25.D

26.D解析：which修饰非限定性定语从句，指代前边一句话。本题涉及句法知识——简单句、并列句和复合句。例如：Hehastwodaughters.Theyaredoctors.(简单句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(复合句)

34.B考查反义疑问句。原句应是：youwouldthinkhehadhaveforgotten…反义疑问句的规则是陈述部分是肯定式，疑问部分应是否定式。Wouldthink表示推测，疑问部分也应选择would。选项B是正确的。【句子大意】你难道还认为他已经忘掉了，是吗?

44.C解析：notonly…butalso连接主语时，谓语动词根据就近原则由butalso后的成分来决定。TomandMary是两个人，所以动词用复数形式。

45.A解析：本题考虚拟语气在名词性从句中的用法。在“ask(advise，desire，ordersuggest，require，etc。)+the广引导的从句中，谓语动词应用“should+认”，should可以省去，再结合语态，故A项正确。本句大意为：他们要求所有的必要文件都必须在月底之前交到校长办公室。

46.A解析：句意：她昏倒了。给她脸上浇些水，或许她会醒过来。本题考查词组辨析。comeround：过访，绕道而来，苏醒过来；comeback：回来，恢复；comeagain：再说一遍，重复一遍；comeout：出来，传出。
