It三、例题精析【例题 1】【 干】 (2014北京卷 )We _back in the hotel now if you didnloset the map.A. areB. wereC. will beD. would be【答案】 D【分析】 本 观察的是if条件状 从句的虚 气。表示与 在事 相反 ，条件句中使用“一般 去 /were”，主句使用 “情 + 原形 ”。句意：假如你没有把地 了，我在就会在 里了。依据从句的did可知本句是与 在事 相反，故D 正确。【例题 2】【题干】 1._ it rain tomorrow, we would have to put off the visit to the Yangpu Bridge.（2012 吉林高考 ）A. WouldB. ShouldC. WereD. Will 【答案】 B意：假如明日下雨，我们就会不得不推延去观光杨浦大桥。依据从句的tomorrow 可知本句是与未来事实相反，故 B 正确。【例题 3】【题干】（ 2014湖南卷） 22.If Mr. Dewey _ present, he would have offered any possibleassistance to the people there.A. were B. had been G. should be D. was【答案】 B【分析】 此题观察的是条件状语从句的虚构语气中的与过去事实相反的状况。反的虚构语气，条件状语从句要使用 “过去达成时 had done”，主句要使用 “神态动词 +havedone ”。句义：假如 Mr Dewey 在场，他就会向那边的人供给保证。依据本句后边主句中的与过去事实相would have offered说明与过去事实相反，故从句中使用过去达成时。故B 正确。【例题 4】【题干】（ 2014天津卷） 15. _ the morning train, he would not have been late forthe meeting.A. Did he catch B. should be catch C. has he caught D. Had he caught【答案】 D【分析】 观察省略和倒装以及虚构语气。 此题其实是一个条件状语从句的虚构语气，表示与过去事实相反。条件句中使用 “过去达成式 ”，主句使用 “神态动词 +have done”；当条件句中的 if省略的时候，要把 had提早形成部分倒装。句义：假如他追上了早班火车，他就不会开会迟到了。故 D正确。四、讲堂运用【基础】【例题 1】【题干】 1.
