【英语】名词性从句知识点总结经典一、名词性从句1.It matters little ______ a man dies, but _____ matters much is ______ he lives.A. how; what; howB. how; it; howC. why; it; whyD. that; what; that 【答案】 A【解析】【分析】句意:一个人如何死去并不重要,重要的是他如何生活。

it为形式主语,how从句为真正的主语。

What matters much (=the thing that matters much)。

第一个how引导的是一个主语从句;it作形式主语;what引导的是主语从句;第二个how引导的是表语从句。

故选A。

【点评】考查名词性从句,本题涉及主语从句和表语从句的应用。

2. is clear to the members of the committee is that the President will not give in to their demands.A. WhoB. ItC. AsD. What【答案】 D【解析】【分析】句意:委员会成员清楚的是,总统不会向他们的要求让步。

that the President will not give in to their demands.这个句子作表语; is clear to the members of the committee这是主语从句,这里缺少主语从句的连接词,并且连接词在句中作主语,it是代词,不是了;连接词,故排除B;as作主语时,是在定语从句中,故排除C;who指人,根据表语指的事情,不是人,故排除A;what在主语从句中可以作主语或宾语,指事,符合句意,故选D。

【点评】考查名词性从句,本题涉及what引导的主语从句。

3.________ is known to us all that the old scientist, for ________ life was hard in the past, still works hard in his eighties.A. As; whoseB. It; whoseC. As; whomD. It; whom【答案】 D【解析】【分析】句意:我们都知道,那位老科学家,过去生活很艰苦,到了八十多岁还在努力工作。

第一空it is known to us all that…是个固定句型,意为“众所周知…”;第二空为介词+关系代词引导的定语从句,先行词the old scientist指人,作介词for的宾语,只能用whom,故选D。

【点评】考查名词性从句和定语从句,本题涉及固定句式it is known to us all that…和whom引导的限制性定语从句。

4.Some people believe _______ has happened before or is happening now will repeat itself in the future.A. whateverB. wheneverC. whereverD. no matter what【答案】 A【解析】【分析】句意:一些人认为之前发生的或现在正在发生的任何事情在将来都会重复发生。

Whatever has happened before or is happening now是一个主语从句,whatever既引导起这个主语从句,也在句中做主语。

BC项都属于副词的性质,都不能做主语,通常只能做状语;no matter what只能用来引导状语从句,故选A。

【点评】考查名词性从句,本题涉及"特殊疑问词+ever"引导的主语从句。

5. is even more important is the earth cooled down, water began to appear on its surface.A. When; that; whenB. What; whether; asC. What; that; asD. lt; whether; as 【答案】 C【解析】【分析】这题考查从句的用法,第一空填what引导主语从句,在主语从句中what做主语,第二空填that引导表语从句,在表语从句中,as是引导时间状语从句,句意是:甚至更重要的是:随着地球的冷却,水开始出现在表面。

选C。

6.Has it been announced ______?A. when are the planes to take offB. that are the planes to take offC. where are the planes to take offD. when the planes are to take off【答案】 D【解析】【分析】句意: 飞机什么时候起飞已经宣布了吗?此处是when引导的主语从句,且要用陈述句语序,故选D。

7.____ he will offer us enough help doesn't matter a lot to our success.A. IfB. WhetherC. BeforeD. How【答案】 B【解析】【分析】句意:他是否提供帮助对于我们的成功没有什么关系。

8.—Tell me something about your adventure in the rainforest, please.— We lost our way in the forest and ___ made matters worse was ___ night began to fall.A. what; thatB. it; thatC. it; becauseD. what; because【答案】 A【解析】【分析】考查名词性从句的连接词。

第一空what作主语从句的主语;第二空为表语从句的that。

9.They lost their way in the forest, and ___ made matters worse was that night began to fall.A. itB. whichC. thatD. what【答案】 D【解析】【分析】本题中含有一个主语从句what made matters worse,其中的what引导起这个主语从句,同时在主语从句中做主语。

AC两项不能引导主语从句,which在引导名词性从句的时候总是含有疑问的语义,而本句中并没有疑问的语义。

句意:他们在森林里迷路了,情况更糟糕的是天又黑了。

故D正确。

10._______ you don't like him is none of my business.A. WhatB. WhoC. ThatD. Whether【答案】 C【解析】【分析】句意:你不喜欢他,跟我没有什么关系。

you don't like him为主语从句,其内容已经是完整的,所以用that,且引导主语从句的that不能省略。

11.________ the weather will not clear up until next week is bad news for us.A. AsB. IfC. WhetherD. That【答案】 D【解析】【分析】考查主语从句。

句意:直到下周天气才放晴,这对我们来说是坏消息。

此处是that引导的主语从句,that无实义,只其引导作用,故答案为D。

【点评】主语从句属于名词性从句,在名词性从句中,that无实义,只起连接作用,不做句子成分;if/whether起连接作用,不做句子成分,有实义“是否”。

做题时注意看从句是否少成分。

12.______ amazed the NBA world is ______ Kobe Bryant scored 81 points just in one game.A. That, whatB. What, thatC. That, thatD. What, what【答案】 B【解析】【分析】句意:使NBA世界惊讶的是Kobe Bryant在一场比赛中得了81分。

根据句意可知,句子主语是一个主语从句,引导词即起引导作用又要做从句的一个成分,所以第一空填What;第二空是that引导的表语从句,只起引导作用,故选B。

【点评】考查名词性从句,本题涉及关系代词what引导的主语从句和表语从句的应用。

13.________ we may find interesting is that it usually takes more to be polite.A. ThatB. WhatC. WhichD. /【答案】 B【解析】【分析】句意:我们可能会发现有趣的是通常需要更多的礼貌。

此处是主语从句做主语,从句没有引导词,缺少宾语,故答案为B。

【点评】考查名词性从句,本题涉及what引导的主语从句的应用。

14.It was he said disappointed me.A. that; whatB. what; thatC. that; whichD. which; that【答案】 B【解析】【分析】句意:正是他说的话让我很失望。

这是一个强调句型,"it is/was that..."是固定搭配,"what he said"是被强调部分, 你可以发现去掉"it was that"后, 句子仍然完整。

"what he said"做主语,主语从句中"said"缺宾语用what补足,故选B。

【点评】考查主语从句的强调形式。

15.They lost their way in the forest, and ________ made matters worse was that night began to fall.A. itB. whichC. thatD. what【答案】 D【解析】【分析】句意:他们在森林里迷路了,情况更糟糕的是天又黑了。
