题目内容
1.He doesn't tell me when he_______.I'll telephone you as soon as he______.( )| A. | will come; comes | B. | will come; will come | ||
| C. | comes; will come | D. | comes; comes |
分析 他没有告诉我他什么时候来,他一来我就给你打电话.
解答 答案:A.第一个when引导的是宾语从句,主句是一般现在时,从句时态不受限制,表达的是将来的动作故用一般将来时will+动词原形,as soon as一…就,引导的时间状语从句,遵循主将从现的规则,从句主语he,故comes,故答案是A.
点评 as soon as 的用法一般是两种情况:
1、指未发生的动作,规律是:主句一般将来时,从句用一般现在时代替一般将来时
如:I will tell him the news as soon as he comes back.
注:有时,为了特意表达刚刚完成某事就如何如何,需要用现在完成时.
如:I will go with you as soon as I have washed my face.
2、指紧接着发生的两个短动作,主从句都用一般过去时
如 He took out his English books as soon as he sat down
