I don’t know where he will go tomorrow. 我不知道他明天去哪兒。(賓語從句)
I’ll tell him when you will ring again. 我告訴他你什么時候再來電話。(賓語從句)
比較:I’ll tell him when you ring again.你再打電話時我告訴他。(狀語從句)
(8)在make sure, make certain, see (to it) 后的that從句中,謂語動詞用一般現(xiàn)在時代替將來時,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)
3.完成時是時態(tài)測試的重點,注意與完成時連用的句型和時間狀語:
(1)by/between/up to/till +過去時間、since、by the time/when +表示過去發(fā)生情況的從句,主句用過去完成時。如:
We had just had our breakfast when an old man came to the door.
Between 1897 and 1919 at least 29 motion pictures in which artificial beings were portrayed had been produced.
(表示1919年時已發(fā)生的情況)
(2)by +將來時間、by the time/ when +謂語動詞是一般現(xiàn)在時的從句,主句用將來完成時。如:
By the time you arrive in London, we will have stayed in Europe for two weeks.
I hope her health will have improved greatly by the time we come back next year.
(3)by now、since +過去時間、in/during/for/over/the past/last few(或具體數(shù)字)years/days/months,主句用現(xiàn)在完成時, 但在it is +具體時間since/before這一句型中,主句更多的時候不用完成時。如:
The changes that howe taken place place in air travel during the last sixty years would have seemed completely impossible to even the most brilliant scientists at the turn of the 19th century.
It is four years since John left school.
(4)在It is the +序數(shù)詞/形容詞最高級+that的定語從句中,謂語動詞常用現(xiàn)在完成時。如:
It isn’t the first time that I have found myself in an embarrassing situation.
