In the north of Scotland there is a lake called Loch Ness. It is the biggest lake in Britain. It is over thirty kilometres long and in places nearly 300 meters deep. It is cold and dark and not many people went there until after 1930. Then a road was made around the lake. Holiday makers began to use the road, and this was when the stories began.
Someone said that he had seen a monster in the lake. He said it was twelve meters long. It had a long neck and a small head. Then someone else said he had seen it. Others said the same thing and in 1933 a London doctor took a photo. It looked like a monster with a long neck and a thick body but the photo was not dear. The newspapers printed the picture and called it the Loch Ness monster, or "Nessie".
Then the argument began. Some people, however, were certain there was something living in the lake. Others said there was nothing there.
In 1961, a lot of people joined together to make a real effort to see and photograph the monster if there was one! Several times people thought they saw something but after ten years there was still no real proof.
Later underwater television cameras were used, but no one found any real proof. However, they did find something interesting: a huge underwater cave. It was big enough to be home of a monster, but of course, this was not a proof.
In 1975, however, some American scientists formed a search group. They used an underwater camera. It took pictures every seventy seconds. Some of the pictures seemed to show a red-brown creature. Its body was about four meters long and had a very ugly head on the end of a four meter neck. Many people then began to believe in the monster. But even today we can not be certain.

Far from the land of Antarctica, 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 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 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?

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 “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
A. sugarB. ice
C. bloodD. molecule

Doctors say anger can be an very harmful emotion unless you learn how to deal with it. They warn that angry feelings can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, losing control of themselves. But other people repress their anger. They cannot or will not express it.
For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain gives off the same hormones(激素)that are produced during tense situations. They speed the heart rate, raise blood pressure, or sugar into the blood and narrow the blood vessels(脉管)to the interstices(空隙). In general, the person feels excited and ready to act.
Doctors said that repressing these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger repeatedly and violently did become, in fact, more and not less angry.
They said this,too,can cause medical problems.
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, and then decide if the cause is serious. If it is, they say: “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably. ”
