has为have的第三人称单数形式，用于不可数名词、可数名词单数或第三人称单数代词作主语的句子中。

2.have /has 作谓语时的句型转换。

(2) 一般疑问句式：
Do/Does + 主语 + have ...?

→I haven't got a computer.
→Have you got a computer ?
4.have/has 的含义相当多，表示“吃、喝”等，还可以构成许多常用的短语，其后跟不同的名词作宾语时，其本身含义也随之发生变化。
have lunch 吃午饭
have a look 看一看
have a glass of milk 喝杯牛奶
have a party 举行晚会
have a good time/have a good day/have
fun 玩得开心
have a rest 休息一下
have to用法have to
表示“不得不”、“必须”。在肯定句中， have to 随人称和时态的不同而变化。其否定式和疑问式 的构成形式与行为动词have相同，即需使用助动词。
e.g 1). It’s too late. I have to walk home.
2). They don’t have to finish the work today.
3). He had to leave early yesterday.
4). Did he have to leave early yesterday?have to 的第三人称单数形式是：
has to
He/ She/ It/Tom/ My father/ has to
have to 和has to 的过去式：had to否定：
have to---- don’t have to
has to --- doesn’t have to
had to --- didn’t have to
都表示 “不必”
must意思为“必须……，得……，要……”；
肯定式：must + V原；
否定式：must + not + V原；
疑问式：Must + 主语……?
e.g 1). You must go home now.
2). You mustn’t smoke here.
3). Must I finish English course this term?由must引起的疑问句，肯定回答要用must或have to,否定回答要用needn’t或don’t have to,意思是“不必”；
must 与have to 的区别
异：♀must多表示主观意志，是从说话人的角度出发谈必 须做某事。而have to强调客观需要。
e.g. A. I must finish my homework today.
B. I have to finish my homework before
lunchtime.
♀二者否定式的意义大不相同。have to 的否定式表示“不必”，而must not/mustn’t表示“不准”。
e.g. A. I don’t have to finish my homework now.
B. You mustn’t arrive late or you’ll get
into trouble.
♀must没有时态变化，而have to 可有不同的时态变化。
e.g. 1).We will have to leave tomorrow.
2).Tom had to finish his work yesterday.
