名词性从句是高考重要的
语法项目。掌握了以下主要考点和易错点,做好名词性从句
考题就会快而准。
考点一:名词性从句理论部分
定义:指在主从复合句中起着名词作用的句子。在主从复合句中
充当主语、宾语、表语、
同位语。
分类:根据它在句子中所起作用分为主语从句 宾语从句
表语从句 同位语从句。
连接词:引导名词性从句的连接词可分为三类:
1、连词(5个):that whetherif as if ( though)
2、连接代词(10个):what, whatever, who, whoever,
whom, whomever, whose, whoseever,
which,
whichever
3、连接副词(7个):when, whenever ,where,
wherever, how, however ,why
(一)主语从句
在复合句中充当主语的名词性从句,叫主语从句。
考点一:that在主语从句中没实际意义,不做任何成分。但是不能省略。
That
he will not come to the meeting is true.
此句也可改为:It is true that he will not come to
the meeting.
考点二:
为避免句子头重脚轻,经常用it做形式主语,主语从句在后边做真正的主语。
⑴ It + be
+ 形容词(strange, natural. true等) + that 等
It’s
strange that he didn’t come.
It is by no
means clear what the president can do to end the
strike. (2012全国).
It was never clear why the
man hadn’t reported the accident sooner.(2011·江苏卷)
⑵ It + be + 名词词组+ that从句(a pity, a shame等)
It’s a pity no wonder that he can’t go.
⑶ It doesn’t matter + how whether从句
It
doesn’t matter whether you pay by cash or credit
card in this store. (2012山东)
(4)It + be + said
reportedhopedbelievedthoughtsuggestedrequestedprop
oseddesire
d...etc +that
It’s reported that
our China team has won. It’s suggested that we
should hold a celebration.
⑸ It seems happens
+ that从句
It happensseems that I wasn’t there
that day.
(6)it引导的强调句结构:It
iswas+被强调部分+thatwho+句子其它部分。
It was in the
house where he was born that he died.
(7) It
struck sb that...It occurred to sb that 某人突然想起…
It suddenly occurred to him that he had left
his keys in the office. (2012江西)
(二)宾语从句
考
点一:that在主语从句中没实际意义,不做任何成分。在宾语从句中一般可以省略,
但但如果从句是并列句时,第二个分句前的that不能省略。
He told me
(that) he would come and that he would come on
time.
考点二:在某些动词后的宾语从句中用虚拟语气,其结构为should+动词原形,should
可
以省略。这些常用动词是:
一坚持insist; 二命令order,
command; 三建议suggest, advise, propose; 四要求desire,
demand,
request, require;另外urge和recommend
注意:insist有两个意思“坚决要求”和“坚持认为”,前者用虚拟语气,而后者用陈述语气(实
际时态);同样suggest 也有两个意思“建议”和“暗示表明”,当表示“建议”讲时用虚拟语气,否则用陈述语气(实际时态)。
The boy insisted that he
hadn’t stolen the money and should be set free.
Her pale face suggested that she was ill and
his mother suggested she( should) see a doctor.
考点三:有些动词和动词短语 ① 如:likelovehateappreciatesee
to(务必使) depend on
it+宾语从句 ②makefind think
feelconsiderbelieve it
+nadj+宾语从句。用it做形式宾
语,而将宾语从句后置。
I think it
necessary that we take plenty of hot water every
day.
I feel it a pity that I haven't been to
the get-together.
I hate it when they with
their mouths full of food.
(三)表语从句
在复合句中,
位于系动词之后作表语的从句叫表语从句。引导表语从句的关联词与引
导主语从句的关联词大致一样,表
语从句位于系动词后,有时用as ifas though引导。
考点一:常用句型
①The reason whyfor…is that…
②That’s
why+(结果) because+(原因)…
③What …is that…
④It
looksseems as ifthough…
Grandma pointed to
the hospital and said, 四川)
“Every time you eat
a sweet, drink green tea.” This is what my mother
used to tell me.(14浙
江)
From space, the
earth looks blue. This is because about seventy-
one percent of its surface is
covered by
water. (13安徽)
The reason for his being absent
is that he is ill.
The reason why he is absent
is that he is ill.
(四)同位语从句
同位语从句说明其前面的名词的
具体内容。同位语从句通常由that引导,可用于同位语
从句的名词有doubt、fact、hop
e、idea、information、message、news、problem、promise、question、truth、wish、word等。例如:
The news that
we won the game is exciting.
I have no idea
when he will come back home.
The
thought came to him that Mary had probably fallen
ill.
There is no doubtpossibility that he
can’t come.
如果名词suggestion、advice、order、
demand、 request、等词后的同位语从句的谓语
动词要用(should)+动词原形。
The suggestion that the plan (should) be
delayed will be discussed tomorrow.
同位语从句和定语从句的区别:
that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略;
that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:
I had no idea that you were
here.(that引导同位语从句,不能省略)
Have you got the
idea(that)this book gives you of life in ancient
Greece?(that引导定语
从句,作宾语,可以省略)
名词性从句 解题要点:
1.根据句中缺什么补什么的原则选连接词。如果名词性从句意思完整,不缺少任何成分,
首选
that, 因为that 不作成分,而且没有任何含义。
Experts believe
that people can waste less food by shopping only
when it is necessary.(13
北京,宾语从句)
2.在涉及到“是否…”时,whether和if 在宾语从句可互换。但是作介词宾语时只能用
whether。如:His father is worried about whether
he lose his work .
只用whether有whether to do
whether …… or not 句首whether 。如:
I can’t decide
whether to stay.
I want to know whether it’s
good news or not .
Whether they can finish
the work on time is still a problem .
3. what
在名词性从句中,意为“什么”,在从句中用来做主语、宾语、表语和定语。
①What makes
the book so extraordinary is the creative
imagination of the writer. (13北京,
主语)
I
think what_ impresses me about his painting is the
colors he uses.(14天津,主语)
②What Barbara Jones
offers to her fans is honesty and happiness.
(11·北京卷,offer sth to sb
宾语)

so confusing that it’s difficult to make out what

sth宾语)
③It is difficult for us to imagine what
life was like for slaves in the ancient world. (14
山东,
be like “像”, 缺少表语)
④It is uncertain
what side effect the medicine will bring about,
although about two thousand
patients have
taken it. (10浙江卷, 定语,“什么副作用”)

easy for the public to see what use a new
invention can be of to human life.
(11·重庆,定语,“什么用途”)
4. 名词性从句都要用陈述语序。

use his turning signal to let other drivers know
___.(10
上海)
A. he is entering
which lane B. which lane he is
entering
C. is he entering which lane
D. which lane is he entering (答案:B)
5.
whoever, whatever,
whichever等词可用于引导名词性从句也可以引导让步状语从
句, no matter
+疑问词等只可以用于引导让步状语从句。
