(答案→)B. did he
C. has he
D. could he
解析：考查反义疑问句。本题前半句是一个否定前移的形式，本应该是I suppose Jim could not have done so well in yesterday’s exam.在英语中I suppose是一个插入语，可以省略。本句就变成了Jim could not have done so well in yesterday’s exam.本句中的“情态动词+have done”表示推测，如果句子有过去时的时间状语，就对过去时反问。如果句中没有过去时的时间状语，就对现在完成时反问。本题句中有in yesterday’s exam,故对过去时反问，故B正确。
