问题补充：

A. Were you to follow
B. Had you followed, wouldn’t be
C. Had you followed, wouldn’t have been
D. If you followed, wouldn’t have been
答案：
A. Were you to follow
(答案→)B. Had you followed, wouldn’t be
C. Had you followed, wouldn’t have been
D. If you followed, wouldn’t have been
解析：考查错综条件句的虚拟语气与倒装。本句条件句是一个与过去事实相反的虚拟语气，中使用过去完成时，如果条件句中省略了if，要使用部分倒装的形式。同时这句的主句中与现在事实相反，要使用“情态动词+动词原形”。句意：如果我昨天采纳了老师的建议，你现在就不会住院。故B正确。
