Question

Since the end of the war, many of the priceless antiques ______ to their rightful owners．

1. A.
   have returned
2. B.
   had returned
3. C.
   had been returned
4. D.
   have been returned

Answer 1

Ｄ
试题分析：从时间状语Since the end of the war可以得知用现在完成时，而且antique与 return为被动关系，故用现在完成时的被动语态。句意：自从战争结束以来，许多无价的古董已归还失主。
考点：考查时态和语态
点评：时态题的考查要注意关键词，本题的关键词是时间状语Since the end of the war！经常与现在完成时连用。ＢC都是与过去有关的时态，故排除。
