实义动词
除了 助动词 和 情态助动词 以外的，都是实义动词
助动词
助动词不具备语义，不能单独作为句子谓语，必须和实义动词连用
构成各种时态、语态、语气、否定和疑问
be，do，have既可以作为系动词也可以作为助动词
be：am，is，are，was，were，been，being
do：does，did
have：has，had，having
| 助动词 | 功能 | 案例 |
|---|---|---|
| be | 进行时 | I'm studying grammar |
| 被动语态 | I was cheated | |
| do | 帮助实义动词构成否定 | I don't like english |
| 帮助实义动词构成疑问 | Do you like english? | |
| have | 构成完成时 | I have studied english for 3 years |
情态助动词
用来表示可能、建议、愿望、必要、允许、能力、怀疑等，表示说话者对某种行为或者状态的看法和态度
can/could，may/might，must，shall/shoud，will/would
have to，ought to，used to，need/dare
陈述语句否定
谓语动词含有be动词或者情态动词，在其后直接加not
He is teacher. -> He is not teacher.

谓语动词是实义动词，借助于do+not构成
