从句的用法归纳总结
从句的用法归纳总结从句是英语语法中重要的一部分，它是指用一个句子来作为另一个句子的一个部分。
从句可以用来表达更复杂的意思，也可以用来让句子更加简洁。
下面将从六个方面来归纳总结从句的用法。
1. 从句类型从句可以分为三大类：名词性从句、形容词性从句和副词性从句。
名词性从句是指用一个句子来作为名词，例如：I think that he will come.（我认为他会来。
）其中that he will come就是一个名词性从句。
形容词性从句是指用一个句子来作为形容词，用来描述主语或宾语的特点，例如：He is a student that always studies hard.（他是一个总是努力学习的好学生。
）其中that always studies hard就是一个形容词性从句。
副词性从句是指用一个句子来作为副词，用来描述主句中的动词或形容词的情况，例如：When he comes, we will go to the party.（当他来的时候，我们会去参加聚会。
）其中When he comes就是一个副词性从句。
2. 从句引导词从句的引导词有很多种，不同的引导词可以引导不同类型的从句。
常用的引导词有：* that：可以引导名词性从句和形容词性从句，但是不能引导副词性从句；* what：可以引导名词性从句；* who：可以引导名词性从句和副词性从句；* whom：可以引导名词性从句；* which：可以引导名词性从句；* where：可以引导副词性从句；* when：可以引导副词性从句；* why：可以引导名词性从句；* how：可以引导名词性从句和副词性从句。
3. 从句语序在英语中，主句和从句的语序一般是不同的。
主句通常采用陈述语序，而从句则可以采用疑问语序或倒装语序。
例如：Do you know where he lives？（你知道他住在哪里吗？）其中where he lives就是一个名词性从句，采用了疑问语序。

1. 定义。
- 从句是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、whom、when、why、where、how、which等引导词（Connective）引导的非主句部分。
从句在整个句子中充当一个句子成分。
2. 分类。

- 副词性从句（状语从句）- 在句中作状语，可表示时间、地点、原因、条件、目的、结果、让步、方式等意义。
二、名词性从句。
1. 主语从句。

- 连接代词：who、what、which、whom、whose等。
例如：Who will be our monitor hasn't been decided yet.（who在主语从句中作主语）。
- 连接副词：when、where、why、how等。
例如：How we can solve this problem is very important.（how在主语从句中作方式状语）。

thought came to him that maybe the enemy had fled the city．他突然想起可能敌人已经逃出城了.五、同位语从句与定语从句的区别.1、同位语从句与前面的名词是同位关系,即说明它前面名词的内容；而定语从句与前面的名词是修饰与被修饰关系,即限定它前面的名词范围,或补充一些情况.如：The news that l have passed the exam is true．我通过了考试这一消息是真的.同位语从句,即从句所表达的意思就是前面名词的内容.）The news that he told me just now is true．他刚才告诉我的消息是真的.定语从句,从句对前面名词起修饰限制作用,即“他告诉我的”那个消息,而不是别的消息.）2、引导同位语从句的that是连词,在从句中不充当任何成份,而引导定语从句的that是关系代词,除起连接作用外,还在从句中充当主语、宾语或表语等.如：The idea that computers can recognize human voices surprises many people.计算机能够识别人的声音的想法使许多人感到惊奇.that在从句中不充当任何成份.）一个名词(或其它形式)对另一个名词或代词进行修饰,限定或说明,这个名词(或其它形式)就是同位语.同位语与被它限定的词的格要一致,并常常紧挨在一起.1) 非独立的同位语：常出现在被限定词前Bruce Lee (姓名) 李小龙Graf Schmidt (称号,浑名) 施密特伯爵Doktor Wang (职称,头衔) 王博士Uncel Liu (亲戚的称呼) 刘叔叔die Stadt Shanghai (类属名称) 上海市the Province Hebei (类属名称) 河北省das Jahr 2000 (类属名称) 2000 年three Kilo tomato (度量名称) 三公斤西红柿the University Bremen (专有名词) 不来梅大学。

英语中六大从句用法总结1.主语从句1）主语从句可直接位于主语的位置，如果从句较长，谓语又较短，可用it作形式主语，而将从句放在句末。
常见的句型有：*It is a fact\a pity\a question\good news that...*It seems\appears\happened\has turned out that...*It is clear\important\likely\possible that...*It is said\reported\estimated\has been proved that...It is said that comic books create a connection between people of the same generation.、It seems that the performance is very useful.2)what引导的主语从句表示“...的东西时”，一般不用it作形式主语。
What we lack is experience.3)what,who,when,why,whether等词含有各自的疑问意义，但它们引导的主语从句，都用陈述语序。
How the plan is to be carried out should be discussed again.I did know why I felt like crying.]2.宾语从句1）宾语从句可位于及物动词、介词和某些形容词后。
连词that常可省略。
介词后一般接疑问词引导的宾语从句。
in that(因为),except that(除了),but that(只是）已构成固定搭配，其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.*All this is different from what American young people would say about friendship.*He is certain that watching so much television is not good for children.*This article is well-written except that it is a bit too long..2)宾语从句后如有宾补，要用形式宾语it来代替，而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.3)在think,believe,suppose,expect等动词后的宾语从句中，如果谓语是否定的，一般将否定词移至主句谓语上，宾语从句则变成肯定形式。
He didn't think that the money was well spent.3.表语从句表语从句出现在结构为“主语+系动词+表语从句”的句子中。

that常可省略。

常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短，将同位语从句位于谓语之后。
