初中英语语法总结连词连词是一种虚词， 它不能独立担任句子成分而只起连接词与词，短语与短语以及句与句的作用。连词主要可分为两类：并列连词和从属连词。 并列连词并列连词用来连接平行的词、词组和分句。第一类表示并列关系的连词1)and 和判断改错：(错) They sat down and talk about something. (错) They started to dance and sang.(错) I saw two men sitting behind and whisper there.(对) They sat down and talked about something.(对) They started to dance and sing.(对)I saw two men sitting behind and whispering there.解析： 第一句： and 连接两个并列的谓语，所以 talk 应改为 talked
