主语从句详解及练习-附答案
语法要点剖析 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。 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。

(他心地善良。) 这两句话分别由名词teachers，形容词 kind 作表语。 五.定语：是用来说明或限制名词的成分，可分为前置定语和后置定语，常用形容词或者相当于形容词的短语或从句担任。形容词放在名词之前，构成前置定语；相当于形容词的短语或从句放在名词的后面，构成后置定语。

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。它的位置一般在一句之首。可用作主语的有单词、短语、从句乃至句子。 1．名词作主语。 A tree has fallen across the road.

怎样区分英语中的主语,谓语,宾语等
主题：句子的成分知识讲解怎样区分英语中的主语，谓语，宾语，表语，补语，状语，定语？内容：怎样区分英语中的主语，谓语，宾语，表语，补语，状语，定语？它们有什么作用？ 提交人：张耀天同学时间：3/16/2009 23:22:54 主题：句子的成分 内容：答：①主语：用于说明人或事物执行某一动作，表明“谁”或“什么”。常由名词、代词和数词来担任。如： I love the book．The book is my friend．我喜欢这本书。这本书是我的朋友。（名词作主语） ②谓语：说明主语的动作或状态，表明“做什么”或“是什么”。常由实义动词或系动词加上表语部分来充当。如： Mother is a teacher．妈妈是一名教师。（系表作谓语） She likes music．她喜欢音乐。（动词作谓语） ③宾语是动作、行为的对象，由名词、代词、不定式或相当于名词的词、短语来担任，它和及物动词一起说明主语做什么，在谓语之后。如： He learns English well．他英语学得好。（作动词宾语） I'm interested in handwriting．我对书法很感兴趣。（作介词宾语） ④补语：说明宾语、主语“做什么”或“处于某种状态”。常由名词、形容词等词类来担任。如： The teacher named me Lucy．老师叫我露茜。（名词作补语） Very loud noises can make people ill．非常大的噪音会让人得病。（形容词作补语）⑤表语：放在连系动词之后表示主语的身份或特征的成分，表明“什么”，“怎么样”。多由名词、形容词、副词、代词、数词和介词短语来担任。如： She looks nice．她看上去很漂亮。（形容词作表语） Ann is in the classroom．安在教室里。（介词短语作表语） ⑥定语：用于修饰和限制名词或代词的成分，表明“谁的”、“怎么样”等。多由名词、数词、形容词、代词和介词短语等来充当。如： My friend is a middle school student．我的朋友是一名中学生。（名词作定语）The man with black glasses liked sweet food．戴墨镜的那个人喜欢吃甜食。（介词短语作定语） ⑦状语：用于修饰动词、形容词、副词或全句的成分。常由副词、介词短语等来充当。如： Bruce speaks English very well．布鲁斯英语说得很好。（副词作状语） Dick lived in the country a few years ago．迪克几年前住在乡下。（介词短语作状语）
(完整版)主语从句详解
主语从句详解 一、概述 在句子中起名词作用的各种从句统称为名词性从句.根据它们在句中的语法作用, 这类从句又可分为主语从句、同位语从句、表语从句和宾语从句. 二、主语从句主要有四类 （1）由连词that引导的主语从句:引导词that无含义/在句中不做成分/不可以省. 例如：That you will win the medal seems unlikely. That you are so indifferent bothers me. That she survived the accident is a miracle. （2）用连词whether 引导的主语从句: whether有含义(是否)/在句中不做成分/不可以省. 注意：引导主语从句, 不能用if, 只能用whether. 例如：Whether we will hold a party in the open air tomorrow depends on the weather. Whether she is coming or not doesn’t matt er too much. （3）用连接代词引导的主语从句 在由连接代词who, whose, whom, which, what, whoever, whomever, whichever, whatever引导的名词性从句中, 其连接代词在句中起名词性作用, 担当一定成分. 例如：What you need is more practice. What I want to know is this. Whatever we do is to serve the people. 注：whatever / whoever的功用 whatever, whoever在主语从句中不含疑问意义.它引导主语从句, 并在从句中作主语、宾语、表语等. whatever = anything that; whoever = anyone who.要注意和whatever, whoever引导的让步状语从句的区别. Whoever breaks the law should be punished. （主语从句） （＝Anyone who breaks the law should be punished. ） Whoever breaks the law, he should be punished. （让步状语从句） （＝No matter who breaks the law, he should be punished. ） （4）用连接副词when, where, why, how引导名词性从句(其连接副词有含义,在句中作状语.) 例如:Where we should leave it is a problem. When they will come hasn’t been made pubic. 三、注意点: it构成的主语从句 （1）由连词that引导的主语从句, 在多数情况下放到句子的后面, 而用代词it作形式主语. 例如：That light travels in straight lines is known to all. =It is known to all that light travels in straight lines.
英语句子成分划分详解
Grammar of Unit 1 Different parts of a sentence 概念 句子是由词按照一定的语法结构组成的。组成句子的各个部分叫做句子的成分。句子的成分包括：主语、谓语、表语、宾语（直接和间接宾语）、宾语补足语、定语和状语。主语和谓语是句子的主体部分（在英语中，一般句子必须有主语和谓语），表语、宾语和宾语的补足语是谓语里的组成部分。其他成份如定语和状语是句子的次要成分。 ▲句子成分分类 1．主语 主语是谓语讲述的对象，表示所说的“是什么”或“是谁”。一般由名词、代词、不定代词或相当于名词的单词或短语来充当，也有从句充当的现象。大多数主语都在句首。如： 讲述“谁” We work in a big factory. 讲述“什么” The classroom is very big. 数词作主语 Three are enough.三个人就够了 不定式作主语 To operate on the blind is one of the ORBIS Doctor’s job. 从句作主语 What we need is food.我们最需要的是食物. ▲在“There be …”句型中，主语的位置在中间。如：There are some bottles of milk in the box. ▲在个别句型中，主语在整个句子后面，这时前面用it作形式主语。如： It is very interesting to play the game called “treat or trick”.
It took two workers about three months to build the house. 2．谓语 谓语时用来说明主语“做什么”、“是什么”或“怎么样”， 3 表语说明主语“是什么”或“怎么样”，由名词、形容词、介词、副词、不定式及相当于名词的词或短语来充当，它的位置在系动词后面。 形容词作表语 You look younger than before. 名词作表语 My father is a teacher. 副词作表语 Everyone is here. 介词短语作表语 They are at the theatre. 不定式作表语 My job is to teach them English. 动名词作表语 Her job is training the nurses. 从句作表语 That is why he didn’t come to school yesterday. 4．宾语 ▲宾语是动作、行为的对象，由名词、代词、不定式、或相当于名词的词或短语或从句来充当，它和谓语动词一起
