Question

【題目】_______ the morning train, he would not have been late for the meeting.

A. Did he catch B. should be catch

C. has he caught D. Had he caught

Answer 1

【答案】D

【解析】本題實(shí)際上是一個(gè)條件狀語(yǔ)從句的虛擬語(yǔ)氣，表示與過(guò)去事實(shí)相反。條件句中使用“過(guò)去完成式”，主句使用“情態(tài)動(dòng)詞+have done”；當(dāng)條件句中的if省略的時(shí)候，要把had提前形成部分倒裝。句義：如果他趕上了早班火車(chē)，他就不會(huì)開(kāi)會(huì)遲到了。故D正確。
