关系代词的定义

关系代词的类型

1. **主格关系代词**:用来代替从句中的主语。常见的主格关系代词有:whowhichthat
– 例如:The man who is talking is my teacher.(正在说话的那个人是我的老师。)

2. **宾格关系代词**:用来代替从句中的宾语。常见的宾格关系代词有:whomwhichthat

3. **所有格关系代词**:用来表示从句中名词的所有关系。常见的所有格关系代词有:whose

关系代词的用法

关系代词在句子中的用法主要包括以下几种:

1. 引导限定性定语从句

限定性定语从句是对先行词(被修饰的名词或代词)进行限定和修饰的从句,关系代词不可省略。限定性定语从句的作用是使先行词的意义更加明确。

例如:
– The book that you gave me is very interesting.(你给我的那本书非常有趣。)
– The man who called you is my brother.(打电话给你的人是我的兄弟。)

2. 引导非限定性定语从句

非限定性定语从句只是对先行词进行附加说明,先行词的意义已经明确,关系代词可以省略。非限定性定语从句通常用逗号与主句隔开。

例如:
– My father, who is a doctor, works in a hospital.(我的父亲是一名医生,他在一家医院工作。)
– The book, which you gave me, is very interesting.(你给我的那本书非常有趣。)

3. 关系代词的省略

在某些情况下,关系代词可以省略,尤其是在口语中。当关系代词在从句中作宾语时,可以省略。

例如:
– The book (that) I borrowed from the library is very interesting.(我从图书馆借的那本书非常有趣。)
– The girl (whom) you met yesterday is my sister.(你昨天见到的那个女孩是我的妹妹。)

4. 关系代词与介词的搭配

当关系代词在从句中作介词的宾语时,介词可以放在关系代词之前,也可以放在从句的末尾。如果介词放在关系代词之前,关系代词不能省略。

例如:
– The man to whom you were speaking is my uncle. = The man whom you were speaking to is my uncle.(你正在和他说话的那个人是我的叔叔。)
– The house in which we live is very old. = The house which we live in is very old.(我们住的那栋房子非常旧。)

关系代词的特殊用法

在某些特殊情况下,关系代词的使用可能会有所不同。

1. “that” 与其他关系代词的区别

“that” 可以用来代替 “who” 和 “which”,但在以下情况下通常使用 “that”:
– 当先行词是最高级或被 only, any, all, few, little, no, some 等词修饰时。
– 例如:This is the best book that I have ever read.(这是我读过的最好的书。)
– 先行词是人和物的总称。
– 例如:The man and his dog that I saw yesterday are my neighbors.(我昨天见到的那个男人和他的狗是我的邻居。)
– 当先行词既包括人又包括物时。
– 例如:She talked about the people and places that she had visited.(她谈到了她去过的人和地方。)

2. “whose” 的用法

“whose” 作为关系代词时,表示所有关系,可以修饰人或物。

例如:
– The man whose car was stolen is my neighbor.(车被偷的那个人是我的邻居。)
– The house whose roof is red is mine.(那个屋顶是红色的房子是我的。)

3. “whom” 的使用情况

“whom” 主要在正式语体中使用,尤其是在书面语中。当关系代词作动词或介词的宾语时,使用 “whom”。

例如:
– The woman whom you met yesterday is a famous writer.(你昨天见到的那个女人是一位著名作家。)
– The man to whom you were speaking is my uncle.(你在和他说话的那个人是我的叔叔。)
