好的英语从句

主语从句，即在复合句中充当主语成分的句子，例如"Thathefinishedwritingthecompositioninsuchashorttimesurprisedusall"，他在很短的时间内写完作文让我们都很惊讶，此复合句主要描述的是某事让我们惊讶，某事就是该复合句的主语，因此"Thathefinishedwritingthecompositioninsuchashorttime"便是该复合句的主语从句。引导主语从句的连词主要有:从属代词:thatwhether；连接代词:whowhoeverwhomwhosewhatwhateverwhichwhichever；连接副词:whenwherehowwhy；主语从句的时态：不受主句的时态影响和限制。（1）Thathefinishedwritingthecompositioninsuchashorttimesurprisedusall.（2）Whetherwewillgoforanoutingtomorrowremainsunknown.（3）Whowillbeourmonitorhasn'tbeendecidedyet.（4）Whomwemuststudyforisaquestionofgreatimportance.（5）Whatcausedtheaccidentremainsunknown.（6）Whateveryoudidisright.（7）Whothewatchbelongstoisunknown.（8）Whatweneedistime.（9）Whatweneedaregooddoctors.小结（1）引导主语从句连词有that,whether,who,what,whatever等。（2）连词位于句首不能省略。（3）主语从句大多数情况下视为第三人称单数，但也有例外，如例（9）。

that 引导的名词性从句（主从，宾从，表从，同位语从句），从句意思完整，句子完整。that只起到引导的作用，它不充当从句的句子任何成分，也没有什么的意思。在引导宾从时that 一般可以省略。引导其他名词性从句时不省略。

whether/ if引导的名词性从句，whether/ if含有“是否”之意，如果去掉whether/ if，从句的意思是不完整的，但是句子结构还是完整的。并且它不可省略。

定语从句的引导词，是有实际意义的并且在从句中充当相应的成分（主语，宾语，表语，定于，状语），

状语从句必须要连词来引导，并不能省略，从句结构完整，但是如果少了连词的意思，整个从句意思就不完整。

理论上讲可以有无数个.主语可以是个从句，宾语可以是个从句，状语可以带个地点状语从句，带个时间状语从句，某个名词或代词再由一个定语从句或者两个定语从句修饰……举个例子：Whoever knows me can predict what I will react to such impolite words that sound so aggresive when I am not in mood.“任何一个了解我的人都料得到，在我不高兴的时候，对于听起来如此挑衅的话，我会如何反应.”这句话是我随便写的，就包含了一个主语从句，一个宾语从句，一个定语从句，一个时间状语从句.其实从句并不难，只要你能够仔细地分析，这个从句是什么从句，跟在哪个词后面，有什么作用.要学好英语，一定要学好从句，因为，在与外国人交谈或看英语文章的时候，这种从句他们常常信手（口）拈来，不懂得从句肯定是不行的.学好从句关键是要掌握从句最基本的结构以及此从句与彼从句的区别特征在哪里.。

组成句子的各个部分叫句子成分。

英语句子成分有主语，谓语，表语，宾语，宾语补足语，定语，状语等。 顺序一般是主语，谓语，宾语，宾语补足语，而表语，定语，状语的位置要根据情况而定。

1、主语 主语表示句子主要说明的人或事物，一般由名词，代词，数词，不定式等充当。 Helikeswatch'ingTV.他喜欢看电视。

2、谓语 谓语说明主语的动作，状态或特征。 一般可分为两类： 1），简单谓语 由动词（或短语动词）构成。

可以有不同的时态，语态和语气。 Westud'yforthepeo'ple.我们为人民学习。

2），复合谓语：情态动词+不定式 Icanspeakalit'tleEng'lish.我可以说一点英语。 3、表语 表语是谓语的一部分，它位于系动词如be之后，说明主语身份，特征，属性或状态。

一般由名词，代词，形容词，副词，不定式，介词短语等充当。 Mysis'terisanurse.我姐姐是护士。

4、宾语 宾语表示动作行为的对象，跟在及物动词之后，能作宾语的有名词，代词，数词，动词不定式等。 WelikeEng'lish.我们喜欢英语。

有些及物动词可以带两个宾语，往往一个指人，一个指物，指人的叫间接宾语，指物的叫直接宾语。 Hegavemesom'eink.他给了我一点墨水。

有些及物动词的宾语后面还需要有一个补足语，意思才完整，宾语和它的补足语构成复合宾语。如： Wemakehimourmon'itor.我们选他当班长。

5、定语 在句中修饰名词或代词的成分叫定语。 用作定语的主要是形容词，代词，数词，名词，副词，动词不定式，介词短语等。

形容词，代词，数词，名词等作定语时，通常放在被修饰的词前面。 Heisanewstu'dent.他是个新生。

但副词，动词不定式，介词短语等作定语时，则放在被修饰的词之后。 Thebikeintheroomismine.房间里的自行车是我的。

6、状语 修饰动词，形容词，副词以及全句的句子成分，叫做状语。用作状语的通常是副词，介词短语，不定式和从句等。

状语一般放在被修饰的词之后或放在句尾。副词作状语时可放在被修饰的词前或句首。

HelivesinLon'don.他住在伦敦。 从句是指用于复合句中担当某个句子成分的主谓结构。

虽说从句自身的句子结构是完整的， 但是它不能视为独立的句子，因为它离开了主语就无法独立、完整地表达意思。按其所能表达的意义而言，它相当于一个词或是一个词组.例如： 1) Because they talk at home while the television is on , many people think they can talk at movies as well . （状语从句）许多人在家里是边看电视边谈话，所以他们认为在电影院也可以如此。

2) Whether he comes or not doesn't make any difference to me . （主语从句） 他来与不来对我都一样。 3)There is disagreement among economists about what money is and how money is measured（宾语从句）什么是货币以及怎样计量货币经济学家之间存有分歧。

4) China is not what it used to be . （表语从句）中国不是它过去的样子了。 5) Is there any proof that the food of plant differs from that of animals ？ （同位语从句）有没有什么证据说明植物性食品不同于动物性食品？ 6) Taxes consist of money that people pay to support their government . （定语从句） 税款是人们支持政府而交的钱。

如果将上面的复合句中所有的从句都独立出来，那将是这样的： 1) Because they talk at home while the television is on 2) Whether he comes or not 3) what money is and how money is measured 4) what it used to be 5) that the food of plant differs from that of animals 6) that people pay to support their government 我们很容易看出，上面的所有这些句子既不是陈述句、疑问句，也不是祁使句，更不是感叹句。也就是说，它们不是独立的句子；也只有在附属于主句后才能获得意义如下：1）因为许多人在家里是边看电视边谈话 2）他来与不来 3）什么是货币以及怎样计量货币 4）它过去的样子5）植物性食品不同于动物性食品6）人们支持政府而交的上面的这些句子在我们中文里如同是人们常说的"半截话"；在英文中也就是个"词或词组"了。

B. 我们虽然说过，从句自身的句子结构基本是完整的，但是它不同于"独立句子"的是--每个从句的最前面都好象"戴了顶帽子"即：从属关系词。由此可以看出，从句的另一个特点是：从属关系词总是立于从句之首. C. 从句的再一个特点是：一般说来（除少数倒装的情况外），从句中的语序应该是正常语序。

D. 关于从句种类的划分有两种方法：按从句的词性划分和按从句的句子功能划分。如果按从句的词性划分，从句可分为三种：名词从句、形容词从句和副词从句。

如果按从句的句子功能划分（也就是按从句在句子中所担任的成分来划分），从句可分为：主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句。其实，这两种划分从句的方法在逻辑上是一致的.我们知道，能在句子里充当主语、宾语、表语和同位语的往往是名词、代词等，所以名词从句涵盖了主语从句、宾语从句、表语从句和同位语从句。

形容词和副词常分别在句中担当定语和状语，所以，形容词从句和副词从句其实分别是定语从句和状语从句。 名词从句名词从句在句中是一个相当于。

When I got there, I found that what I had expected to know disappeared completely as the policemen had scattered the crowd as they were ordered. 1,When I got there时间状语从句。

2,that引导一个宾语从句。 3,what I had expected to know 宾语从句中的主语从句。

4，第一个as引导一个原因状语从句。 5，第二个as引导一个方式状语从句。

后三个从句都是宾语从句中从句。

我说说我自己的理解：一般情况下，一个句子由主，谓，宾，定，状，补语等成分构成.但对于其中的主语，宾语，定语，状语，如果在一个句子中构成他们的不是词组而是个完整的句子时，我们就把他们叫做从句，即从属于主句子的句子.从句通常有自己固有的一些引导词！举个例子：What we've got is something priceless.（我们手头的这件东西是无价的.） 其中，What we've got就是句子的主语从句（它是一个由What引导的主语从句），正是这个从句充当了整个句子的主语部分.同理，宾语从句和状语从句就是主句的宾语和状语位置上出现了句子.对于这3类从句，只要多分析句子成分和熟记引导词就没问题了. 要注意的是定语从句！定语在句子里的位置相当灵活，有一点要牢记：它在句子里只起到修饰作用，即便没有它，主句子仍然是完整的！因此一个很明显的规律就是，它通常会伴随一个词组出现.例如：The place which you mentioned yesterday happens to be a famous one.（巧的很的是，你昨天提到的那个地方很出名.）其中，which you mentioned yesterday 就是句子的定语从句，它用来修饰主语The place .我们试着把定语从句去掉，原句变为：The place happens to be a famous one.不难看出，它还是个完整的句子，少了的只是修饰主语的那部分. 从句要说的东西很多，如何区分它们也是难点，楼主要了解的话要多多听课和看书才行哦！短语就不用多说了吧，看单词表时经常会看到一些由几个单词构成的”东东”吧，譬如你在学习search这个单词时，单词表会跟着出现个in search of吧，它就是search这个单词的一个短语哦，短语在构造句子时相当重要，它们会让你的句子显得更为”漂亮”，要多用。

类型与用法总结如下：

一、定语从句：

在复合句中， 修饰名词或代词的从句叫定语从句，被修饰的名词或代词叫先行词，引导定语从句的有关系代词who，whom，whose，which，that等和关系副词where，when，why等，关系代词和关系副词在定语从句中担任句子成分。

二、状语从句：

表示“当…时候”的while, when, as的用法区别是：while从句中的谓语动词必须是延续性动词；表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时，只能用when；当表示“一边…一边…”或“随着”时，只能用as。另外，用于此义的as所引导的时间状语从句谓语只能是动作动词，不能是状态动词。

三、名词性从句：

在句子中起名词作用的句子叫名词从句(NounClauses）。名词从句的功能相当于名词词组,它在复合句中能担任主语、宾语、表语、同位语、介词宾语等，因此根据它在句中不同的语法功能，名词从句又可分别称为主语从句、宾语从句、表语从句和同位语从句。

相关内容：

同位语从句：同位语从句是名词性从句中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系就是同位关系，即主表关系。

定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。This is the reason why he refused to help us. 这就是他拒绝帮助我们的原因。

时间状语从句：用表示时间的连词连接一个句子作状语，这样的主从复合句就是时间状语从句。连接时间状语从句的连接词有：when, before, after, while, as soon as, until, since. We were about to leave when he came in. 我们就要离开，就在那时他进来了。
