结合这几道题具体分析,
如何具体区分do与be动词(am,is,are)再疑问句中的用法?疑问句的疑问词什么时候用do动词,be动词?例如
你只要记住do的用法
第一,do做实义动词,他有实际意思的,表示“做”,比如do sports,做运动
第二,do做助词,没什么实际意思,
1.______Emily at her aunt’s last night?
A.Is B.Was C.Do D.Did
【B】 这里用系动词,因为do作助动词,后面应有动词原形.
2.“Look at my watch!Isn’t is beautiful?” “Yes.Where ____ you ____ it?”
A.do; buy B.were; buy
C.did; buy D.are; buy
【C】 do 作助动词,+动词原形buy
3._______ you with your family yesterday evening?
A.Did B.Was C.Were D.Do
【C】
再问: 如何具体区分do与be动词(am,is,are)再疑问句中的用法?疑问句的疑问词什么时候用do动词,be动词?
再答: 如果陈述句是BE动词的提问时就相应的用BE动词,如果陈述句不是BE东西疑问句就用助动词。 下面举个例子:陈述句:He is reading. 我变成疑问句是就为Is he reading?? 如果陈述句为 he like my book very much.疑问句就是Does he like my book?? 特殊疑问句就是以疑问词开头,对句中某一特定成分提问的句子叫特殊疑问句。常 用的疑问词有:what who whose which when where how why等。下 面还是举个例子:陈述句:Restaurant is over there 如果对地点进行提问疑问句就是Where's the restaurant﹖ 再举个列子 This is my book.对人物提问疑问句就是Whose book is this??
再问: 在具体做疑问句题中如何选填do与be动词(am,is,are)?
再答: 看有无其他动词原型,有就选do,没有就选be(am,is,are) 如这句1.______Emily at her aunt’s last night?没有动词,选be A. Is B. Was C. Do D. Did 2.“Look at my watch! Isn’t is beautiful?” “Yes. Where ____ you ____ it?” A. do; buy B. were; buy C. did; buy D. are; buy 这句有动词原型buy ,就选do
再问: 为什么有动词原形就不能用be动词呢?谢谢
再答: be 后面跟动词有两种形式 be+ving 表示正在进行时 be+ved 表示被动语态 没有be+原型的
