定语和定语从句的区别
概念理解
1. 什么是定语：定语是对名词或代词起修饰、限定作用的成分，它可以是一个词，短语或者句子。如
果是一个句子，则这个句子就是定语从句。
She is a girl. (beautiful是定语，用来修饰名词girl)
I need a （blue是定语，用来限定名词pen）
Will you attend the meeting ? （不定式作后置定语）
I met a stranger （定语从句，用来修饰a stranger）
2. 构成定语从句有三个部分：
1) _：被定语从句所修饰或限定的词
2) _：一个用来引导定语从句的词
练习：请找出以下定语从句的三个部分:
1) The book that I am reading is very interesting
2) I still remember the place where I met her for the first time.
3) They helped the man whose car had broken down.
3. 定语从句的 引导词 有两种： 关系代词： 关系副词: when, where, why;
关系代词引导的定语从句.
1) This is the man 先行词the man 在定语从句中作主语)
2) She is the girl we met yesterday. (先行词the girl在定语从句中作宾语)
3) My partner is a boy mother is a teacher. （先行词a boy在定语从句中充当定语，即“他的/她
的/它的/他们的/它们的”，引导词用whose）
4) The park is near my home is very beautiful. （先行词the park 在定语从句中作主语）
5) The letter I received was from my father.（先行词 the letter 在定语从句中作宾语）
6) We talked about the persons and things （先行词是 the persons and things，既有人又有物，所以只用that引导）
7) He won the first place in the exam, was very surprising. (先行词是前面整个句子)
练习：
1. Do you still remember the chicken farm _______________ we visited three months ago?
2. The room _________________ window faces north is my sister's.
3. He is the boy __________________ helped the blind woman cross the road .
4. Is this the man _______________you saw just now?
5. This is the very book ______________ I want to read.
6. We should everything _____________ is useful to people.
7. Her sister has become a lawyer, ____________ was always her dream.
【注意以下特殊情况】
下列情况只能用that，不能用which
①. 先行词为不定冠词all, few, little, much, everything, nothing 等.
All you have to do is to practice every day. 你所要做的是每天训练。
There isn’t much 没有什么我可以做的。
②. 先行词被序数词或形容词的最高级所修饰时.
The first lesson (我第一次学的课我不会忘记的。

⑤. 当主句以who/ which/ what开头的 等特殊疑问句时,定语从句that 引导.
Who is the man Which of us knows something about physics doesn’t know this ?
⑥. 先行词既有人又有物时。
We talked about the persons and things we could remember.
⑦. time做先行词，前面如果有序数词或 last 来修饰时，定语从句用 that 来引导或省略；如果没有序
数词或 last 来修饰时，既可用 when 也可用that来引导。
This is the last time () I shall give you a lesson.
The first time (此外：
⑧. 不定代词(anyone, someone, everyone, those等 )指人时，通常用who引导，而不用that
Is there anyone knows the answer? (有没有知道这个答案的人呢？)
I admire those are willing to help others. （我欣赏那些乐于助人的人）

关系副词引导的定语从句
关系副词在定语从句中做状语（时间状语，地点状语，原因状语）.
I still remember the day I first came to Beijing. （when = on that day时间状语）
I’ll never forget the time (when = at that time时间状语)
The story reminds me of last year I traveled in Britain. (when = last year时间状语)
2、先行词是地点，且在定语从句中作地点状语（或定语从句是完整句子时），用where引导。
This is the place （where = in this place 地点状语） The factory 地点状语)
3、先行词是原因，且在定语从句中作原因状语（或定语从句是完整句子时），用why引导。
I know the reason for the reason)
The reason 4、特殊情况：先行词如果是stage, point, situation, condition, position, case等，且从句部分是完整句子，此时习惯用where 引导。
Can you think of a situation It’s helpful to put children in a situation they can see themselves differently.
把小孩处于一种（让他们能不同地看待自己的）情景，这他们是有帮助的。

限制性和非限制定语从句
一、 概念讲解：
限制性定语从句 是修饰先行词必不可少的`成分，去掉从句后句子的意义就不能成立或意思不清楚。如：
A plane is a machine that can fly.
非限制性定语从句 只对先行词作进一步的说明，去掉从句后句子仍然可以成立。非限制性定语从句前
一般用逗号将之与主句隔开
如：This note was left by Mary，who was here a moment ago.
1. who 指人，做主语。Yesterday I met Li Ping, seemed to be very busy.
2. whom 指人, 作宾语. He had many friends, 3. whose 指人, 作定语. The Chairman’s daughter, 4. which 指物, 做主语,宾语. His speech, 5. where 指地点, 作状语. Galileo lived in Pisa, there is a tower about 180 feet high.
6. when 指时间, 作状语. He was born in 1937, 7. as引导的定语从句，其先行词通常是一个句子. As we all know, he studies very hard.
as 引导的定语从句可放在主句前,也可放在主句后.在很多情况下已经构成固定搭配.
As we can see，正如我们能看到的,
As is known to all，众所周知
As you know 正如你所知,
As I expected 正如我所预料， As is mentioned above 如上所说 As is reported 正如报道所说 As the saying goes, 正如俗话说， As is often said 正如经常所说，
As is often the case, 这是经常发生的事
as和 which 引导的非限定性定语从句的比较：
1. 非限定性定语从句位于句未，而且as 和which 在从句中作主语、宾语、表语时
可互换。He is a farmer, as/which is clear from his manner.
This elephant is like a snake, anybody can see.
2.which 引导的非限定性定语从句一般放在句未，而as 引导的非限定性定语从句
可放在句未，也可放在句中、句首。 放在句首时不能用which 替换。
Taiwan is part of China, is known to all. （能翻译成“正如…”可用as引导）
Crusoe lost his dog, made him very sad. （不用as，因为没有“正如…”人含义）
we have seen, oceans cover more than 70 percent of the earth. （不能用Which）
二、 介词提前的定语从句（介词+ which/whom）
1 关系代词which, whom在定语从句中作介词的宾语时，从句可有：介词+ whichwhom 引出。
1） Great changes are taking place in the city which they live in .
= Great changes are taking place in the city 2) The film which I’m speaking of is to be shown next week.
= The film
3. This is the teacher whom I’ve learnt a lot from.
= This is the teacher I’ve learnt a lot.
4. The man whom we sent the present to is a doctor of laws.
= The man whom 5. The situation which we had got into was very dangerous.
had got was very dangerous.
6 The policeman whom Mr. Henry is talking with is a friend of mine.
= The police man Mr. Henry is talking is a friend of mine.
