英語連接代詞

什么叫連接代詞？所謂連接代詞，指的是用于引導名詞性從句或不定式的代詞。

1. 引導名詞性從句的連接代詞：比較常見的有 what, which, who, whom, whose, whatever, whoever, whomever, whichever等。如：

It is clear enough what he meant. 他是什么意思很清楚。(what引導主語從句)

Ask him which he wants. 問他要哪一個。(which引導賓語從句)

The problem is who can be put in charge of the work. 問題是誰能來負責此事。(who引導表語從句)

Whoever comes will be welcome. 任何人來都歡迎。(whoever引導主語從句)

Buy whichever is cheapest. 買最便宜的。(whichever引導賓語從句)

I’ll just say whatever comes into my head. 我將想到什么說什么。(whatever引導賓語從句)

2. 連接代詞除用于引導名詞性從句外，有時也可引導不定式。如：

I ask him what to do. 我問他該怎么辦。

Show me what to do. 給我說說該做什么。

Did you ask her which to buy? 你問沒問她該買哪一個?

He doesn’t know whom to believe. 他不知該相信誰。

這類用法通常可視為名詞性從句的省略。如：

I wonder who to invite. =I wonder who I should invite. 我拿不定該邀請誰。
