答案与题解：
1. D 综合第一句的大意，只有 D 选项信息填在这里恰当，A 选项的意思是提议，暗示 ，B语境，上下文 ，C摘要。
2. B 此句大意为理想的学生是为了学习而学习，只有 ideal最符合要求，故选 B。
3. C 本文讲的是与学生学习相关的内容，A，B，D 均不合文意及句意，故排除。
4. D 此处要区分几个介词的含义，be returned with 一般有带着回来之意，此句意为 有时，被发回来的作业上只有简短的评价，并无分数。be returned by 意为被带回来，而 for ，in 于此搭配不当，答案选 D。
5. C be responsible for 是固定搭配，表示对负责任。其他选项放在此处都不合上下文含意。
6. C 此句意思是当一项研究课题被选定时，教授们期望学生积极去做。A 和 D 不合题意，
最大的干扰项 B 意思为分配，分布，一般指一个整体被分散给许多个体，与之相比，C 选项更为合适。
7. B 老师肯定希望学生能够在尽可能少的指导下完成研究。只有 B 选项意为最小的，为正确答案。
8. D 首先排除 B 选项，因为此处需要一个关系副词充当宾语从句的状语，而 what 是关系代
词，之后要看整句的意思，教授们没有时间去给学生解释一个大学图书馆是怎样运作的。A
和 C 虽然符合语法要求，但放此处意思不通，故选 D。
9. A A 选项意为尤其 ，B本质上 ，C明显地，D很少地，难得。此处强调毕业生，A 选项较为合适。
10. C 此句意为教授们期望学生，尤其是研究生阅尽图书馆中的文献资源 。 A 意为选集，B 为集合，两者一般都指文学作品的集合，而此处是学术界的文献。C 与 D 选项都有来源，源头的意思，但 D 选项侧重于起源，开端，C 更侧重于原始资料，为正确答案。
11. D 根据下文意思，A和B 选项可直接排除，教授们肯定是喜欢学生不依赖他们，不是不喜欢。D 选项的含义比 C 选项更递进了一步，符合题意，故选D。
12. A dependent 是形容词，前面不能与 such ，much 搭配，D 选项 more 放在此处构成比较级，但前文并无原级与之相比较，因此只剩下 A 为答案，此句意为教授们愿意帮助那些需要帮助的学生，但更希望学生不要太过依赖他们。
13. D 此题重点在于区分三个有除之外含义的介词。A 选项一般翻译成而不是，并不是 ，B 选项意为除去之外，D 选项意为除去之外还，此句意思为美国的教授除了教书之外还有许多其他的职责，故 D 为答案。
14. B 根据上文含义，一个教授能花在学生身上的时间一定是有限的，A，C，D 不合题意，直接排除，B 选项为正确答案。
15. C 此题还是承接上文含义，正因为教授时间有限，因此学生若想与之沟通，定要等教授在学校的时候，或是提前约好。C 选项意为接近，靠近，为正确答案，其他选项意思与文意不符，A 为问候 ，B 为使厌恶，D 为依附，伴随，添加。
