【解惑】形容詞子句 #基礎篇
關係子句
- 關代可否省略的時機：
- 可省略：
- (1)關係子句中已有主詞，關代不當主詞時
- (2)關代雖當主詞用，和beV.一起省略
例：I know the girl (whom) you’re talking about. I know the girl (who is) next to you.
- 不可省略：
- (1)關代當主詞用，後接一般動詞
- (2)關代當受詞用，前面有介系詞
例：I know the girl who sings the song well.
- 關代的人稱、數必須和先行詞一致
例：I, who your friend, will help you.
You, who my friend, can understand me.
- 關代的「格」：須看關代在關係子句中的位置而定。如為主詞，則用主格（後接動詞）；如為動詞或介系詞的受詞，則用受格；如為形容詞（…的；後接名詞），則用「所有格」
| 先行詞種類 | 主格 | 所有格 | 受格 |
| 人 | who | whose | whom |
| 事物、動物 | which | whose of which | which |
| 人、事物、動物 | that | ——– | that |

- 先行詞前有 “all, no, every, any, the only, the same, the very” 時
