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。

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。

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.

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。

【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。
