Question

   has been disappeared; can
2. B.
   has disappeared; could
3. C.
   is missing; should
4. D.
   has been lost; may

Answer 1

B
試題分析：句意：我的新鋼筆不見(jiàn)了。誰(shuí)把它給拿走了？disappear不能用于被動(dòng)，故排除A；sth be missing某物丟了；sth be lost某物丟了；should have done應(yīng)該做而未做；could have done可以用于疑問(wèn)句，表示過(guò)去可能發(fā)生過(guò)某事；may have done表示過(guò)去某事可能已經(jīng)做了，不能用在疑問(wèn)句中；故選B。
考點(diǎn)：考查情態(tài)動(dòng)詞的用法。
