英语各种问句.
问题描述:
英语各种问句.
一般:He speaks Chinese.Does he speak Chinese?
过去:She went to school yesterday.Did she go to school yesterday?
现在完成:He has lived here since 1949.Has he lived here since 1949?
为什么一般、过去的疑问句中动词都改原型,而现在完成时的疑问句中动词不改?
答
其实这个问题就相当于问:为什么我们叫北京首都(du)不叫首都(dou)?明白吗.这就是一种习惯.学英语过程中,少问为什么,多问怎样做.如果非要解释,那么我只能说have/has done 是在一起的.
望采纳
