最近很多小伙伴想了解疑问句怎样改陈述句,疑问句改为陈述句的相关知识,今天小编专门整理了一些相关内容,一起来看看吧。

1、1. 陈述句中有系动词be、助动词be, have / has, do, will, would, shall, should, had或情态动词can, could, may, might, must, dare, need, ought时,将这些系动词、助动词或情态动词移到句首,并在句末加上问号。

2、如:I’ll go to the History Museum this afternoon.— Will you go to the History Museum this afternoon?今天下午你去了历史博物馆吗?I visited Beijing last month.— Did you visit Beijing last month?上个月你参观了北京吗?在对疑问句进行回答时,须注意:(1) 当回答could, would所提的问题时,一般用can, will.如:—Could you help me with my homework this evening?—Yes, I can. / No, I can’t.—Would you go there right now?—Yes, I will. / No, I won’t.在对方向你表示邀请时,可用OK, sorry等来替代Yes,No.(2) 在对用may所提问题的否定回答时,一般用mustn’t / can’t;而在对用 must所提的问题进行否定回答时,一般用needn’t / don’t have to.如:—May I use your bike now?—Yes, you may. / No, you can’t. (mustn’t)—Must I stay at school this afternoon?—Yes, you must. / No, you needn’t (don’t have to).2. 原陈述中没有系动词be、助动词be, have / has, do, will, would, shall, should had或情态动词can, could, may, might, must, dare, need, ought时,则在句首加助动词Do的适当形式,同时,将谓语动词变为原形动词。

3、如:We speak Chinese.— Do you speak Chinese?你讲汉语吗?I went shopping yesterday.—Did you go shopping yesterday?昨天你去买东西了吗?3. 原陈述句中,若谓语动词是have / has, 则须考虑have / has的意义。

4、如果have / has是“有”的意义时,变为疑问句时,既可在句首加Do的适当形式,也可将have / has,提到句首。

5、如:He has a beautiful pen.—Has he a beautiful pen? / does he have a beautiful pen?他有一只漂亮的钢笔吗?但若have / has,的意思不是“有”时,变为疑问句时,则必须在句手加Do的适当形式。

6、如:I have lunch at home.—Do you have lunch at home?你在家吃中饭吗?We had a meeting last night.—Did you have a meeting last night?昨天晚上你开会了吗?原陈述句中有情态动词used to时,它的一般疑问句,可将used移到句首;也可在句首加Did 。

7、如:I used to go swimming in the river.—Did you use to go swimming in the river? / Used you to go swimming in the river?你过去常常去那条河里游泳吗?当心need, dare两个动词。

8、这两个动词既可以做情态动词又可以做行为动词。

9、做情态动词时,直接将它们移到句首。

10、此时,若用need的问句,肯定回答时用must,否定回答时,用needn’t。

11、若作行为动词,则用Do的适当的形式提问。

12、如:—Need I come here tomorrow?—Yes, you must. / No, you needn’t.—I need to go to school now.—Do you need to go to school now?—Dare you tell your father about it?—Do you dare to go out at night?。
