一：英语中各类从句怎么写？
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。表语从句除可用that,what,when,why,whether,how等引导外，还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句，不可用because.
Perhaps the most important thing to remember is that there i......余下全文>>
二：英语中的从句类型有哪几种
区分英语从句的“小窍门”
根据英语从句在句子中的句法作用,从句可分为三类:名词性从句,形容词性从句和副词性从句。通过对引导从句的各种引导词进行观察,我们不难发现,有的从句可以直接从引导词的形式和意义上来区分。如:Though the old man is over seventy, he still sees well and hears well. 我们一读此句,就可以认定,由Though引导的从句是一个让步状语从句。因为though只能引导让步状语从句,不能引导其它从句,但是有些引导词却能引导多种从句。如引导词when:既可以引导时间状语从句又可以引导定语从句,还可以引导名词性从句。此外,象that,where等,三类从句均可引导;who既可引导定语从句,又可引导名词性从句;so that 即可引导目的状语从句,又可引导结果状语从句……因此,这些形同义不同的引导词给我们理解、掌握、运用各种从句带来了很大困难。另外,搞不清楚从句在句子中所起的作用,就不能正确理解原文。那么,怎样正确区分各种形同义不同的引导词引导的从句呢?
1、 分析句子结构以区虽从句的种类
遇到一个复合句,首先要分析其句子结构,看从句在整个句子中起什么作用,那么它就是什么从句。
2、 分析引导词的句法作用以区别从句的种类
that这个词即是引导同位语从句,又可引导定语从句,这种两种从句从形式和结构上看特别相似,如何区分呢?
区分that引导的是同位语从句还是定语从句的方法是,看that在从句中是否充当句子成分,若that在从句中不充当任何成分,则为同位语从句;若that在从句中充当主语或宾语,则为定语从句。
3、 根据被修饰词来判断从句的种类
定语从句常常修饰一些具有实际意义的名词,如:the film;the student;the book;a house等等。而同位语从句常常修饰一些表示抽象概念的名词,如fact、idea、promise、truth等,用来说明这些名词所表示的具体内容。状语从句在句子中常用来修饰谓语动词。
4、 根据从句前词的词性来判断从句的种类
宾语从句分两种:动词的宾语从句、介词的宾语从句。宾语从句前肯定是动词或介词。定语从句是用来修饰名词或代词的,所以其前一定是一个名词或代词。
5、 根据上下文意义和结构形式上区分从句的种类
如so that即可引导目的状语从句,又可引导结果状语从句,如何区分呢?主要从以下两点来区分。
①根据上下文意义判断。“以便……”表示目的,是目的状语从句,“以致于……”,“结果……”表示结果,是结果状语从句。
②从结构形式上来分辨。so that前有逗号,为结果状语从句,反之,则为目的状语从句。有时,so that前无逗号,这里要看从句中有无can、could、may、might、will、would、should 等情态动词,如果有,则多是目的状语从句,若没有,则多是结果状语从句。
