答案C
分析：句意是“请来和我们一起吃饭.”and(和)此处并列两个动词.come and have＝come to have(延伸)1)and是并列连词,可以连接词与词(词性相同),短语与 短语,句与句,表示“和”“同”的意思.2)Our country is becoming more and more beautiful．(越来越美丽)3)He thought and thought．(想了又想)4)We waited for hours and hours．(好几个小时)5)注意口语中在come,go,stop后面跟and的用法,如：goand buy some bread＝go to buy some bread：stop and think＝stop to think
