Ted is going to his cousin's house for vacation对 going to his cousin's house提问
问题描述:
Ted is going to his cousin's house for vacation对 going to his cousin's house提问
为什么是what is Ted doing for vacation 不是where is Ted going for vacation
答
如果是对his cousin's house 提问,无疑是用where来提问;
如果是对going to ...提问,则须用what...,因为是在对动作提问;
如果是对vocation提问,则用why,询问去his cousin's house的目的.
希望可以帮到你.
