he is doing his homework.就这个句子来说改为一般疑问句用does还是is.does is都用于现在进行时吗
he is doing his homework.就这个句子来说改为一般疑问句用does还是is.does is都用于现在进行时吗
is 用于现在进行时,does 一般现在时的 助动词的单数形式 该为 is he do his homework 望采纳
举例,现在进行时:he is doing his homework now
does: does he do his homework
再问: is he do his homework为什么不是ing形式- -...而且不是说does后面接动词,is后是名词为什么不是dose。一般现在时和进行时的区别是什么。谢谢啊
