2019-2020学年人教版高中英语选修8优化教案:Unit 1 Section  Ⅲ  Grammar— 名词性从句(主语从句、宾语从句和表语从句)第3页

  动词后有两个或两个以上的宾语从句时,紧跟动词后的宾语从句可以省去that,其余的宾语从句前的that一般不能省去。

  I believe (that) you have done your best and that things will improve.

  我相信你已经尽全力了,事情会好起来的。(第二个that不能省)

  (3)"doubt+宾语从句"的应用。

  肯定句中用whether或if,否定句和疑问句中用that。

  I doubt whether he can pass the exam.

  我怀疑他是否能够通过此次考试。

  I don't doubt that he can pass the exam.

  我不怀疑他能通过此次考试。

  Do you doubt that he can pass the exam?

  你怀疑他能通过此次考试吗?

  (三)表语从句

  1.表语从句在复合句中作表语,出现在连系动词之后,一般结构为"主语+连系动词+表语从句"。

  The question is whether we can finish the work in time.

  问题是我们是否能及时完成这项工作。

  2.可接表语从句的连系动词有be, look, remain, seem, sound等。

  You look as if you slept badly.

  看你那样子仿佛没睡好觉。

  The fact remains that we are still not advanced enough.

  事实依然是我们还是不够先进。

  [名师点津] (1)表语从句实际上是对主语进行补充说明,从句表达的是主语的内容。

  The fact is that he didn't notice the car until too late.

  事实是他注意到汽车时已经太晚了。

  (2)主句的主语是名词idea, advice, suggestion, order, request, requirement等时,表语从句应用虚拟语气,即谓语动词用"should +动词原形"。

  My suggestion is that we should have a discussion about this matter instead of setting it aside.

  我的建议是我们应当讨论一下这个问题,而不是把它放在一边。
