After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for Rapid Eye Movement.If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep! During REM, ().
Peter White: We’re facing a serious energy crisis. All known reserves of coal, oil and gas will be exhausted within ten years. It is imperative that we develop new sources of energy immediately. Nuclear power is the answer to our problems. If we don’t build nuclear power station now, our civilization will collapse. Bob Robin: We can’t allow this power station to be built. I’ll tell you why. It would cause terrible damage to the environment and all living creatures in the district would be in great danger. A small leak could cause a disaster. It is our duty as responsible citizens to force the government to abandon their nuclear energy program. Mark Brewer: This power station will be absolutely safe. They’ll be no danger of leakage because the reactor will be housed in a concrete box with wails six meters thick. Five independent alarm systems will monitor every square centimeter of the power station to prevent fire or sabotage. People are afraid of nuclear power because they don’t understand it. We must educate them. Nuclear power is clean, quiet, cheap and pollution-free, unlike conventional power using gas, oil and coal. Furthermore, it is almost unlimited. Harry Wells: I used to believe nuclear power stations were safe. But last month-1 saw a top-secret government report which revealed at least five major leaks in the last two years. In each case, the alarm systems afraid and there could have been a disaster. Scientists have too much faith in their own ideas and have helped the government to deceive the public. I think it’s time that the truth was told. Nuclear power stations are indeed very dangerous. Joe Forest: I think the government is placing too much emphasis on nuclear power. I mean, it’ll take many more years of experimentation before the safety problem alone is overcome. In the meantime, I think we should develop other ways of taking energy from the earth, such as sunshine, or the tide, waves, rivers, hot springs, etc. There are lots of alternative forms of energy. They are cheaper, safer and more convenient than nuclear power. Now match each of the persons to the appropriate statement. Note: There are two extra statements. Statements A. People have put nuclear energy to constructive uses, and also have put it to destructive uses. B. Other ways of taking energy should be developed until the safety problem associated with nuclear power is overcome. C. People should be educated to know that there’ll be no danger of leakage of nuclear power and that it is not like conventional power. D. Without nuclear power stations human society would stop functioning. E. Nuclear energy is safe when it is controlled and it can be made a useful form of energy. F. The government should tell the public the truth that nuclear power stations are indeed very dangerous. G. Nuclear power can cause terrible damage to the environment and put all living creatures in great danger. Peter White
I don’t know how I became a writer, but I think it was because of a certain force in me that had to write and that finally burst through and found a channel. My people were of the working class of people. My father, a stone-cutter, was a man with a great respect and veneration for literature. He had a tremendous memory, and he loved poetry, and the poetry that he loved best was naturally of the rhetorical kind that such a man would like. Nevertheless it was good poetry, Hamlet’s Soliloquy, Macbeth, Mark Antony’s Funeral Oration, Grey’s Elegy, and all the rest of it. I heard it all as a child; I memorized and learned it allHe sent me to college to the state university. The desire to write, which had been strong during all my days in high school, grow stronger still. I was editor of the college paper, the college magazine, etc, and in my last year or two I was a member of a course in playwriting which had just been established there. I wrote several little one-act plays, still thinking I would become a lawyer or a newspaper man, never daring to believe I could seriously become a writer. Then I went to Harvard, wrote some more plays there, became obsessed with the idea that I had to be a playwright, left Harvard, had my plays rejected, and finally in the autumn of 1926, how, why, or in what manner I have never exactly been able to determine. But probably because the force in me that had to write at length sought out its channel, I began to write my first book in London. I was living all alone at that time. I had two rooms -- a bedroom and a sitting room -- in a little square in Chelsea in which all the houses had that familiar, smoked brick and cream-yellow-plaster look. The author believes that he became a writer mostly because of ().
