连词用法归纳

一、概说

连词是一种虚词，不单独用作句子成分。可分为并列连词和从属连词。

二、并列连词的用法

1. 表转折关系: but, yet, while 等。

③She knows no one but you. “除了，只”，多用于否定句

④He was the last but one to arrive. “倒数第二个”

⑤You can't help but respect them. “不得不”

注意：①for的从句不能位于原因之前。

④because不能和so连用。

3. 表并列关系: and , or , either…or, neither…nor, not only…but (also), both…and, as well as, when(=and just at this time 就在这时)等。

注意and用法：祈使句+ and

注意or用法: ①Hurry up, or you'll be late for school. “否则”

②He must be joking, or else he's mad. “要不然就”

③He was not clever or good-looking. 用于否定句，代替and
