  新东方在线中考网整理了《2020中考英语必须要掌握的知识点:定语从句》,希望对家长和中考生有所帮助。

  1.定语从句的功用和结构

  在复合句中,修饰某一名词或代词的从句叫做定语从句。被定从句修饰的词叫做先行词。定语从句必须放在先行词之后。引导定语从句的关联词有关系代词和关系副词。例如:

  This is the present that he gave me for my birthday

  2.关系代词和关系副词的功用

  关系代词和关系副词用来引导定于从句,在先行词和定语从句之间起纽带作用,使二者联系起来。关系代词和关系副词又在定语从句中充当一个成分。关系待客做主语,宾语,定语,关系副词可作状语。

  1. 作主语:关系代词在定语从句中作主语时,从句的谓语动词的人称和数须和先行词一致。例如:

  I don’t like people who talk much but do little.

  The cars which are produced in Hubei Province sell very well.

  2. 作宾语:She is the person that I met at the school gate yesterday.

  The book that my grandmother gave me is called “The Great Escape”.

  3. 作定语

  关系代词whose在定语从句中作定语用。例如:

  What’s the name of the young man whose sister is a doctor?

  The girl whose father is a teacher studies very hard.

  4. 作状语

  I’ll never forget the day when I first came to Beijing.

  三. 各个关系代词和关系副词的具体用法

  1. who 指人,在定语从句中作主语。例如:

  The person who broke the window must pay for it.

  The boy who is wearing the black jacket is very clever.

  2. whom指人,在定语从句中作宾语。例如:

  Do you know the young man (whom) we met at the gate?

  Mr Lee (whom) you want to see has come.

  3. whose 指人,在定语从句中作定语。例如:

  The girl whose mother is ill is staying at home today.

  I know the boy whose father is a professor.

  4. which指物,在定语从中作主语或宾语。例如:

  A dictionary is a book which gives the meaning of words.

  Here is the book (which) the teacher mentioned yesterday.

  5. that多指物,有时也指人,在定语从句中作主语或宾语。例如:

  I’ve read the newspaper that(which) carries the important news.

  Who is the person that is reading the newspaper over there?

  6. when 指时间,在定语从句中作状语。例如:

  I’ll never forget the time when we worked on the farm.

  He arrived in Beijing on the day when I left.

  7. where 指地点,在定语从句中作状语。例如:

  This is the house where we lived last year.

  The factory where his father works is in the east of the city.

  四. 关系代词 whom, which 在定语从句中作介词宾语时,可以和介词一起放于先行词与定语从句之间,有时为了关系紧凑也可以将 whom 与 which 与先行词紧挨着书写,而将介词置于定语从句的后面,如:

  That was the room in which we had lived for ten years. = That was the room

  which we had lived in for ten years.

  五. 具体使用时还要注意下列问题:

  1. 只能使用that,不用which 的情况:

  (1) 先行词是all, few, little, nothing, everything, anything 等不定代词时。例如:

  All that he said is true.

  (2) 先行词被only, no, any, all,等词修饰时。例如:

  He is the only foreigner that has been to that place.

  (3) 先行词是序数词或被序数词修饰的词。例如:

  He was the second (person) that told me the secret.

  (4) 先行词是形容词最高级或被形容词最高级修饰的词。

  This is the best book (that) I have read this year.

  (5) 先行词既包括人又包括物时。例如:

  He talked about the people and the things he remembered.

  2. 只能用which,不用that 的情况:

  (1) 在非限制性定语从中。例如:

  The meeting was put off, which was exactly what we wanted.

  (2) 定语从句由介词+关系代词引导,先行词是物时。例如:

  The thing about which he is talking is of great importance.

  考查的主要形式是单项填空、完型填空、短文填空和完成句子。阅读理解和书面表达肯定也要用到定语从句。
