【題目】Had they known that there was an explosion in Thailand，they second thoughts about traveling there.

A. may have B. could have

C. will have had D. might have had

【答案】D

【解析】考查情態(tài)動詞。句意為：如果他們知道泰國會發(fā)生爆炸，對于去泰國旅行這件事他們也許會三思而行。由“Had they known”可知本句說的是對過去的虛擬，主句中的謂語動詞應使用“should/would/could/might＋have done”的結構。故選Ｄ。
