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?
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.
