育才学习网1. 如何写定语从句
举个例子：
以定语从句的形式合并这两句The factory lies in the west of the city. His father has ever worked there.
定语从句，就是两句话合成一句话。第一句话中有个the factory，第二句话中有there 但这个there 所指的就是the factory.照答案的意思就是将句子改成意思为“这个我爸爸曾工作过的工厂坐落在城市的西边”，所以可以定下先行词，就是the factory。在此，我想说一句在难度不大的句子中，必须先找到先行词，一般来说，先行词比较好找，你可以翻译两句话的意思，再考虑这两句话的相同处。把你的句子作为例句吧。第一句：这个工厂坐落在城市的西边。第二句，我爸爸曾在这里（这个工厂）工作。两句话的相同处为工厂，那么可以确定先行词为the factory.。（也可以找两句话中相同的词，不过不太实用，像对于你的这个例子就不实用）那么第一句话不变，我们把第二句话话原是先行词（The factory）的部分去掉（就是把第二句的there去掉），然后，把修改过的第二句话移到第一句话的先行词后，并在第一句话的先行词后加上一个合适的关系代词（如that which where who why 等），那么就是【先行词+ 关系代词+定语从句（也就是修改后的第二句话）】当然，修改后的第二句话之后还要跟上第一句话的剩海锭奋瓜莪盖烽睡甫精下部分，这样一个基本的定语从句就完成了。
接下来是关于选择合适的关系代词的问题。我们要考虑先行词在定语从句中的成分。在例句中，也就是找出the factory 在第二句话中所做的成分。因为有there ，这很好判断，就是地点状语，所以，关系代词只能用where。这样就可以确定关系代词了。
当先行词在定语从句中充当地点状语，那么关系代词是用where
若为时间状语，用when；原因状语，用why;
当先行词是人且先行词在定语从句中做主语，关系代词可用who that
当先行词是人且在定语从句中做宾语，关系代词：who that whom或省略不用
还有情况，就是关系代词只能用that 、which 、whom 、who、why、when、where的情况，因为太长，而且，我想你还没遇到，等遇到了，有问题，我再告诉你。我很乐意帮助你。
2. 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 is no one common type of life in America.The reason why so many people died there is that there were not enough food supplies.It looks as if successful international cultural communication will make the world smaller.4.同位语从句 同位语从句用于对前面出现的名词作进一步说明，一般用连词that引导，由于先行名词的意义不同，也可用whether,who,when,where,what,why,how等引导。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。
She finally made the decision that she would join the fashion show.I had no idea how many books I could borrow at a time.The news came that their team had won the championship.5.定语从句 定语从句所修饰的先行词可以是名词或代词，也可以是一个句子。定语从句通常位于先行词之后，由关系代词或关系副词引导。
*限制性定语从句 限制性定语从句修饰先行词，对先行词起修饰作用，紧接先行词之后，无逗号，若省去，原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。
who,whom,whose用于指人，whose有时也可指物，相当于of which;which用于指物；that既可指人也可指物，但只用于限制性定语从句中。关系代词除了引导定语从句，替代先行词外，还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.Those who live alone or who are sick may have trouble in getting close to other people.The girl whose parents died in an accident is living with her grandmother.1）当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时，只能用关系代词that引导从句。That is all that I've heard from him.He's the first person that I'm going to interview this afternoon.2）关系代词的省略 在从句中作宾语的关系代词常可省略。
关系代词紧跟介词，作介词宾语时不可用that，只可用which或whom引导从句，并且不可省略，但当介词位于宾语从句句末时，作为介词宾语的关系代词仍可用that，也可省略。This is one of those things with which we have to put up.This is one of those things (which\that) we have to put up with.3）引导定语从句的关系副词有when,where,why等。
关系副词在从句中作状语，意义上相当于一个“介词+which”的结构。Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.No one knows the reason why(=for which) he was so angry that day.*非限制性定语从句 非限制性定语从句既可修饰先行词，也可修饰整个主句，起补充说明作用，与主句之间有逗号隔开，若省去，原句意思不受影响。
不可用that引导非限制性定语从句。关系词不可省略。
Every object has a gravitational pull,which is rather like magnetism.*“介词+which\。
3. 定语从句怎么写
定语从句是指用一个句子去修饰另外一个句子里的名词或代词。所以你先写好一个句子，如：
I like books. 然后再写一个句子来修饰这个句子里的名词或代词。本句中可以修饰books。另外要注意的是引导词。因为books是物体，所以用that或者which来指代books，也就是说在定语从句中that或which就等于books。那我们就可以这样写：I like books that are in the library.不知道你懂了没有。再比如：The person(who is in the car) is our English teacher.
4. 英语中,从句里面有从句
What I know about the man who you told me yesterday is that he has just retired from factory that/which I visited two days ago.
其中What I know about the man who you told me yesterday是主语从句，从句中who you told me yesterday是定语从句，先行词是the man.
that he has just retired from factory that/which I visited two days ago是表语从句，表语从句中that/which I visited two days ago是定语从句，先行词是the factory.
当然，这是编的.可以根据实际情况而用相应的从句.
5. 英语中宾语从句怎么写
注意：1.从句语序用陈述（主语用在谓语前） 2.连词的选择（陈述句用that ；一般疑问句用if/whether ；特殊疑问句用特殊疑问词） 3.主从句时态一致：1）主句现在时，从句时态不变；2）主句过去时，从句常变为过去某种时态；但是如果从句是一个客观的真理或事实仍用一般现在时。4.代词主句和从句要一致。
I wonder if you can help me with my homework .
Can you tell us when the school festival is ?
