide is not a bright one. Between now and the year 2000, United States utilities are expected to double the amount of coal they burn. The United States currently pumps some 23 million tons of nitrogen oxides into the atmosphere in the course of the year. Transportation sources account for 40%; power plants, 30%; industrial sources, 25%; and commercial institutions and residues, 5%. What makes these figures particularly distributing is that nitrogen oxide emissions have tripled in the last thirty years. FINAL THOUGHTS Acid rain is very real and a very threatening problem. Action by one government is not enough. In order for things to be done we need to find a way to work together on this for at least a reduction in the contaminates contributing to acid rain. Although there are right steps in the right directions but the government should be cracking down on factories not using the best filtering systems when incinerating or if the factory is giving off any other dangerous fumes.

It was Christmas Eve and Mrs. Wilson, an elderly woman, was sitting in her rocking chair, listening to Christmas carols on her radio. This was a family tradition that went on for many, many years. Christmas just wasn't Christmas in the Wilson household without listening to carols on the radio. "Oh my!" she sighed. "I'm so lonely. I wish my son, Paul were here to share Christmas with me!" Mrs. Wilson lived alone in a small apartment. This particular Christmas was very rough on her. Normally, Christmas was spent with Paul, his wife Nelly, and their son Johnny. However, this could not happen this Christmas. Paul had lost his wife and son in a car accident earlier that fall. It was a very difficult time for Mrs. Wilson, but especially for Paul. Oh how he had loved his wife and child! A few days ago, Mrs. Wilson had called her son to ask him to join her for Christmas. "Ma, I can't," Paul had told her. "I miss them so terribly. I keep expecting them to show up at the doorstep." "Oh Paul," cried Mrs. Wilson. "I know this is difficult for you, but do you honestly think that you should be alone at a time like this." "I don't know," said Paul. "Right now, yeah, I do think that being alone is the answer." "Well dear," she replied sadly. "If you change your mind, I'll be here." "Thanks Ma," said Paul. "And, Ma, Merry Christmas." "Merry Christmas to you too, son," said Mrs. Wilson. The radio program was just finishing up for the night. Mrs. Wilson, yawning, got up and turned it off. "The radio program just wasn't the same this year," she sighed as she went into her bedroom. "It's just not the same without Paul, Nelly and Johnny. I sure wish Paul would change his mind." Later that night, she was awakened by a strange sound coming from her living room. Quickly, she grabbed her house coat and went to see what was going on. There, standing by the Christmas tree, with his arms full of presents, was Paul. "Oh Paul!" cried Mrs. Wilson. "I'm so glad to see you." She embraced her son as tightly as she could. "I just got to thinking that maybe being alone wasn't the right thing," said Paul. "After all, aren't we supposed to spend Christmas with family." "Yes, dear, we are," said Mrs. Wilson, happily. "I'm so glad you came." "You know," said Paul. "I'm glad I did too." "Can I get you something to eat, Paul?" asked Mrs. Wilson. "I have some apple pie and ice-cream." "Now that sounds good," said Paul. "Come to think of it, I'm starved." Mrs. Wilson dished Paul out a heaping dish full of homemade apple pie and a huge serving of vanilla ice-cream.

It is necessary to know the history, culture, traditions of the country which language, you study. It is very difficult to learn any foreign language when you do not hear it in the street at house. The film which we see on TV are translated into native language and we can’t hear the English language. The English language is very popular in the world and what country you visit you can communicate in England. The role of the foreign languageshas inereased in the last years, as Lithuanian keeps good relations with other European countries and is going to biome a member of European Union and NATO. So every young person must think about his future and the use of the foreign language. The European Union(apie europos sąjungą) The European Union is the European supranational organization dedicated to increasing economic integration and strengthening co-operation among its member states.

Pirmiausia reikia išsiaiškinti, kas yra socialinis pedagogas, kokios jo funkcijos? Kas būdinga asmenybei? G. Kvieskienė (Kvieskienė, 2003) yra pasakiusi labai prasmingą teiginį, jog socialiniai pedagogai – vaiko gerovės sergėtojai ir vaiko advokatai – siekia apsaugoti tuos, už kuriuos atsako, tai yra mažiausius ir silpniausius piliečius. Šio tikslo jie siekia pasitelkdami humanizmo mąstytojų idėjas, iškiliausių praktikų pedagogų, altruistų, dvasinės sferos darbuotojų atsidavimą begalinei būčiai, aukojimąsi visoms būties apraiškoms. Socialinis pedagogas spręsdamas kitų problemas pirmiausia pasitelkia savo jėgomis, sugebėjimu greitai orientuotis situacijoje, savo erudicija.

Channel allocation problem: static channel allocation, frequency division multiplexing - FDM - bandwidth of channel is divided into N equal sized portions, time division multiplexing - each user is statically allocated every Nth time slot, both techniques are very inefficient for environments with variable number of users and bursty traffic. Multiple Access Protocols: pure ALOHA, nodes can transmit frames at any instance of time, collisions are allowed - contention system, uniform frame size for all nodes.
