If it were only necessary to decide whether to teach elementary science to everyone on a m

ass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school system, however, has no such choice, for the jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services.

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

第6题

Settlers of the Plains also had to contend with social isolation. The European pattern, wh

ereby farmers lived together in a village and traveled each day to their nearby fields, was rare in the American West. Instead, various peculiarities of land division compelled the rural dwellers to live apart from each other. The Homestead Act of 1862 and other measures adopted to facilitate western settlement offered free or cheap plots to people who would live on and improve their property. Because most homesteads and other plots acquired by small farmers were rectangular--usually encompassing 160 acres--at most four families could live near each other, but only if they congregated around the same four-corner boundary intersection. In practice, farmers usually lived back from their boundary lines, and at least a half-mile separated farmhouses. Often adjacent land was unoccupied, making neighbors even more distant.

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."

Few Americans remain in one position or one place for a lifetime. We moving from town to c

ity to suburb, from high school to college in a different state, from a job in one region to a better job elsewhere, from the home where we raise our children to the home where we plan to live in retirement. With each moving we are forever making new friends, who become part of our new life at that time.

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______.

A．saving money

B．getting a better job

C．going to college

D．finding a place to spend the rest of the life

When aluminum was first produced about a hundred and fifty years ago, it was so difficult

to separate from the ores(矿石) in which it was found that its price was higher than that of gold. The price remained high until a new process was discovered for refining the metal with the aid of electricity approximately three quarters of a century later. The new method was so much cheaper that aluminum became practical for many purposes, one of which was making pots and pans.

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

D．electricity

So【50】he looks hard at the sea it will be【51】for him to know how fast his ship is moving or indeed if it is moving at all. Of course, if the sea should get rough or the ship changes course suddenly,【52】he will sense his state of motion. But even supposing that we have the idealized conditions of a glass calm sea and a silent ship, nothing that happens below decks -- no amount of observation or mechanical experiment performed inside the ship --will reveal its velocity through the sea.

第11题

Today, moving and changing are as much a part of a modern business way of life as they are

a part of the native American's or the early pioneer's way of life. And the trend is toward even greater mobility, particularly within the management sector of American business.

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
