 同位语:   I have no idea when he will return. 

  我不知道他什么时候回来。

形容词宾语: I'm not sure why she refused their invitation.

  我尚不能肯定她为什么拒绝他们的邀请。

介词宾语:  That depends on where we shall go.

  那取决于我们去哪儿。

2)Wh-从句作主语也常用先行词it做形式主语,而将wh-从句置于句末。例如:

 It is not yet decided who will do that job. 

还没决定谁做这项工作。

 It remains unknown when they are going to get married. 

  他们何时结婚依然不明。

IV. if, whether引导的名词从句

1)yes-no型疑问从句

  从属连词if, whether引导的名词从句是由一般疑问句或选择疑问转化而来的,因此也分别被称为yes-no型疑问句从句和选择型疑问从句,其功能和wh-从句的功能相同。例如:

  主语:Whether the plan is feasible remains to be proved.

  这一计划是否可行还有等证实。

  宾语:Let us know whether / if you can finish the article before Friday.

  请让我们知道你是否能在星期五以前把文章写完。

  表语:The point is whether we should lend him the money.

  问题在于我们是否应该借钱给他。

同位语: They are investigating the question whether the man is trustworthy. 

  他们调查他是否值得信赖。

  形容词宾语: She's doubtful whether we shall be able to come.

  她怀疑我们是否能够前来。

介词宾语: I worry about whether he can pass through the crisis of his illness.

  我担心他是否能度过疾病的危险期。

2)选择性疑问从句

  选择性疑问从句由关联词if/whether...or或whethe...or not构成。例如:

  Please tell me whether / if they are Swedish or Danish.

  请告诉我他们是瑞典人还是丹麦人。

  I don't care whether you like the plan or not.

  我不在乎你是否喜欢该计划。

V. 否定转移

1)将think, believe, suppose, expect, fancy, imagine等动词后面宾语从句的否定词转移到主句中,即主句的谓语动词用否定式,而从句的谓语动词用肯定式。例如:

  I don't think I know you.  我想我并不认识你。

  I don' t believe he will come.  我相信他不回来。

注意:若谓语动词为hope,宾语从句中的否定词不能转移。例如:

  I hope you weren't ill. 我想你没有生病吧。

2)将seem, appear 等后的从句的否定转移到前面。例如:

  It doesn't seem that they know where to go. 看来他们不知道往哪去。

  It doesn't appear that we'll have a sunny day tomorrow. 看来我们明天不会碰上好天气。

3)有时将动名词,介词短语或整个从句的否定转变为对谓语动词的否定。例如:
