　　2015年职称英语考试综合类语法(30)

　　3)如果“have”作“有”讲,也可以在它后面加not构成否定式,其形式与have got的否定式相同。 如：I haven’t (got) any brothers or sisters.(我没有兄弟姐妹)

　　have 的否定形式：

　　当表示“有”的意思时，可以采用以下三种形式：have+not;do not+ have; have+ no+ n. 如：I have not enough food to eat.= I do not have enough food to eat. =I have no enough food to eat.

　　当have为助动词时，用“have+ not”结构。如：I have not been toShanghai。

　　当have既不表示“有”，也不作助动词用时，用“do not+ have”结构。I didn’t have breakfast this morning.

　　具体到反义疑问句中，则遵循以下原则：

　　a.当have表示“有”含义时，反意疑部问部分可以用have形式，也可以用do形式。例如： He has a book in his hand, hasn't he? He has a book in his hand, doesn't he? b.当陈述部分的动词是have“有”的否定形式时，反意疑问部分是用have形式还是用do形式，取决于陈述部分的动词形式。例如： You haven't a car, have you? You don't have any money with you, do you? c.当have不表示“有”含义而表示其他含义时，反意疑问句则必须用do的形式。例如： We had a good time in the vacation, didn't we? He has his breakfast at seven everyday, doesn't he? You have to get up early tomorrow, don't you?
