四级长篇阅读

　　大学英语四级长篇阅读的答题小技巧

　　1.整体把握文章的脉络至关重要。

　　段落信息匹配题的题目的顺序与文章的行文顺序完全不符，这就要求考生在阅读文章时整体把握文章的结构和脉络，熟悉文章的写作思路，基本能做到理解每题的中心思想后，能大体定位到文章的`相应部分，而不是漫无目的地在全文的每个段落里搜寻。如样题中的文章：首先引出话题;中间部分主要谈论两方面的内容—大学在全球网罗人才和开展工作，同时大学也在重塑研究方法;最后是大学全球化的影响和作用。把文章这样分成四个部分以后，根据每个题目的内容，就可以找到大体的位置。

　　2.准确理解题目的内容是前提。

　　每一道题都是原文信息的再现或转述，只有理解了题目所述内容，才能做好后面的段落信息定位。理解题目内容的关键是：抓句子的主干。冗长的句子，只要抓住了其主干，就不难理解句子的主要含义了。

　　3.找准题目中的定位关键词是关键。

　　每一道题都是原文信息的再现或转述，只要找准关键词才能准确定位到原文的段落中。关键词多为：a. 名词或名词短语，这类词是题目和文章谈论的对象，同义替换的可能性较小，是比较可靠的定位关键词，如样题中第46题中的American universities, global careers, internship 都可以在原文中直接找到;b.数字，如数量、年份等，这类词同义替换的可能性非常小，是较理想的定位关键词，如样题中第47题中的3.9 percent, 是原文信息的再现;c. 专有名词，如人名、地名、机构名、特殊物质等，这类词几乎没有同义替换或转述的可能性，是非常理想的定位关键词，如样题中第55题中的Danah Boyd就是一个专有名词，可以在原文中直接找到。

　　大学英语四级长篇阅读的解题步骤

　　1、扫描题干，划出关键词。选项不要看，用时越短越好。

　　2、通读全文，抓住中心。

　　3、仔细审题，返回原文。关键：定位。

　　定位的三大原则：

　　(1)关键词定位原则：由题干出发，寻找题干中的关键词，首选大写字母、数字等，其次是表时间地点人物的词。

　　(2)自然段定位原则：出题顺序与文章段落顺序大体一致。

　　(3)出题点定位原则：答案一定蕴涵在有特殊标点符号、句式列举、强转折逻辑关系的地方。

　　4、重叠选项，斟酌答案。

　　(1)缩小范围的是答案。

　　(2)扩大范围的不是答案。

　　(3)原文和选项有交叉内容的不是答案。

　　(4)不相关的不能选。即，只要选项中有文章中未出现内容就错。注意，将文章中的每一个选项带回文章一一查对，不要凭印象猜测。

　　Passage Two

　　Questions 61 to 65 are based on the following passage.

　　Some of the world’s most significant problems never hit headlines. One example comes from agriculture. Food riots and hunger make news. But the trend lying behind these matters is rarely talked about. This is the decline in the growth in yields of some of the world’s major crops. A new study by the University of Minnesota and McGill University in Montreal looks at where, and how far, this decline is occurring.

　　The authors take a vast number of data points for the four most important crops: rice, wheat, corn and soyabeans(大豆). They find that on between 24% and 39% of all harvested areas, the improvement in yields that took place before the 1980s slowed down in the 1990s and 2000s.

　　There are two worrying features of the slowdown. One is that it has been particularly sharp in the world’s most populous(人口多的)countries, India and China. Their ability to feed themselves has been an important source of relative stability both within the countries and on world food markets. That self-sufficiency cannot be taken for granted if yields continue to slow down or reverse.

　　Second, yield growth has been lower in wheat and rice than in corn and soybeans. This is problematic because wheat and rice are more important as foods, accounting for around half of all calories consumed. Corn and soyabeans are more important as feed grains. The authors note that “we have preferentially focused our crop improvement efforts on feeding animals and cars rather than on crops that feed people and are the basis of food security in much of the world.”

　　The report qualifies the more optimistic findings of another new paper which suggests that the world will not have to dig up a lot more land for farming in order to feed 9 billion people in 2050, as the Food and Agriculture Organisation has argued.

　　Instead, it says, thanks to slowing population growth, land currently ploughed up for crops might be able to revert(回返)to forest or wilderness.This could happen. The trouble is that the forecast assumes continued improvements in yields, which may not actually happen.
