Millions of stars are traveling about in space. A few form. groups which journey together, but most of them travel alone. And they travel through a universe so large that one star seldom comes near to another.
We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun. Just as the sun and the moon raise tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave' must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).
Millions of stars are______.
A．following a regular path in space
B．always travelling together
C．seldom wandering about in the universe
D．moving about without a fixed course

In what now seems like the prehistoric times of computer history, the earth's postwar era, there was quite a wide-spread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are faced with a less dramatic but also less foreseen problem. People tend to be over-trusting of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons may be pushed, or that a computer may simply malfunction.
Obviously, there would be no point in investing in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong.
Questioning and routine double-checks must continue to be as much a part of good business as they were in pre-computer days. Maybe each computer may provide; it should not be seen as a substitute for fundamental thinking and reasoning skills.
What is the main purpose of this passage？
A．To look back to the early days of this passage.
B．To explain what technical problems may occur with computers.
C．To discourage unnecessary investment in computers.
D．To warn against a mentally lazy attitude towards computers.

In any country the wages commanded by laborers who have comparable skills but who work in various industries are determined by the productivity of the least productive unit of labor, i.e., that unit of labor which works in the industry which has the greatest economic disadvantage. We will represent the various opportunities of employment in a country like the United States by symbols: A, standing for a group of industries in which we have exceptional, economic advantages over foreign countries; B, for a group in which our advantages are less; C, one in which they are still less; D, the group of industries in which they are least of all.
When our population is so small that all our labor can be engaged in the group represented by A, productivity of labor (and therefore wages) will be at their maximum. When our population increases so that some of the labor will have to be set to work in group B, the wages of all labor must decline to the level of the productivity in that group. But no employer, without government aid, will yet be able to afford to hire labor to exploit the opportunities represented by C and D, unless there is a further increase in population.
But suppose that the political party in power holds the belief that we should produce every thing that we consume, that the opportunities represented by C and D should be exploited. The commodities that the industries composing C and D will produce have been hitherto obtained from abroad in exchange for commodities produced by A and B. The government now renders this difficulty by placing high duties upon the former class of commodities. This meads that workers in A and B must pay higher prices for what they buy, but do not receive higher prices for what they sell.
After the duty has gone into effect and the prices of commodities that can be produced by C and D have risen sufficiently, enterprisers will be able to hire labor at the wages prevailing in A and B, and establish industries in C and D. So far as the remaining laborers in A and B buy the products of C and D, the difference between the price which they pay for those products and the price that they would pay if they were permitted to import those products duty-free is a tax paid not to the government, but to the producers in C and D, to enable the latter to remain in business. It is an uncompensated deduction from the natural earnings of the laborers in A and B. Nor are the workers in C and D paid as much, estimated in purchasing power, as they would have received if they had been allowed to remain in A and B under the earlier conditions.
When C and D are established, workers in these industries______.
A．receive higher wages than do the workers in A and B
B．receive lower wages than do the workers in A and B
C．are not affected so adversely by the levying of duties as are workers in A and B
D．receive wages equal to those workers in A and B

Dreams are a product of the sleeper's mind.They include events and feelings that he has experienced.Most dreams are related to events of the day before the dream and strong wishes of the dreamer.Many minor incidents of the hours before sleep appear in dreams.Few events more than two days old turn up.Deep wishes or fears-especially those held since childhood-often appear in dreams, and many dreams fulfill such wishes.Events in the sleeper's surrounding-a loud noise, for example, may become part of a dream, but they do not cause dreams.
Some dreams involve deep feelings that a person may not realize he has.Psychiatrits often use material from a patient's dreams to help the person understand himself better.
