His father __________ for ten years.答案上是A为什么不选B,dead不是形容词吗,d His father has been dead for two years为什么用been?been不是表被动吗? His father has been dead for ten years.瞬间动词后不可接一段时间的吗? His grandmother() for three years A.died B.dead C.has been d He alone_care of his mother for ten years after his father d It is ten years since his father dead.同义句.急. 用SICE或FOR填空,1,HIS FATHER HAS BEEN DEAD ----------HE WAS TEN 为什么是he has been dead for 10 years而不是he has dead for 10 years his father has been dead for many years改为现在时 His uncle has lived at for ten years.A.No.103 Heping Road B.
