What will man be like in the future -- in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity . As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too: the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and motions similar to our own. The passage mainly tells us that _ . A) Man's life will be different in the future B) Future man will look quite different from us C) Man is growing taller and uglier as time passes D) Man's organs' functions will change

Smoking is the single worst thing you can do for your health. Fortunately, it's never too late to get the benefits of quitting. If you've tried to quit before and failed, it's time to make up your mind and try again. Smoking is responsible for one of every five deaths. That includes 29% of all cancer deaths, 87% of all lung cancer deaths, and nearly 20% of all deaths from cardiovascular disease. But long before smoking kills you, it ages you. You can see for yourself that smoking accelerates the drying and wrinkling of the skin. But there are less obvious effects as well. Indeed, smoking takes years away from your life. Nearly half of all chronic smokers die an average of 20 to 25 years before their time. Besides an early death from cancer or heart disease, smoking can cause lung disorders. People who smoke over a pack a day have almost three times the risk of contracting pneumonia than that of nonsmokers. By lowering levels of estrogen in men and women, smoking speeds bone less. If a woman smokes a pack of cigarettes every day, she will enter menopause with 5 to 10% less bone mass than a nonsmoker. The good news is that no matter what your age is or how long you've smoked, you'll live longer if you quit today. The Coronary Artery Surgery Study examined nearly 2,000 long-term smokers over age 54. Those who quit had significantly lower death rates six years later than those who didn't. Even the oldest ex-smokers had a higher survival rate. Not only will live longer if you quit, you'll feel better, breathe easier, and find that you have more energy. You'll have fewer respiratory infections,headaches, and stomachaches. What's more, you'll save money. Your clothes and breath won't smell unpleasant any longer. And your habit won't annoy--or threaten the health of --the people who live and work with you. According to the passage, the percentage of deaths due to smoking is _ . A) 20% B) 25% C) 29% D) 87%

Nearly all our food comes from the soil. Some of us eat meat, of course, but animals live on plants. If there were no plants, we would have no animals and no meat. So the soil is very necessary for life. The top of the ground is usually covered with grass or other plants. There may be dead leaves and dead plants on the grass. The waste matter from animals also falls on it. All soil needs food. If we do not give it any, the plants will be weak. Farmers found that animals' waste is the best food for the soil, but chemical fertilizers are also very useful. The same crop should not be grown in the same place every year; it's better to have a different crop. A change of crop and the use of a good fertilizer will keep the land good. What is the best title for the passage? A) Soil and Waste B) Plants and Animals C) Food and Waste D) Soil and Food
