如 :What I saw was beyond any verbal description.That his hair was turning grey worried him a bit.Why the company denied the contract is still unknown.When and where the government will build a city square is under discussion.It is pretty annoying that a small part of the machine is missing.It remains to be seen whether the new novel will be well received.Tips: 主语从句的 that 绝对不能省去。

(1).如果主句的谓语动词是一般现在时或一般将来时,宾语从句用它本身的时态。
I hear he will come back in an hour.(2).如果主句的谓语动词是一般过去时,宾语从句则用相应的过去时态。

The newspapers have it that some Japanese firms have gone bankrupt.报纸说有几家日本公司已破产这类动词还有:have(表明,坚持说),take(认为),hide(隐瞒),love ,like,dislike, hate, enjoy ii) 在主谓宾结构中, 如果谓语动词是短语动词,即动词+介词,一般不能that接从句。

I will answer for it that Lao Ma will accomplish the task.我担保老马能完成这项任务Look to it that you make no more similar mistakes.注意今后你不再犯类似的错误了I am counting on it that you will come.我期待着你的到来这类动词还有:depend on, see to etc.iii)某些固定搭配之后如果接that宾语从句,也必须使用作形式宾语it.We owe it to you that there wasn’t a serious accident.这次事故没造成严重的后果全靠你I didn’t send you an invitation, as I took it for granted that you would be coming.因为我认为你当然会来,所以没有给你发请柬三1 否定的转移当主句的谓语动词是think, believe, suppose, expect, imagine等表示看法的动词时,宾语从句中谓语动词的否定式,习惯上前移到主句的谓语动词上.I don’t think that he will be back until nine.2 复杂疑问句/双重疑问句特殊疑问词+do you think/ believe/ suppose/imagine etc+其它部分(陈述句语序)?Who do you guess that girl in red is?Who do you imagine will speak at the meeting tomorrow?3 ----Will they be ready tomorrow?----Yes, I think so. (Yes, I think that they will be ready tomorrow)so 用来替代某一些动词(think, believe, suppose, imagine, hope etc) 后面的that从句.----Will they attend the meeting next month? ----No, I don’t believe so (I believe not)在替代否定概念,既可以用so,也可以用not.但是:在hope和be afraid后在替代否定概念只能是not,不能是so.----Do you think we’ll have bad weather? ----I hope not.----Have you got a work permit? ----I’m afraid not.第三节表语从句含有表语从句的复合句,其主句的主语常常用fact, idea, opinion, problem, question, reason, result或者由what引起的主语从句。
引导表语从句连接代词或者连接副词除常用that以外,who, which, what, whether, when, where, why, how, because, as, as if/as though等。
如:The chance is that one smoker in four will die from smoking.What we want to know is whether your products came up to the standardShenzhen is no longer what it used to be.This is how they overcame the difficulties.It sounds as if/though somebody was knocking at the door.注意:先说结果,后说原因,用This/That is because…先说原因,后说结果,用That/This is why…当主语是reason时,引导表语从句的连接词只能用that ,如He is absent. This is because he is ill.// He is ill. That is why he is absent.// The reason why he is absent is that he is ill. 第四节同位语从句1 先行词与连接代词或者连接副词的选择常见的可以跟同位语从句的名词有:fact, news, hope, belief, truth, message, word, idea, doubt, question, problem, reason, order, suggestion, 等。
引导同位语从句连接代词或者连接副词除常用that以外,who, which, what, whether, when, where, why, how等。
如:I have no idea whether he can manage to do that himself.I have no idea where he spent the night.The question how the students could improve their spoken English is very important2 同位语从句与定语从句的区别He made a decision that surprised all of us.He has made a decision that he will set up a new factory.同位语从句说明名词的具体内容。
that和whether只起连接作用,不充当任何成分,不能省略,也不能用which或if代替;其他的连接词在同位于从句中作句子成分,但不是指代前面的名词,而是有自身疑问意思。
