Question

Changchang, the oldest known panda in China, ________ for one month.

1. A.
   has died
2. B.
   has been dead
3. C.
   was dead
4. D.
   died

Answer 1

B
本題的干擾項(xiàng)是選項(xiàng)A。die是表示瞬間動(dòng)作的動(dòng)詞，因此其完成時(shí)不可以與表示一段時(shí)間的狀語(yǔ)連用，因此排除A。而選項(xiàng)B中的has been dead是be dead的完成形式，表示狀態(tài)，是可以和for one month連用的。
