四、實(shí)例講解
  
  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 (激發(fā)); 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.

　　本文是單段文章，首句即揭示了文章的核心思想——許多老師認(rèn)為學(xué)習(xí)的責(zé)任在于學(xué)生。只要抓住了這一點(diǎn)，這篇文章的問題立即次第解開。 
　　71題首選after或when，當(dāng)然沒有選if亦可。
　　72題首選content，沒有選information當(dāng)然可以。不可選context，那是理解的依據(jù)，而非目的。
　　73從句中motivated推知自然是good，當(dāng)然ideal更好。
　　74是代指單數(shù)名詞的代詞，應(yīng)是one；句中后半立即驗(yàn)證。
　　75題一想就知不是grades(或marks、scores之類，美國大學(xué)多不給具體分?jǐn)?shù)，而是打出等級(jí)，最高是A+)，看選項(xiàng)立即想出原來是learning，是為了學(xué)習(xí)。
　　76從與后半句對(duì)比立即得出with。
　　77對(duì)照文章首句立即可得答案，看選項(xiàng)對(duì)比排除亦可。
　　78看上句最后一詞便知。
　　79看后有說no的沖動(dòng)，立即感覺有點(diǎn)絕對(duì)，改為little，一看選項(xiàng)立即選取中minimum。
　　82表遞進(jìn)，自然是especially，一看選項(xiàng)，選同義詞particularly。
　　83注意source與origin(有的輔導(dǎo)書解釋欠妥)，source類比于fountain，origin是指遙遠(yuǎn)時(shí)空的起源，如The origin of this custom is unknown. 我們注意到selections和collections面都太窄了。
　　84選個(gè)與suggest屬一類的后面引起賓語從句其中用虛擬語氣的情形，看選項(xiàng)非prefer莫屬。
　　85選too，表嫌其過分，語氣正好恰合。86教授自然要教學(xué)，當(dāng)選besides。
　　87表因果，首選consequently，沒有次選therefore亦可。
　　88除教學(xué)外，還要管行政、搞研究，時(shí)間自然是有限的(limited)。
　　89首選consult，次選contact，看選項(xiàng)沒有選approach也非常好，居然有annoy暈倒。
　　90題中or與前面的either連用。 
　　此篇一氣呵成，上下文聯(lián)系極強(qiáng)。此中解題方面頗多，不一而足。多處選項(xiàng)在設(shè)計(jì)時(shí)為調(diào)整難度本來就有不少近義詞的置換，在此問題上大家對(duì)詞匯的敏感度要下點(diǎn)功夫喔，這與閱讀中的置換原則有關(guān)系啊。
