高中英语定语从句和名词性从句综合训练
名词从句
名词从句有四类：宾语从句、主语从句、表语从句、同位语从句。例如：
宾语从句：I don’t know where he will go.
主语从句：Where he will go is unknown.
表语从句：The problem is how we can get so much money.
同位语从句：We all feel sorry about the news that he failed in the game.
下面几点是学习名词从句要加以注意的：
1． whether和if都可以引导宾语从句表达“是否”意，（即引导宾语从句时if和whether 可以互换）但以下几种名词从句要用whether（不用if）引导：
（1） 引导主语从句，且在句首时。例：Whether he has won the tennis is not known.(但 It is not known whether/if he has won the tennis).
（2） 引导表语从句时。例The problem is whether he can get a job.
（3） 引导同位语从句时。例：I have no idea whether he will come.
（4） 介词后的whether从句。例：I worry about whether I hurt her feelings.
2． 位于句首引导主语从句的that不可忘。
例如：That he got the first place in the competition surprised all of us.
3． 在“The reason why…is that…”句式中that不要误为because.
例如：The reason why he didn t go to school yesterday is that he was ill.
4． 名词从句中that,what用法比较：
引导名词从句的that是连词，在句中无成份，无意义，而what是连接代词，what＝the thing(s) that.
例如：It was told in yesterday
by the factory. 无意义 the things(that)
I know that he will study. 和 I know what he will study.
That he works hard at his lessons is known to us all. 和 What he works hard at is known to us all.
5． 名词从句都是陈述语序。I know where he lives./Please tell me what her name is.
名词从句考点分析
1．They want to know ______ do to help us.
A. what they can B. how they can C. how can they D. what can they
析：此题要选陈述语序项，故应排除C、D。又因how they can do不完整，do后无宾 语，故也应排除，只有A项既是陈述语序，且what they can do完整正确地表达出“他 们能做些什么”这一意思，故答案为A。
2．His teacher ______ he ______ bright and ______ he was worth teaching.
A.didn’t think;was;that B.thought;was;whether C.didn’t think;was;× D.thought;wasn´t;× 析：观察题目，可知think后跟有and连接的两个并列宾语从句，这时前一个宾语从句的引导语that可以省略，但引导后一宾语从句的that不可省略，据此，可排除C、D两个选项。若选B项，全句意思不通，而选择A项可表达“他的老师认为他不聪明，不值得教”这一意思，且语法结构无误，故可定A是正确答案。
3．______ is done cannot be undone. A.How B.That C.What D.Where
析：do一般作及物动词使用，从题干看，需选一词作主语（逻辑上是done的宾语）。
而A.How,D.Where均是副词，不能作主语，故应排除。B项that一词只能在定语从句中作主
语，不能在主语从句中作主语，也应排除。只有选what(＝the thing that),才能正确表述“凡是做的不可不做”这一意思。
4．Take care ______ you don´t make mistakes in the coming exam.
A.of that B.about that C.for what D.that
析：take care是“注意”、“当心”意，后面可跟that引导的宾语从句来表达“当心 不要„”意思，据此，该题应选D。
5．To his surprise,the umbrella was not ___ he had put. A.which B.where C.the place D.that 析： was not后是表语，根据where在表语从句中相当于in/at the place where,将其置于空白处则可表达“伞不在他当初放的地方”意思，而C选项缺少词，不可选。A、D项皆不合用。
6．__ we can´t get seems better than __ we have.
A.what;what B.what;that C.that;that D.that;what
析：此题显然是要表达“我们得不到的东西似乎比我们得到的东西好。”这一意思，即“A seems better that B”结构，根据what＝the thing(s) that这一特点，将其置于两空白处正好可以表达出前者比后者好这一意思，故答案为A。
7．____ we’ll go camping tomorrow depends on the weather. A.If B.Whether C.That D.Where 析：此题depends前的主语从句是一个不肯定的内容，在句首表“是否”意时，只能用Whether,不可用If。故答案为B。
8．______ they are most interested in is _____ they can produce more and better cars.
A.That;how B.What;how C.What;what D.That;that
析：is前面是一个主语从句，要表达“他们最感兴趣的（东西）”这一意思，只能选what填入空白;is是表语从句，显然只有选how才能表达“如何生产更多更好的汽车”，故答案为B。
9．He made a suggestion that the English test ______ until next Wednesday.
A.will be put off B.be put off C.will put off D.put off
析：suggestion,order,adivce等词后的同位语从句谓语要用（should）do的形式，且该句中test与put off为被动关系，故选B。
10．I don´t think __ he said something like that is right. A.that B.what C.whether D.when 析：此句think后是一宾语从句，这个宾语从句的主语在is之前，它是一个被动句。
因为he said something like that已经含有主、谓、宾、状等成分，只有选不表意义，不做成分的that才合适，故选A。
定语从句 一、 定语从句与引导词
定语从句是在复合句中修饰某一名词或代词的从句。被修饰的名词或代词叫做先行词，
二、 只用that引导和不用that引导的场合
1． 只用that引导和不用that引导的场合
1） 当先行词既包括人又包括物时：He talked about the men and the books that attracted him.
2） 指物的先行词被any, every, only, very, all, no等修饰时：These are the very points that interest me./That´s the only watch that I like most.
3） 指物的先行词被序数词或形容词最高级修饰时：The first step that we are to take is very difficult./This is the second card that he gave me.
4） 先行词是指物的不定代词all,little,few,much,及everything,anything,nothing等时：There is still much that can be done about it./Have you got everything that you need?
5） 先行词是who时：Who that have seen him does not like him?
2． 不用that的场合如下：1）非限制性定语从句中 Last night ,I saw a very good film,which was about the Long March .
2）介词放在关系代词之前时 This is the man from whom I learnt the news
3）句中出现了that，或先行词是that时 I have found that which I was looking for.
四、“介词＋关系代词”用法
1． 介词的确定应依据定语从句中短语的习惯性搭配，例如：Who is the girl with whom you just shook hands?(shake hands with„是习惯性搭配)
2． 介词常受先行词的制约（即介词和先行词的搭配），例如：He built a telescope through which he could study the skies.(through which 即through the telescope)
3． 当关系代词作“动词＋介词”固定短语的宾语时，此时因定短语中的介词不能拆开移到关系代词前。例如：This is the watch which you´re looking for./He is a kind of man whom you can safely depend on.
定语从句考点分析
1． The best work ______ Luxun wrote and ______ I have read has been made into a film.
A.which;that B.that;× C.×;that D.×;×
如两个定语从句并列，关系代词作宾语时前一句的可以省略，但后一句的不可省略，故选C。
2． It was in 1969 ______ two Americans got to the moon by space ship.
It was 1969 ______ two Amerians got to the moon by space ship.
A.when B.which C.that D.×
析：第一句是强调时间in 1969,强调结构是“It was＋强调部分＋that句”，故应选C。第二句It是表时间的，先行词1969在从句中作状语，故选A。
3． Is this the house ______ Shakespeare was born?A.at which B.which C.in which D.at where 析：空白处只有填in which或where才能表达“这是莎士比亚出生的房子吗？”为C。
4． Is this house ___ Shakespeare was born? A.where B.which C.in which D.at which
析：将此句变为陈述句；This house is ______ Shakespeare was born.显然is后是一表语从句，只有选where(＝the place where)才能表达“这是莎士比亚的出生地”这一意思，故答案为A。
5． In the dark street,there wasn’t a single person ______ she could turn for help.
A.to whom B.of whom C.from whom D.that
析：“介词＋关系代词”要考虑短语搭配或与先行搭配，这道题短语turn to有关，故选A。
6． The two things _____ they felt very proud were Jim´s gold watch and Della´s hair.
A．about which B.of which C.in which D.for which
析：涉及be/feel proud of短语，故答案为B。
7． Have you ever asked him the reason ______ may explain his being late.
A.why B.that C.for which D.what
析：此题易误选A、C，因为先行词是the reason,但细观察分析，定语从句缺少主语，所以答案是B。注意what不能引导定语从句。
8． Farming is difficult ______ there is no rain. A.where B.in place C.that D.the place where 析：因为difficult是形容词，故其后不是定语从句。这儿的空白处应填引导状语从句where(＝in the place where),全句表达“在没有雨水的地方耕种困难”。这一意思，可见答案为A。
9． We need the same machine ______ in your factory.
A.which is being used B.as is being used C.that is being used D.as it is being used 析：根据“the same＋先行词”后跟as引导定语从句的原则，可知答案为B。
10．______ the people,not things ______ are most important.
A.There are;who B.Those are;that C.It is;that D.It was;who
析：仔细观察分析题目，可知只有C构成强调句才有成立。当我们要检验视其为强调句的判断是否正确时，只要将“It is (或was)„that”这三个词去掉，剩下部分读起来正确无误，则证明判断是正确的，反之是错误的。此题如不填“It is„that”三词，句子是The people,not things are
most important.语义完整正确，说明选C是对的。
