　　Section C
　　Passage 1
　　Single sex education can have enormous benefits for female students. Numerous studies have shown that women who attend single sex schools tend to have stronger self confidence, better study habits and more ambitious career goals than women who attend coeducational schools. Girls who graduate from single sex schools are three times more likely to become engineers than those who attend coeducational schools. The reason is that all girls schools encourage women to enter fields traditionally dominated by men such as science, technology and engineering. In coeducational schools, girls are often expected to succeed only in humanities or the art. Research has also shown that in coeducational settings, teachers are more likely to praise and give in depth responses to boys’ comments in class. In contrast, they might only respond to a girl’s comments with a nod. They are also more likely to encourage boys to work through problems on their own, while they tend to step in and help girls who struggle with a problem.
　　In an all girls setting, girls are more likely to speak up frequently and make significant contributions to class than in a coeducational setting. Girls studying in a single sex setting also earn higher scores on their College Board and advanced placement exams than girls who study in coeducational settings. All girls schools tend to be smaller than coeducational schools, which means teachers would be able to tailor the materials to girl students’ personal learning styles and interest.

　　Passage 2
　　Today I found out that Seattle doesn’t really get that much rain compared with most US cities. In fact, Seattle ranks 44th among major US cities in average annual rainfall. Cities that get more rainfall than Seattle include Huston, Memphis, Nashville, and pretty much every major city on the eastern coast, such as New York, Boston, and Miami.
　　So, why does everyone think of Seattle as a rainy city? The primary root of this misconception lies in that Seattle has a relatively large number of days per year with rainfall compared with New York and Boston, which get an average of about 16% more rain per year than Seattle, but also average between them about 36 fewer days a year of rainfall. So it rains a lot less in Seattle. And the rain is spread out over more days than those cities. This is why few locals in Seattle carry an umbrella generally. When it does rain, it tends to be a very light rain that isn’t troublesome. It almost never really rains as most people think. On top of that, it never really storms in Seattle, either. Seattle gets an average of a mere 7 days a year with thunder.
　　So in short, if you like sunny but not too hot summers, mild winters but with lots of cloudy days, Seattle’s the place to be. Anyway, if you visit Seattle, don’t bring an umbrella. People will look at you, thinking you are funny.
　　Questions 19 21 are based on the passage you have just heard.
　　Q19. What does the speaker find out about Seattle?
　　Q20. Why do local people in Seattle seldom carry an umbrella?
　　Q21. Why does the speaker say ‘Seattle is a good place to be’?

　　答案
　　19. C, it does not rain as much as people think
　　20. A, the rain is usually very light
　　21. B, it has mild weather both in summer and in winnter
　　Passage 3
　　After tough workout or a day full of physical activity, it’s common to find your muscles aching, but where do these pains come from? According to a German professor, the soreness comes from straining your muscles in an uncommon way, for example, jumping on a bicycle for a ride, because you haven’t ridden in a long time. Soreness occurs since your leg muscles aren't used to that movement. When muscles perform an activity they aren’t regularly expose to, the tiny fibers that are inside them are being torn apart. As muscle soreness develops, the body has to work to repair the muscle tears, but this doesn’t happen immediately. First, the body must realize the muscles are damaged. When the body realizes the muscles are hurt, the response is to increase blood flow to the area and increase body heat, damaged cells are then cleaned up and the body sends cells specially designed to break down the large muscle fiber fragments. Healing can take place after this. It takes about a day until these cells make it to your aching muscles. That’s why there is most often a delay associated with muscle soreness. Repair of damaged cells takes about two days, and afterwards the soreness disappears. Unfortunately, there is little that can be down to relieve muscle soreness. Pain relieving creams don’t work, but a hot shower, or warm bath can provide some relief.
　　Questions 22 25 are based on the passage you have just heard.
　　22. What does the German professor say about muscle soreness?
　　23. What happens when muscles are damaged according to the passage?
　　24. How long does it take for damaged cells to heal?
　　25. What does the speaker suggest one do to relieve muscle soreness?

　　23. D, blood flow and body heat increase in the affected area
　　24. A, about two days
　　25. B, have a hot shower
