第八讲 名词性从句
名词性从句(主语从句、宾语从句、表语从句及同位语
从句)是高考卷中的难点，
一般情况下，语法填空与短文改错中会出现一道题目。书面表达中的名词性从
句
绝对是“增分点”。
命题趋势：名词性从句的考查点主要集中在宾语从句上，特别是引导词
的选择与
判断，其中what和that是考查的重点。
考点一 that引导的名词性从句
1．that引导主语从句
①That you didn't know the
rules won't be the excuse for your failure.
你不知道规则不能成为你失败的借口。
②As I searched the name
Linda on the Internet，it became evident that
there're two
with the same name who look
completely different.
当我在网上搜索琳达这个名字的时候，很显然有两个看着完全不同但姓名相同的
人。
③It is announced in today's newspaper that
Trump will pay a visit to China next
week.
今天报纸上宣称特朗普下周将访问中国。
[规律总结]
连词that在引导名词性
从句时本身没有意义，在从句中不担任任何句子成分，但
引导主语从句、表语从句、同位语从句时不能省
略。在宾语从句中有时可以省略。
1．that引导主语从句位于句首时，本身无意义，但是不可以省略。
2．that从句作主语时，常用it作形式主语，常见的句型有：
①It＋be＋形容词(
obvious，true，natural，surprising，good，wonderful，fun
ny，
possible，likely，certain，probable，etc.)＋that
从句。
②It＋be＋名词词组(no wonder，an honor，a good
thing，a pity，no surprise，etc.)
＋that从句。
③It
＋be＋过去分词(said，reported，thought，expected，decided，an
nounced，
arranged，etc.)＋that从句。
2．that引导宾语从句
①Experts believe that
people can waste less food by shopping only when
it is
necessary.
专家们认为必要的时候才购物可以减少食物的浪费。
②Tom is a nice boy，except that he is sometimes
late for school.
汤姆是个很棒的男孩，除了有时候上学迟到外。
③I
find it necessary that we should spend more time
practising spoken English.
我发现我们有必要花更多时间练习英语口语。
[规律总结]
1．常见的可以接th
at(that可以省略)从句作宾语的动词有see，say，know，imagine，
disc
over，believe，tell，show，think，consider等。在可以接复合宾语的动词
之
后，如think，make，consider等，可以用it作形式宾语。
2．that从句一般不能充当介词宾语，偶尔可作except，in的宾语。
3．that引导表语从句和同位语从句
①My decision is that
all of us are to start at 6 o'clock tomorrow
morning.(表语从句)
我的决定是我们所有人明天早上6点出发。

made a promise to his boss that he'll return in
three days as long as he can
get to the
destination in time.(同位语从句)
他向他的老板承诺只要他能及时到达目的地就会在三天后回来。
[规律总结]
1．that引导表语从句时，一般不能省略。
2．that引导同位语从句时，放在某些抽
象名词如fact，hope，desire，thought，
suggestion，idea，n
ews，problem，possibility等后，对前面的名词起补充说明的
作用，that只
起引导作用，在从句中不充当任何成分，但一般不能省略。
考点二
whetherif(是否)引导的名词性从句
①It remains to be seen
whether the newly-formed committee's policy can be
put into
practice.(主语从句，不可用if代替whether)

⑤I worry about whether
he can pass through the crisis of his
illness.(介词后的宾语
从句中，不可用if代替whether)
我担心他是否能熬过这次病危。
[规律总结]
1．whether和if在宾语从句中经常可以互换，但下列情况常用whether，不用if。
(1)与or或or not连用时只能用whether；
(2)从句作介词宾语时只能用whether。
2．在引导主语从句、表语从句和同位语从句时一般用whether不用if。
考点三
who，why，how，where，when等引导的名词性从句
①As natural
architects，the Pueblo Indians figured out exactly

walls needed to be to make
the cycle work on most days.

time playing.

[规律总结]
1．
who，why，how，where，when等引导主语从句时，常用it作形式主语。
2．能接
who，why，how，where，when等引导的宾语从句的动词很多，常见的
有see，te
ll，ask，answer，know，decide，imagine，suggest，doubt，wo
nder，
show，discuss，understand，inform，advise等。

④WhateverNo
matter what you say，I will not believe
you.(让步状语从句)
无论你说什么，我都不相信。
[规律总结]
1．what引导名词性从句时，what可在从句中作主语、宾语、表语、定语。
2．“疑
问词＋-ever”可引导名词性从句，在从句中要充当一定的成分。whoever
与whateve
r表泛指，意为“无论谁”“无论什么”；whichever表示在特定范围
内选择，意为“无论……
的哪一个哪一些”。
3．“疑问词＋-ever”还可以引导让步状语从句。
4．“no
matter＋疑问词”只能引导让步状语从句。
考点五 同位语从句与定语从句的区别
①The news that they had won the game soon
spread over the whole school.(同位语
从句，进一步解释the
news的内容)
他们赢得比赛的消息很快就传遍了整个学校。
②The news
(that) you told me yesterday was really
disappointing.(定语从句，它指的
是“你昨天告诉我的那个消息”)
你昨天告诉我的消息真的很令人失望。
[规律总结]
1．同位语从
句是对前面名词的内容作进一步的解释说明，引导词that只起引导
作用，在句中不作任何成分，一般
不可以省略。
2．定语从句是对前面名词进行修饰、限制，引导词在句中作一定的句子成分。
