連接副詞的分類:
連接副詞可分為兩類,一類是用于連接句子或從句,常見的有therefore, besides, otherwise, however, moreover, still, thus, meanwhile等;
另一類是用于引導從句或不定式,主要的有when, why, where, how等。
連接句子或從句的連接副詞:
其性質類似于并列連詞,使用時其前通常用分號或句號;若其前用逗號,則通常帶有并列連詞(如and):
如:I don't like it; besides, it's too expensive. 我不喜歡它,而且也太貴了。
We all tried our best; however, we lost the game./ We all tried our best. However, we lost the game. 我們都已盡了最大的努力,不過我們還是輸了。
注意:有的連接副詞(如however等)后通常有逗號與句子的其他成分隔開。另外,有的這類副詞還可位于句中或句末:
如:Peter is our youngest child, and we have three others besides. 彼昨是我們最小的孩子,我們另外還有三個孩子。
He may, however, come later. 不過,他也許一會兒就到。
We all tried out best. We lost the game, however.我 們都已盡了最大的努力,不過我們還是輸了。
引導從句和不定式的連接副詞:
用于引導從句(名詞性從句)或不定式的連接副詞主要有when, why, where, how等:
如:Tell me when we shall leave./ Tell me when to leave. 告訴我什么時候離開。
I don't know how I can find him./ I don't know how to find him. 我不知道如何找到他。
Where we can get the money is just our problem./ Where to get the money is just our problem. 到哪里去弄這筆錢正是我們頭痛的事。
That's why he speaks English so well. 那就是他為什么英語講得這么好的原因。
注:連接副詞why后不能接不定式,如可說:I don't know why I must leave. (我不知道我為什么必須離開),但不能說:I don't know why to leave.
