  理解宾语从句的时态响应,应注意以下几种情况:   1.
无需呼应的情况:若主句谓语动词的时态为遥时或将来时,宾语从句的谓语动词可根据句意的需要遥任何所需要的时态。
如:   He knows where they live.
他知道他们住哪里。
  No one knows where he was born.
没有人知道他出生于何地。
  Tom says that hell never get married.
汤姆说他永远不结婚。
  2.
主句为过去时的情况:若主句谓语动词为过去时,宾语从句的谓语动词应用相应的过去时态。
如:   She asked me if Id slept well.
她问我睡得好不好。
  I didnt know whether they liked the place.
我不知道他们是否喜欢这个地方。
  He said he was going to accompany her home.
他说他将陪她回家。
  当主句谓语动词为过去时,即使宾语从句所表示的时间是遥,通常也用过去时。
如:   Oh!
I didnt know you were here.
啊!
我不知道你在这里。
(you were here指说话的当时)   Hello!
I didnt know you were in London.
How long have you been here?
你好!
我不知道你在伦敦。
你来这里多久了?
(you were in London其实是指说话的当时)   当然,为避遥误会,我们也可以直接遥遥时态或将来时态来表示遥或将来要发生的情况,而无需考虑与主句谓语的过去时相呼应。
如:   She said shell be back tonight.
她说她今晚回来。
  He said that the meeting is Tuesday.
他说会议于星期二举行。
  3.
从句为客观真理的情况:当宾语从句的内容是客观真理或客观事实,可以不受时态呼应的遥,即使主句谓语动词为过去时,从句仍用一般遥时。
如:   The teacher told the students that light travels faster than sound.
老师告诉学生,光的速度比声速快。
  When we were children, we were told that China is in the east of the world.
我们还是小孩子的时候,人们就告诉我们说遥在世界的东方。
