为什么不能选择a？

老师答疑

龙老师：

此题答案应是d，即选lost，此处属于用过去分词表示状态，可用并列句来改写。又如：

She was staring out over the lake, lost in contemplation.  她凝视湖面，陷入沉思。（= She was staring out over the lake, and she was lost in contemplation.）

He hid his face in his hands again, lost in his own thoughts. 他又用双手捂住脸，陷入了沉思。(=He hid his face in his hands again, and he was lost in his own thoughts.)

She was silent for a while, lost in thought, staring at the books littering the room.  一时间她默不作声，直想得入了神，双眼直愣愣地盯着房间里扔得到处都是的书。(=She was silent for a while, and she was lost in thought, staring at the books littering the room.)

之所以不用being lost，因为现在分词的被动式表示一个正在进行的动作，与句意不符（句子的意思是表示状态）。
