句型16

　　while引导的从句

　　while除了有“当/在……时候”的意思外(注意：引导的句子谓语动词只能是延续性动词!)，另外的两层意思也是考查的重点：(1)while = although “尽管”、“虽然”，引导让步状语从句;(2)while的意思是“然而;可是”，常用来表达对比关系。

　　[例句]

　　While I admit that the problem is difficult, I don’t think that they can’t be solved.

　　尽管我承认这个问题很难，但是我并不认为无法解决。

　　While I admit his good points, I can see his shortcomings.

　　虽然我承认他的优点，我也能看出他的缺点。

　　where…(地点从句)

　　[注意]where引导地点从句时，可以引导定语从句或是逻辑地点状语从句。当它在定语从句中作地点状语，指代地点时，这时可以用in which, on which, at which, to which, from which等结构代替。但是它引导逻辑地点状语从句时，没有这样用法。

　　[例句]

　　You should put the book where it was. 把书放回原处。

　　what引导的从句

　　what在英语中非常活跃,它可以用来引导主语从句、宾语从句、表语从句，但是不用来引导定语从句。在句子里可以充当主语、宾语、表语、定语，既可以指人，也可以指物。
