【正文】 body and so the heat is sent off little by little. Muscles always make energy. Sometimes more, sometimes less. When you exercise, they are more active and so make more heat. When you are losing heat quickly, the best thing to do is to run slowly around. If you do not, you will shiver. That is the other way the muscles make heat. Another way of saying this is the muscles move quickly backwards and forwards. Next time you shiver, try running a bit. You will find that after two or three minutes the shivering will stop. It is because running helps your muscles make more heat, so shivering is no longer needed to maintain body temperature. 1 muscles 肌肉 2 oxygen 氧 3 carbohydrates 碳水化合物 4 energy 能量 5 process 進(jìn)程 56．“ Through cold” in “ But still you shiver, and your teeth knock together through cold” means: A. during cold weather B. because of cold C. when it is cold D.

It will also be able to translate(翻譯 ) any language for you. So give up going to classes and stop buying more textbooks. In a couple of years you won’ t need the international language of English. Imagine(設(shè)想 ) a Chinese secretary, for example, who wants to type a letter from the boss to a businessman in Britain. All he or she will have to do this: first type the letter in Chinese. The letter will appear on a television screen. After a few seconds the translated letter will appear on another television screen in London in perfect English. And that’ s not all. Soon a puter will teach you English, if you really want to learn the language. You’ ll sit in front of a television screen and practise. The puter will tell you when you are correct and when you are wrong. It will even talk to you. So think of it. You will be able to teach yourself at your won pace(進(jìn)度 ). You will waste very little time, and you can work at home. And if after all that, you still can’ t speak English you can always use the translation machine. In a few years, perhaps there will be no need for BBC Modern English, or BBC English by Radio programmes— no more textbooks or teachers of English. Instead of buying an exciting new textbook, the puter will ask you to replace it with the microprocessor(微型處理器 ). One little problem is that a puter can’ t laugh yet— but the scientists are working on it. Happy learning! 61． According t
