中考英语知识点：表示并列关系的连词

　　并列连词：并列连词用来连接平行的词、词组和分句。

　　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。

　　第二句：and 连接两个并列的动词不定式，第二个不定式往往省略to，因此sang 应改为 sing。

　　第三句：and 连接感观动词saw 后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。

　　注意：1. and 还可以和祈使句或名词词组连用表示条件。(or也有此用法)

　　Make up your mind, and you'll get the chance.

　　= If you make up your mind, you'll get the chance.

　　One more effort, and you'll succeed.

　　= If you make one more effort, you'll succeed

　　2, A and B 当表示整体或者指同一人时谓语动词用单数, 当and连接的单数名词前分别有each，every，many等词修饰时，谓语也用单数。

　　bread and butter a knife and fork
