AEAS考试 AEAS英语

动词的时态在英语学习中起着举足轻重的作用,也是AEAS考试语法部分的重点.今天易伯华小编带大家一起来针对某些特殊句式中的时态加以归纳分析，希望能够帮助大家更好的进行AEAS考试的学习和准备。

1.“主将从现”原则

即若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。如：

I’ll give her the telex when she comes.她来时把电传交给她。

I’ll return the book as soon as I have read it.这书一看完我就送还。

He’ll have four years at university after he leaves school.他中学毕业后要上四年大学。

2.since与完成时

since引导时间状语从句时，其主句通常要用现在完成时，有时也用现在完成进行时。如：

She has had another baby since I saw her last.从上次我见到她以来，她又生了一个孩子。

He has grown an inch since I saw him.我上次见到他以后他已长高了一英寸。

注：当主句为“It+be+一段时间”时，则通常用一般现在时代替现在完成时。如：

It’s more than three years now since I saw her last.我们已有三年多没见面了。

3.特定句式的时态

由no sooner...than,hardly[scarcely]…when引出的时间状语从句，其主句通常用过去完成时，从句通常用一般过去时。如：

Hardly had he arrived when she started complaining.他刚到她就抱怨起来。

No sooner had he gone to sleep than the telephone rang.他刚睡着电话铃就响了。

We had no sooner set out than a thunderstorm broke.我们刚出发就下起一阵雷暴。

No sooner had she agreed to marry him than she started to have terrible doubts.她刚同意嫁给他她就开始产生可怕的疑虑。
