陈述句:

用来说明一个事实的句子叫陈述句。它有肯定式和否定式两种形式。
▲陈述句的肯定式:He is a middle school student.(他是个中学生)/ I have a hammer in my hand.(我手上有把锤子)/ She teaches us geography.(她教我们地理)/ The new play was good enough and everybody enjoyed it.(新的话剧非常好大家都喜欢)

▲陈述句的否定式:
1)谓语动词如果是be助动词、情态动词时,在它们的后面加“not”。如:My brotheris nota teacher.(我的弟弟不是教师)/ Hedoes not havea cousin.(他没有堂兄弟)/ Iwill not gothere tomorrow.(明天我不去那儿)/ My motheris not cookinga meal in the kitchen.(我母亲现在不在厨房里做饭)/ Youmust not makesuch mistakes again.(你不该再犯类似错误了)/ Wehaven’t discussedthe question yet(我们还没有讨论那个问题呢).
2)谓语动词如果没有上述词语而是其他动词时,须在它的前面加do not(don’t).如:Idon’t knowanything about it.(此事我一无所知)/ Li Mingdoes not feedpigs in the countryside.(李明不在农村养猪)/ Wedidn’t expectto meet her right here.(我们没指望着在这里见到她)/Wedidn’t havea meeting yesterday afternoon.(昨天下午我们没有开会)
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:Ihaven’t (got)any brothers or sisters.(我没有兄弟姐妹)

have 的否定形式:

      1. 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.
      2. 当have为助动词时,用“have+ not”结构。如:I have not been toShanghai。
      3. 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?

[注意]
①句子中如果有allbothvery much/well等词时,用not一般构成部分否定,如果要完全否定,则通常使用none
