1. If she had worked harder, she______.
A. would succeed B. had succeeded
C. should succeed D. would have succeeded
答：D。与过去事实相反的虚拟语气：从句用过去完成式(had done)，主句用would (should，might，could)+现在完成式(have done)的形式。
2. I wish I_________ you yesterday.
A. seen B. did see
C. had seen D. were to see
答：C。wish后接虚拟语气的从句，若表示与现在事实相反的愿望，谓语用过去式，若表示与过去事实相反的愿望，谓语用过去完成式，若表示与将来事实相反的愿望，谓语用would+动词原形．如：I wish I were ten years younger now 我希望我现在年轻十岁。I wish I would be a scientist. 我希望我将成为一名科学家。
