My dictionary ____.I have looked for it everywhere but still ____it.

问题描述:

My dictionary ____.I have looked for it everywhere but still ____it.
A has lost;don't find B is missing;don't find
C has lost;haven't found D is missing;haven't found
我不明白第一空为什么用进行时,而不用现在完成时,字典不是以经丢了吗?

missing.在这儿不是表示时态,而是一个形容词,表示状态.丢失的.不见了.
