【题目】Anna was reading a piece of science fiction，completely ________to the outside world.
A.having been lostB.to be lostC.losingD.lost
在线课程【答案】D
【解析】
考查非谓语动词。句意：安娜正在读一本科幻小说，完全无视外面的世界。短语be lost to“对……漠然视之，无动于衷，不注意”。lose和主句的主语Anna之间的逻辑关系为Anna was completely lost to the outside world, 因此用形容词化的过去分词作状语。故选D项。
