问题描述：
Anna was reading a piece of science fiction,completely ___ to the outside world.
Anna was reading a piece of science fiction,completely _D__ to the outside world.
A、having been lost B、 to be lost C、losing D、 lost
为什么不能选C呢,D和C的区别在哪啊?
答
因为题目是过去时态，所以选C。D是进行时态，不符合题目的要求，所以不选。
答
lost表完成,应经完全的沉醉在书里了.losing则表正在迷失,正在与外界失去联系,不符合.
