主旨大意是文章的核心,包括对title, main idea或 者main purpose的判断选择,也会以“mainly tell about” 一类的形式出现。做这类题时,仔细阅读文章或段落 的首尾句是关键。多采用浏览法,一般不需逐句细读, 只选读文章的首段、尾段,或每段的首句和尾句,重 点搜索主题线索和主题信息。但是当讲述一个故事时, 则要抓住每段文字的关键句。
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn't be a builtin device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操 作杆)on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.
