高一英语语法定语从句归纳总结

高一英语定语从句的归纳

一．几个基本概念

1.定语从句的定义：用作定语的从句叫定语从句。

2.先行词：被定语从句所修饰的名词或代词。

3.定语从句的位置：紧跟先行词（名词或代词）之后。

4.引导词：引导定语从句的词（包括关系代词和关系副词）。

﹙1﹚关系代词：that/who/whom/which/as

﹙2﹚关系副词：when/where/why

5.引导词的位置：位于定语从句之前（先行词之后）。【as除外】

6.引导词的功能（作用）：

*

﹙1﹚连接先行词和定语从句。

﹙2﹚在定语从句中充当一定的成分（关系代词充当主语或宾语，关系副词充当状语）。7.定语从句的类型：

﹙1﹚限定性定语从句（主句和定语从句之间无逗号）。

①直接由引导词引导定语从句

The man who you’re talking to is my friend.

②由介词+关系代词（whom/which）引导

The man to whom you’re talking is my friend.

~

I need a pen with which I can write a letter.

=I need a piece of paper on which I can write a letter.

介词的选用可根据从句中的相关词组确定，该介词通常可以放在关系代词之前，也可放在从句之尾。例如：

The man (who/whom/that) I talked about at the meeting is from Beijing University.

=The man about whom I talked at the meeting is from Beijing University.

The palace (which/that) I often pay a visit to was built in the 17th century.

=The palace to which I often pay a visit was built in the 17th century.

﹙2﹚非限定性定语从句（主句和定语从句之间用逗号隔开）。

）

①直接由引导词引导定语从句。

②由介词+关系代词（whom/which）引导。

I live in a house far away from the city, in front of which is a big tree.

There is an apple tree standing at the gate, on which are many apples.

This is the man to whom I gave the book.

③由“代词/名词+of+whom/which”或“of which/ whom +名词/代词”(先行词指

人用whom,指物用which)引导。One, some, any, none, all, both, several, many, most, neither,

either等词、数词、分数或百分比与of whom或of which连用。

、

He has five children, two of whom are abroad.

(比较：He has five children, and two of them are abroad.)

We have three books, none of which is/are interesting.

(比较：We have three books, but none of them is/are interesting.)

除why和that不能引导非限定性定语从句外，其余引导词都可以，用法同限定性定语从句一样。但要注意以下区别。

1.在形式上非限定性定语从句与主句有逗号隔开。

2.非限定性定语从句的作用：它只是补充说明先行词的情况，翻译时可译成两个句子。The engineer, whose leg was badly hurt, was quickly sent to hospital.

（那位工程师被很快送往医院，其腿部受了重伤）

The engineer whose leg was badly hurt was quickly sent to hospital.

]

（那位腿部受了重伤的工程师被很快送往医院）

3.在非限定性定语从句中，任何引导词都不能省略（包括引导词在此定语从句中充当宾语在内）。指人做主语时只能用who, 做宾语时用whom;

指物做主语，宾语都用which; 关系副词用when或where，也不能省略。

The man, ______ is sitting on the chair, is my father.

The woman, _______ I met yesterday, is my English teacher.

The city, _______ is far away, is very beautiful.

He went to America, ______ his parents live.

He joined the Army yesterday, ______ I left, too.

引导非限定性定语从句：

The house, whose window faces south, is mine.

》

=The house, the window of which faces south, is mine.

＝The house, of which the window faces south, is mine.

二.定语从句中关系代词和关系副词的基本用法。

that指人是主格在定语从句中代替先行词，又作定语从句的主语，不能省略。

Do you know the gentleman who/that is sitting there

who/that指人是宾格，在定语从句中代替先行词，又作定语从句的宾语（动宾或介宾）。

①当作动宾（动词后接宾语）时，关系代词可省略。

Do you know the gentleman (whom/who/that) we met just now

②当作介宾（介词后接宾语）时：

<

介词不提前时，关系代词可省略；

介词提前时，关系代词不可省，即介词＋whom(指人时介词后的关系代词只能用whom)。The man (whom/who/that) I spoke with is my teacher.

The man with whom I spoke is my teacher.

※注：固定的动词短语（动词+介词）如look for, take care of等不能把动词与介词拆开，既介词不能提至引导词前。

She is the right girl (who/whom/that) we are looking for.
