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.

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

Many observers wrote about the loneliness and monotony of life on the Plains. Men escaped the oppressiveness by working outdoors and taking occasional trips to sell crops or buy supplies. But women were more isolated, confined by domestic chores to the household, where, as one writer remarked, they were "not much better than slaves. It is a weary, monotonous round of cooking and washing and mending and as a result the insane asylum is 1/3 filled with wives of farmers."
For many of us summer is a special time for forming new friendships. Today millions of Americans vacation abroad, and they go not only to see new sights but also with the hope of meeting new people. No one really expects a vacation trip to produce a close friend, but the beginning of a friendship is possible.
The word "friend" can be applied to a wide range of relationships—to someone one has known for a few weeks in a new place, to a fellow worker, to a childhood playmate, to a man or woman, to a trusted confidant (知己) .
The reasons why many Americans move from place to place are as follows except______.

Aluminum is lightweight, rustproof and easily shaped into different forms. By mixing it with other metals, scientist have been able to produce a variety of alloys, some of which have the strength of steel but weigh only one third as much.
Today, the uses of aluminum are innumerable. Perhaps its most important use is in transportation. Aluminum is found in the engines of automobiles, in the hulls of boats. It is also used in many parts of airplanes. In fact, the huge "airbus" planes would probably never have been produced if aluminum did not exist. By making vehicles lighter in weight aluminum has greatly reduced the amount of fuel needed to move them. Aluminum is also being used extensively in the building industry in some countries.
Since aluminum is such a versatile(多用的) metal, it is fortunate that bauxite(铝土矿) , which is one of its chief sources, is also one of the earth's most plentiful substances. As the source of aluminum is almost inexhaustible, we can expect that more and more uses will be found for this versatile metal.
The price of aluminum was sharply reduced when people discovered a new refining process with the aid of______.
A.wind power
B.solar energy
C.hydraulic power

In the early fifties, only eight or nine out of a hundred young men changed their jobs within the first three years with the company. In the past few years, almost thirty-five percent of the college-graduated work force changed jobs within the same period. These people want to intensify their management training. Since most jobs take only a year to a year and a half to master, in order to continue learning, they have to make a job change. Even company presidents tend to be seen as mobile specialists, staying with one company an average of only five years.
Company presidents in the United States today tend to be young men who begin their careers with educational backgrounds in engineering science, or business management. They have worked for a few years as technical specialists and quickly moved into higher management positions. Most of them were making $ 30 000 per year by the time they reached thirty. On an average, these men have only twenty years working experience at management level when they become company presidents. On the way to the top, they have an average of eleven promotions and seven city transfers.
Friendships remain casual and are usually derived from business contracts. Families of these career men have little time to put down roots in and become part of a community.
In the past, a few men attained high positions through family and social connections; today, high positions go to men who are mobile, and have good educational, backgrounds.
According to the passage, an increasing number of future company presidents might be ______.
A.people who have spent a number of years with one company
B.young people who do not want to move often, but are steady and dependable
C.people who have spent a long time concerned with community affairs
D.young people who have good education and are willing to move around
