高中定语从句详细讲解 Part 1 （一）定义及相关术语 1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先 行词之后。 2．先行词：被定语从句修饰的词叫先行词。 3．关系词：引导定语从句的词叫关系词。 关系词有关系代词和关系副词。关系代词有 that, which, who, whom, whose, as 等; 关系副词有 when, where
, why 等。 关系词通常有下列三个作用： A、引导定语从句； B、代替先行词 C、在定语从句中担当一个成分。例如： The man who is shaking hands with my father is a policeman. 该句中，who is shaking hands with my father 是定语从句，修饰先行词 the man， “who”是引 导定语从句的关系词，代替先行词 the man，在定语从句中作主语。 A plane is a machine. The machine can fly. A plane is a machine that can fly. The girl is Mary. We saw her yesterday. The girl we saw yesterday is Mary. （二）关系代词引导的定语从句 1．who 指人，在定语从句中作主语。 The boys who are playing football are from Class One. 正在踢足球的男孩是一班的。 Those who want to go to the museum must be at the school gate at 7 tomorrow morning. 想去博物馆的人必须在明晨 7 点到大门口集合。 Yesterday I helped an old man who had lost his way. 昨天我帮助了一位迷路的老人。 That is the teacher who teaches us physics. 那就是教我们物理的老师。 2．whom 指人，在定语从句中做宾语，常可省略。 Mr Liu is the person ( whom ) you talked about on the bus. 刘先生就是你们在公共汽车上谈论的那个人。 Li Ming is just the boy ( whom ) I want to see. 李明正是我想要见的男孩。 The professor ( whom ) you are waiting for has come. 你正在等的教授已经来了。 The girl ( whom ) the teacher often praises is our monitor. 老师经常表扬的那个女孩是我们的班长。 注意：关系代词 whom 在口语或非正式文体中常可用 who 来代替，也可省略。 The man ( whom / who )you met just now is my old friend. 3．Which 指物，在定语从句中做主语或宾语，做宾语时常可省略。 Football is a game which is liked by most boys. 足球是大多数男孩所喜欢的运动。 The factory which makes computers is far away from here.制造计算机的那家公司离这儿很远。 He likes to read books which are written by foreign writers. 他喜欢外国作家写的书。 The house which is by the lake looks nice. 湖边的那幢房子看上去很漂亮。 This is the pen ( which ) he bought yesterday. 这是他昨天买的钢笔。 The film ( which ) they went to see last night was not interesting at all. 他们昨晚看的电影一点意思也没有。

Do you like the book the cover of which is yellow? （三） “介词+关系代词”引导的定语从句 关系代词在定语从句中作介词宾语时，从句常常由“介词+关系代词”引出。 The school (which / that) he once studied in is very famous. The school in which he once studied is very famous. 他曾经就读过的学校很出名。 Tomorrow I’ll bring here the magazine (which / that) you asked for.

物时只可用 which，不可用 that。关系代词是所有格时用 whose。 The man with whom you talked just now is my neighbour. (正) 你刚才跟他谈话的那个人是我的邻居。 The man with that / who you talked just now is my neighbour. (误) The plane in which we flew to Canada was really comfortable. (正) 我们去加拿大所乘坐的飞机实在很舒服。 The plane in that we flew to Canada was really comfortable.

The man , whom you met yesterday, is my friend. Part 3 考点归纳 ? 考点一：that 与 which 1.只用 that 的情况 Tom is the tallest boy that I have ever know. This is the first play that I have seen since I came here. （1）序数词或形容词最高级修饰先行词时 I have read all the books that you gave me. You can take any room that you like. Nothing that we saw in this film is true. She told everything that she had known.
（ 2 ）当先行词是不定代词或被不定代词修饰时， all,every, any,no,none, few, little, much, everything，nothing，anything 等 This is the very book that I'm looking for. （3）当先行词有 the very, the only 等修饰 Who is the boy that is standing under the tree? Which is the book that we bought last week？ （4）当主句中已有 who/which 时， 避免重复。 I have never heard the people and things that you talked about just now. （5）当先行词同时指人和事时 He is not the man that he was when I first saw him. （6） 关系代词在定语从句中作表语，不管是人或物只能用 that 2. 不能用 that 的情况：关系代词前有介词。 This is the boy with whom he talked. This is the ring on which she spent 1000 dollars. ? 考点二：when, where, why 与 that, which 的区分 I will never forget the day we first met in the park. I will never forget the time we spent with you. This is the reason I didn't came here. The reason she gave was not true. 分析从句谓语动词与先行词之间的逻辑关系, 在从句中作主语宾语，用 that ,which 等，作状 语，用关系副词。
? 考点三：as 的使用 1. as 引导非限制性定语从句 He married her, as was natural. 他跟她结婚了，这是很自然的事。 He married her, which was natural. He is honest, as can be seen. 他很诚实，这一点我们看得出来。 =He is honest, which can be seen. =As can be seen, he is honest. 2.as 引导限制性定语从句 当先行词受 so, such, as, the same 修饰时，关系词常用 as。 如：I’ve never heard such stories as he told. 我从未听过他讲的那些故事。 他可不像他看上去的那样傻。He is not as/so foolish as he looks. This is the same book as I read last week. 这本书跟我上周看的一样。 This is the same book that I read last week. 这本书就是我上周看的那本。 It is so interesting a book we all like. It is so interesting a book we all like it. A. as B. that 区分定语从句和结果状语从句 ? 考点四：定语从句中谓语动词的单复数
He is the only one of the student in our class who He is one of the students in our class who 取决于先行词的单复数
(have) got the teacher's praise.
(have) got the teacher's praise.
? 考点五：the way+in which/that/省略+定语从句 That is not the way ______I do it. A./ B.which C.how D.with which The way ______he looks at problems is wrong. A. which B. how C. what D./ This is the way ____________ he thought of to solve the problem. A. which B.in which C.with which D. How the way+关系词引导定语从句，首先排除用 how。 The way 或 the time 等特殊先行词后面的 that 也可以做状语。 正式语体中， that 可 以用 in which 代替， 口语中省略 that 也可以， 显得更自然。 因此就构成了 the way 在定语从句中做状语的三个结构：the way+in which/that/省略+定语从句。 如果 the way 不做状语，则跟其他先行词一样处理。 ? 考点六：定语从句和同位语从句的区别
The fact that surprised me was true. 定语从句，修饰作用。that 是关系词， 担任成分。 The fact that he died was true. 同位语从句，说明具体内容。that 是连词，不作成分。 考点七：特殊关系代词 but There are very few but admire his talents. 没有几个人不钦羡他的才华。 but= who don’t ? 考点七：关系代词作宾语不可省略的情况 1. 在介词+whom /which 结构中, whom, which 不能省略。 That is the headmaster with whom my father was talking just now. This is the ring on which she spent 1000 dollars. 2.在 the same ... as, such ... as, as ... as, the same... that 结构中, as, that 即使作宾语,也不能省略。 I have bought the same bike as you (have). This is the same film that I watched yesterday. 3. 当 and, but, or 等连词连接两个或两个以上的定语从句修饰一个先行词时,关系代词第一个 可省略,第二、第三个等不可省略。 This is the book (which) I read yesterday and which I found very interesting. 4.在非限制性定语从句中,作宾语的关系代词也不能省略。 Mr Green, whom you know, is the tallest in our school. Smoking is harmful to one's health, as we all know.
