what happened at his house对吗?为什么老师说是what happened to--
求解释
答
前者表达的是在这个房子里发生了什么；而后者是这件房子怎么了?后文说有一个小偷broke into his house 和偷了一个花瓶，那应该是what happened at 还是 waht happened to文章若是主要围绕花瓶展开，则应该是at his house,反之则为to his house.还有什么问题，欢迎询问。这一题是单项选择，Do you know what happened ——his house？Someone broke into his house and stole the vase from his safe。——一种是to，另一种是at选at,因为如果有and，表明主要是说偷了花瓶。
