利用排除法解题根据上下文语境确定答案 根据上下文语境确定答案 近年来的完形填空试题在选项的设置上越来越淡化语法结构，重在文意的干扰，即把具体的语言知识溶进具体的语言情景中去，考查考生通过上下文的前后提示或暗示，对整体文意进行把握的能力。这种考查方式所占的比例较大，且难度也大，若单纯从句子或个别段落来分析，或许所给的四个答案在语法和结构上都是正确的，若放在全局，则不一定正确。因此，快速浏览全文，领悟文章主旨，通过上下文的语境来选择答案是解决这类题的关键。 例如， It was a cold January in 1925 in Nome, Alaska. The town was cut off from the rest of the world due to heavy snow. On the 20th of that month, Dr. Welch   36   a sick boy, Billy, and knew he had diphtheria, a deadly infectious(传染的) disease mainly affecting children. The children of Nome would be   37   if it struck the town. Dr. Welch needed medicine as soon as possible to stop other kids from getting sick.   38  , the closest supply was over 1,000 miles away, in Anchorage. 36. A. examined B. warned C. interviewed D. cured 37. A. harmless    B. helpless  C. fearless    D. careless 38. A. Moreover    B. Therefore  C. Otherwise    D. However 【解析】 37. B考查形容词辨析。A.harmless无害的；B.helpless无望的；C. fearless不怕的；D.careless粗心的。如果白喉肆虐诺姆，那里的孩子们都将毫无希望，故选B。 新概念英语视频 新概念英语视频教程 新概念英语 38. D考查副词辨析。A.Moreover而且；B.Therefore因此；C.Otherwise否则；D.However然而。然而，最近的药品供应站距离诺姆一千多公里，前后是转折关系，故选D。 本文讲述的是曾发生在一个小镇上人们通过接力运送药物来救助患病儿童的感人故事。1925年1月份的阿拉斯加北部极其寒冷，由于大雪，诺姆小镇与外界隔绝了。雪上加霜的是，那里的孩子患了一种致命的传染病——白喉。为了拯救孩子们，人们接力运送药品到诺姆。最终，人们通过狗拉雪橇把药物送到了诺姆。从以上小题可以看出，只要理解了大意，通过语境解答这几个小题并不是难事儿。 根据常识及文化逻辑推理 完形填空往往以自身的内容提供完整的语篇信息，其间交织渗透着各类相关的文化背景知识和生活常识，考查考生灵活运用该方面知识的能力。解决这类题目，考生不仅要有广博的知识、丰富的生活经历，还要能够驾驭全文，不仅理解文章的表层意义，而且要弄清文章的深层意义。当对语言的把握不很准确时，可充分利用社会文化知识和生活常识来帮助判断。 例如， How could the medicine get to Nome? The town’s   39   was already full of ice, so it couldn’t come by ship. Cars and horses couldn’t travel on the snowy roads. Jet airplanes and big trucks didn’t exist yet. 39. A. airport      B. station  C. harbor  D. border 39. C考查名词辨析。A. airport机场； B. station车站；C. harbor 港口；D. border边境。根据“so it couldn’t come by ship”可知，这里指港口结冰，故选C。 由于文章后面提到了由于结冰，就不可能通过船过来。船舶停泊在港口是生活常识问题，根据语境和常识很明显就是说的港口。 利用排除法解题 有时我们会遇上这样的情况：对某个题目的正确选项的含义、用法不甚明了、但发现其它选项却有显而易见的谬误，这时候我们可以试试排除法：将干扰项逐项检查验证，凡发现有错误的选项，立即剔除出选择范围。随着选择范围的缩小，选项的准确率就会不断提高。经过这样分析推敲弃误留正，便会水落石出，找出正确答案。排除法如果运用得好，可以收到事半功倍的效果。 I used to believe in the American Dream, which meant a job, a mortgage (按揭)，credit cards, success.

I came upon a shabby house four miles up a winding mountain road   5   the Potomac River in West Virginia. It was   6  , full of broken glass and rubbish. I found the owner, rented it, and   7   a corner to camp in. The locals knew nothing about me,    8    slowly, they started teaching me the   9    of being a neighbor. They dropped off blankets, candles, and tools, and began  10  around to chat. They started to teach me a belief in a   11   American Dream—not the one of individual achievement but of   12  . What I had believed in, all those things I thought were   13  for a civilized life, were nonexistent in this place.   14  on the mountain, my most valuable possessions were my    15   with my neighbors.

There are four of us now in the house, but over time I’ve had nine people come in and move on to other places. We’d all be in   19    if we hadn’t banded together. The American Dream I believe in now is a shared one. It’s not so much about what I can get for myself; it’s about   20   we can all get by  together. 1.
