Had they known what was coming next, they ___________ second thoughts.
A．may haveB．could haveC．must have hadD．might have had
D
本題考查虛擬語氣的用法。本句是一個倒裝句，可還原為：if they had known what was coming next, they might have had second thought。根據(jù)had known提示，可知是與過去事實相反，因此虛擬語氣主句中應(yīng)該用would/might have done，由此可見答案D符合語境。
