Have 有四种用法：表示“拥有”；与描绘动作的名词连用有“进行”的含义，其具体的汉语意思主要由名词决定，如 have a look 瞧一瞧，have a walk 散散步，have a meeting 开会，have supper 吃晚饭，have toothache牙疼，等等；用作助动词，与动词过去分词构成完成时态，表示“已经”；have to连用是作情态动词，表示“只好/不得不”。
除了用作助动词外，have 在口语中常用 have got 代替，如：
He has a computer. / He has got a computer.
I have toothache. / I have got toothache.
They have to leave for Beijing. / They have got to leave for Beijing.
这种用法同样可以用在疑问句和否定句中，如：
Does he have a computer? / Has he got a computer?.
Do you have toothache? / Have you got toothache?
Do they have to leave for Beijing? / Have they got to leave for Beijing?
He doesn’t have a computer. / He hasn’t got a computer.
I don’t have toothache. / I haven’t got toothache.
They don’t have to leave for Beijing. / They haven’t got to leave for Beijing.
另外，英国有英语在表示“拥有”这一概念是可以直接把 have 提前构成疑问句，用haven’t 构成否定句：
Has he any computer?
He hasn’t any computer.
have用法吗①have可以作为
，本身无词义，主要用于构成各种时态、
、语气以及否定和疑问结构。（那此时的have还是has就要看具体的人称而定）
②have也能作为实义词，解释为“有”，用于疑问句和否定句时要用
do。
问题He doesnt have any coffee.
就是第二种：他没有咖啡。为否定句，用
do的
形式does。在这样的助动词后面一定要用
have。
不是
表示“有”否定形式有误，第一个应该是
He hasn't got a computer.
He doesn't have a computer
