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.
68. 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.
69. 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℃.
70. 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.
71. What does “glycol-” in the underlined word “glycoprotein” in the last paragraph mean?
A. sugar B. ice C. blood D. Molecule

It’s not easy being a teenager（13至19岁青少年）—nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you you’ll still be there for him when he needs you.
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll clam up. Instead, let him attempt to solve things by himself. At the same time, remind him that you’re always there for him if he seeks advice or help. Show respect for your teenager’s privacy（隐私）. Never read his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation（节制）. Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part–time job.

Heroes of Our Time
A good heart
Dikembe Mutombo grew up in Africa among great poverty and disease. He came to Georgetown University on a scholarship(奖学金) to study medicine — but Coach(教练) John Thompson got a look at Dikembe and had a different idea. Dikembe became a star in the NBA, and a citizen of the United States. But he never forgot the land of his birth, or the duty to share his fortune with others. He built a new hospital in his old hometown in the Congo. A friend has said of this good-hearted man: “Mutombo believes that God has given him this chance to do great things.”
Success and kindness
After her daughter was born, Julie Aigner-Clark searched for ways to share her love of music and art with her child. So she borrowed some equipment, and began filming children’s videos(录像) in her own house. The Baby Einstein Company was born, and in just five years her business grew to more than $20 million in sales. And she is using her success to help others — producing child safety videos with John Walsh of the National Center for Missing and Exploited Children. Julie says of her new program: “I believe it’s the most important thing that I have ever done. I believe that children have the right to live in a world that is safe.”
Bravery and courage
A few weeks ago, Wesley Autrey was waiting at a Harlem subway station with his two little girls when he saw a man fall into the path of a train. With seconds to act, Wesley jumped onto the tracks, pulled the man into the space between the rails(铁轨), and held him as the train passed right above their heads. He insists he’s not a hero. He says: “We have got to show each other some love.”
60. What was Mutombo praised for?

第三部分阅读理解（共20小题；每小题1分，满分20分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
I travel a lot, and I find out different “styles”(风格) of directions every time I ask “How can I get to the post office?”
Foreign tourists are often confused(困惑) in Japan because most streets there don’t have names; in Japan, people use landmarks(地标) in their directions instead of street names. For example, the Japanese will say to travelers, “Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop.”
In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, “Go north two miles. Turn east, and then go another mile.”
People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. “How far away is the post office?” you ask. “Oh,” they answer, “it’s about five minutes from here.” You say, “Yes, but how many miles away is it?” They don’t know.
It’s true that a person doesn’t know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, “Sorry, I have no idea.” But in Yucatan, Mexico, no one answers “I don’t know.” People in Yucatan believe that “I don’t know” is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!

A. describe the place carefully B. show him a map of the place
C. tell him the names of the streets D. refer to recognizable buildings and places
57. What is the place where people measure distance in time?
A. New York. B. Los Angeles. C. Kansas. D. Iowa.
58. People in Yucatan may give a tourist a wrong answer ______.
A. in order to save time B. Los Angeles.
C. so as to be polite D. for fun
59. What can we infer from the text?
A. It’s important for travelers to understand cultural differences.
B. It’s useful for travelers to know how to ask the way properly.
C. People have similar understandings of politeness.
D. New Yorkers are generally friendly to visitors.

As a result of pollution , Lake Erie , on the borders of the USA and Canada, is now without any living things.　　
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organism(生物体 ) to be affected are either plants or plankton. But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.　　
Where do the substances which pollute the water come form? There are two main sources sewage (污水) and industrial waste. As more detergent (洗涤剂 ) is used in the home, so more of it is finally put into our rivers. lakes and seas. Detergents harm water birds dissolving the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous things in it, such as copper and lead(铅 ).　　
So , if we want or stop this pollution , the answer is simple: sewage and industrial waste must be made clean before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.　　
72. Pollution in water is noticed _____. 　　
A. when the first organisms are affected B. when a good many fish and birds die　　
C. when poisonous things are poured into water　　
D. as soon as the balance of nature is destroyed　　
73. The living things die because there is no ____ in the lake or river.　　
A. water B. fish C. poison D. oxygen　　
74. Which of the following is harmful according to the passage? 　　
A. Organisms B. Plants and plankton in the water　　
C. Waste water from cleaning D. Industrial waste made clear before flowing into the water 　　
75.The way to stop water pollution is _______.　　
A. realize the serious situation clearly　　
B. put oxygen into the river　　
C. make the waste material harmless before flowing into the water 　　
D. make special room in the sea for our rubbish
