高考语法:时间或条件状语从句不能用将来时态
由when, as soon as, before, after, as, until等引导的时间状语从句以及由if, unless, as long as, in case等引导的条件状语从句不能直接用将来时态,遇此情况英语习惯上用一般现在时代替一般将来时。如:
趁早动手,免得忘了。
误:Do it before you will forget.
正:Do it before you forget.
我到达那儿后就给你写信。
误:Ill write to you after I will get there.
正:Ill write to you after I get there.
如果他来,请告诉我一声。
误:In case he will come, let me know.
正:In case he comes, let me know.
