When we see well, we do not think about our eyes very often. (79) It is only when we cannot see perfectly that we realize how important our eyes are.
People who are nearsighted can only see things that are very close to their eyes. Everything else seems blurry (模糊的). Many people who do a lot of close work, such as writing, reading and sewing, become nearsighted. Then they have to wear glasses in order to see distant objects clearly.
People who are farsighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.
Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people olden became blind. Now, however, it is possible to operate on the cataracts and remove them.
Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distance as people with two eyes.
We should take good care of our eyes ______.
A．only when we can see well
B．only when we cannot see perfectly
C．even if we can see dell
D．only when we realize how important our eyes are

Suppose a man wanted to reach a distant star. Even if he traveled his whole life, he would have to move faster than the speed of the light. Nothing can move that fast except light itself.
Strange things happen to an object when it moves rapidly. The object weighs more. An object moving at 86 percent of the speed of light is twice as heavy as it is at rest. A stick appears shorter. A clock runs more slowly. A man would not age so fast as he would on the earth.
Light travels more than 186,000 miles a second, or about 11 million miles a minute. In one year, light travels six trillion miles. That great distance is called a light-year. It is used to measure distance in space.
The star closest to our sun is Alpha Centauri. It is more than four light-years away. If one traveled at the speed of light, he could make a round trip to Alpha Centauri in nine years. But, even at that speed, he could not reach Alcaid (北斗星) in the handle of the Big Dipper. A one-way journey to Alcaid would take almost 200 years
1．In this passage the words “closest to our sun” means the star（）.
A、the earth we live on

D、the moon
2．A one-way journey to Alcaid would take（）.
A、about nine years
B、less than four years
C、almost 200 years
D、less than 100 years
3．Why do we measure the distance in light-years instead of miles?（）
A、Units of light-years sound better.
B、Using light- years reduced the number of figures used.
C、We used to measure distance in light-years long ago.
D、We do not make mistakes when we use light-years.
4．If a stone moved at the speed of light, it（）.
A、would weigh twice more than it is motionless
B、would weigh as much as it is on earth

In many modem countries it has for some time been fashionable to think that, by free education for all-whether rich or poor, clever or stupid--one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough; we find in such countries a far larger number of people with university degrees than there are jobs for them to fill. Because of their degrees, they refuse to do what they consider" low" work; and, in fact, work with the hands is thought to be dirty and shameful in such countries.
But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor, We can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we would have terrible diseases in our towns. In countries where there are no servants because everyone is ashamed to do such work, scientists have to waste much of their time doing housework.
In fact, when we say that all of us must be educated to prepare for life, it means that we must be educated in such a way that, firstly, each of us can do whatever job is suited to his brain and ability and, secondly, that we can realize that all jobs are necessary to society, and it is very bad to be ashamed of one's work, or to scorn someone else's. Only such a type of education can be called valuable to society.
Education is ______.
A．a means
B．a purpose
C．fashionable
D．the first system
To squeeze the most out of each shining hour we have shortened the opera, quickened the pace of the movie and put culture in pocket-sized packages. We make the busy bee look like a lazy creature, the ant like a sluggard. We live sixty-mile-minute and the great efficiency smiles.
We wish we could return to that pleasant day when we considered time a friend instead of an enemy; when we did things willingly and because we wanted to, rather than because our timetable called for it, But that of course would not be efficiency; and we Americans must be efficient.
The phrase that best expresses the main idea of this passage is ______. ()
A．the modern pace
B．our interest in shortened operas
C．how to make the best use of leisure time
D．planning our time scientifically
Psychologists have discovered that even the most independent-minded of us will conform. to social pressure when we are with a group of people. In one classie experiment, people were showna vertical line and asked to find a line of identical length from a selection of three.
You might think that this is an absurdly easy task, and when people perform. it by themselves they do it very well. However, psychologists have discovered that we are very easily swayed by the opinions of other people when we do this task in a group. In one study, a group of three people was set up,where two of the people were confederates(同伙 )of the experimenter.When the confederates deliberately gave wrong answers,people were often swayed to give the wrong answer also. In fact, 75% of people gave at least o ne wrong answer, with some people conforming to peer pressure on every occasion.
But why do people conform. in this way？ In an easy task like this, it seems that people do not want to step out of line with the prevailing opinion of the group. On more difficult tasks, people also conform. because they lose onfidence in their own ability to make decisions and prefer to trust the majority opinion instead.
A typical example of this kind of conformity arises when we come across people in distress. Would you help a woman who has been attacked in the street？It turns out that you are much more likely to go to her assistance if you are alone.When other people are also around,a diffusion of responsibility occurs. People are paralysed into inaction, because everyone assumes that someone else will go to the woman' s assistance.
25. In Paragraph 1, the underlined word "conform" probably means“ ()”.
A.seek independence
B.disobey orders
C.seek pleasure
D.follow what others do
26.What is the purpose of the experiment described in Paragraph 2？ To().
A.explain why people would be influenced by the opinions of others
B.prove that people are easily influenced by the opinions of others
C.train the confederates of the experimenter as independent-minded
D.describe how people would be influenced by the opinions of others
27.In the last paragraph, according to the author,why wouldn’t one help the woman ？He().
A.thinks he has no responsibilities to give a hand
B.thinks he has has nothing to do with it
C.is too shy to give his helping hand
D.thinks someone else will offer assistance
28.What method does the author mainly use to develop the text？ (
A.Giving examples.
B.Cause-effect analysis.
C.Comparative analysis.
D.Process analysis.
A yellow room makes us feel more cheerful and more comfortable than a dark green one. On the other hand, black is depressing. Light and bright colors make people not only happier but more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark gray.
Remember that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.
According to this passage,______.
A．one can choose his color preference
B．one is born with his color preference
C．one's color preference is changeable
D．one has to choose his favorite color as soon as he can see clearly
We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.
But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.
