In education, there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative emphases among the natural sciences themselves.
Similarly, we must have a balance between current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to mm our attention away from the sound, established materials that form. the basis of courses for beginners.
According to the first paragraph, the task of education is fairly complicated because ______.
A.the current public school system is too complicated to be understood
B.the public school system has no choice of what to teach
C.it is difficult to decide whether elementary science should be taught in public schools
D.the educators have to take care of both ordinary and gifted students

Those who criticize economic growth argue that we must slow down. They believe that society is approaching certain limits on growth. These include the fixed supply of natural resources, the possible negative effects of industry on the natural environment, and the continuing increase in the world's population. As society reaches these limits, economic growth can no longer continue, and the quality of life will decrease.
People who want more economic growth, on the other hand, argue that even at the present growth rate there are still many poor people in the world. These proponents of economic growth believe that only more growth can create the capital needed to improve the quality of life in the world. Furthermore, they argue that only continued growth can provide the financial resources required to protect our natural surroundings from industrialization.
This debate over the desirability of continued economic growth is of vital importance to business and industry. If those who argue against economic growth are correct, the problems they mention cannot be ignored. To find a solution, economists and the business community must pay attention to these problems and continue discussing them with one another.
What is this passage primarily concerned with?
A.The problems caused by economic growth.
B.The desirability of economic growth.
C.The desire for more material wealth.
D.The limits of economic growth.

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

Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.
There is a saying that it is so noisy that you can't hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don't, we may have headaches, other aches and pains, or even worse mental problems.
Noise adds more tension to a society that already faces enough stress.
But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots(战车) from moving through the streets at night!
Ways of making less noise are now being tested. There are even laws controlling noise. We cannot return to the "good old days" of peace and quiet. But we can reduce noise—if we shout loudly enough about it.
Why are scientists surprised by the findings in their noise study?
A.Because the world is becoming increasingly noisy.
B.Because they have learned that noise is also is also a kind of pollution.
C.Because noise is an unwanted waste for human beings.
D.Because people knew little about noise before.
