9类状语从句的的备考说明

6. 目的状语从句及备考说明

目的状语从句主要由 in order that, so that, in case, for fear从属连词引导。如：

We arrived early so that [in order that] we could get good seats. 我们到得早，以便找到好座位。

I bought the car at once for fear (that) he might change his mind. 我马上买下那辆汽车，以免他变卦。

【备考说明】原则上说以in order that, so that, in case, for fear引导的状语从句都很重要，都不能轻视，尤其是以in case引导的目的状语从句，更要引起特别注意。请再看几个例句：

I don’t let him climb trees in case he tears his trousers.  我不让他爬树，以免撕破裤子。

I always slept by the phone in case he rang during the night. 我总是睡在电话机旁边，惟恐他夜间打电话来。

I’ll keep a seat for you in case you should change your mind. 我给你留一个座位，以防你会改变主意。

注：in case除引导目的状语从句(表示“以防”“以免”)外，还可引导条件状语从句(表示“如果”“万一”)，请不要混淆。
