陳述句和一般疑問句
1. 動詞be的疑問式:動詞be根據(jù)不同的時態(tài)和人稱可以有am, is, are, was, were等不同形式,可用作連系動詞(表示“是”、“在”等)和助動詞(用于構(gòu)成進行時態(tài)和被動語態(tài)等),但不管何種情況,構(gòu)成疑問式時,一律將動詞be的適當(dāng)形式置于句首:
He was late for school. → Was he late for school? 他上學(xué)遲到了嗎?
2. 動詞have的疑問式:動詞have根據(jù)不同的時態(tài)和人稱可以有have, has, had等形式,可以用作實意動詞和助動詞,分以下情況討論:
① 用作實意動詞表示狀態(tài),如表示擁有、患病或用于have to表示“必須”等,在構(gòu)成構(gòu)成式時可以直接將have, has, had置于句首,也可根據(jù)情況在句首使用do, does, did:
He has anything to say. → Does he have [Has he] anything to say?
② 用作實意動詞表示動作,如表示“吃(=eat)”、“喝(=drink)”、“拿(=take)”、“收到(=receive)”、“度過(=spend)”等,構(gòu)成疑問式時不能將have提前至句首,而應(yīng)在句首使用do, does, did:
He has breakfast at home. → Does he have breakfast at home?
③ 用作助動詞構(gòu)成完成時態(tài),其疑問式總是將have等置于句首:
He left when you arrive.→ Has he left when you arrived?
3. 情態(tài)動詞的疑問式:情態(tài)動詞的疑問式通常是將情態(tài)動詞置于句首:

4. 實意動詞的疑問式:一般實意動詞的疑問式,通常應(yīng)根據(jù)不同時態(tài)和人稱在句首加助動詞do, does, did等:
The boy likes dancing.→ Does the boy like dancing?
