20.Find-found-found PhraseLanguage points1. Scientists think that there has been life on the earth for hundreds of millions of years.
科学家们认为地球上的生命已经有上亿年的历史。hundred前加基数词，表示“一百、二百、三百……”，hundred要用单数形式；hundred与of连用表示“数百”时，hundred要用复数形式，即hundreds of。例如：
There are eight hundred students in our school.
There are hundreds of people in the park.thousand, million, billion和hundred的用法相同。no one表示“没有人”，作主语时，谓语动词常用单数形式。如：none 指三个或三个以上的人或物中“没有一个”，其后常接“of + 名词 / 代词”，后面动词单复数形式均可。二. 下列各句中均有一处错误，请指出并改正。
