编辑老师整理的这篇最新英语六级语法辅导之时态、语态讲解了表达将来时的形式、表达完成时的形式及完成进行时等时态的相关信息,一起来看一下吧!

1.表达将来时的形式:

(1)在时间、条件、让步从句中,一般现在时代替将来时,但要注意区别从句的类型,如:

I’ll tell him when you will ring again. 我告诉他你什么时候再来电话。(宾语从句) 比较:I’ll tell him when you ring again.你再打电话时我告诉他。(状语从句)

(2)在make sure, make certain, see (to it) 后的that从句中,谓语动词用一般现在时代替将来时,如:

See to it that you include in the paper whatever questions they didn’t know the answer to last time.(include 不能用will include或其他形式)

2.完成时是时态测试的重点,注意与完成时连用的句型和时间状语:

(1)by/between/up to/till +过去时间、since、by the time/when +表示过去发生情况的从句,主句用过去完成时。如:

Between 1897 and 1919 at least 29 motion pictures in which artificial beings were portrayed had been produced.

(表示1919年时已发生的情况)

(2)by +将来时间、by the time/ when +谓语动词是一般现在时的从句,主句用将来完成时。如:
