  用来充作宾语的句子叫做宾语从句。
如:   He asked what you were doing last night.
他问你昨天夜晚在干什么。

  在宾语从句中须注意:   1.
that 在口语中常被省略,但在正式的文体中,不能省;并且它一般不能引导介词的宾语从句,但可引导except, but, in 等少数介词的宾语从句。
如:   I didnt know (that) he was Li Lei.
我不知道他就是李蕾。
  I will do anything I can to help you except that Im ill.
只要我身体舒服,我愿做任何事情来帮助你。
  2.
宾语从句之后带有补足语成分时,一般须用it作形式宾语,把宾语从句放到句末,此时的that不能省。
如:   The boy has made it clear that they cant play with his toys.
那个男孩已清楚的表明他们不能玩弄他的玩具。
  3.
动词advise, ask, demand, desire, insist(坚决主张), order, propose, request, suggest(建议)等代的宾语从句须用虚拟语气,即:(should) do的形式。
  He asked that we (should) get there before nine oclock.

  The teacher advised us that we (should) not waste our time.
老师劝告我们不要浪费时间了。
  4.
宾语从句的时态与主句的时态须呼应。
  1)当主句谓语动词的时态是遥时或将来时,从句的谓语动词可用任何所需要的时态表示。
如:   He always says that he is our good friend.
他总是说他是我们的好朋友。
  When the teacher knows what we have done, he will say that we have done a good deed.
当老师知道我们所干的事情时,他会说我们做了一件好事。
  2)当主句谓语动词的时态为过去时,从句的谓语动词须用响应的过去时。
如:   He didnt tell us he came from Shanghai.
他没有告诉我们他来自上海。
  He said he had read the book.
他说他读过这本书。
  3)但当从句的内容是客观真理或客观事实,而不受时间的遥时,即使主句谓语动词为过去时,从句仍用一般遥时。
如   Chairman Mao said that all the imperialists are paper tigers.
毛遥说一切帝国主义者都是纸老虎。
  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。
