What will man be like in the future—in 5000 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 a relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modem world we use our brains a great deal. Even so, we still make use of only about 20% of the brain’ s capacity(容量). As time goes on , however , we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about 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 a very 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（敏感的） 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 emotions 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．human’s organs’ functions will become weak “ |

| B．his brain has grown larger over the past centuries. |
| C．the other 80% of his brain will grow in due time |
| D．he will use his brain more and more as time goes on : |
What will be true about a human being in the future?
| A．He will be hairless because hair is no longer useful. |
| B．He will have smaller eyes and will wear better glasses. |
| C．His fingers will grow weaker because he won’t have to make use of them. |
| D．He will think and feel in a different way. |

John H. Johnson was born in a black family in Arkansas city in 1918. His father died in an accident when John was six. He was reaching the high school age, but his hometown offered no high school for blacks.
Fortunately he had a strong-willed (意志坚强的) caring mother. John remembered that his mother told him many times, “Son, you can be anything you want really to be if you just believe.”She told him not to depend on others, including his mother. “You have to earn success, ”she said. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words came from a woman with less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son, who was then 15, to Chicago.
Chicago in 1933 was not the promised land that black southerners were looking for. John’s mother and stepfather could not find work. But here John could go to school, and here he learned the power of words—as an editor of the newspaper and yearbook at Du Sable High School His wish was to publish a magazine for blacks.
While others discouraged him, John’s mother offered him more words to live by.“Nothing beats a failure but a try. ”She also let him pawn(典当)her furniture to get the $ 500 he needed to start the Negro magazine.
It is natural that difficulties and failures followed John closely until he became very successful. He always keeps his mother’s words in mind.“Son, failure is not in your vocabulary!”

Making friends is a skill like most skills. It improves with practice. If you want to meet people and make friends, you must be willing to take some action. You must first go where there are people. You won’t make friends staying home alone.
Joining a club or a group, talking with those who like the same things as you do is much easier. Or join someone in some activity.
Many people are nervous when talking to new people. After all meeting strangers means facing the unknown. And it’s human nature to feel a bit uncomfortable about unknown. Most of our fears about dealing with new people comes from doubts about ourselves. We imagine other people are judging us, finding us too tall or too short, too this or too that. But don’t forget that they must be feeling the same way. Try to accept yourself as you are, and try to put the other person at ease. You’ll both feel more comfortable.
Try to act self-confident even if you don’t feel that way. When you enter a room full of strangers, such as a new classroom, walk tall and straight, look directly at other people and smile.
If you see someone you’d like to speak to, say something. Don’t wait for the other person to start a conversation.
Just meeting someone new does not mean that you will make friends with that person—friendship is based on mutual liking and “give and take”. It takes time and effort to develop.The best topic of the passage may be ________.

Ever tried taking smart drugs to perform better in exams? They certainly work. Before last summer's exam, a few of my mates, merely out of curiosity, took a considerable amount of Modafinil, a drug normally used for narcolepsy(嗜眠发作症). Guess what? While I was feeling sleepy, bored by revision, my mates were more focused.
Modafinil is a smart drug that gives a user a feeling of staying awake for hours. It also sharpens the mind, improves memory and helps problem-solving.
But it does more than just keeping you awake. It disturbs your mental system, making you desperate to do what you are doing. You just don't want to do anything else but revise all the time non-stop.
A recent study discovers that healthy people use smart drugs, like Modafinil, to get down to and complete tasks they have been putting off, because these tasks seem more enjoyable when taking these drugs. This might sound like what a stressed student desires. However, the pills have a range of side-effects.
"At present no evidence shows that these drugs are safe in healthy people," as a medical expert puts it, "Ordering online, though easy, is a dangerous way to obtain drugs. You never know what you're actually purchasing. "
In my experience, Modafinil changes people's behaviour too. Over those weeks my friends became different people—in turn aggressive, cold. Even eating became "a waste of time" and so did conversation.
A BBC survey found that of those who had tried smart drugs before, 92% would do so again. My friends say they'd happily do so without considering the practice a form of cheating.
I admit I was curious—but not enough to try it. Seeing the strange behaviour of other users, I feel a little bit upset and scary. Modafinil may promise to change your grades, but it might also change the way you act. Don't say you haven't been warned!According to the author, his mates took Modafinil for the purpose of______.
| A．escaping from reality | B．getting better exam results |
| C．curing their narcolepsy | D．leading an active life |
Taking the smart drug can lead to ______.
| A．cheating in the exam | B．dropping out of school |
| C．youth crime(犯罪) | D．drug addiction(上瘾) |
What does the author think of his mates' taking the smart drugs?
| A．Worrying. | B．Inspiring. |
| C．Acceptable. | D．Reasonable. |
Which statement about Modafinil is wrong?
| A．Modafinil sharpens the mind and helps problem-solving. |
| B．Modafinil more than just keeps you awake. |
| C．Modafinil has a range of side effects. |
| D．Modafinil is safe in healthy people. |

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably associated with environmental damage.
Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation(通货膨胀) is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.
There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long- term health effects to nearby populations of animals, or people. They also lead to global warming.
Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.
In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would Block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.
For these reasons, bringing about economic growth without resulting in any environmental damage is impossible.What does the passage mainly talk about?
| A．Pollution caused by plant construction |
| B．Effects of windmills on the environment |
| C．Economic growth and human civilization |
| D．Economic growth and environmental damage |
According to the passage, the author holds the opinion that ____.
| A．economic growth should be calculated in terms of GDP |
| B．use of natural resources causes no damage to the environment |
| C．industrial manufacturing may cause damage to the environment |
| D．a windmill is a perfect way to produce economically practical energy |
