他害怕在结冰的石块上滑倒。
对过去的动作表示担心时用should+完成式:
She began to be worried lest he should have met with some accident.
她开始担心他出了什么事。
2 lest也可用于目的从句,表示 for fear that(惟恐):
He dared not spend the money lest someone should ask where he had got it.
他不敢花这笔钱,怕有人问他钱是从哪儿来的。
如上所示这是一种书面形式。
在这种情况下 in case较 lest更常用,后面可跟 should或一般现在时或一般过去时:
in case someone should ask/someone asked
惟恐万一有人问起
D should 有时用于目的从句以代替 would/could:
He wore a mask so that no one should recognize him.

E 在条件句中用should代替现在时态:
If the pain should return take another of these pills.
疼痛复发时,可再吃一片这些药。
F should 还用于颇为正式的间接命令,这种命令不一定是向对方直接发出的:
He ordered that Tom should leave the house.
