名词性从句
在句子中起名词作用的句子叫名词从句 (Noun Clauses）.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.
形容词性从句--定语从句
用来修饰名词,代词,句子等,在句中的作用相当于形容词,故称为形容词性从句.
定语从句分为限制性定语从句和非限制性定语从句.
限制性定语从句对被修饰词起到限制,修饰的作用,一般不可缺少.
非限制性定语从句起补充,附带说明作用,缺少也不会影响全句的理解.
e.g.She said she had finished her work,which I doubted very much.
I've got some personal affairs that I have to deal with.
定语从句常用关系词
关系代词:who,whom,whose,that,which,as等(在句中作主,表,宾,定等成分)
关系副词:where(on which),when(in which),why(for which)(在句中作状语)
关联词:that(引导表示方式,时间的定语从句)
e.g.In this earthquake,the number of people who lost homes reached as many as 250,000.
I have many good friends to whom I am going to send postcards.
You're the only person whose advice he might listen to.
The river which runs through the center of the city brings us a lot of pleasure.
He has given us as much advice as he can.
Potato can be grown in places where it is too cold to grow rice.
I don't like the way (that) you treat us.
定语从句引导词的选择
取决于先行词(被修饰词)在定语从句中的位置,成分.
e.g.The people whom\who\that you met in the campus are from Australia.(作宾语)
This was the time when\at which she left for Beijing.
The place which he often visits is always full of artists.
使用要点
1.关系代词在从句中作主语时,不能省略.
e.g.The classroom that is on the fourth floor is poorly equipped.
2.关系代词在从句中作宾语且前面没有介词时,常可省略.
e.g.This is the girl with whom he works.
3.关系副词在定语从句中不可省略.
e.g.I have come to explain the reason why I was absent from the meeting.
4.只用that,不用which的情况:
当先行词有序数词或形容词最高级修饰时;
当先行词前有the only,the very,the last等词修饰时;
当先行词为anything,nothing,something,everything,all,little,much等不定代词修饰时;
当先行词前有all,every,no,some,any,little,much,few等词修饰时;
It is 句型中的引导定语从句时.
5.只用which,不用that的情况:
引导非限制性定语从句时;
引导词前有介词时;
一个句子中若有两个定语从句,一个用that引导,另一个用which引导;
e.g.He bought a book that could give him much knowledge and which could help him to kill the time.
6.当those作为先行词指人时,通常只能用who引导;
as 从句的先行词是the same,such,或被他们所修饰;多用于表示肯定意义的从句中,不用于表否定意义的从句中.
e.g.Many of the sports are the same as they were when they started.
The result was not such as he expected.
It was raining hard,which(as) was unexpected.
8.介词+关系代词要根据
谓语动词的固定搭配 e.g.This is the evidence with which the case is connected.
先行词 e.g.I'll never forget the day on which\when I joined the party.
c.句子表达的意思 e.g.The boss in whose department Mr King worked got sacked.
d.在非限制性定语从句中,名词\代词+of+which\whom表示整体与部分的关系
e.g.The workers,some of whom stayed for four years,came from different countries.
e.介词的位置一般放在关系代词之前,有时也可放在从句中原来的位置上.
e.g.We did it in the same way in which he did\which he did in.
9.That 作为关联词可以当作关系副词用
e.g.This is the house in which Louis XIII lived.
This is the house that Louis XIII lived.
This is the house where Louis XIII lived.
This is house which Louis XIII lived in.
This is the house Louis XIII lived in.
定语从句的使用需注意:
My brother who is very clever studies chemistry all by himself.
使用定语从句勿滥!可以使用单个形容词,或较短的非谓语动词结构的,尽量使用简略些的方式.使句子读起来更顺口!

比如,what did he do made me so angry .这是个名词性从句,what did he do 它是个句子,它在句中充当主语.这个句子的意思是他所做的让我很生气.其中他所做的是指事情,事情是名词,一般地名词或代词充当主语,也充当宾语.所以说名词性从句就是充当主语或宾语中的句子.~~~~~注:本人说得可能有些复杂,但理解了其实很简单的
主语从句主要这三种情况：
⑴由that引导。
That I have a friend like you is great
⑵由what引导
What I know is that he is a teacher.
⑶由连接副词或连接代词引导（when, where, why, how, which, who）
When we will go is not decided .

在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句,包括时间、条件、结果、目的、原因、让步、地点、方式等）。
主语从句用作主语，如：：
That the earth is round is true. 地球为圆的是真实的。
宾语从句用作宾语。如：
Do you know ...

主语从句用作主语，如：：
That the earth is round is true. 地球为圆的是真实的。
宾语从句用作宾语。如：
Do you know where he lives?
表语从句用作表语，如：
My opinion is that you should not go alone. 我的意见是你不应单独前往。
同位语从句用于解释说明前面的名词。如：
The fact that the earth is round is true. 地球是圆的的事实是真实的。（that从句用于解释说明the fact）
定语从句相当于一个形容词，用于修饰前面的名词。如：
The student who answered the question was John. 回答问题的学生是John.
状语从句相当于一个副词，如：
When it rains, I usually go to school by bus. 天下雨时，我通常坐公共汽车上学。（时间状语）
If he comes tomorrow, you will see him. 如果他明天来，你就可以看见他。（if 引导的条件状语从句，其结构为：if +状语从句，＋主句）。要注意在状语从句中有一个规则是“主将从现”，即主句是将来时，则从句要用一般现在时表示将来。
主句和从句的划分方法是相同的。句子的成分从谓语动词处来划分比较容易。谓语动词前面的部分是主语，后面常接宾语，修饰谓语动词的是状语，修饰主语、宾语的是定语，若谓语是系动词，则系动词后的部分是表语。如：
I am a teacher. 其中，I 是主语，am是谓语，a teacher 是表语。
He likes playing football very mucy. 其中，he是主语，likes是谓语，playing
