6、t, which, whom, whose, whatever , whoever, whomever, whichever 等； 关系副词when, where, why, how, however , whenever, wherever 等。可以接表语从句的连系动词由be, look, remain, seem 等。That引导表语从句时，在口语中，问或 可以省略。The trouble is that we are short of money.困难是我们资金短缺。That is why stone walls are used instead of fences around New

11、的。一、考点聚焦1、名词性从句中连接词的运用名词性从句中的连接词有连词that / whether / as if ,连接代词what / who/ which / whose /whatever / whoever / whomever / whichever ,连接副词 where / when / why / how / wherever/ whenever。（1） that的用法。主语从句、表语从句、同位语从句中用that但不能省略。如：That they are good at English is known to us all.The problem is that we don

12、 ' t have enough money.She expressed the hope that they would come to China one day.宾语从句中的连接词that有时可省有时又不可省，在以下几种情况中that不能省略：（A）当that从句和主句谓语动词之间有插入词语或者从句主语之间有插入语时that不可省略；（B）当that从句与另一名词性从句并列作宾语时，that不能省；（C）当that作介词宾语时，that不可省掉。如:He judged that, because he was a child, he did not understand wine

13、Everyone knew what happened and that she was worried.The reason lies in that she works harder than the others do.that从句作主语和宾语时，可以用it来替换成以下几种结构表达(A)It is clear/certain/likely/true/surprising that (B) It is a pity/shame/good idea/no wonder that . (C) It is said/reported/ believed/known/thought/suggest

14、ed that (D) It seems/happens that。如：It happened that I went out last night.It is said that China will win in the World Cup.that和what的区别。that引导名词性从句时，在主从句中不以当任何句子成分，也没有任何含义；而what引导名词 性从句时，在主从句中都要充当一定的句子成分,what可以分解成定语从句中的先行词+关系代词 即常说的先行词+ that。如：It' s shame that he has made such a mistake.Do what

15、he says.同位语从句与定语从句中that的区别。同位语从句中的连词that只起连接作用，在从句中不担当任何句子成分;而定语从句中的关系代 词that在句中做宾语或主语，宾语与先行词有修饰关系。如果句子是同位语从句，就应用连词hat 而不能用which.同位语从句一般放在表具体含义的名词后解释名词的含义或内容，如以下名词： news、fact、suggestion、truth、plan、belief > doubt、 possibility > idea 等，而定语从句只是 对先行词的限定和修饰。如：They expressed the hope that they would

16、 come to visit China again.(同位语从旬The hope she expressed is that they would come to visit China again. (定语从句)（2） whether 和 if 的用法。whether和if在宾语从句中可以互换，但是作介词宾语时连接词一般Whether。如：It all depends on whether they will come back.后面直接跟or not时用whether。如：I didn ' t know whether or not he had arrived in Wuhan

17、.主语从句表语从句中只能用whether。如：Whether the meeting will be put off has not been decided yet.The question is whether they have so much money.whether可以引导同位语从句，用以说明前面的名词的内容,if不能。如：We ought to discuss carefully the question whether we can doit or not.whether常与or连用表示一种选择，if不能这样用；whether也可与动词不定式连用但if不 能。如：The que

18、stion of whether they are male or female is not important.1 have not decided whether to go or not.间接引语位于句首时或者是间接引语提前时加hether不用if。如：Thank you, but whether I ' ll be free I' m not sure at the moment.whether可引导一个让步状语从句表示“不管:“无论”，而if不能。如：Whether he comes or not, we will begin our party on time.(

19、3)疑问词+ ever和no matter + 疑问词的区别。疑问词+ ever可引导名词性从句，在主从句中要充当一定的部分。如：Whoever breaks the rule must be punished.YOu can choose whatever you like in the shop.疑问词+ ever还可引导让步状语从句。如：Whoever breaks the rule, he must be punished,Whatever you do, you must do it well.no matter +疑问词只能引导让步状语从句。如：No matter what you

20、 do, you must do it well.No matter who breaks the rule, he must be punished.(4) when和where引导的同位语从句与定语从句的区别。when和where前面的名词若是表示时间、地点的名词，则when和where引导的是定语从句,否则则为同位语从句。如:They put forward the question where they could get the money.This is the place where the accident happened.2、名词性从句中主句和从句的时态一致(1)宾语从句中

21、主句和从句的时态保持一致，但如果从句中表示提示的是客观现象，虽然主句 是过去时态，从句仍用一般现在时。如：Hello,I didn ' t know you were in London. How long have you been here?The teacher told us that light travels at a very high speed.(2)主语从句作主语相当于单数第三人称作主语，谓语动词用单数，如果由and连接两个或两 个以上的主语从句作主语时，谓语动词用复数；由两个或多个连接词引导一个主语从句，谓语动词用 单数。如：When the meeting wi

22、ll begin has not been decided yet.When they will start and where they go have not been decided yet.When and where the meeting will begin has not been decided.3、名词性从句的词序名词性从句在句中要用陈述句语序。如：He asked me what was the matter with me.We' ve heard the news that we ' ll move into the new house.Whateve
