错综虚拟语气考试试题

请问各位老师这道题是选D还是A呢？虚拟语气的错综虚拟不太了解呢，麻烦老师们解说一下呢?

Had Judy been more careful on the maths exam, she ______ much better results now.

A.would be getting

B.could have got

C.must get

D.would get

Had Judy been more careful on the maths exam, she ______ much better results now.

A.would be getting

B.could have got

C.must get

D.would get

虽然主句中用了时间状语now, 但谓语动词get better results意味着她已经得到不理想的成绩了。假设她考试更小心一些是与过去事实相反的假设。在此基础上的推断她得到的结果会比实质得到的结果好的多（也是与过去事实相反的推断）。所以主句的now是出题人的错误，或者勉强将now理解为表示then的意思。逻辑决定了主句谓语get的时间是过去，而不是目前或以后。所以本句正确答案为B：could have got (本可能获得更好的成绩）。
