A. Do you suppose what has happened to him B. Do you suppose what he has happened C. What do you suppose he has happened D. What do you suppose has happened to him
答案D 考查宾语从句的用法。do you think /believe /expect /suppose在句中作插入语，后接特殊疑问词引导的宾语从句时，要将特殊疑问词放在从句句首。如：Who do you suppose is at home？你猜谁在家？由句意“你猜他发生了什么事”，可知D项正确。sth happen to sb是固定搭配，指“某人发生某事”。 查看原帖>>
