重点句式
1. It took her a long time to do her hair and make-up...（教材P3）做头发和化妆用了她很长时间……
【句式剖析】“It takes sb + 一段时间 + to do sth”结构，表示“做某事花费某人一段时间”，其中It是形式主语，to do sth是真正的主语。该句型可用于多种时态，主语除用it作形式主语外，还可以是指人或事的名词。

我每天从家到学校需要十分钟。
The work took me three hours to finish.

那就是为什么他们决定改吃野炊午餐。
The reason why he was absent was that he had a high fever.
他缺席的原因是他发高烧了。
表语从句中的why, because以及that可根据“直译法”去判断，也就是语境当中翻译成“是因为……”就用because，翻译成“那就是为什么……”就用why，而如果翻译成“是……”，在表语从句中多用that。
