Anna was reading a piece of science fiction, completely ___ to the outside world.
a. being lost
b. to be lost
c.losing
d. lost
为什么不能选择a?
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)。
