四六级考试阅读技能：归纳推理

　　归纳

　　归纳是一种由特殊(个别)到一般的概括，从阅读理解角度说，所谓个别即具体细节，所谓一般即章节段落的大意或主题，归纳是由特殊细节推向一般主题的概括过程。我们可以借助词的上下义关系来领会掌握并运用归纳这一方法。

　　(1) 句子的归纳

　　A) Microwave ovens have eliminated many of the inconveniences previously associated with the preparation of meals.

　　B) Many foods can go directly from the freezer to the microwave oven without being defrosted.

　　C) Many microwave ovens can be pre-set to cook food while you are away from the kitchen.

　　D) The microwave oven has greatly reduced the amount of time it takes to cook a meal.

　　题中四句话都提到微波炉的好处，其中B、C、D 分别从方便、解冻、定时三个不同的方面具体讲述微波炉不同于传统炊具的优势，而A则从整体上覆盖了上述三句的内容，故A是对B、C、D的概括，上述分析、寻找最具概括意义之选项的过程即为归纳过程。推而广之，我们可用之于段落和短文主题的归纳。

　　(2) 段落大意的归纳

　　Although most universities in the United States are run on a semester system, which offers classes in the fall and spring, some schools observe a quarter system comprised of fall, winter, spring, and summer quarters. The academic year, September to June, is divided into three quarters of eleven weeks each beginning in September, January, and March, the summer quarter, June to August is composed of shorter sessions of varying length. Students may take advantage of the opportunity to study year around by enrolling in all four quarters, Most students begin their programs in the fall quarter, but they may enter at the beginning of any of the other quarters.

　　A) Universities in the United States

　　B) The Academic Year

　　C) The Quarter System

　　D) The Semester System

　　本段由四个句子组成，各句大意分别为：1)有些学校实行四学期制；2)学年从9月至下年7月，前三个学期各长11周，夏季学期最短；3)学生可于任何学期注册入学；4)但大多数学生秋季入学。通过上述四句大意的归纳，可知本段落主要讲述美国大学的一种学期制，即Quarter System，答案为C。

　　(3) 短文主题的归纳

　　①Proponents of father-attended childbirth assert that the father‘s experience encourages him to develop a closer bond with his child…

　　②As a father of three teenagers from a previous marriage, one man compared his past experience as a new father to being in the delivery room during the birth of his newborn daughter…

　　③ Women report that they are much less anxious and more aware of what is going on when their husbands are with them when they give birth…

　　A) The Father-Daughter Relationship

　　B) Baby‘s First View of Life

　　C) Dad in the Delivery Room

　　文章共三段，分别给出了各段的主题句。第一段谈赞成女子分娩时丈夫陪在其身边的观点并认为这一经历有利于将来父子关系的发展；第二段从男子的角度谈妻子分娩时陪在其身边的感受；第三段则从女子自身的角度提到分娩时有丈夫在身边会感到踏实、放心。通过对三段主题句的综合概括，全文共同讨论的是：女子分娩时要不要未来的父亲候在产房，因此答案为C。

　　推理

　　阅读除了需要理解文章的字面语义外，更需要透过字里行间领悟言外之意及作者的语气、态度，这就要求读者具有一定的推理能力。推理的前提就是阅读到的有关文字——可能是短语或句子或整个段落甚至整篇短文。读者必须由表及里、由此及彼，从字里行间悟出合乎作者本意的言外之意。推理的结果应是既来自于字里行间、又高于字里行间；既符合原文实际内涵，又超越实际内涵；既基于已知事实，又不仅仅是已知事实。

　　正确的推理要求：

　　1忠于原文，切忌用自己的观点取代作者原意；

　　2注意作者遣词造句的特点和倾向，客观推测作者立场、观点和写作意图；

　　3由同一已知事实可推出不止一个正确的结论。

　　例：Apart from the obvious fact that rioters tend to come from the less well-off section of the community, there is no evidence that economic circumstances have any causal relationship with street violence.

　　A) There is some evidence for relating economic circumstances to street violence.

　　B) Not all the people in the community referred to are poor.

　　C) There is no evidence that economic circumstances result from street viloence.

　　D) All rioters come from the poorer section of the community.

　　本例中，只有A可由原文推知，其中Apart from所引述的正是经济环境与暴力的一种相关性；C否定了这一相关性，故与原文相悖；D与原句中“rioters tend to come from…”的原意不符：“往往”不等于“总是”；B则是原文第一部分的重述，不属推论。
