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?

这是规定,记住了,就可以了

现在完成时要求：助动词 have/has + 现在分词。 lived 在句子中是现在分词，（完成时的）疑问句把助动词 has 提前，形成倒装，而现在分词没有变化。明白了吗？

亲，还需要解答么？
英语中疑问句中就是把助动词提前，前两句的助动词是do,而根据具体语法来讲，一般现在时第三人称单数助动词用does，后面动词用原形。一般过去时的第三人称单数助动词用did，动词也是要用原形。
而完成时的助动词就是has或者have了，具体看单复数了。完成时的形式就是要have/has+过去分词，所以完成时的疑问句里动词还是要用过去分词。
谢谢~...
