37、ays of Spending Summer VacationFrom the table we can see that in the past ten years the number of students who go traveling and do social investigation during summer vacation has increased greatly while that of those who stay at home has decreased a lot. The possible reasons for this are as follows.

38、To begin with, with the development of economy many people have be come rich. More and more students are able to get financial support from their parents for traveling. Also, tourism has greatly developed over the past ten years. Many new scenic spots have been constructed. Secondly, the open-door p

40、e students will make their summer vacation interesting and meaningful by going to the outside world instead of staying at home.)解析：简评这是一篇给出英文提纲的图表式说明文。根据提纲要求，文章首段点明十年间大学生过暑假方式的变化：去旅行和做社会调查的人数大大增加，而待在家里的人数大大减少。第二段作者分析了这种变化的原因，认为最大的可能是许多家庭的收入增长了，父母能支付孩子去旅行；其二是经济开放政策给政治和经济方面带来了很大的变化，政府鼓励大学生去做社会调查了解城市和农

41、村的发展。在第三段作者预测越来越多的大学生会在暑假走出家门，使暑假更有乐趣和意义。文章条理清晰，层次分明，是一篇规范的图表式因果法作文。二、Part Reading Compr(总题数：0，分数：0.00)三、Origins of a Plague(总题数：10，分数：70.00)2.The writer of the article feels that the theories of an AIDS transfer from monkey to man are just as crazy as many other theories.（分数：7.00）填空项 1:_ （正确答案：N）解析

42、：文章第二段的中间有这样一句话“. but it does reveal one major point of consensus: African monkeys are almost certainly the source of the deadly virus.”，也就是说“艾滋病是由猴子传染给人的”已是一个公认的事实，而且作者也相信这一点。所以这句话是错误的。3.The AIDS virus is very delicate and can be killed by being ex posed to air or stomach acid.（分数：7.00）填空项 1:_ （正确答

43、案：Y）解析：本句符合原文第八段第二句话。4.The U.S. Food and Drug Administration has acted against similar contamination incidents like that involving SV40 out of fear of a wider spread of AIDS.（分数：7.00）填空项 1:_ （正确答案：N）解析：本句可对应原文第五段最后一句话。虽然这句话告诉我们，美国的食品与药品协会是从 1961 年发现 SV40 病毒后才对实验室中疫苗的培养条件有了严格的要求。但这个决定的起源来自于“Sabin 和Ko

44、prowski 在培养小儿麻痹症疫苗时无意中导致疫苗被污染”这个事实。同时，SV40 也是他们这个事件的副产品。所以这句话是错误的。5.The AIDS epidemic is worse in American cities than in African cities.（分数：7.00）填空项 1:_ （正确答案：NG）解析：文章没有对这两个国家的城市中的艾滋病感染状况进行比较。6.Some experts believe that, if not for the cultural changes that Africa has experienced, the AIDS virus wo

45、uld not have spread to its present extent.（分数：7.00）填空项 1:_ （正确答案：Y）解析：本句符合文章第十二段第一句话，同时，这一段的第三句话用虚拟语气的句式说明了“如果不是文化方面的原因，艾滋病可能已经消失了”。7.Some rural African were infected with AIDS because they were given injections of Koprowskis vaccine.（分数：7.00）填空项 1:_ （正确答案：N）解析：从原文第八段中可知，这两个人的疫苗都不是通过注射来接种的，所以这句话不对。8.Among the theories to explain the origin of AIDS, the polio vaccine theory, in the opinion of the author of the article, seems
