Question

【题目】Tom was sorry to learn that his grandfather _____ for half an hour when he got to the hospital．

A. had died B. had been dead

C. Died D. has been dead

Answer 1

【答案】B

【解析】根据从句when he got to the hospital中可知，die的动作发生在这之前，即过去的过去；另外，die是短暂性动词，不能和时间段相连。be dead表示状态，可以和时间段相连。句意：Tom赶到医院时被告知他的祖父已经离开半小时了，他非常难过。
