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。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?

原陈述句中,若谓语动词是have / has, 则须考虑have / has的意义。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。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。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 。如(from http://yingyu.chazidian.com):
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。这两个动词既可以做情态动词又可以做行为动词。做情态动词时,直接将它们移到句首。此时,若用need的问句,肯定回答时用must,否定回答时,用needn’t。若作行为动词,则用Do的适当的形式提问。如:
