关于lest, for fear that, in case的虚拟语气用法

Question

他们的谓语动词是不是 必须要用should+动词原形 ?
貌似这三个中有哪个是可以省略should的 吧?是哪个?
咋就3个答案都不一样= =

Answer 1

一、三种用法 引导目的状语从句 常用虚拟语气 should可以省略。

1、lest sb （should ）do sth.

译文：免得某人应该做某事。

2、for fear that sb （should ）do sth.

译文：担心某人应该做某事。

3、in case sb （should） do sth.

译文：某人应该做某事。

二、for fear that,in case 与lest.

这些从属连词(词组)引导的目的状语从句中谓语动词要用(should+)动词原形，它本身带有否意义，相当于so that...not…或in order that… not…。

二、释义：

1、lest

conj. 唯恐，以免；（引出产生某种情感的原因）唯恐，担心。

2、for fear that

生怕，唯恐；以免；以防万一。

3、 in case

conj. 万一；假使。

Answer 4

lest、for fear that和in case引导的从句用虚拟语气，其谓语部分用“should+动词原形”。
其中，lest和for fear that引导的葱郁，可以省去should，但是in case引导的从句，如果表示虚拟，should一般不可省略！
