My dictionary. I have looked for it everywhere but still

A. has lost;do not find

B. is missing;do not find

C. has lost;have not found

D. is missing;have not found

答案：

A. has lost;do not find

B. is missing;do not find

C. has lost;have not found

(答案→)D. is missing;have not found

解析：lose是个及物动词，如果要表示某物丢失了，只能用被动语态。A项与C项使用的都是其主动形式。missing是形容词，其词义是：lost；not to be found（丢失了），据此，第一空缺处应填人is missing。根据语境，第二个空缺处应填使用现在完成时的否定形式，因为它可以表示目前还未发生的动作。
