3.【答案】B。解析：考查虚拟语气。句意：按要求，在其他学校完成本科学业的申请人要直接给研究院院长发送两份本科成绩单和学位复印件。It is requested that...表示要求……，句子中使用虚拟语气should+动词原形，should可以省略，因此答案选B。
4.【答案】C。解析：考查动词辨析。句意：季票持有者在特定时间内可以不限次数旅行。A. grants授予(权利等)，给予;B. promises承诺;C. entitles使……有资格(使用);给予……权利;D. presents呈现。根据语境答案选C。
5.【答案】D。解析：考查反意疑问句。句意：他们没有通过驾考的消息使他很灰心，不是吗?句子的主干是the news discouraged him，that they failed their driving test是the news的同位语从句，所以句子的主语是news，作“消息”讲时是不可数名词，所以反意疑问句中不能用复数，又因为前面是肯定句，所以反意疑问句用否定句，故选D。
