育才学习网1. 英语中的定语从句
定语从句可分为：限定性定语从句和非限定性定语从句。
两者最大的区别在于，限定性的主句和从句是完整的一句话，中间没有标点，而非限定性会用逗号把主句和从句隔开。而非限定性定语从句肯定不会出现引导词“that".在限定性定语从句中：1.“that"仅仅只能起连接句子的作用，不作任何成，没有任何意义。
2.“who"表示的是“谁”，在从句中可以充当主语和表语。 3.“whom"表示的是“谁”，在从句中只能充当宾语。
4.“which" 表示的是“哪一个”，可以指“人”，也可以指“物”。
2. 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。
3. 如何写定语从句
定语从句就是说以一个从句做定语。
（ps，定语就是修饰名词或代词的词，一般来说是形容词做定语，也可以用一个从句）然后做题你就看被修饰的名词或代词是什么This is the muzeum_____ we visited yesterday.这道题中从句修饰的是museum，是一个地点，故用whereThe lady_____was here just now a nurse.这里修饰的是lady，是人物，故用whoShe likes the room_____window faces to the south.这里room是有指向性的，有朝南的窗子是定语，带有挑选的含义，故用whichI still remember the night____I had a wonderful dinner with you.这里修饰的night是某个时间，故用when以此类推哦~whose就是带有某人的意思，前面被修饰的名字肯定有归属性如I'm afraid of the man ______dog is violent。.。
4. 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\。
