【题目】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°C 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°C. 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 (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.

C. Fish blood.

D. Sugar molecule.

3What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?

【题目】More than 27,000 people from around the UK set off at dawn from London to begin the cycle route through Surrey to the Sussex coast.

The annual 54-mile ride raises money for the British Heart Foundation(BHF) and is Europe’s largest charity cycling event. Cyclists began the exhausting journey at Clapham Common at 6 a. m. , hoping to reach Brighton seafront within an average of six hours.

Money from today's event will help the charity to continue its vital work through heart research and the development of its care and support services. Among those taking part was BBC Breakfast's resident(居民)Dr Rosemary Leonard and several colleagues.

BHF spokeswoman Gemma Cloke said, “It was quite cold this morning, but everyone set off without any problems.” Those taking part range in age from 14 to those in their 70s. Last year cyclists raised£4. 1 million for the charity, and have raised more than£50 million since the BHF became involved in the event in 1980. The first ride was held in 1976. It is hoped this year's fund raising total could reach£4. 5 million. She added : “We have a lot of people taking part, from the more experienced cyclists to those cycling with friends and family in memory of someone and to raise money through sponsorship.”

“People are always pleased knowing the money is going to a good cause. There is so much support along the route, with local residents watching the ride.

“One of the highlights for participants(参加者)is coming along the seafront while people are clapping, which can/span> really help when they've been in the saddle (自行车车座) for a long time.

【2 What can we learn from what Gemma Cloke said?

A. Cyclists will receive encouragement from local people.

B. Some people doubt whether the money is properly used.

C. Most of the cyclists are professional.

D. Local people have little interest in cycling events.

【3 The local residents’ attitude towards the ride is .

A. doubtful B. unconcerned

C. supportive D. indifferent

【4 What is the text mainly about?

A. Cyclists have raised over£50 million for the BHF.

B. More than 27,000 people like travelling by bike in the UK.

C. Charity cycling event wins support from local people.

D. More than 27,000 people in the UK join in the charity bike ride.
