什麽叫連接副詞,連接副詞的分類
一、連接副詞的分類
連接副詞可分爲兩類,一類是用於連接句子或從句,常見的有therefore, besides, otherwise, however, moreover, still, thus, meanwhile等;另一類是用於引導從句或不定式,主要的有when, why, where, how 等。
二、連接句子或從句的連接副詞
連接副詞的性質類似於竝列連詞,使用時其前通常用分號或句號;若其前用逗號,則通常帶有竝列連詞(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)後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於句中或句末:
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。
三、引導從句和不定式的連接副詞
用於引導從句(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. 告訴我什麽時候離開。
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. 到哪裡去弄到這筆錢正是我們頭痛的事。
That's why he speaks English so well. 那就是他爲什麽英語講得這麽好的原因。
注:連接副詞why 後不能不定式,如可說 I don't know why I must leave.(我不知道我爲什麽必須離開),但不能說 I don't know why to leave。
