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.

Throughout history, people have been interested in knowing how language first began, but no one knows exactly where or how this happened. However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by millions of people. On the other hand, some languages in the world have less than one hundred speakers.
There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original (最初的) language of this family was spoken about 4,500 years ago. Many of the present languages of Europe and India are modern forms of the language of 4,500 yeas ago.
Languages are always changing. The English of today is very different from the English of 500 years ago. Some even die out completely. About 1, 000 years ago English was a little-known relative of German spoken on one of the borders of Europe.
If a language has a large number of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by millions of speakers. Their differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China cannot understand speakers from other parts.
The first paragraph mainly tells us that ______.
A．most people in the world speak Chinese
B．there are thousands of languages in the world today
C．man has much knowledge about languages
D．some people know several languages

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

Soldiers and other military people wear uniforms with various other symbols to indicate their status.But in the business world everyone wears more or less similar suits，and you cannot tell at a glance who ranks higher or lower than another.So how do people in the business world show their superiority？ An attempt to study this was made by two researchers using a series of silent films.They had two actors play the parts of an executive(经理)and a visitor，and switch roles each time.The scene had one man at his desk playing the part of an executive，while the other，playing the part of a visitor，knocks at the door，opens it and approaches the desk to discuss some business matter.
The audience watching the films was asked to rate the executive and the visitor in terms of status.A certain set of rules about status began to emerge from the ratings.The visitor showed the least amount of status when he stopped just inside the door to talk across the room to the seated man.He was considered to have more status when he walked halfway up to the desk，and he had the most status when he walked directly up to the desk and stood right in front Of the seated executive.
Another thing that affected the status of the visitor in the eyes of the observers was the time between knocking and entering.For the seated executive，his status was also affected by the time between hearing the knock and answering.The quicker the visitor entered the room，the more status he had.The longer the executive took to answer，the more status he had.

At first glance, there is little in Horton to attract people. The other nearby towns have much more to offer: Bradfield has its river and historic buildings, while Newtown has shops and entertainment. The buildings of Horton look dirty and unloved. For shops, there is a small supermarket, a few bargain shops, a bakery which, strangely, does not sell bread and a florist which has one stand of sadlooking flowers. Even so, Horton has several advantages over its neighboring towns.
Firstly, it has a country park. Four thousand years ago, this was an important fort. There are no historic remains here now, but there are wonderful views over the countryside. On sunny weekends you can often see kids out with their parents, kicking balls or flying kites.
There aren’t many job opportunities in Horton, and the roads to nearby cities aren’t really fast, but there are excellent rail links. You can be in London in an hour and a half, and other cities are less than an hour away. That means that parents can earn a good salary and still get home in time to spend the evenings with their families. Houses in Horton aren’t pretty, but they’re functional and cheap. The streets are quiet and safe, and there are plenty of parks and playgrounds. It has a library, three primary schools and a secondary school, St.Mark’s. It is friendly and offers a wide range of subjects and activities to children of all abilities and backgrounds. The town also has a swimming and a sports centre, and the community halls hold regular clubs and events for people of all ages.
