题型简介：

　　老四级阅读理解中未曾出现过15选10题型。部分备考的四级学员“谈新色变”。本题型出现在仔细阅读部分（共25分钟），在两篇传统阅读文章之前（每篇文章解题时间约为9分钟）。所以本题型共10道小题最佳完成时间应控制在7分钟。

　　阅读理解，真的要我们既要“阅读”又要“理解”吗？其实是不需要的。笔者根据多年的教学经验，为大家解密四级新题型。

　　考点解密：

　　一．核心要求：识辨词性。这是以前考试当中很少涉及的部分。考试要求在7分钟左右时间内将题目给出的15个词汇填入10个空格中。考核的主要目的是检查考生的单词词性识别能力。

　　二．四词用法：名词；动词；形容词；副词。纵观样题和真题，我们知道15个词汇都属于最重要的四类实词。我们要学会每种词汇的基本搭配和基本用法。

　　三．寻求突破：副词突破。考试题目中选项最少，特征也最为明显。

　　四．一一对应：“一个罗卜一个坑”。也就是说，答案是只能使用一次的。所以还要稍微注意前后的语意的通顺和连贯。

　　解题步骤：

　　鉴于以上分析，笔者给出题型步骤如下：
　　一．标注词性，预先分组　把题目中给出的15个备选答案词汇进行词性分组。

　　二．浏览全文，预测答案　快速扫描文章，预测缺省信息的词性，对个别题目作出预测。

　　三．同性比较，选择唯一　对相同词性词汇与原文意思进行比照，选择唯一的答案。利用上下文线索，词的褒贬色彩，平行结构，单复数，时态等解题。

　　四．带入选项，通读检查　带入已选答案，重新通读文章以核对其是否逻辑语意正确。

　　真题精析

EI Nino is the name given to the mysterious and often unpredictable change in the climate of the world. This strange 47   happens every five to eight years. It starts in the pacific Ocean and is thought to be caused by a failure in the trade winds(信风), which affects the ocean currents driven by these winds. As the trade winds lessen in 48, the ocean temperatures rise, causing the Peru current flowing in from the east to warm up by as much as 5℃.

       The warning of the ocean has far-reaching effects. The hot, humid (潮湿的)air over the ocean causes severe49 thunderstorms. The rainfall is increased across South America, 50 floods to Peru. In the West Pacific, there are droughts affecting Australia and Indonesia. So while some parts of the world prepare for heavy rains and floods, other parts face drought, poor crops and  51.

       EI Nino usually lasts for about 18 months. The 1982-83 EI Nino brought the most 52 weather in modern history. Its effect was worldwide and it left more than 2,000 people dead and caused over eight billion pounds 53 of damage. The 1990 EI Nino lasted until June 1995. Scientists 54 this to be the longest EI Nino for 2,000 years.

       Nowadays, weather experts are able to forecast when an EI Nino will 55, but they are still not 56 sure what leads to it or what affects how strong it will be.

[F] phenomenon  
[B] strength   
[E] tropical   
[L] bringing  
[K] starvation   
[J] destructive 
[N]  worth 
[A] estimate
[O] strike  
[I] completely
[C] deliberately
[D] notify

[G] stable 

[H] attraction

[M] exhaustion

47【解析】选[F]。 空格前为一形容词，通常其后修饰名词，可推知空格处要填一单数名词。从前文可知，所填名词指代EI Nino（厄尔尼诺）这种奇怪的气候现象。选项中共有六个名词，而能指代EI Nino的只有[F] phenomenon（现象）。
