英语句子成分主语谓语宾语表语定语状语补语同位语讲解[整理版]

英语句子成分主语谓语宾语表语定语状语补语同位语讲解[整理版]主语从句即一个句子作主语如:what he said is true. what he said是一个句子具备最短的句子所应有的主语(he)和谓语动词(said)。

又应有what引导词所以做从句，又Is 是大句子中的谓语动词，在主句中，所以其前的成分为主语，主语是一个句子，叫做主语从句。

宾语从句和主语从句同理，事不过宾语从句是在谓语动词后的句子，谓语后的成分是宾语。

如: He said that the girl is beautiful. that the girl is beautiful为宾语从句，做动词said后的宾语。

表语从句依然如此，只是动词为系动词或感官动词，动词后为表语从句。

如:He is who I am looking for. who I am looking for. 为表语从句，做系动词is的表语。

前几种句子均为名词性从句，引导词指人用who whose whom,指物用which，what。

其中which有范围 what没范围。

连接副词有:when where why how四种。

如:I don't know where he is going.(宾从)定语从句为形容词性从句，即一个句子像一个形容词，修饰一个名词或代词，而被修饰的词在句子前面，叫做先行词。

如:The girl who wears a red coat is my classmate. 其中who wears a red coat 是定语从句，修饰the girl, 所以the girl为先行词，主句为The girl is my classmate。

定语从句引导词指人和名词性从句相同，who whose whom;指物只用which，没有what;that 即指人又指物。

关系副词没有how 即 when,where,why.如: The year when I arrived there is 2000. (when I arrived there为从句)状语从句考点比较简单，记住他引导词的意思就行了，如时间是when while 等，地点是where wherever,原因是why 结果because等就可以了英语主谓宾表定状补成分精简讲解一(主语:主语(subject) 是一个句子的主题( theme)，是句子所述说的主体。

高中同位语从句详细讲解与练习(附答案)

同位语从句讲义1．定义：用作同位语的从句叫做同位语从句。

2.用法：同位语从句的先行词多为fact, news, idea, thought, question, reply, report, remark等，关联词多用从属连词。

如：They were all very much worried over the fact that you were sick.对你生病这件事，他们都很焦虑。

Where did you get the idea that I could not come?你在哪儿听说我不能来？Early in the day came the news that Germany had declared war on Russia.德国已对俄国宣战的消息一大早就传来了。

注：同位语从句偶尔由从属连词whether引导。

如：I have no idea whether he’ll come or not.我不知道他是否来。

连接代词who, which, what和连接副词where,when, why, how亦可引导同位语从句。

The question who should do the work requires consideration.谁该干这项工作，这个问题需要考虑。

W e haven’t yet settled the question where we are going to spend our summer vacation.到哪儿去度暑假，这个问题我们还没有决定。

It is a question how he did it.那是一个他如何做了此事的问题。

1．that引导的同位语从句与定语从句之区别?that引导的同位语从句that引导的定语从句句法功能上that只起连接从句的作用，无意义。

在从句中不充当句子成分。

不可省。

that替代先行词在从句中不仅起连接作用，还充当一个句子成分。

主语从句与同位语从句详解

【主语从句】主语从句是指在句子中做主语的从句。

引导主语从句的词有连词that，whether；连接代词who，what，which以及其强调形式whoever，whatever，whichever；连接副词when，where，how，why等。

例如：That she was able to come made us very happy．Whether she will come or not is still a question．What we need is more time．Where she has gone is a mystery．在主语从句中，为了保持句子的平衡，我们常常把主语从句后置，而以形式主语it代替。

例如：That he misunderstood me is obvious．通常说成：It is obvious that he misunderstood me．When the plane is to take off has not been announced．通常说成：It has not been announced when the plane is to take off．引导主语从句位于句首的连词不能用if，可以使用whether。

例如：If he comes or not doesn’t matter．应该为：It doesn’t matter if he comes or not．或Whether he comes or not doesn’t matter．that引导的主语从句放在句首时，that不能省略。

例如：That he was chosen made us very happy．注意这种结构构成的一些常见句型，如：It is said / reported that …．据说/据报道……。

It must be pointed out that …．必须指出的是……。

名词性从句详解及练习

各类从句详解英语从句可以分为名词性从句、定语从句和状语从句三大类：下面我们逐一进行说明：一、名词性从句（主语从句、表语从句、宾语从句、同位语从句）主语从句、表语从句、宾语从句和同位语从句在复合句中的充当的成分和其名称相同，分别作主句的主语、表语、宾语和同位语。

上述这四种从句均被称为名词性从句。

所有的名词性从句均不能用逗号分开，并且它们都用相同的关联词，关联词如下：①主从连词：that (无意义), whether (是否), if (是否)（在句子中不充当任何成分）②连接代词：who (谁), whom (谁), whose (谁的), what (什么), which (哪一个)③连接副词：when (什么时候), where (什么地方), how (怎样), why (为什么)主从连词只起连接作用，连接代词和连接副词除了起连接作用外，还充当从句某一个成分。

另外，可以用whatever, whichever, whoever, who(m)ever等连接代词引导名词性从句，来加强语气。

下面分别对各种名词性从句进行介绍（一）主语从句（subject clause）在主句中用作主语的主谓结构称之为主语从句。

例如：That he will come to the discussion is certain.他来参加讨论是确定的。

That the moon moves round the earth is well known to all of us.月球绕地球转动，这是我们大家都熟知的。

When the meeting is to be held has not yet been decide.会议什么时候召开还没有决定。

主语从句放在句首，句子常常显得比较笨重，因此通常可以把it放在句首，作形式主语，而将主语从句放在后面。

例如上面的句子可以分别改写为：It is certain that he will come to the discussion.It is well known to all of us that the moon moves round the earth.It has not yet been decide when the meeting is to be held.下面再举一些例句：What they are after is profit.他们追求的是利润。
