英语词汇小知识：不定代词详解
不定代词是代词种类中相对复杂的一种，数量较多且很多词意思几乎相同但修饰不同类型的名词，因此学习者们很容易混淆使用，犯低级错误导致不必要的丢分。不定代词在各类考试中都是考查的重点，所以小编这次就为大家带来不定代词的讲解，希望能给各位学习者们提供帮助。
1.定义： 不定代词是不指明代替任何特定名词或形容词的代词。
2.种类：英语中不定代词数量非常多
some（something，somebody，someone，somewhere）
any（anything，anybody，anyone，anywhere）
no（nothing，nobody，no one）
every（everything，everybody，everyone，everywhere）
all，each，both，much，many，（a）little
（a）few，other（s），another，none，one，either， neither
and so on.
3.用法比较：
① some和any：两者都是“一些”的意思，都可和可数名词或不可数名词连用。some一般用于肯定句中或表示请求意义的疑问句；而any则用于否定句、疑问句或条件从句中.
eg.Tom has some picture books
Have you any questions？
Why don’t you bring some flowers?
② few 与 little：few和a few 后接复数名词，而little和a little后接不可数名词。few 和 little表示数量很少或几乎没有，强调“少”，含有否定意义，a few 和 a little 则表示数量虽然少但毕竟还有，强调“有”，含有肯定意义。
eg.He knew few of them.
I have only a few of pens.
He knew little about it.
There is still a little water in the bottle.
③ all, every, each：all 强调整体地考虑总体，every 强调考虑总体中的所有成员(与all很接近,但all通常与复数名词搭配，every通常与单数名词搭配)，each则强调逐个逐个地考虑总体，all和each既可单独使用，也可后接名词，还可后接of短语，而every 后必须接名词，既不能单独使用也不能后接 of 短语，each 指两者或两者以上的“每个”，every指三者或三者以上“每个”。
eg. All of us need to sit down．
Each of us has a book.
Every kid like chocolate.
④ both，neither，either：both指两者，带有肯定意译，neither指两者，带有否定意义,either指两者中的任何一个。
eg. Both of us can speak Chinese.
She can't sing，neither (can) he.
Either of them will help us.
好了以上就是小编为大家带来的不定代词总结归纳，内容是不是非常丰富呢？大家有没有全部记住呢？学习不定代词的重点就在于辨析意思相近的代词，只要能掌握各个词的特点，清楚的区分它们不同的作用和修饰方法，就能慢慢地走上正轨了。
不定代词定语从句
一、不定代词定语从句用法
在限制性定语从句中,当先行词指人时,关系词可用who(作宾语是还可用whom)或that,二者常可互换.
但在下列情况中,用who(m),而不用that：
(1) 当先行词是one,ones,any,few,anyone,anybody,someone,somebody,everyone,
everybody等词时.如：
Is there anyone who can answer this question?
He was among the few who managed to live through the enemy prison camp.
注：在非正式文体中可以说：You’re the one that knows where to go.)
(2) 当先行词是he,they,those,people,person等词时.如：
He who wants to catch fish just not mind getting wet.
Those who are against the proposal put up your hands.
注：在固定结构的谚语或习语中,可用he that….如：
He that promises too much means nothing.
(3) 当先行词有较长的后置定语修饰时.如：
Do you know the writer in blue with thick glasses who is speaking at the meeting?
(4) 在分隔式定语从句中,若先行词指人,为了明确修饰关系,应当用who(m).如：
A new master will came tomorrow who will teach you German.
There’s only one student in the school who/whom I wanted to see.
I was the only person in my office who was invited.
(5) 两个定语从句同时修饰一个指人的先行词,第二个定语从句常用who(m)来引导,如：
She is the only girl I know who can play the guitar.
二、定语从句用法归纳
定语从句由关系代词who、whom、whose、which、what、as和关系副词where、when、why等引导，但须记住：
1.what不能引导定语从句.
2.关系词的分析须考虑它在定语从句中的成分。
一.指人的关系代词有who、whose、whom、that. 试分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. (=The man who/whom that my father shook hands with just now is our headmaster.)注：
A. 指人时有时只用who不宜用that。
1.先行词为one、ones或anyone
(1)The comrade I want to learn from is the one who studies hard and works hard.
(2)Anyone who breaks the law should be punished.
2.先行词为these时
These who are going to Beijing are the best students of our school.
3.在there be 开头的句子中
There is a student who wants to see you.
4.一个句子中带有两个定语从句，其中一个定语从句的关系代词是that，另一个宜用who，以免重复。
The student that won the first prize is the monitor who works hards.
5.在非限制性定语从句中
A。I met a friend of mine in the street, who had just come from Japan.
B.主句以who开头的句子中,只用that,不用who。
二.指物的关系代词有which、whose(=of which)、that. 试分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
注：
A. 介词如果位于作为其宾语的关系代词之前时，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短语动词中的介词不可与动词拆开，在定语从句中其介词不可前置，只能放在其动词之后。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping’s son.
C. 指物时，下列情况下只能用that ，不宜用which。
(1)先行词为不定代词，如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
(2)先行词是序数词或被序数词、修饰时。
The first book that I read last night was an English novel.
(3)先行词是形容词最高级或被最高级修饰时。
This is one of the most interesting films that I have ever seen.
This is the best that can be done now.
(4)如果有两个或两个以上分别表示人和物的先行词时(先行词既有人又有物)，定语从句的关系代词用which和who都不合适，只能用that。
We know nothing about the doctors and the hospitals that you are talking about.
There are sheep and men that can be seen on the hill.
(5)如果先行词被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修饰时。
This is the only book that can be lent to you.
(6)当主句是以which开头的特殊问句时，关系代词只用that。
Which is the dictionary that he used yesterday ?
D.只物时，下列情况下只能用which，不宜用that。
(1)关系代词放在介词之后
This is the factory in which we once worked.
(2)非限制性定语从句中
This is the book, which is written by Lu Xun.
(3)that，Those作主语时
Those which are on the desk are English books.
E.先行词前有such、the same、 as时, 关系代词用as，不用that, 但the same…as…表示同样的, the same…that…表示同一的
He knows as many people as are present at the meeting.
Such people as you refer to are rare nowadays.
三.比较When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定语从句与非限制性定语从句的区别：
限制性定语从句
非限制性定语从句
All the students who study hard have passed.学习努力的学生都考试及格了。(只有努力的及格了，不努力的没及格。) All the students ,who study hard have passed.所有的学生都及格了，他们学习努力。(没有人不及格，这些学生都很努力。)
从句是先行词不可缺少的定语(如去掉，主句意思就不完整或不正确。) 从句是对先行词的附加说明(如去掉，主句意思仍清楚，不受影响。) 与主句关系密切，不用逗号 与主句关系不十分密切，用逗号与主句隔开译为汉语时，从句译在先行词前，与先行词用“的”连接 译为汉语时，从句放在主句后面关系代词that可以代替who、whom(指人)、which(指物) 关系代词不用that,只用who、whom(指人)、which(指物) 关系代词代替宾语时可以省略 关系代词不能省略关系代词as和which
先研究下面两个例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出来，这头象像条蛇。
○2.Tom didn’t pass the physics exam, which made his parents very angry. Tom物理考试不及格，这使得他父亲很生气。
这两个例句中，as和which所代表的都是整个主句所表示的内容。但有两点不同之处：
1. 在形式上as引导的非限制性定语从句可位于主句的后面，也可位于主句的前面;而which引导的非限制性定语从句只能位于主句的后面，不能位于主句的前面。
2. 在意义上，as引导的定语从句和主句的关系一般为一致关系，常译为“正如……”，“就像……”，而which引导的定语从句和主句的关系是因果关系，或which引导的定语从句是对主句的评论。因此，在意思通顺的情况下，which可代替as，而as许多时候不能代替which，如句○2。再如：
1.He was late again, as / which we had expected. =As we had expected, he was late again. 正如我们所料，他又迟到了。/他又迟到了这是我们早就料到的。
2. The street hasn’t been cleared for weeks, which makes it very dirty. 街道好多星期没有打扫了，因此整条街很脏。(不用as)
3.The young man cheated his friend of much money, which was disgraceful. 那年轻人诈骗了他朋友许多钱财，这是不光彩的。(不 用as)
4.He takes exercise everyday, which has done a lot of good to his health. 他每天运动，这对他的身体很有好处。(不用as)
5.As has already been pointed out, English is rather difficult for a foreigner. 正如已经指出的那样，英语对于初学者说，是相当难学的。在such…as…、the same…as…、 as…、 as many…/much as…等结构中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 这样的书对于初学的人来说是太难了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大楼里。
3.He knows as many people as are present at the meeting. 他认识所有到会的人。
4.That day we all got up early as usual. 那天我们和平时一样，都起得很早。
“One of the +复数名词”后面定语从句中谓语单复数情况
如果one of +复数名词这一结构前面带有the only、the very之类的限定语，后面定语从句的谓语动词则要用单数形式，这是因为定语从句在意义上修饰的是而不是那个复数名词。如：
1.He is the only one of the teachers who knows French in our school.( 修饰the only one)
He is one of the teachers who know French in our school.( 修饰the teachers)
2.This is the only one of the rooms that is free now. (修饰the only one)
This is one of the rooms that are free now. (修饰rooms)
as与which引导的定语从句
两者均可引导非限制性定语从句，有时可以互换，但下列情况多用as。
1. 关系代词引导的定语从句居句首时。 As we all know, the earth is round.
2. 当与such或the same连用时，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 当从句和主句语义一致时，用as，反之则用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在从句中作主语时，后面常接行为动词的被动语态，如be known，be said，be reported等，如从句中行为动词是主动语态，一般要用which作主语。
She has been late again, as was expected.
Tom has made great progress, which made us happy.

3.all与both的用法
1) all都，指三者以上。both都，指两者

3) all通常不与可数名词单数连用，如：不说all the book，而说the whole book。

all还可以与一些特殊的单数名词连用，如all China，all the city，all my life，all the way。
