Hello, everyone! Nice to see you again! 我想告诉你们一件很着急的事情，可是我不知道该怎样说。Can you help me?

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

答案：为D。我的字典丢了，由于没有找到，其影响仍然存在，丢字典的状态仍在持续，应用进行时。至于后面，瞬间动词用于否定式时可用完成时。
