文法 – 形容詞子句 – 特殊關係代名詞 (12)

假如先行詞不是一個名詞，而是一個子句。那一種關係代名詞可以修飾或形容一個子句？答案是which與as。

關係代名詞which與as修飾或形容一個子句：

1.   He is a nice guy, which was mentioned before.

      (which是關係子句的主詞)

      = He is a nice guy, as was mentioned before.

      = He is a nice guy, as mentioned before. (省略was)

      = He is a nice guy, which mentioned before. (X) 不能省略was

      = As was mentioned before, he is a nice guy.

      = As mentioned before, he is a nice guy. (省略was)

      = Which was mentioned before, he is a nice guy. (X)

which引導的關係子句不能放在主要子句的前面

2.   The sun rises in the east, as everyone knows.

      (as是knows的受詞)

      = The sun rises in the east, which everyone knows.

      = As everyone knows, the sun rises in the east.

      = Which everyone knows, the sun rises in the east. (X)

      which引導的關係子句不能放在主要子句的前面

說明：

1)   which引導的關係子句不能放在主要子句的前面。

2)   使用[ as + be + p.p. ]時，可省略[ be ]。
