In the ancient world, as today, most boys played with some kinds of toys and most girls with some other. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world. What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained the same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all part of the world and their persistence to the present that is amazing. In Egypt, America, China, Japan, and even among the Arctic peoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles. (4) A．Because boys and girls are being prepared for different social roles. B．Because boys are more courageous. C．Because toy makers want to diversify their products. D．Because parents have different expectations for boys and girls.

Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins. Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years. The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes. "This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C.. No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says. If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective. But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'." Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction. According to the passage, which of the following is NOT true？ A．Eating less than usual might make us live longer. B．If we go on a diet when old, we may keep healthy. C．Dieting might not be needed. ~ D．We have to begin dieting from childhood.

A stage is actually a box. One side of the box has been removed so the audience can see what's going on inside. The actors remain at a fixed audience. In the film, however, the camera can bring the audience up close and fix their attention on small but important things: a frightened look, a whisper, a trembling of hands. The camera offers the film maker freedom allowing him to move easily across barriers (界限) of time and space. He can show his action in real cities and on real farms. He can also use the camera to change the scene dozens of times in one film. No expert of the stage can do this. The main idea of the text is that______. A．stage plays and films are two different kinds of art B．it is always disappointing to turn play into films C．films have certain advantages over stage plays D．the camera has made film making easy and possible

A．The man will probably have to find a roommate. B．The man is unlikely to live in the suburbs. C．The man will probably have to buy a car. D．The man is unlikely to find exactly what he desires.

People may be the most interesting show in a large city. Stroll through busy streets and see what everybody else is doing. You will probably see people from all over the world; you will certainly see people of every age, size, and shape, and you'll get a free fashion show, too. Window—shopping is also a safe sport—is the stores are closed. Check the listings in your neighborhood paper. Local colleges or schools often welcome the public to hear an interesting speaker or a good debate. The film or concert series at the local public library probably won't cost you a penny. Be sure to check commercial ad vertisements too. A flea market can provide hours of pleasant brow sing. Perhaps you can find a free cooking or crafts in a department store. Plan ahead for some activities. It is always more pleasant not to have people in front of you in a museum or at a zoo. You may save some money, too, since these places often set aside one or two free admission days at slow times during the week. (79) Pretend that you are a tourist from time to time, and get to know your city all over a gain including the indispensable (不可错过的) sights that people travel miles to see.

In practice, what often happens is that a new theory is devised that is really an extension of the previous theory. For example, very accurate observations of the planet Mercury revealed a small difference between its motion and the predictions of Newton's theory of gravity. Einstein's general theory of relativity predicted a slightly different motion from Newton's theory. The fact that Einstein's predictions matched what was seen, while Newton's did not, was one of the crucial confirmations of the new theory. However, we still use Newton's theory for all practical purposes because the difference between its predictions and those of general relativity is very small in the situations that we normally deal with. (Newton's theory also. has the great advantage that it is much simpler to work with than Einstein's ! ) It turns out to be very difficult to devise a theory to describe the universe all in one go. Instead, we break the problem up into bits and invent a number of partial theories. Each of these partial theories describes and predicts a certain limited class of observations, neglecting the effects of other quantities, or representing them by simple sets of numbers. It may be that this approach is completely wrong. If everything in the universe depends on everything else in a fundamental way, it might be impossible to get close to a full solution by investigating parts of the problem in isolation. Nevertheless, it is certainly the way that we have made progress in the past. The classic example again is the Newtonian theory of gravity, which tells us that the gravitational force between two bodies depends only on one number associated with each body, its mass, but is otherwise independent of what the bodies are made of. Thus one does not need to have a theory of the structure and constitution of the sun and the planets in order to calculate their orbits: Today scientists describe the universe in terms of two basic partial theories-the general theory of relativity and quantum mechanics. They are the great intellectual achievements of the first half of this century. Unfortunately, however, these two theories are known to be inconsistent with each other-they cannot both be correct. One of the major endeavours in physics today, is the search for a new theory that will incorporate them both-a quantum theory of gravity. We do not yet have such a theory, and we may still be long way from having one, but we do already know many of the properties that it must have. According to the passage, why can't any physical theory be permanently established？ A．Such a theory is only suggested as a possible way of explaining an idea. B．The person proposing such a theory may be incompetent. C．Observations always disagree with predictions. D．Observations are always falsified by predictions.

One company gives every employee over 50 years old and who has been with them for 25 years, six months’ holiday on full pay.At the same time additional money can be made available by way of loans, to help them with projects they cannot otherwise offer.Most of the people who have already benefited from the scheme, have used the opportunity to travel to distant places like the Far East or South America and some have spent the money on their favorite hobbies, such as photography. The cost of providing these special holidays is fairly high but the directors feel it is well worthwhile because the employees are greatly refreshed by their long break from the pressures and routines of their jobs.The only problems are that the people concerned tend to have key jobs which can be difficult to fill on a temporary basis for a relatively long time.Besides, some employees find it difficult to re-adjust to the old routine after such a long time away.In addition, one or two people may not feel secure at leaving their job in someone else’s hands.On balance, however, there is no doubt that the idea is beneficial to industrial relations and a wonderful reward for long service. 31.Many workers would like to ___________. A.dream of long holidays at home B.spend a long time in unusual places C.buy a holiday away from home D.have a long holiday after many years 32.One company____________. A.gives money to employees over 25 years B.lends staff money to go on holidays C.allows long holidays to certain staff D.arranges long holidays for old employees 33.Most of the employees in the scheme ____________. A.take foreign trips B.develop their hobbies C.take up photography D.enjoy leisure activities 34.The directors feel that _____________. A.the staff get a lot of pleasures from the scheme B.older staff are very enthusiastic about holidays C.the scheme is more expensive than they expected D.the scheme is beneficial to staff relations 35.One of the problems is that ________________.
