完整版)名词性从句用法归纳

完整版)名词性从句用法归纳名词性从句是指在句子中作名词角色的句子,可以充当主语、宾语、表语、同位语、介词宾语等。
名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
引导名词性从句的连接词可以分为三类。
第一类是从属连词,包括that、whether和if。
在宾语从句或表语从句中,that 有时可以省略。
第二类是连接代词,包括what、who、which 等。
这些代词在从句中做成分,不可以省略。
第三类是连接副词,如when、where、how等,也不可以省略。
在一些情况下,that可以省略,如定语从句中做宾语、引导宾语从句或表语从句时。
但在定语从句中做主语、由that引导同位语从句时,以及宾语从句中真正的that不可以省略的情况下,that不能省略。
主语从句是指作句子主语的从句。
主语从句通常由从属连词that、whether等,连接代词what、who、which等,以及连接副词how、when、where等引导。
2、连接词的使用:连接词在句子中起到连接的作用,其中that在句子中没有实际的意义,只是起到连接从句和主句的作用。
而连接代词和连接副词则在句子中既保留了自己的疑问含义,又起到连接从句和主句的作用,同时在从句中充当从句的成分。
例如,whom和who指人,what指物,而XXX和whoever则表示泛指意义。
举个例子,What he wants to tell us is not clear.表示他想告诉我们什么并不清楚。
另外,为了避免句子头重脚轻的情况,有时我们会用形式主语it代替主语从句,并将主语从句放在句末。
这种情况下,主语从句后的谓语动词一般使用单数形式。
常用的句型有:(1)It + be +名词+ that从句,如It is a fact that(事实是);(2)It + be +动词的过去分词+ that从句,如It is said that(据说);(3)It +不及物动词(vi)+ that从句,如It seems that (似乎);(4)It + be +形容词+ that从句,如It is naturalthat(很自然)。

名词性从句的若干关联词用法比较
江西省兴国县第三中学常峰
名词性从句关联词的选择一般遵“两看”的原则,即一看关联词的意义;二看关联词在从句中所作的成分.现将若干易混淆的关联词的用法作一比较.
1.That与what. That引导名词性从句时不作成分,没有意义,只起连接作用; what引导名词性从句时须在从句中作成分且含有“什么”“所……的”等意义.故选用这两词的标准是看名词性从句的句意是否完整,成分是否齐全.
例1.----Lily passed the entrance exam made her parents very excited.
A. What
B.If
C.That
D.Because
析:该题选 C.题干中的主语从句“----Lily passed the entrance exam”意思完整,成分齐全,只缺一关联词,故选That.
例2.----our weather will be like in the future is hard to predict, but scientists are working hard to find out.
A.What
B.Whether
C.That
D.Which
析: 该题选 A.显然主语从句“----our weather will be like in the future”中的介词like缺宾语且从句意考虑也缺“什么”之意,故选
what.
2.if与whether。
引导主语,表语,同位语从句多用whether不用if;引导
介词的宾语从句只用whether不用if; whether引导的宾语从句可置句
首表强调,而if的不可; 引导动词的宾语从句两者基本通用(discuss
的宾语从句只用whether不用if),但if引导的宾语从句可以是肯定的
也可是否定的, whether引导的宾语从句只能是肯定的; whether与or
not可以连着使用也可分开使用,而if与or not只能分开使用.
例1.The question is ----he will speak at the meeting tomorrow.
A. whether
B.Who
C. if
D.what
析:该题选A. whether在此引导表语从句, 不用if.而选B, D显然句意
不通或在从句中无成分可作.
例2.I don’t know ----they will succeed or not.
A. how
B.if
C.whether
D.when
析:该题选C.此处whether与or not分开使用引导宾语从句.
3.who与whoever.两者都指人,在从句中可作主语也可作宾语.但who引导
的从句表示一件事或情况; whoever引导的从句表示某个人或某些人.
例1.---- broke the window should be punished.
A. Who
B.Whom
C.Whomever
D.Whoever
析: 该题选D. 主语从句“---- broke the window”缺主语,故排除B, C.
根据主句谓语“should be punished”可判断主句的主语应是人而不是
事,因为“被惩罚”的对象只能是人,而不能是事.
例2.----will come with us hasn’t been decided.
A. Who
B.Whom
C.Whomever
D.Whoever
析:该题选 A.情况与上例类似,不过此题主句谓语是hasn’t been
decided,其对象应该是事,故选Who。
4.Whether/if与that.三者在名词性从句中均不作成分(名词性从句的所有关联词也只有这三个不作成分。
),两者的差异在于一,Whether/if
有“是否”的意思,而that无词义;二,that引导的从句可以是肯定
的也可是否定的,而Whether/if表是的句意必须是疑问的。
例1.I am wondering ----you would care to spend the evening with
us.
A. that
B.what
C. When
D.whether/if
析:该题选D.根据主句谓语am wondering可推断其对象(宾语)应该
是含疑问语意的,故选whether/if。
例2.We have decided----the meeting will be held tomorrow .
A. that
B.what
C. When
D.whether/if
析: 该题选A. 根据主句谓语have decided可推断其对象(宾语)应
该是肯定或否定的事实,而不是含疑问的,故选that。
[强化训练]:
1.Our country is quite different from ----used to be.
A. what it
B.what
C.that
D.what was
2. ----the teacher said is ----we wanted to consider.
A. What that
B.That that
C.What what
D.That what
3. ----dose wrong is to be answered for in the end.
A. Who
B.Whoever
C.No matter who
D.Anyone
4. I am in doubt ----I should agree to the plan.
A.that
B.what
C.whether
D.if
5. There is no doubt----they will win the match.
A.that
B.what
C.whether
D.if
6. ----he will attend the meeting, I am not sure.
A.that
B.what
C.whether
D.if
7. I don’t care ----it doesn’t rain.
A.that
B.what
C.whether
D.if
8. We are discussing ----John could join us .
A.that
B.what
C.whether
D.if
[参考答案简析]:
1.A 。
该题中介词from的宾语从句既缺主语又缺表语,惟有A项能补足这两个成分。
2.C.该题中的主语从句和表语从句都缺宾语,故选C.
3.B.根据主句谓语is to be answered for可判断主句的主语应是人,而No matter who不能引导名词性从句。
4.C. doubt的同位语从句一般用whether或that引导。
主句为肯定时用whether,否定时用that,即doubt表示存在疑问用whether,
no doubt表示不存在疑问用that,与上面论述不矛盾。
5.A.见第4题注解。
6.C.此题属whether引导的宾语从句前置的情况。
7.D 此题属if引导否定的宾语从句的情况,而whether无此用法。
8.C 此题属whether引导discuss的宾语从句的情况,而if无此用法。
