Passage Two

听力原文

    (19) 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. (20) 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. (21) 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.

20. Why do local people in Seattle seldom carry an umbrella?

解析：B。录音中间部分提到，西雅图很少有当地人随身携带雨伞，因为下雨的时候，一般是很小的雨（a very light rain），并不会造成什么麻烦，故正确答案为B。录音中没有提到过西雅图的人大部分时间在开车，A项为无中生有，故错误。录音中虽然提到西雅图下雨的时候，一般是下很小的雨，并不会造成什么麻烦，但这不等同于当地人习惯了下雨，故C项排除。录音中也没有提及D项关键词at night，故D项为无中生有，排除。
