细节阅读理解的干扰项原则和解题方法

细节阅读理解的干扰项原则和解题方法
1．包含项原则
在答案选项分析中，假如对A选项的理解概括了对其它三项 (或其中某一项)的理解，那么我们就说选项A与其他三项是包含或概括关系，包含项A往往就是正确答案。如在＂花＂与＂玫瑰＂两选项中，正确答案肯定是＂花＂，花包含了玫瑰。
2．正反项原则
所谓正反项，是指两选项陈述的命题完全相矛盾。两个相互矛盾的陈述不能都是假的，其中必有一真。所以，假如四选项中A、B互为正反项，那我们通常先排除C、D项，正确答案一般在A、B项当中。
3．委婉项原则
所谓委婉，这里是指说话不能说死，要留有余地。阅读理解选项中语气平和、委婉的往往是正确答案。这些选项一般含有不十分肯定或试探性语气的表达，如：probably, possibly, may, usually, might, most of, more or less, relatively, be likely to, not necessary, although, yet, in addition，tend to，be liable to等等，而含有绝对语气的表达往往不是正确答案，如：must, always, never, the most, all, every, any, merely, only, completely, none, hardly, already等等。
4．同形项原则
命题者往往先将正确答案设置在一个大命题范围，然后通过语言形式的细微变化来考察考生的理解能力与分析能力。同形项原则告诉我们：词汇与句法结构相似的选项中有正确答案的存在。

5．常识项原则

议论文中，那些符合一般常识，意义深刻富有哲理，符合一般规律，属于普遍现象的往往是正确答案。
6．因果项原则
阅读理解逻辑推理基本都是通过因果链进行的，前因后果，一步步循序渐进。然而，在推理题型的选项中，有的选项会推理不到位（止于前因），或者推理过头（止于后果），这就是所谓的干扰项。因果项原则规定：假如四个选项中有两项互为同一事物推理过程中的因果关系，那么正确答案就是两个因果项中的其中之一。如果因项可产生几个结果，那么答案就是因；如果果项可以对应几个原因，那么答案就是果。

A new collection of photos brings an unsuccessful Antarctic voyage back to life.
Frank Hurley’s pictures would be outstanding—undoubtedly first-rate photo-journalism—if they had been made last week. In fact, they were shot from 1914 through 1916, most of them after a disastrous shipwreck(海滩), by a cameraman who had no reasonable expectation of survival. Many of the images were stored in an ice chest, under freezing water, in the damaged wooden ship.
The ship was the Endurance, a small, tight, Norwegian-built three-master that was intended to take Sir Ernest Sh ackleton and a small crew of seamen and scientists, 27 men in all, to the southernmost shore of Antarctica’s Weddell Sea. From that point Shackleton wanted to force a passage by dog sled(雪橇) across the continent. The journey was intended to achieve more than what Captain Robert Falcon Scott had done. Captain Scott had reached the South Pole early in 1912 but had died with his four companions on the march back.
As writer Caroline Alexander makes clear in her forceful and well-researched story The Endurance, adventuring was even then a thoroughly commercial effort. Scott’s last journey, completed as he lay in a tent dying of cold and hunger, caught the world’s imagination, and a film made in his honor drew crowds. Shackleton, a onetime British merchant-navy officer who had got to within 100 miles of the South Pole in 1908, started a business before his 1914 voyage to make money from movie and still photography. Frank Hurley, a confident and gifted Australian photographer who knew the Antarctic, was hired to make the images, most of which have never before been published.
13. What do we know about the photos taken by Hurley?
A. They were made last week. B. They showed undersea sceneries.
C. They were found by a cameraman. D. They recorded a disastrous adventure.
14. Who reached the South Pole first according to the text?
A. Frank Hurley. B. Ernest Shackleton. C. Robert Falcon Scott. D. Caroline Alexander.
15. What does Alexander think was the purpose of the 1914 voyage?
A. Artistic creation. B. Scientific research. C. Money making. D. Treasure hunting.
【解析】
13. D 细节理解题。根据文章第二段第二句“they were shot from 1914 through 1916, most of them after a disastrous shipwreck....”可知这些照片记录的是1914年左右发生的一次海难事故。故D项正确。
14. C 细节理解题。根据第三段最后一句“Captain Scott had reached the South Pole....”可知第一个到达南极的是Captain Scott。故C项正确。
15. C 细节理解题。根据文章倒数第二句“... started a business before his 1914 voyage to make money from movie and still photography”可知Alexander认为他的这次航行就是为了挣钱。故C项正确。
