问题 Anna was reading a piece of science fiction, completely ______ to the outside world.

选项 A、having been lost
B、to be lost
C、losing
D、lost

答案 D

解析 本题考查分词作状语。lost是lose的过去分词,可以直接作状语,表示伴随状态,前面无须接 have,故排除A 。B 表示将来的状态,与题意不符。lose是及物动词,后接宾语无需加to,故排除C 。lost与to构成短语be lost to,意为“对…无动于衷”,作状语时,可以省be,故答案为D 。
