时间状语从句中一般现在时表将来

时间状语从句的用法
时间状语从句中的一般现在时表将来和一般过去时表过去将来,这种说法是不是一旦看到时间状语从句中有一般现在或者一般过去时,就通通把他们理解为将来时和过去将来时?

Answer 1

这是一种不严谨的说法.我们通常说,在时间状语从句中,如果主句是一般将来时,那么从句就要求用一般现在时,有些老师把它总结为叫“主将从先”.如：
I will tell him the good news as soon as he comes back.
如果从句中的动词是一般过去时,可能有以下两种情况：
1.He said that he would tell him the good news as soon as he came back.这种情况就是你所说的过去将来时.
2.I told him the good news as soon as he came back.而这句只是一个单纯的过去时的句子.
