一、定语从句的定义

在句子中起定语作用的从句,用于修饰、限定先行词(名词或代词)。

例句:

·The friend whom I often play basketball with is moving to another city. 那个我经常一起打篮球的朋友要搬到另一个城市去了。

·The final exam which/that will be held next week makes everyone nervous. 下周将要举行的期末考试让每个人都紧张。

简单句合并示例

二、定语从句的基本结构

核心结构:先行词 + 引导词 + 定语从句

·先行词:位于引导词前,被从句所修饰的名词或代词。

·引导词:分为关系代词关系副词两类,连接先行词和定语从句,同时在从句中充当句子成分。

例句:

·A doctor is a person who looks after a patient. 医生是照顾病人的人。

·Nobody knows the reason why he didn’t come to the meeting. 没人知道她不来开会的原因。

三、定语从句的引导词

(一)关系代词

常见的关系代词:that, which, who, whom, whose,在从句中可充当主语、宾语、表语、定语。

1. which

·用法:代替前面的先行词,先行词只能是,可在从句中作主语、表语、宾语。

·例句:I like the picture which Steve gave you. 我喜欢史蒂夫给你的那张照片。

2. who

·用法:只代替,可在从句中作主语、表语、宾语成分。

·例句:The boy who is playing basketball is David. 正在打篮球的那个男生是大卫。

3. whom

·用法:在定语从句中充当宾语(动词宾语或介词宾语),只代替

·作动词宾语例句:

oThe lady whom we met yesterday is a famous writer. 我们昨天遇见的那位女士是位著名作家。

oHe is the man whom I want to recommend for the job. 他就是我想推荐做这份工作的人。

·注意:作动词宾语时,whom 常常被省略,或用 who 和 that 代替(口语和非正式文体中)。

4. whom 作介词宾语的两种情况

·情况 A:介词前置:将介词提前,放在关系代词 whom 之前。必须且只能使用 whom

例句:

oThe girl to whom you are talking is my cousin.

oWe need to find a person on whom we can rely.

·情况 B:介词后置:介词保留在从句中原本的位置。此时,关系代词可以用 whom,更常用 who/that,或直接省略。

例句:

oThe girl who/whom/that/ 省略 you are talking to is my cousin.

oWe need to find a person who/whom/that/ 省略 we can rely on.

5. that

·用法:既可指代,也可指代,可在从句中作主语、表语、宾语。

·例句:

oHe is the man that I met yesterday. 他就是我昨天遇到的那个男人。

oI like the cup that your mother gave you. 我喜欢你妈妈送你的那个杯子。

6. whose

·用法:与名词连用表所属关系,意为 “…… 的”。

·例句:

oThat’s the student whose father is a fireman. 他就是那位爸爸是消防员的学生。

oI live in a room whose window faces south. 我住在一间窗户朝南的房间里。

只能用 that 的特殊情况

在以下情况中,关系代词通常要用 that,而不用 who 或 which:

1.先行词是不定代词时,如:all, much, everything, anything, nothing, little, few, none 等。

例句:

oAll (that) I have is yours. 我所有的一切都是你的。

oMy dog is interested in everything that smells better than I do. 我的狗对所有比我闻起来香的事物都非常感兴趣。

2.先行词被序数词或形容词最高级修饰时。

例句:

oThis is the best movie (that) I have ever seen. 这是我看过的最好的电影。

oThis is the first piece of news (that) I heard today. 这是我今天听到的第一则消息。

3.先行词被 the very, the only, the last 等修饰时。

例句:

oHe is the only person that can help us. 他是唯一能帮我们的人。

oIt was the last meal that I had in Spain. 那是我在西班牙吃的最后一餐。

4.先行词既包括人又包括物时。

例句:He talked about the schools and teachers that he had visited. 他谈论了他参观过的学校和老师们。

(二)关系副词

常见的关系副词:when, why, where,在从句中充当状语,不可省略。

1. when

六、非限定性定语从句(中考核心考点)

3 个核心考点

1.核心考点:关系词 which 和 who 的基本用法

owhich: 指代前面整个句子或一件事(最高频考点)。

例句:He passed the exam, which made his parents happy.

owho: 指代前面的某个人。

例句:Mr. Li, who teaches us English, is very kind.

2.核心标志:逗号与 that 的禁用

o逗号是判断非限定性定语从句的关键标志。

o铁律:非限定性定语从句中绝对不能使用关系词 that。

3.核心能力:识别与理解

o主要题型:在阅读理解和完型填空中准确理解其含义(which 指代整句话是关键)。

o次要题型:在单选中,能够从选项中选出正确的 which 或 who,并排除 that 的干扰。

中考考查要求

中考不要求复杂运用,只要求掌握 which(指代句子)和 who(指代人)的基本用法,并能识别其与限制性定语从句的区别(有逗号,不用 that)。
