is和does的区别是什么?如:when does your brother do his homework?可不可以说成 when is your brother
如:when does your brother do his homework?可不可以说成 when is your brother do his homework?如果可以,为什么?什么情况下不可以?如果不可以,为什么?什么情况下可以?我最多可以提高悬赏10分,只要讲明白即可
什么情况用does提问?什么时候用is提问?
答
不行,is是be动词,后面只能接名词,形容词,动词不定式to do,ing动词.例如:
he is to study hard .
she is cleaning her room .
does做实义动词是“做”的意思,如,he usually does his does homework afterschool .does做助动词无意义,一般表示强调,he does do the homework.(他真的做了家作) 或在疑问句中与动词原形连用does she do the homework
这应该就是它们的区别,而它们的共同点就是它们都只能用于单数形式,且是现在时.
