he is late .what __have happened to him?为什么填can?
can be done 在疑问句中不是表示可能已经么？翻译不通呀。

首先,情态动词有很多用法.拿can举例.大家多半知道它的本意是“能,能够”的意思,eg: I can swim, but I can't play football. 我会游泳,但我不会踢足球. 但是can 还有其他用法,即情态动词表示推测, 一般can表示推测用于否定句.eg: That can't be Lily, because she has been in China now.其中can't表示“不可能”,整句意思是那不可能是丽丽,她在中国.但是"can" 也可用于肯定句或疑问句,表示的推测是一种客观的推测,即不是说话者的主观意见.或者表示的是 “有时候会”.eg: Everyone can die.每个人都可能死（人固有一死）.这不是说话人的主观臆断,因为这是自然定律.问题中是can表示推测,而不是“能”的意思.是对过去的推测.就是他可能发生了什么事的意思

I wanted to know_to him.为什么填what happened而不是what has happene what happened to him? he is such a nice man that you can't --- to like him 为什么填fai 为什么：他发生了什么?是what happened to him 而不是what did he happen?那为什么又 She is _____(wonder) what happened to him. what‘s ————to him?He is quite politely today A happened to B 选择 What ___ him just now?He is unhappy.A.happened B.happened what happened with him?what happened with he?哪个对? what happened to him yesterday.为什么要用happened?happen可以吗
