【答案解析】[解析] Many computer users around the globe apparently heeded the warnings about a worm with a sexy name and took precautions to protect their data from the destruction of "Kama Sutra". The worm, also known as Blackworm, Nyxem, and Blackmal, is a type of malware, or malicious software that infects PCs using the Windows operating system. [分析] 对特定信息的找寻和判断。 题干要求判断运用Windows操作系统感染PC的病毒一共有几个名字。根据原文可知，全段都在介绍这一病毒，综合起来发现有如下几个：Kama Sutra，Blackworm，Nyxem，和Blackmal，因此，题干的说法是错误的。 [解题关键] 根据题干中关键词name，着重找寻原文中关于姓名的专有名词。

【正确答案】 B

【答案解析】[解析] The United Nations health agency has confirmed a fourth bird flu death in Vietnam, and says an increased number of patients are seeking treatment for flu-like symptoms in the country's capital. Bird flu has been spreading rapidly among chickens in several Asian countries. [分析] 数字信息的理解和判断。 关于禽流感受感染的人，原文说a fourth bird flu death in Vietnam，因此题干中four people have been killed by bird flu的说法不正确；另外原文说有更多的人在越南首都寻找治疗禽流感的方法，这与题干中many more are having it in the capital of Vietnam“有更多的人在越南首都患禽流感”的说法不符。由此可见，题于的说法是错误的。 [解题关键] 了解新闻体的一般特点。对于短消息而言，一般第一句传达重要信息，如本题中第一句传达了关于越南禽流感情况的重要信息，而第二句则是对该疾病的一般性背景介绍。

【正确答案】 B

【答案解析】[解析] In the American electoral system, people don't really vote for presidential candidates. Instead, voters cast their ballots for "electors" who support each candidate. Each state has as many electors as the total number of its representatives in Congress. This equals two senators per state plus the number of its representatives in the House. The candidate who has the most votes in a state wins all of the state's electors. To win the presidential election, a candidate must gain at least 270 of the 538 total electoral votes. [分析] 比较结构的理解和判断。 原文提到Each state has as many electors as the total number of its representatives in Congress． This equals two senators per state plus the number of its representatives in the House即每州选民的人数与其在国会中的代表人数相等，这相当于每州两位参议员加上该州在众议院的代表人数。由此可判断，题干的说法“即每州选民的人数与其在众议院的代表人数相等”是错误的。 [解题关键] 1)理解比较结构的含义；2)正确理解指示代词的指带意义，如文中This即指前一句的内容。

【正确答案】 A

【答案解析】[解析] Society is all too committed to the notion of "progress" as measured through economic growth and population expansion. The concept of working toward a "sustainable future" is not given much thought. Energy policy, for example, concentrates on expanding supply, with relatively little R&D being devoted to improving the efficiency of energy use. Yet without a change in course, human activities are destined to further degrade the global environment. [分析] 语义的理解和判断。 关于人类社会对进步的理解，文中认为Society is all too committed to the notion of“progress”as measured through economic growth and population expansion．The concept of working toward a“sustainable future” is not given much thought即社会对进步的看法过于集中，总以经济发展和人口增长两项指标来衡量，而未将致力于“可持续性未来”的概念考虑在内。由此判断，题干认为人类社会对进步的概念理解是狭隘的，意思与原文相符，因此是正确的。 [解题关键] 把握对某些表示作者观点的短语的理解，能够正确判断话语的真实含义。如此题中如要把握作者对进步的观点，就必须理解too committed to和not given much thought两个短语的真实意义。

【正确答案】 A

【答案解析】[解析] Uruguay has been a proud exception to the privatizing wave that swept through South America in the 1990s. Its state-owned firms are more efficient than many of their counterparts in Argentina and Brazil ever were. In 1992, Uruguayans voted in a referendum against privatizing telecoms. They rightly observe that some of Argentina's sales were botched, creating inefficient private monopolies. And with unemployment at 15%, nobody is enthusiastic about the job cuts privatization would involve. [分析] 因果关系的找寻和判断。 题干要求找寻和判断Uruguay拒绝私有化的原因。根据题中关键词job loss可定位到原文 And with unemployment at 15％，nobody is enthusiastic about the job cuts privatization would involve，由此可推断，该国拒绝私有化的原因是人们对失业恐惧。因此题干的说法与原文相符，是正确的。 [解题关键] 根据题干中关键词reason的提示，侧重找寻和分析文中某部分内容间的因果关系。
