高中英语语法总结-名词性从句
首先,名词性从句中宾语从句与其他三个不同,在that;
whether
和if
等的用法上。
其次,要搞明白做的是哪种名词性从句。我用的一个笨办法是让学生往前看:没东西了,自然是主语从句,要不就是前面有一个形式主语it,前面是及物动词或介词是宾语从句,前面是系动词是表语从句,前面是一个名词是同位语从句。要关注引导词的细微差别。
最后,扎实的基本知识:从句并不总是老老实实地跟在前面说的那些词的后面,注意颠倒顺序的情况和中间插入其他内容的情况。
其他的可以看语法书讲解:看从句中是否缺成分,弄明白各种引导词的用法和含义。
英语名词性从句的思维导图
一.名词性从句
主语从句、表语从句、宾语从句、同位语从句,在整个句子中所起的作用,相当于一个名词。因此,这四种从句通称为名词性从句。
引导名词性从句的连接词可分为三类:
连接词:that, whether, if (不充当从句的任何成分)
连接代词:what, whatever, who, whoever, whom, whose, which.
连接副词:when, where, how, why
1. 主语从句
作句子主语的从句叫主语从句。主语从句通常由从属连词that,whether,if和连接代词what,who,which,whatever,whoever以及连接副词how,when,where,why等词引导。that在句中无词义,只起连接作用;连接代词和连接副词在句中既保留自己的疑问含义、又起连接作用,在从句中充当从句的成分。例如:
What he wants to tell us is not clear. 他要跟我们说什么,还不清楚。
Who will win the match is still unknown. 谁能赢得这场比赛还不得而知。
It is known to us how he became a writer. 我们都知道他是如何成为一名作家的。
Where the English evening will be held has not yet been announced. 英语晚会将在哪里举行,还没有宣布。
有时为避免句子头重脚轻,常用形式主语it代替主语从句作形式主语放于句首,而把主语从句置于句末。主语从句后的谓语动词一般用单数形式。常用句型如下:
(1) It + be + 名词 + that从句
(2)It + be + 形容词 + that从句
(3)It + be + 动词的过去分词 + that从句
(4)It + 不及物动词 + that 从句
另注意在主语从句中用来表示惊奇、不相信、惋惜、理应如此等语气时,谓语动词要用虚拟语气“(should) +do”,常用的句型有:
It is necessary (important, natural, strange, etc.) that …
It is a pity (a shame, no wonder, etc.) that…
It is suggested (requested, proposed, desired, etc.) that…
2. 宾语从句
名词句用作宾语的从句叫宾语从句。引导宾语从句的关联词与引导主语从句表语从句的关联词大致一样,在句中可以作谓语动词或介词及非谓语动词的宾语。
1. 由连接词that引导的宾语从句
由连接词that引导宾语从句时,that在句中不担任任何成分,在口语或非正式的文体中常被省去,但如从句是并列句时,第二个分句前的that不可省。例如:
He has told me that he will go to Shanghai tomorrow. 他已经告诉我他明天要去上海。
We must never think (that) we are good in everything while others are good in nothing. 我们决不能认为自己什么都好,别人什么都不好。
注意:在demand、order、suggest、decide、insist, desire, demand, request, command等表示要求、命令、建议、决定等意义的动词后,宾语从句常用“(should)+ 动词原形”。例如:
I insist that she (should) do her work alone. 我坚持要她自己工作。
The commander ordered that troops (should) set off at once. 司令员命令部队马上出发。
2. 用who,whom, which, whose, what, when, where, why, how, whoever, whatever, whichever等关联词引导的宾语从句相当于特殊疑问句,应注意句子语序要用陈述语序。例如:
I want to know what he has told you. 我想知道他告诉了你什么。
She always thinks of how she can work well. 她总是在想怎样能把工作做好。
She will give whoever needs help a warm support. 凡需要帮助的人,她都会给予热情的支持。
3. 用whether或if引导的宾语从句,其主语和谓语的顺序也不能颠倒,仍保持陈述句语序。此外,whether与if 在作“是否”的意思讲时在下列情况下一般只能用whether,不用if:
a. 引导主语从句并在句首时;b. 引导表语从句时;c . 引导从句作介词宾语时;d. 从句后有“or not”时;e. 后接动词不定式时。例如:
Whether there is life on the moon is an interesting question. 月球上有没有生命是个有趣的问题。
The question is whether she should have a low opinion of the test?
Everything depends on whether we have enough money. 一切要看我们是否有足够的钱。
I wonder whether he will come or not. 我想知道他来还是不来。
Can you tell me whether to go or to stay? 你能否告诉我是去还是留?
4. 注意宾语从句中的时态呼应,当主句动词是现在时,从句根据自身的句子情况,而使用
不同时态。例如:
he studies English every day. (从句用一般现在时)
he studied English last term. (从句用一般过去时)
I know (that) he will study English next year. (从句用一般将来时)
he has studied English since 1998. (从句用现在完成时)
当主句动词是过去时态(could, would除外),从句则要用相应的过去时态,如一般过去时,过去进行时,过去将来时等;当从句表示的是客观真理,科学原理,自然现象,则从句仍用现在时态。例如:
The teacher told us that Tom had left us for America.
5. think, believe, imagine, suppose等等动词引起的否定性宾语从句中,要把上述主句中的动词变为否定式。即将从句中的否定形式移到主句中。例如:
We don’t think you are here. 我们认为你不在这。
I don’t believe he will do so. 我相信他不会这样做。
3. 表语从句
在句中作表语的从句叫表语从句。引导表语从句的关联词与引导主语从句的关联词大致一样,表语从句位于连系动词后,有时用as if引导。其基本结构为:主语 + 系动词 + that从句。例如:
The fact is that we have lost the game. 事实是我们已经输了这场比赛。
That’s just what I want. 这正是我想要的。
This is where our problem lies. 这就是我们的问题所在。
That is why he didn’t come to the meeting. 那就是他为什么不到会的原因。
It looks as if it is going to rain. 看上去天要下雨了。
需要注意的,当主语是reason时,表语从句要用that引导而不是because。例如:
The reason why he was late was that he missed the train by one minute this morning
4. 同位语从句
同位语从句说明其前面的名词的具体内容。同位语从句通常由that引导,可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。例如:
The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
同位语从句和定语从句的区别:
that作为关系代词,可以引导定语从句,充当句子成分,在从句中作宾语时可以省略; that引导同位语从句时,起连词的作用,没有实际意义,不充当句子成分,一般不能省略。
试比较下面两个例句:
I had no idea that you were here.(that引导同位语从句,不能省略)
Have you got the idea(that)this book gives you of life in ancient Greece?(that引导定语从句,作宾语,可以省略)

英语语法名词性从句
引导这些名词性从句的关联词包括:
从属连词that, if, whether;
连接代词who, whoever, whom, whomever, which, whichever, what, whatever, whose;
连接副词where, when, why, how。
其中, 从属连词只起连接作用, 在从句中不充当任何句法成分,而连接代词和连接副词既起连接作用, 在从句中又充当一定的成分.
That Owen should have married his cousin is not at all surprising. (主语从句)
The fact is that he didn’t go to the dinner party. (表语从句)
I don’t know if he will attend the meeting. (宾语从句)
Have you heard the news that Mary is going to marry Tom? (同位语从句)
你听说玛丽要和汤姆结婚的消息了吗?(that引导同位语从句)
[提示]
在含有主语从句的复合句中, 为保持句子平衡, 常用it作形式主语,而将真正的主语从句置于句末.
It’s well-known that water is indispensable to life.(形式主语)
2. 为保持句子平衡, that引导的宾语从句也常用it代替, 而将真正的.宾语从句置于主句句末。这常常出现在主句有形容词或分词作宾语补足语的情况下。
He made it quite clear that he preferred to live here.
3. 从属连词whether和if都作“是否…”解, 但if不可引导主语从句和表语从句。whether可与or(not)连用, 而if不可以。
I don’t know whether (if) she is at home. Whether she comes or not makes no difference.
4. that和what引导名词性从句的区别: that在从句中不充当成分,而what在从句中充当一定的成分, 如主语、表语、宾语等。that可省略, what则不可省。
He always means what he says. She suggested (that) he do it at once.
5. 同位语从句大多由从属连词that引导, 常跟在下列名词后面, 如fact, idea, opinion, news, hope, belief等, that不可省。同位语从句一般用来解释说明这些名词的具体含义和内容。
We are familiar with the idea that all matter consists of atoms.
The news that we are invited to the conference is very encouraging.
