语法上没错!主语从句改为过去完成时较好,即：That he 【had passed】 the exam 不过更习惯于说： The reason why his parents were pleased was that he had passed the exam 很高兴为您解答,fightout为您答疑解惑 如果本题有什么不明白可以追问, 再问： 所以说，我这样子写是对的咯?我被我们老师骗了，她也有说到“The reason why his parents were pleased was that he had passed the exam ”，但是我个人在听电影之类的时候一般只听到我所写的那种说法，那也只是一点点印象而已。所以我写那个是一定对吧？ 再答： 没错的！！
