　　听力原文及谜底

　　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’?
