单选题Play Play is the principal business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy, every child needs opportunity and the right materials for play, and the main tools of play are toys. Their main function is to suggest, encourage and assist play. To succeed in this they must be good toys, which children will play with often, and will come back to again and again. Therefore it is important to choose suitable toys for different stages of a child"s development. In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby"s ability to profit from the right play materials should not be underestimated. A baby, who is encouraged and stimulated, talked to and shown things and played with, has the best chance of growing up successfully. In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toy should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability. Bricks and jigsaws (七巧板)and construction toys; painting, scribbling (涂鸦) and making things; sand and water play; toys for imaginative and pretending play; the first social games for learning to play and get on with others. By the third stage of play development—from five to seven or eight years—the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys. Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books and schools become the main source of learning. Toys are still interesting and valuable, they lead on to new hobbies, but their significance has changed—to a child of nine or ten years, toys and games mean, as to adults, relaxation and fun.

单选题 Weight on and off the Earth We are so used to our life on the surface of the earth that it can be quite an effort for our mind to break free of all the ideas that we take for granted. Because we can feel that things are heavy, we think of "weight" as being a fixed quality in an object, but it is not really fixed at all. If you could take a one-pound packet of butter 4,000 miles out from the earth, it would weigh only a quarter of a pound. Why would things weigh only a quarter as much as they do at the surface of the earth if we took them 4,000 miles out into space? The reason is this: All objects have a natural attraction for all other objects; this is called gravitational attraction. But this power of attraction between two objects gets weaker as they get farther apart. When the butter was at the surface of the earth, it was 4,000 miles from the center. When we took the butter 4,000 miles out, it was 8,000 from the center, which is twice the distance. If you double the distance between two objects, their gravitational attraction decreases two times two. If you treble the distance, it gets nine times weaker (three times three) and so on. So this is one of the first things we need to remember: that the weight of an object in space is not the same as its weight on the surface of the earth. What about the weight of our pound of butter on the surface of the moon? At the distance the pull of the earth is about 4,000 times smaller than it is here on the surface, so we can forget all about the earth-pull on our butter. On the other hand, on the moon there will be an attraction between the butter and the moon: but the butter will weigh only about one-sixth as much as it does on the earth. This is because the moon is so much smaller than the earth. The amount of gravitational pull that a body produces depends on the amount of material in it. A packet of butter has a gravitational pull of its own; but this is very small in relation to the pull of something as large as the moon, or the earth, or the sun.

单选题Who is Dr. Seuss? While many children and adults have enjoyed books by Dr. Seuss, very few actually know anything about Dr. Seuss himself. Dr. Seuss was born in 1904 and was given the name Theodor Seuss Geisel. He grew up in Springfield, Massachusetts and left town as a young man to attend Dartmouth College in New Hampshire. In college, he wrote for the school newspaper. Geisel created the name Dr. Seuss, a penname he would continue to write under for the rest of his life. Seuss first entered college with the idea that he would become a professor, but a classmate who saw him sketching thought he should become an artist. He soon pursued his passion for drawing. After college, he got a job working as a cartoonist for a newspaper. However. once the United States became involved in World War II, Seuss wanted to use his talent to help in the war effort. He worked for the Army making different types of war movies and animated films that were used to train soldiers. Publishers who saw his work during the war wanted Seuss to illustrate a children's book. The war experience, along with his experience as a journalist, led to his desire to write and illustrate his own children books. Dr. Seuss had a slow and difficult start as an author. His first book almost did not get published. However, after many months of being turned down his persistence paid off. Seuss soon signed with a new publisher. This small success was enough to keep Dr. Seuss writing and illustrating. While writing, he often put on silly hats to help to reduce the stress of finishing a story. Shoaly after his first work was published, Dr. Seuss wrote and published The Cat in the Hat, the book that made him famous. For years afterwards, Dr. Seuss continued to write and illustrate many books in his own unique style, which was very different than other authors. He won many awards for his books throughout his writing career, and many were adapted for television and movies. The name, Dr. Seuss, became very popular in children's literature. Though Theodor Seuss Geisel, also known as Dr. Seuss, passed away at the age of 87 in 1991 ,his books and illustrations continue to live on.

单选题The Difference between Man and Computer What makes people different from computer programs? What is the missing element that our theories don't yet (51) for? The answer is simple: People read newspaper stories for a reason: to learn more about (52) they are interested in. Computers, on the other hand, don't. In fact, computers don't (53) have interests; there is nothing in particular that they are trying to find out when they read. If a computer (54) is to be a model of story understanding, it should also read for a "purpose". Of course, people have several goals that do not make (55) to attribute to computers. One might read a restaurant guide (56) order to satisfy hunger or entertainment goals, or to (57) a good place to go for a business lunch. Computers do not get hungry, and computers do not have business lunches. However, these physiological and social goals give (58) to several intellectual or cognitive goals. A goal to satisfy hunger gives rise to goals to find (59) about the name of a restaurant which (60) the desired type of food, how expensive the restaurant is, the location of the restaurant, etc. These are goals to (61) information or knowledge, what we are calling (62) goals. These goals can be held by computers too; a computer (63) "want" to find out the location of a restaurant, and read a guide in order to do so (64) the same way as a person might. While such a goal would not (65) out of hunger in the case of the computer, it might well arise out of the "goal" to learn more about restaurants.

单选题Deport them or not In a country that defines itself by ideals, not by shared blood, who should be allowed to come, work and live here? In the wake of the Sept. 11 attacks these questions have never seemed more pressing. On Dec. 11, 2001, as part of the effort to increase homeland security, federal and local authorities in 14 states staged "Operation Safe Travel" -raids on airports to arrest employees with false identification (身份证明). In Salt Lake City there were 69 arrests. But those captured were anything but terrorists, most of them illegal immigrants from Central or South America. Authorities said the undocumented workers" illegal status made them open to blackmail(讹诈)by terrorists. Many immigrants in Salt Lake City were angered by the arrests and said they felt as if they were being treated like disposable goods. Mayor Anderson said those feelings were justified to a certain extent, "We"re saying we want you to work in these places, we"re going to look the other way in terms of what our laws are, and then when it"s convenient for us, or when we can try to make a point in terms of national security, especially after Sept. 11, then you"re disposable. There are whole families being uprooted for all of the wrong reasons," Anderson said. If Sept. 11 had never happened, the airport workers would not have been arrested and could have gone oil quietly living in America, probably indefinitely. Ana Castro, a manager at a Ben & Jerry"s ice cream shop at the airport, had been working 10 years with the same false Social Security card when she was arrested in the December airport raid. Now she and her family are living under the threat of deportation (驱逐出境). Castro"s case is currently waiting to be settled. While she awaits the outcome, the government has granted her permission to work here and she has returned to her job at Ben & Jerry"s.

Anyone who wanted to change something would get a list of signatures from people who agreed to the idea and either send them to the government or deliver them personally to the Prime Minister's house in London. They are always accepted at the door by one of the PM's officials. What happens then? Nothing much, usually. But petitions have always been thought of as a useful way for those who govern to find out what the people really think. That's why the UK government launched its "e-petition" site in November 2006. Instead of physically collecting signatures, all anyone with an idea has to do now is to make a proposal on the government website, and anyone who supports the idea is free to add his or her signature. The petitions soon started to flow in. The idea was for the British people to express their constructive ideas. Many chose instead to express their sense of humor. One petitioner called on Tony Blair to "stop the Deputy Prime Minister eating so much". Another wanted to expel (驱逐) Scotland from the United Kingdom because Scottish football fans never support England in the World Cup. Other petitioners called on the Prime Minister to abolish the monarchy. Some wanted to give it more power. Some wanted to oppose the United States. Others wanted to leave the European Union. Some wanted to send more troops to Iraq and others wanted them all brought home. Some wanted to adopt the euro (欧元). Others wanted to keep the pound. Yet if some petitions are not serious, others present a direct challenge to government policy. A petition calling on the government to drop plans to charge drivers for using roads has already drawn around 1.8 million signatures. In response to that, a rival petition has been posted in support of road pricing. And that is also rapidly growing. There are about 60 million people in Britain, so it is understandable that the government wants to find out what people are thinking. But the problem with the e-petition site seems to be that the British people have about 70 million opinions, and want the Prime Minister to hear all of them. Perhaps he could start a petition asking everyone to just shut up for a while.

单选题Bees and Color On our table in the garden we put a blue card, and all around this blue card we put a number of different gray cards. These gray cards are of all possible shades of gray land include white and black. On each card a watch-glass is placed. The watch-glass on the blue card has some syrup (果汁) in it; all the others are empty. After a short time bees find the syrup, and they come for it again and again. Then, after some hours, we take away the watch-glass of syrup which was on the blue card and put an empty one in its place. Now what do the bees do? They still go straight to the blue card, although there is no syrup them. They do not go to any of the gray cards, in spite of the fact that one of the gray cards is of exacfiy the same brightness as the blue card. Thus the bees do not mistake any shade of gray for blue. In his way we have proved that they do really see blue as a color. We can find out in just the same way what other colors bees can see. It turns out that bees can see various colors, but these insects differ from us as regards their color-sense in two very interesting ways. Suppose we train bees to come to a red card, and, having done so, we put the red card on the table in the garden among the set of different gray cards. This time we find that the bees mistake red for dark gray or black. They cannot distinguish between them. This means that red is not a color at all for bees; for them it is just dark gray or black. That is one strange fact; here is another. A rainbow is red on one edge, violet on the other. Outside the violet of the rainbow there is another color which we cannot see at all. This color beyond the violet, invisible to us, is called the ultra-violet. Although it is invisible, we know that the ultra-violet is there because it affects a photographic plate. Now, although we are unable to see ultra-violet light, bees can do so; for them ultra-violet is a color. Thus bees see a color which we cannot even imagine. This has been found out by training bees to come for syrup to various parts of a spectrum, or artificial rainbow, thrown by a prism on a table in a dark room. In such an experiment the insects can be taught to fly to the ultra-violet, which for us is just darkness.
