C 句意：Mary又没通过驾照考试。如果她练习得再刻苦些的话，她会很容易地通过考试的。本句是if条件状语从句的虚拟语气，是对过去的虚拟，从句应用had +过去分词，主句用would/could/might/should+ have done。故选C。2. D 考查虚拟语气。虚拟条件句中如果if被省略，从句需部分倒装，即把had， should或were放在主语前面。且由句意可知，if条件句表示对现在的虚拟。故D项正确。3. C 考查虚拟语气。结合语境中：would have happened可知表示对过去的虚拟，从句应该使用：if+主语+had+过去分词或者had+主语+过去分词结构。4. D 考查虚拟语气。句意：如果我们误了火车的话，我们就不得不在车站等一个小时。由句意和主句的谓语would have to wait可知，本句是对将来的虚拟语气，故从句应用should/were to+动词原形或一般过去时。5. C 考查虚拟语气的省略。句意：她上星期天没来参加晚会。如果她来的话，她一定会使晚会更加激动人心。根据句意可知，本句是对过去的虚拟，从句应用过去完成时，此时可将if省略，而把had提到主语之前。6. B 考查虚拟语气。句意：如果水门事件没有发生，尼克松就不会辞去总统一职。根据句意和主句谓语would not have resigned from可知，本句是对过去的虚拟，条件句中要用过去完成时。 7. B 考查虚拟语气。句意：如果天下雨，庄稼就会得救。本句为虚拟语气的省略句，且是对将来的假设，应用should。8. A 考查虚拟语气。句意：如果Rose将钻石放在一个更安全的地方，那么钻石就可能不会被偷了。由句意可知if虚拟条件句表示与过去事实相反。故A项正确。 9. D 考查虚拟语气。前句句意：谢谢你昨天提醒我时间，不然昨天我就迟到了。从语境可知说话人是在谈论昨天的事，因此要使用情态动词would + have done。故D项正确。10. B 考查虚拟语气。句意：他昨天很忙，否则他就会帮你做实验了。根据句意可知前句用陈述语气，根据时间状语yesterday可知应使用一般过去时。后句表示与过去情况相反的假设，使用虚拟语气，谓语为would have done。11. B 考查虚拟语气。从句子中if my mother hadnt reminded me可知，此处是对过去事实的虚拟，主句应该用should/would/could/might + not + have + done结构，只有B项正确。12. C 考查虚拟语气。句意：如果一开始就考虑到运费，这个公司就会建在远离现在地点的位置。根据主句谓语可知句子使用虚拟语气，表示与过去的事实相反，从句谓语用过去完成时。13. C 考查虚拟语气的省略。句意：如果我去北京的话，我就能参观皇帝曾经居住过的紫禁城了。根据句意可知，本句是对将来的虚拟假设，从句应用should/were to +动词原形，此时可以将should或were提到主语之前，且if省略。14. D 考查虚拟语气。句意：如果下周在我们的城市有艺术展的话，我们班就可以去欣赏了。根据句意可知，本句是对将来的虚拟假设，故从句用should +动词原形，主句用would + 动词原形。15. C 考查虚拟语气。句意：真遗憾那位老人死了。如果他女儿了解更多急救知识的话，她就会挽救他的生命了。根据句意可知，本句是对过去的虚拟，主句应用woul
