一道英语单项!—I’m sorry!I would have taken him to hospital if I had known he was seriously ill.—But_____.[ ]A.you didn't B.you hadn't C.he wasn't D.you aren't
A.you didn't

选A 表示事实上你并没带他去医院

选C. should enjoy

strange +that从句，那么从句就要虚拟：should +动词原形，should 可以省略
这种句式表达说话人的惊讶，即 她竟然喜欢吃药，真奇怪！

A
will，would在中学阶段会提到表示一种倾向性。
也就是说如果用you wouldn't，表示无论你知不知道都不会送他去医院。

答案应该选A。
