Question

_____________ cease（终止） advertising, prices would be significantly reduced.

A. Were they to   B. Could they

C. If they        D. Would they

Answer

A

【解析】

试题分析：考查虚拟语气和省略倒装句。句意：如果他们停止这个广告，那么价格会显著下降。根据句意可知本句表示与将来事实相反，条件句中有三种结构：were to do，过去时，should+动词原形；同时当if省略，要构成部分倒装的形式，所以A项省略了if，把were提前构成部分倒装。故A正确。

【名师点睛】

本题和11题考点类似，只不过是省略了if，使用了部分倒装的形式。高考例题为：

(2012浙江卷)Had they known what was coming next, they_____second thoughts.

A. may have B. could have

C. must have had D. might have had

答案:D

解析:本句是一个倒装句，可还原为：if they had known what was coming next, they might have had second thought。根据had known提示，可知是与过去事实相反，因此虚拟语气主句中应该用would/might +have done，由此可见答案D符合语境。
