四、实例讲解
Many teachers believe that the responsibilities for learning lie with the student. _ 71 _ a long reading assignment is given, instructors expect students to be familiar with the _ 72 _ in the reading even if they do not discuss it in class or take an examination. The _ 73 _ student is considered to be _ 74 _ who is motivated (激发); to learn for the sake of _ 75 _, not the one interested only in getting high grades. Sometimes homework is returned _ 76 _ brief written comments but without a grade. Even if a grade is not given, the students is _ 77 _ for learning the material assigned.
When research is _ 78 _, the professor expects the student to take it actively and to complete it with _ 79 _ guidance. It is the _ 80 _ responsibility to find books, magazines, and articles in the library. Professors do not have the time to explain _ 81 _ a university library works; they expect students, _ 82 _ graduate students, to be able to exhaust the reference _ 83 _ in the library. Professors will help students who need it, but _ 84 _ that their students not be _ 85 _ dependent on them. In the United States, professors have many other duties _ 86 _ teaching, such as administrative or research work. _ 87 _ the time that a professor can spend with a student outside of class is _ 88 _. If a student has problems with classroom work, the student; should either _ 89 _ a professor during office hours _ 90 _ make an appointment.

本文是单段文章，首句即揭示了文章的核心思想——许多老师认为学习的责任在于学生。只要抓住了这一点，这篇文章的问题立即次第解开。
71题首选after或when，当然没有选if亦可。
72题首选content，没有选information当然可以。不可选context，那是理解的依据，而非目的。
73从句中motivated推知自然是good，当然ideal更好。
74是代指单数名词的代词，应是one；句中后半立即验证。
75题一想就知不是grades(或marks、scores之类，美国大学多不给具体分数，而是打出等级，最高是A+)，看选项立即想出原来是learning，是为了学习。
76从与后半句对比立即得出with。
77对照文章首句立即可得答案，看选项对比排除亦可。
78看上句最后一词便知。
79看后有说no的冲动，立即感觉有点绝对，改为little，一看选项立即选取中minimum。
82表递进，自然是especially，一看选项，选同义词particularly。
83注意source与origin(有的辅导书解释欠妥)，source类比于fountain，origin是指遥远时空的起源，如The origin of this custom is unknown. 我们注意到selections和collections面都太窄了。
84选个与suggest属一类的后面引起宾语从句其中用虚拟语气的情形，看选项非prefer莫属。
85选too，表嫌其过分，语气正好恰合。86教授自然要教学，当选besides。
87表因果，首选consequently，没有次选therefore亦可。
88除教学外，还要管行政、搞研究，时间自然是有限的(limited)。
89首选consult，次选contact，看选项没有选approach也非常好，居然有annoy晕倒。
90题中or与前面的either连用。
此篇一气呵成，上下文联系极强。此中解题方面颇多，不一而足。多处选项在设计时为调整难度本来就有不少近义词的置换，在此问题上大家对词汇的敏感度要下点功夫喔，这与阅读中的置换原则有关系啊。
