选C。

第一空what作主语从句的主语;第二空为表语从句的that。

5.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。

6.It is a rule in his family that _______ comes home first should cook the dinner.A. anybodyB. whoC. whoeverD. who that【答案】 C【解析】【分析】句意:在他的家里有个规定,就是先到家的人要先做饭。

whoever 有两个词义:1no matter who,在这种用法时引导一个让步状语从句;2anybody that,在这种用法时,它连接一个名词性从句,在本题中它连接的是主语从句。

这里就是第二个用法。

所以选C。

7.________ 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。

8.They lost their way in the forest, and ________ made matters worse was that night began to fall.A. thatB. itC. whatD. which【答案】 C【解析】【分析】句意:他们在森林里迷路了,更糟糕的是天开始黑了。

根据连词and可知,本句需要一个引导主语从句的连接词,该词同时还要能在从句里充当主语。

that不能在句中作成分;it不能引导主语从句;which意为“哪一个”,不符合本句语境。

排除A、B、D三项。

故选C。

【点评】考查名词性从句,本题涉及what引导的主语从句的应用。

9.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。

10._______ is troubling me is ______ I don't understand ________ he saidA. What; that; whatB. What; what; whatC. That; that; whatD. Why; that; which 【答案】 A【解析】【分析】句意:我烦恼的是我不明白他说的话。

第一空是主语从句,从句中缺主语,要用What;第二空是表语从句,从句不缺成分,所以要填that;第三空是宾语从句,从句中的动词understand缺宾语,要填what。

故选A。

【点评】考查名词性从句,本题涉及主语从句,表语从句和宾语从句的应用。

11.________ his failure lies is expected ________ clear to us.A. What… to makeB. How… madeC. Where… to be madeD. Why… mak ing【答案】C【解析】【分析】句意:他的失败之处有可能被我们弄清楚。

分析句子可知,主语从句中的lie为不及物动词,所以主句中缺少状语,因此填where。

expect sth.to do.固定短语,“期望某事发生”,sth. be expected to do.意为”某事有可能发生“。

make sth. clear to sb为固定搭配,意为“向某人阐明某事,使某人弄清某事”。

本句中make的宾语是where his failure lies 是被弄清楚,要用动词不定式的被动形式。

因此选C。

【点评】考查名词性从句及固定搭配,本题涉及主语从句和固定短语expect sth.to do.12.________ manners are very important in every country is known to all,but the trouble is that different countries have different ideas about ________ good manners are.A. That; whatB. That; thatC. What; thatD. What; what【答案】 A【解析】【分析】句意:众说周知,礼貌在每一个国家中都是非常重要的,但是麻烦是,不同的国家对于什么是良好的礼貌有着不同的认识。

逗号前有两个谓语动词,一个是are,一个是is known,故是两句话,需填连词连接这两句话,根据句意可知,前面是主语从句,故填that,此处的that,只起连接作用不作任何成分。

about是介词,其后是个句子故应填连词把这两句话连接起来,所缺词作are的表语,故填what。

因此选A。

【点评】考查名词性从句,本题涉及that引导的主语从句和what引导的宾语从句。

13._______is known to us all is that Johnson broke his promise ______ he would come to help me as soon as possible.A. It; thatB. What; thatC. As; whichD. What; which【答案】 B【解析】【分析】句意:我们都知道,Johnson违背了他会尽快来帮助我的诺言。

分析句子结构可知,第一空为主语从句,从句中缺少主语,所以用what,第二空为同位语从句,从句结构完整,所以用that解释promise的内容,故选B。

【点评】考查名词性从句,本题涉及主语从句和同位语从句。

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.He took a trip to Beijing last week and ________ he saw at the Forbidden City impressed him deeply.A. thatB. howC. whatD. which【答案】 C【解析】【分析】句意:上周他到北京旅行了,他在故宫所看到的给他留下了深刻的印象。
