My dictionary__________. I have looked for it everywhere but still
A．has lost;do not findB．is missing;do not find
C．has lost;have not foundD．is missing;have not found
D
 lose是個及物動詞，如果要表示某物丟失了，只能用被動語態(tài)。A項與C項 使用的都是其主動形式。missing是形容詞，其詞義是：lost；not to be found（丟失了）， 據(jù)此，第一空缺處應(yīng)填人is missing。根據(jù)語境，第二個空缺處應(yīng)填使用現(xiàn)在完成時的否定形式，因為它可以表示目前還未發(fā)生的動作。
