| 主句 | 关系词 | 定语从句 |
|---|---|---|
| This is the most difficult thing | that (如果关系词在从句中做宾语, 关系词可以省略, 所以 I 前的which 被省略) | I have ever done. |
| This is the most terrible news | I have ever heard. |
功能:用一个句子做定语,定义、修饰名词。
位置:根据英文的“理让弱小”原则,谁短谁放前面,定语是一个句子,短不了,必须放到被修饰名词的后面。
| 被修饰的名词 | 连接词 | 修饰定语 |
|---|---|---|
| This is the job | which | I have dreamed of |
| 先行词 | 关系词 | 定语从句 |
| 简单句 | 定语从句 |
|
|---|---|---|
| This is the job. I have dreamed of the job for years. | This is the job which I have dreamed of | |
| This is A. I have dreamed of B for years. A = B | This is A + C + I have dreamed of |
定语从句与宾语从句不一样,宾语从句是缺什么选择什么关系词,而定语从句,只需要看先行词即可;
| 先行词 | 关系词 | 用法 | 示例 |
|---|---|---|---|
| 事/物 | which 哪个 | 非限制性 | The book, which is on the table, belongs to me. |
| that 那个 | 限制性和非限制性 | The car that is parked outside is mine. | |
| 人 | that 那个 | I have a friend that speaks English. | |
| who 谁 | 非限制性 | Linda, who is my best friend, is coming over for dinner. | |
| whom 谁(可省) | 非限制性,在从句中作宾语。 | The man, whom I met at the party, is a famous actor. | |
| 人/物 某人的\某物的 | whose谁的 | 限制性和非限制性 | The house, whose roof is red, is for sale. |
| 地点 | where 哪儿 | 非限制性 | I visited the school where my mother works. |
| 时间 | when 什么时候 | I still remember the day when we first met. | |
| 原因 | why 为什么 | That's the reason why I didn't go to the party. | |
| |||
定语从句像形容词一样可以形容人、物及事件。分为限定性从句和非限定性关系从句(带逗号,如我的爸、妈、爷、奶是固定且唯一的)。
| 限制性定语从句 对先行词起修饰和限制作用的从句,去掉它将导致句子意义不完整或发生歧义 | 非限制性定语从句 对先行词起补充说明或附加信息的从句,即使去掉也不会影响句子的完整性和主要意义 |
