Are/Do you nervous?Are/Do you feel nervous?分别选哪个 为什么

问题描述:

Are/Do you nervous?Are/Do you feel nervous?分别选哪个 为什么

Are you nervous?这是"主系表"结构,因此要用系词Are .
Do you feel nervous?feel 为系词,其"一问"要在句首加助动词do/does .为什么要在句首加助动词呢只有be动词,情态动词变一般问句时,是将be动词,情态动词提到句首外, 其余都要在句首加助动词, 一现: Do/Does+主+动词原形?一过: Did ++主+动词原形?如: Did you go to school yesterday ?Does she like English ?
