Question

My new pen ______. Who ______ have taken it?

1. A.
   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：我的新鋼筆不見了。誰把它給拿走了？disappear不能用于被動，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可以用于疑問句，表示過去可能發(fā)生過某事；may have done表示過去某事可能已經(jīng)做了，不能用在疑問句中；故選B。
考點：考查情態(tài)動詞的用法。
