21、最后一段倒数第二句“It also showed that a worldwide change to organics could actually increase the worlds food production by as much as 50% enough to feed a population of 9 billion people with the land we have now.”可知，研究表明，全球范围内改变为有机农业的做法实际上可以使世界粮食产量增加多达50%，即利用我们现在拥有的土地就足以供养90亿的人口。由此可知，通过发展小型有机农业可以养活世界上不断增长的人
22、口。故选C。2答案与解析：A推理判断题。根据第二段的“In study after study, the message aboutagriculture is: To feed the world, we need to support sustainable agriculture on different, local, family farms that work with nature.”和第三段的“In 2008, an international study found that sustainable agriculture, not GM crops, shows more
23、hope of ending hunger.”可知，为了养活人们，各国需要支持本地家庭农场发展可持续农业。2008年，一项国际研究发现，可持续发展农业而非转基因作物显示出消除饥饿的更大希望。由此判断出，如果世界各国支持可持续农业的发展，就不会有食物问题。故选A。3答案与解析：D推理判断题。根据文章倒数第二段最后一句“The report warns that expensive, shortterm ways including GM crops are not likely to cut down longterm hunger, and could even make environmen

25、故选B。.七选五【语篇解读】本文是一篇说明文。介绍了有史以来最大的百科全书维基百科。1答案与解析：F根据上文Encyclopedias used to be printed as books.可知百科全书以前是以书籍的形式印刷的。由此可知，本句是在说明百科全书目前的情况，前后时间上形成对比。此外F 中的代词they指代前一句中的Encyclopedias。故F选项“现在，他们大多在网上找到”符合上下文语境，故选 F。2答案与解析：D根据上文“Wiki” is an internet term that means “a website that can be edited by the pub
26、lic.” It comes from “wikiwiki”，a Hawaiian word for “quick”. Two Americans, Jimmy Wales and Larry Sanger, created Wikipedia in 2001. 可知“维基”是一个互联网术语，意思是“可以由公众编辑的网站”。它来自于夏威夷语“wikiwiki”，意思是“快”。两名美国人，Jimmy Wales和Larry Sanger 在2001年创建了维基百科。以及后文It has about 6 million articles in 300 languages and is visite
27、d by billions of people each day, who want to find information on just about anythingscience, math, languages, art, culture and company histories. 可知它有300种语言的600万篇文章，每天有数十亿人访问它，他们想要找到关于任何东西的信息科学、数学、语言、艺术、文化和公司历史。由此可知，上文介绍了维基百科名字的由来、创始人、以及所收藏的信息，本句承接上文继续围绕维基百科介绍。且后面句子里的主语It，与D 选项中的It指代一致。故D 选项“它现在是互联
28、网上访问量第五大的网站”符合上下文语境，故选D。3答案与解析：B本句为段首语，根据下文Except for a small number of pages, anyone can edit articles, anonymously or with a user account, and registered users can create their own articles.可知除了少数网页外，任何人都可以以匿名的形式或使用用户名对文章进行自由编辑。由此可知，本段介绍的是维基百科的编辑模式。故 B选项“维基百科采用开放编辑模型”符合上下文语境，故选B。4答案与解析：G本句的位置在段首，引
29、出一个新的话题。结合后文Many Wikipedia pages contain errors, although the organization has a content review system that works to fix this problem.可知许多维基百科页面包含错误，尽管该组织有一个内容审查系统来修复这个问题。由此可知，本段介绍的维基百科所存在的问题， G选项中However是一个重要的衔接标志词，表明后面的内容与前面的信息相反。故G选项“然而，有些人怀疑维基百科内容的准确性”符合上下文语境，故选 G。5答案与解析：A该题位于段落之中。根据下文It does not rely on advertising.Instead, all of its funds come from donations.可知它不以广告盈利。由此可知，本句是在说明维基百科的资金来源，句中Instead作为一个重要的衔接标志词，使得该句与前句形成对比。故A选项“如今，维基百科面临着许多挑战。”符合上下文语境，故选A。
