  一、如何排除干扰项
  1. 利用上下文线索排除干扰项
  【例】The professor 37(marched into) the lecture hall, placed upon his desk a large jar filled with dried beans, and invited the students to 38 how many beans the jar contained. After 39(listening to) shouts of wildly wrong guesses the professor smiled a thin, dry smile, announced the 40(correct) answer, and went on saying,“You have just 41(learned) an important lesson about science. That is: Never 42(trust) your own senses.”...
  38. A. count
  B. guess
  C. report
  D. watch
  解析:解此题要结合下文中的“shouts of wildly wrong guesses”。此处指“教授让学生猜罐子里有多少颗豆子”, 故选B。
  2. 利用语篇标志排除干扰项
  【例】I 34(stopped) and dropped all the coins into his 35(hat), and he smiled at me, I watched for a while. As 36(selfish) as it sounds, I expected something more to come from that moment——a feeling of 37(happiness) or satisfaction, for example. But nothing happened 38 , I walked off. “It proved to be a waste of 39(money),”I thought.
  38. A. Disappointedly B. Unfortunately
  C. Coincidentally D. Comfortably
  解析:上文的关键词expected表明作者期待着什么,这里的语篇标志词But说明作者期待的事情没有发生,因此作者是感到失望,故选A。
  3. 利用首句信息排除干扰
  【例】Around the world young people are spending unbelievable sums of money to listen to rock music. Forbes Magazine reports that at least fifty stars have incomes between two million and six million dollars per year.
  A. film B. rock
  C. jazz D. movie
  解析:由首句可知A、C、D为干扰项,故选B。
  4. 同比排除法(即排除意义相同或类别相同的选项)
  【例】“And of course, you’re Mr. Faber.” She said, .
  A. questioning
  B. wondering
  C. smiling
  D. guessing
  解析:由于A、B、D在干扰角度上相近,故都排除,选C。
  5. 摆脱思维定势,逆向思维排除干扰项
  【例】It isn’t really true that he was too 31(lazy) to work——in fact he had tried a few 32 (jobs). First of all he was a window-cleaner and in his first week he managed to 33 at least 6 windows.
  33. A. rub B. drop
  C. break D. clean
  解析:John干窗户清洁工和干其他工作一样,总是出差错,应该选择C才符合语境。可是有些考生受思维定势的影响,不敢选。他们认为manage to do sth.是“成功设法做某事”,因而误选答案D。可是 John一周下来怎么只擦了六扇窗户呢?其实这儿的 managed to do是说John的无能,多少有点调侃的意味,意思是“竟然做了某事”。另外从下文他的遭遇和工作失误,以及 It seemed that there was no suitable work for him.这一句所提供的信息也可以说明答案C是正确的。
  6. 用语法分析排除干扰项
  【例】When Ed first phoned and 37 we play, I laughed quietly...
  37. A. declared B. mentioned
  C. persuaded D. suggested
  解析:后面的句子是虚拟语气,因此用suggested,故选D。
  7. 利用习惯用法和词语辨析知识排除干扰项
  【例】The lecture on smoking was over at last. As we were rushing towards the playground, Jim slipped by the table. The watch, which Mrs.Smith had 1(laid) on the table as she started her lecture, disappeared.

 We were 2 to go back for class again when the headmaster called us 3(together) and said, “I’ve got a little 4(job) for you boys...”
  2. A. about B. able C. sorry D. sure
  解析:这里有一个特殊的句型:be about to do... when...,表示“正要干什么,就在这时(突然间)发生了什么事情”。如果考生对这个句型熟悉,就会毫不犹豫地选A项。其他三个形容词虽然都可以和不定式连用,但放在语境中都不合适。
  8. 利用文化背景和生活常识排除干扰项
  【例】When the papers were 27, she discovered that twelve boys had made exactly the same mistakes throughout the test.
  27. A. examined B. completed
  C. marked D. answered
  解析:根据常识,学生刚刚答完交卷时,老师是无法“发现同学们犯了相同的错误”的,只有在“给(试卷等)打分”时才有可能,故选C。
