Nowadays women appear to have a positive image of themselves as safer drivers than men.

In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. “Women are on average less aggressive and more law abiding (守法的) drivers, which leads to fewer accidents,” the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them upon one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control，which helps prevent rollover accidents.

Auto safety unavoidably matters to Money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website Insweb also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest, advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D.C, where their insurance costs are 16% lower.

“More than 11,900 male drivers died in US traffic accidents in 2009，compared with just under 4,900 women drivers” according to the study. “Based on miles traveled, men died at a rate of 2.5 deaths per 100 million miles traveled, vs.1.7 deaths for women.”

1.According to the study，female drivers ________.

A. are more aggressive while driving

B. are more interested in auto knowledge

C. are more likely to stick to driving laws

D. are more familiar with safety equipment

2.Insurance companies focus on female driver clients probably because they________.

A. cause more accidents on the road

B. pay more money to the insurance companies

C. take the most part of the insurance clients

D. have the lowest amount of money on insurance claims

3.We can infer from the passage that________.

A. men are 3.1 times more likely to get tickets than women

B. all women in the USA pay the same for their auto insurance

C. more female drivers die every year than male drivers

D. women are generally safer drivers than the opposite gender

4.The writer mainly develops paragraphs by________.

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?

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

A. sugarB. ice

C. bloodD. molecule

试题分析: 本文介绍了科学家对于南极洲一种小鱼为什么能够在如此寒冷的情况下还能生存的原因的剖析，原因在于这种鱼的血液里存在的一种蛋白质。

1.B主旨大意题。根据文章主题段第一段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.可知本文讲述的是南极洲的一种小鱼，故B正确。

2.C细节题。根据文章第四段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.可知正是这种蛋白质让这种鱼能够再这么低温的情况下存活。故C正确。

3.B推理题。根据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.可知当这种物质被拿走以后血很快就凝固了，故it就是指前面的protein，故B正确。

4.A推理题。根据Because of its sugar content, it is called a glycoprotein.可知该名词肯定是与sugar有关，故A正确。
