什么时候用do_什么时候用does什么时候用do

do 可以作为助动词,和主要动词一起连用,构成否定、疑问等。如:I like music. -- I don't like music. Do you like music?do 还可以作为实义动词,“做”的意思,用法跟其他实义动词一样。I do my homework everyday.
do的用法 1) 构成一般疑问句,例如: Do you want to pass the CET? 你想通过大学英语测试吗? Did you study German? 你们学过德语吗?2) do + not 构成否定句,例如: I do not want to be criticized. 我不想挨批评。 He doesn't like to study. 他不想学习。 In the past, many students did not know the importance of English. 过去,好多学生不知道英语的重要性。3) 构成否定祈使句,例如: Don't go there. 不要去那里。 Don't be so absent-minded. 不要这么心不在焉。说明: 构成否定祈使句只用do,不用did和does。4) 放在动词原形前,加强该动词的语气,例如: Do come to my birthday party. 一定来参加我的生日宴会。 I did go there. 我确实去那儿了。 I do miss you. 我确实想你。5) 用于倒装句,例如: Never did I hear of such a thing. 我从未听说过这样的事情。 Only when we begin our college life do we realize the importance of English.只有在开始大学生活时我们才认识到英语的重要性。说明: 引导此类倒装句的副词有never, seldom, rarely, little, only, so, well等。6) 用作代动词,例如: ---- Do you like Beijing? --你喜欢北京吗? ---- Yes, I do. --是的,喜欢。(do用作代动词,代替like Beijing.) He knows how to drive a car, doesn't he? 他知道如何开车,对吧?
