名词性从句包括主语从句、表语从句、宾语从句和同位语从句。
引导名词性从句的连词有that、if、whether;
连接代词who、whom、whose、what、which、whoever/whatever...;连接副词when、where、how、why等.
名词性从句都有其不同的含义及其用法。使用名词性从句时要注意以下几点:
1.that引导的名词性从句
that引导名词性从句时本身无意义,只起连接作用,也不在句中作任何成分。它引导的名词性从句结构和意义都完整,往往用于陈述事实。引导主语从句、表语从句和同位语从句时,that不能省略。引导宾语从句时,在口语和非正式文体中,that可省略。但下列情况下,that不可省略:
(1)that从句作介词的宾语;
She remembered nothing about him except that he was from China.
(2)that引导的从句位于句首时;
That Earth goes around the sun is known to us all.
(3)宾语从句前有插入语时;
We hope , on the contrary , that he will go hiking with us.
(4)动词后有多个that引导的宾语从句时,第一个that可省略,从第二个从句开始that不可省略;
He told me (that) he had to go and that he would be back soon.
(5)it作形式宾语时,that引导的宾语从句中that往往不可省略。
He has made it clear that the meeting will not be put off.
2 it 做形式主语的句式：
(1)It+be+形容词(likely、unlikely、wrong、important、certain、clear、obvious、strange、normal等)+that从句
It isn’t likely that I should accept such a good suggestion.
(2)It+be+名词(短语)(good news、a fact、an honour、a wonder、no wonder等)+that从句
It’s no wonder that he could succeed.
(3)It+be+过去分词(heard、reported、、decided、suggested、advised、ordered、remembered、thought、considered、well-known、announced等)+that从句
It is said that the meeting has been put off until next month.
“ It + be+ ordered/requested/ suggested /advised /insisted /required...+that从句”结构中,从句谓语应用“(should+)动词原形”。
It is ordered that you (should) spend more time in studying.
(4)It+特殊动词或短语(happen、matter、seem、appear、turn out、occur to、make no difference等)+that从句
It suddenly occurred to her that Jim was afraid of being away.
3.whether与if的用法
(1)用whether或if均可的情况
①whether可引导各种名词性从句。引导大部分动词后的宾语从句时,两者均可。
②it作形式主语,且主语从句在句末时,两者均可引导主语从句。
It’s uncertain whether/if he’ll leave this evening.
(2)用whether而不用if的情况
①主语从句和宾语从句置于句首时;
Whether we can have clean drinking water lies in what effective measures will be taken by the government about water pollution.
②引导表语从句和同位语从句时;
The problem is whether the air pollution can be controlled.
He asked me the question whether we should give money to the homeless.
③引导介词的宾语从句时;
It depends on whether we have enough money.
④引导词与or not连用时;
I don’t know whether or not the news is true.
=I don’t know whether the news is true or not.
⑤引导词后接to do时;
They don’t know whether to leave.
⑥有些动词如leave , put , discuss , decide等后的宾语从句;
We discussed whether we should hold a meeting.
⑦避免用if引导产生歧义时。
Let me know whether you are coming to our party.
4.what和that的区别
what引导名词性从句时意思相当于the thing that,在从句中主要作主语、宾语和表语;that引导名词性从句时本身没有意思,在句中不作句子成分。that引导宾语从句时可省略。
The villagers have already known what we’ll do is to rebuild the bridge.
What I can’t understand is why he was absent for class.
Some researchers believe that there is no doubt that a cure for AIDS will be found.
5.whether和that的区别
whether和that引导名词性从句时都不作句子成分,但是whether有“是否”的意思,而that只起连接作用,在句中没有任何意思.
We’ve offered her the job , but I don’t know whether she’ll accept it.
Whether we can get enough money for the project is still a question.
That she will refuse your help seems unlikely.
6.who和whoever都可以引导主语从句,只能置于句首,不能用形式主语it代替。who在从句中做主语,whoever相当于the person who...或anyone who...,可同时作主句和从句的主语。
Who will be elected has not yet been decided.
Whoever (Anyone who) comes last law should be punished.
