  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。
