24. C'句意：在经历了一次严重地震化为废墟之后不久，那座城市呈现出了新面貌。本题考查非谓语动词。设空处与suffering from...并列，作介词after的宾语，所以要用doing的形式，排除B;根据短语reduce sb./sth. to sth.使某人/某事物陷入更坏的境地，主语the city和reduce之间是被动关系，所以要用being done的形式，故选C项。
25. B'句意：让那些需要(帮助)的人明白我们会尽全力去帮他们。本题考查非谓语动词作补语。根据let sb.do结构可知B为正确答案。
情态动词和虚拟语气
1. B'句意：既然没人给予他任何帮助，他一定是独自完成这项研究的。本题考查情态动词。must have done表示对过去情况的肯定推测，意为“一定做了”，符合语境。can表推测通常用于疑问句和否定句;would have done表示与过去事实相反的假设，通常用于虚拟语气中;need和have done连用时常用否定形式needn't have done“本没有必要做某事(而做了)”。
2. A'句意：——你不需要带伞，不会下雨的。——哦，我不知道，或许会下。本题考查情态动词。根据语境可知，说话人对是否下雨并不是很确定，因此选择A项might或许。need需要，would将会，should应该，均不符合句意。此题一些考生可能会忽略了答语中的I don't know，而选择了would，误认为说话人要表达的意思是将要下雨。
3. A'句意：没有人可能比他更慷慨，他有一颗金子般的心。本题考查情态动词。A：可能;B：必须，肯定;C：敢;D：需要，有必要。故选A项。
4. D'句意：——本周六你打算做什么?——说不准，不过或许我会去滚石演唱会。本题考查情态动词的用法。根据答语中“I'm not sure”可知是对将来不肯定的推测，故选D项。must必须，一定，语气太强;would表过去将来或表意愿;should应该。
5. D'句意：我过得非常开心(我不可能过得更愉快了)——这真是完美的一天。本题考查情态动词表示推测的用法。couldn't have done... more可以表示“过去不可能更……”的意思，符合此句句意。
6. D'句意：Harry感觉很不舒服，他在昨晚的聚会上一定是喝多了。考查情态动词。根据时间状语last night，得知本句应该属于对过去发生事情的推测，故排除A、B两项。must have done表示“过去一定做过某事”，would have done表示对过去情况的虚拟，常用于非真实条件句中，不符合题意。
7. A'句意：——你的眼睛为什么那么红啊?昨晚你不可能睡得很好。——是的，我熬到很晚写一篇报告。本题考查情态动词用法。can't have done过去不可能做……。
8. B'句意：不可能是词汇导致了你习题中的问题，因为你知道很多单词。本题考查情态动词。根据句意可以得出此处表示否定的推测，排除A和C项。D项不表示推测。故选B项。
9.B'句意：在我小时候，每当我想看电视时就能看。本题考查情态动词。could在此表达过去能够做某事，符合句意。
10. A'句意：孩子们肯定在树林里迷路了，否则他们就会按照计划回到湖边营地了。考查情态动词表推测。根据would have been可知语境指的是过去，排除B和D项;A：肯定已……，C：应该做(而未做)。A项符合语境。
11. D'句意：如果我们早些订位子，现在也就不用站在这里排队了。本题考查虚拟语气。分析语境可知if引导的从句是与过去事实相反的假设，因此选择D项。
12. B'句意：如果他以前花更多的时间练习说英语，他现在就能说得更好些。本题考查虚拟语气。本句为错综时间条件句，即if从句与过去事实相反，主句与现在事实相反。与现在事实相反的主句谓语部分为“would/should/could/might+动词原形”。故选B项。
13. A'句意：——今天早上雨下得很大。很高兴我们带了雨伞。——是的，要是我们没带伞的话我们就被淋成落汤鸡了。本题考查虚拟语气。根据语境提示可判断此处表示与过去事实相反，所以if条件从句中使用过去完成时。
14. B'句意：眼科医生建议孩子的第一次眼睛检查应该在六个月的时候(进行)。本题考查虚拟语气。动词recommend(建议)后加宾语从句，宾语从句的谓语形式为：should+动词原形，should可以省略。
15. C'句意：——你认为乔治通过驾照考试了吗?——没有。要是考过了，他昨天就开车到我们大学来了。本题考查虚拟语气。分析题干可知，if后是非真实条件句，表示与过去事实相反的假设，主句的谓语动词结构为“should/would/could/might+ have+动词的过去分词”，故答案为C项。
16. D'句意：我昨天晚上本来想要去我表兄的生日聚会，但是没有空。本题考查虚拟语气。句中的时间状语last night明确表示应该是对过去事实的虚拟，对过去事实虚拟的形式可以是would have done结构。故选D项。
17. C'句意：如果我(当时)认为你是认真的，我就不会笑了。本题考查虚拟语气。根据should not have laughed可以判定是对过去的虚拟，条件从句中对过去的虚拟要用had done形式，故选C项。
18. A'句意：我妈妈建议我们应该换换口味，这个周末出去吃饭。本题考查虚拟语气。题干中的suggests是解题的标志词，它后面的宾语从句需用虚拟语气，动词使用(should) do的形式，故选A项。
定语从句和名词性从句
1. C'句意：正如古训所说“人不可貌相，海水不可斗量”。本题考查定语从句，先行词为前面一句话。先行词在定语从句中作宾语，故选C项。go在此处意为“说”，相当于say，用作及物动词。
