in case的用法及句型
关于in case的用法及句型,请参考如下:
in case作短语连词,能引导状语从句。就其词义和语法职能来分,可引导两种从句。
其一:in case/just in case引导目的状语从句作“以免,以备,以防”等解。如:
He takes a torch in case it gets dark before he returns.
他带了手电筒,以备天黑以后回家之用。
Please remind me of it again tomorrow in case I forget..
请你明天再提醒我一下,免得我忘记。
其二:in case接条件从句,意为“如果、万一”。如:
In case we fail,we won't lose heart. 万一我们失败,我们决不会失去信心。
Take a hat with you in case the sun is very hot. 倘若太阳很利害你就把帽子戴上。
In case he arrives before I get back,please ask him to wait.
万一我回来前他先到了,请叫他等我。
注意:in case引出的条件从句所表示的意义是"预防某种情况的出现"如果从句说的是一股的假设或条件,则要用if。请比较:
I'll tell him about the matter if I meet him.(不用in case)
Take an umbrella in case it rains.(不用if)
