例: He goes to school by bike.肯定句 He doesn't go to school by bike.否定句 Does he go to school by bike? How does he go to school?特殊疑问句? 你又要用一句话来说明,又要写详细些,这是不可能实现的,除非我写的这句话一直用逗号,不写句号。而且不是三两句话能够说明的。这其中涉及到主语是第几人称、单数还是复数,是实义动词还是系动词。 你可以举几个例子出来。我帮你解答。

he does his homework. he does do his homework. dose he do his homework? (首字母大些) do does did 要根据时态。 be动词is am are was were也是。 疑问句,否定句有some要改成any的 没要点了吧。,。。
