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?

is 是 be 的一种形式。常作联系动词,后面接形容词、名词、介词等作表语。如:He is a teacher.She is beautiful.Tom is behind the tree.
