3)如果“have”作“有”講,也可以在它后面加not構(gòu)成否定式,其形式與have got的否定式相同。 如：I haven’t (got) any brothers or sisters.(我沒(méi)有兄弟姐妹)
    have 的否定形式：
    當(dāng)表示“有”的意思時(shí)，可以采用以下三種形式：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.
    當(dāng)have為助動(dòng)詞時(shí)，用“have+ not”結(jié)構(gòu)。如：I have not been toShanghai。
    當(dāng)have既不表示“有”，也不作助動(dòng)詞用時(shí)，用“do not+ have”結(jié)構(gòu)。I didn’t have breakfast this morning.
    具體到反義疑問(wèn)句中，則遵循以下原則：
    a.當(dāng)have表示“有”含義時(shí)，反意疑部問(wèn)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.當(dāng)陳述部分的動(dòng)詞是have“有”的否定形式時(shí)，反意疑問(wèn)部分是用have形式還是用do形式，取決于陳述部分的動(dòng)詞形式。例如： You haven't a car, have you? You don't have any money with you, do you? c.當(dāng)have不表示“有”含義而表示其他含義時(shí)，反意疑問(wèn)句則必須用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?
