英语名词性从句专项训练答案含解析
一、初中英语名词性从句
1．________
his failure lies is expected ________ clear to us.
A. What…
to make B. How…
made C. Where…
to be made D. Why…
making
【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.
2．
is
clear to the members of the committee is that the President will not
give in to their demands.
A. Who B. It C. As D. 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;
whose B. It;
whose C. As;
whom D. 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. whatever B. whenever C. wherever D. 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。

A. When;

that; as D. 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．It________that
the road will be closed tomorrow for repairs.
A. was
announced B. has
been announced
C. had
been announced D. would
be announced
【答案】B
【解析】【分析】本题考查动词的时态和语态。题干句子中that到句子结束是宾语从句，且从句动词用“will＋动词原形”表示将来，由此推断出空白处谓语动词应用现在的某种时态，在所给四个选项中，只有B项正确。
【点评】考查现在完成时的被动语态，其结构是have/has
+been +done。需要注意宾语从句的时态。主句用现在时，从句所需的任何时态。
7．Has
it been announced ______?
A. when

8．____

girlfriend and she agreed.
A. What;
that B. That
; that C. What;
whether D. It;
that
【答案】A
【解析】【分析】句意：让我更不高兴的是那个男孩要求我的朋友做他的女友，她同意了。第一空填what,它一方面在句子中引导主语从句,另一方面又在主语从句中作主语；第二空用that引导表语从句且从句中不缺成分,表示对前面情况的说明。故选A。
【点评】考查了名词性从句，本题涉及what引导的主语从句以及that引导的表语从句。
10．It
is a rule in his family that _______ comes home first should cook the
dinner.
A. anybody B. who C. whoever D. 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。
11．_______
you don't like him is none of my business.
A. What B. Who C. That D. Whether
【答案】C
【解析】【分析】句意：你不喜欢他，跟我没有什么关系。you

A. As B. If C. Whether D. 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。
13．______

stronger, more prosperous economy.
A. Which B. What C. It D. As
【答案】C
【解析】【分析】句意：医疗保健的进步将促进一个更强大、更繁荣的经济，这是我们的信念。that引导的是主语从句，故空格处应该用it作形式主语，代替真正的that引导的主语从句。故答案选C。
【点评】考查it的用法，以及主语从句的应用。
