Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you"re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there"s going to be a need for orbital accommodation---or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel------private rooms, meals, bars. But they"ll also offer two unique experiences: impressive views----of Earth and space---and the endless entertainment of living in zero gravity---including sports and other activities that make use of this. The hotels themselves will vary greatly----from being quite simple in the early days to huge luxury structure at a later date. It"s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven"t expected launch costs to come down far enough to make them possible. Lots of people who"ve been to space have described vividly what it"s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don"t need to sleep much living in zero gravity, so you"ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below. Of course all good things have come to an end. Unfortunately, And so after a few days you"ll find yourself heading back enough you"ll be much more expert at exercising in zero gravity than you were when you arrived. You"ll be thinking how soon you can save up enough to get back up again---or maybe you should change jobs to get to work in an orbiting hotel. |

People who have lost the ability to understand or use words due to brain damage are called aphasics (失语 症患者). Such patients can be extremely good at something else. From the changing expressions on speakers" faces and the tones of their voices, they can tell lies from truths. Doctors studying the human brain have given a number of examples of this amazing power of aphasics. Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage. Recently, scientists carried out tests to see if all that was said about aphasics was true. They studied a mixed group of people. Some were normal; others were aphasics. It was proved that the aphasics were far ahead of the normal people in recognizing false speeches-in most cases, the normal people were fooled by words, but the aphasics were not. Some years ago, Dr. Oliver Sacks wrote in his book about his experiences with aphasics. He mentioned a particular case in a hospital. Some aphasics were watching the president giving a speech on TV. Since the president had been an actor earlier, making a good speech was no problem for him. He was trying to put his feelings into every word of his speech. But his way of speaking had the opposite effect on the patients. They didn"t seem to believe him. Instead, they burst into laughter. The aphasics knew that the president did not mean a word of what he was saying. He was lying! Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words. However, according to Dr. Sacks, they are more gifted than normal people. Normal people may get carried away by words. Aphasics seem to understand human expressions better, though they cannot understand words. |
1. What is so surprising about aphasics? |
A. They can fool other people. B. They can find out the hidden drugs. C. They can understand language better. D. They can tell whether people are lying. |
2. How did the scientists study aphasics? |
A. By asking them to watch TV together. B. By organizing them into acting groups. C. By comparing them with normal people. D. By giving them chances to speak on TV. |
3. What do we learn from this text? |
A. What ones says reflects how one feels. B. Aphasics have richer feelings than others. C. Normal people often tell lies in their speeches. D. People poor at one thing can be good at another. |

Tom was one of the brightest boys in the year, with supportive parents. But when he was 15 he suddenly stopped trying. He left school at 16 with only two scores for secondary school subjects. One of the reasons that made it cool for him not to care was the power of his peer (同龄人) group. The lack of right male (男性的) role models in many of their lives - at home and particularly in the school environment (环境)-means that their peers are the only people they have to judge themselves against. They don"t see men succeeding in society so it doesn"t occur to them that they could make something of themselves. Without male teachers as a role model, the effect of peer actions and street culture (文化) is all- powerful. Boys want to be part of a club. However, schools can provide the environment for change, and provide the right role models for them. Teachers need to be trained to stop that but not in front of a child"s peers. You have to do it one to one, because that is when you see the real child. It"s pointless sending a child home if he or she has done wrong. They see it as a welcome day off to watch television or play computer games. Instead, schools should have a special unit where a child who has done wrong goes for the day and gets advice about his problems - somewhere he can work away from his peers and go home after the other children. |
1. Why did Tom give up studying? |
A. He disliked his teachers. B. His parents no longer supported him. C. It"s cool for boys of his age not to care about studies. D. There were too many subjects in his secondary school. |
2. What seems to have a bad effect on students like Tom? |
A. Peer groups. B. A special unit. C. The student judges. D. The home environment. |
3. What should schools do to help the problem schoolboys? |
A. Wait for their change patiently. B. Train leaders of their peer groups. C. Stop the development of street culture. D. Give them lessons in a separate area. |
4. A teacher"s work is most effective with a schoolboy when he _____. |
A. is with the boy alone B. teaches the boy a lesson C. sends the boy home as punishment D. works together with another teacher |

Far from the land of Antarctica (南极洲), a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod. For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish"s blood and measured its freezing point. The fish were taken from seawater that had a temperature of-1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to-2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture. The scientists" next research job was clear: Find out what in the fish"s blood kept it from freezing. Their search led to some really strange thing made up of a protein (蛋白质) never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point. Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content. It is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP. |
1. What is the text mainly about? |
A. The terrible conditions in the Antarctic. B. A special fish living in freezing waters. C. The ice shelf around Antarctica. D. Protection of the Antarctic cod. |
2. Why can the Antarctic cod live at the freezing temperature? |
A. The seawater has a temperature of-1.88℃. B. It loves to live in the ice-salt mixture. C. A special protein keeps it from freezing. D. Its blood has a temperature lower than-2.05℃. |
3. What does the underlined word "it" in Paragraph 5 refer to? |
A. A type of ice-salt mixture. B. A newly found protein. C. Fish blood. D. Sugar molecule. |
4. What does "glycol-" in the underlined word "glycoprotein" in the last paragraph mean? |
A. sugar B. ice C. blood D. molecule |

The African elephant, the largest land animal remaining on earth, is of great importance to African ecosystem (生态系统). Unlike other animals, the African elephant is to a great extent the builder of its environment. As a big plant-eater, it largely shapes the forest-and-savanna (大草原) surroundings in which it lives, therefore setting the terms of existence for millions of other animals that live in its habitat (栖息地). It is the elephant"s great desire for food that makes it a disturber of the environment and an important builder of its habitat. In its continuous search for the 300 pounds of plants it must have every day, it kills small trees and underbushes, and pulls branches off big trees. This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas. In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters. Take the rain forests for example. In their natural state, the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor. By pulling down trees and eating plants, elephants make open spaces, allowing new plants to grow on the forest floor. In such situations, the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well. What worries scientists now is that the African elephant has become an endangered species. If the elephant disappears, scientists say, many other animals will also disappear from vast areas of forest and savanna, greatly changing and worsening the whole ecosystem. |

Throughout the history of the arts, the nature of creativity has remained constant to artists. No matter what objects they select, artists are to bring forth new forces and forms that cause change-to find poetry where no one has ever seen or experienced it before. Landscape (风景) is another unchanging element of art. It can be found from ancient times through the 17th-century Dutch painters to the 19th-century romanticists and impressionists. In the 1970s Alfred Leslie, one of the new American realists, continued this practice. Leslie sought out the same place where Thomas Cole, a romanticist, had produced paintings of the same scene a century and a half before. Unlike Cole who insists on a feeling of loneliness and the idea of finding peace in nature, Leslie paints what he actually sees. In his paintings, there is no particular change in emotion, and he includes ordinary things like the highway in the background. He also takes advantage of the latest developments of color photography (摄影术) to help both the eye and the memory when he improves his painting back in his workroom. Besides, all art begs the age-old question: What is real? Each generation of artists has shown their understanding of reality in one form or another. The impressionists saw reality in brief emotional effects, the realists in everyday subjects and in forest scenes, and the Cro-Magnon cave people in their naturalistic drawings of the animals in the ancient forests. To sum up, understanding reality is a necessary struggle for artists of all periods. Over thousands of years the function of the arts has remained relatively constant. Past or present, Eastern or Western, the arts are a basic part of our immediate experience. Many and different are the faces of art, and together they express the basic need and hope of human beings. |
1. The underlined word "poetry" most probably means _____. |
A. an object for artistic creation B. a collection of poems C. an unusual quality D. a natural scene |
2. Leslie"s paintings are extraordinary because _____. |

A. It will not be found in future works of art. B. It does not have a long-lasting standard. C. It is expressed in a fixed artistic form. D. It is lacking in modern works of art. |
4. What does the author suggest about the arts in the last paragraph? |
A. They express people"s curiosity about the past. B. They make people interested in everyday experience. C. They are considered important for variety in form. D. They are regarded as a mirror of the human situation. |
