Question

【题目】________ the driver worn the seat belt, he _________now.

A. Had; would have survived B. Had; would survive

C. Should; would have survived D. Should; survived

Answer 1

【答案】B

【解析】

试题分析：考查虚拟语气。句意：如果那个司机当时系了安全带的话，他现在就能生还了。根据句意可知是对过去的事实进行虚拟，if从句用过去完成时；在if引导的非真实条件句中，如果含有were, had, should，可将if 省略，并将were, had, should放在主语之前，构成倒装句式。与过去事实相反，主句用would/should+have done，但是，主句中含有now一词，说明是对现在进行虚拟，这时，主句用would/could/should+动词原形，故选B。
