第三篇 Germs on BanknotesPeople in different countries use different types of 1 yuan in China, pesos in Mexico, pounds in the United Kingdom, dollars in the United States, Australia and New Zealand. They may use 2 currencies, but these countries, and probably all countries, still have one thing in common1: Germs on the banknotes.Scientists have been studying the germs on money for well over2 100 years. At the turn of the 20th 3 , some researchers began to suspect that germs living on money could spread disease.Most studies of germy money have looked at the germs on the currency 4 one country. In a new study, Frank Vriesekoop3 and other researchers compared the germ populations found on bills of different 5 .Vriesekoop3 is a microbiologist at the University of Ballarat in Australia4. He led the study, which compared the germ populations found on money 6 from 10 nations. The scientists studied 1,280 banknotes in total; all came from places where people buy food, like supermarkets street vendors and cafes, 7 those businesses often rely on cash.Overall, the Australian dollars hosted the fewest live bacteria - no more than 10 per square centimeter. Chinese yuan had the most - about 100 per square centimeter. Most of the germs on money probably would not cause harm.What we call “paper” money usually isnt made from paper. The U. S. dollar, for example, is printed on fabric that is mostly 8 .Different countries may use different 9 to print their money. Some of the currencies studied by Vriesekoop and his 10 such as the American dollar were made from cotton. Others were made from polymers.The three 11 with the lowest numbers of bacteria were all printed on polymers. They included the Australian dollar, the New Zealand dollar and some Mexican pesos. The other currencies were printed on fabric made 12 of cotton. Fewer germs lived on the polymer notes. This connection suggests that 13 have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand how germs live on money-and whether or not we need to be concerned. Vnesekoop is now starting a study that will 14 the amounts of time bacteria can stay alive on different types of bills.Whatever Vriesekoop finds, the fact remains: Paper money harbors germs We should wash our 15 after touching it; after all5, you never know where your money s been.

Frank Vriesekoop : Frank Vriesekoop 博士是巴拉瑞特大学的食品微生物学家，他率领一个全球研究小组对至少10个国家的纸币展开了分析。他的研究结果是：相对于比较落后贫穷的国家，富裕发达国家的纸币所携带的病菌较少。重要的是，世界各地纸币上的病菌数量都没有达到令人担心的程度。研究还发现纸币使用的年限和材质对纸币的污染程度也有影响。4.

A arms B hands Cface D clothes答案与题解:1.B 冒号后面说的是各国使用钱币的名称:“yuan in China ，pesos in Mexico，pounds in the United Kingdom ，dollars in the United States，Aus往alia and New Zealand” ，所以填人的词必 定与这些钱币有关，而且应该是钱币的总括词。因此选 money 最为恰当。coins 是“硬币”，cheques 是“支票” ，loans是“贷款”，它们都不会是答案。2.A 本题的句子说的是:虽然各国使用的纸币各不相同，它们有一个共同点，那就是纸币上 有病菌。四个选项中 different 是答案。3.D 选century 最合理。选 anniversary (周年)，year (年)或decade都不合逻辑。4.C 本段第二句提供了解答本题的线索。Frank Vriesekoop 的研究与以前的科学家的研究不同，他比较了各国钱币上的病菌数量， 在他之前的科学家的研究范围局限于一个国家的纸币。四个选项中只有 within 表达“在(一个国家)里”的意思。5. A 经过第四题选词的思索过程，本题的形容词很自然会在 different 之后用 countries，指不同的国家。6. C 上一句说 Vriesekoop 比较不同国家纸币携带病菌的数量。本题的句子明确指出他对比 的纸币涉及十个国家。四个选项中只有 gathered (收集)与上下文的意思相匹配。7. A填词所在的句子与前面的主句存在因果关系。为什么要从食品店和食品摊收集纸币呢?因为这些地方常要用现金支付。本题答案是 because。8. C fabric 是“织物”，其制作原料不会是 plastic(塑料)或 rubber( 橡胶)。选 paper 也不对， 因为本句是说明纸币的制作原料通常不是纸。制作 fabric 的原料是 cotton( 棉花)，这是合乎常理的。而且该段倒数第二句也提供了答案。所以答案是 cotton。9.D 本段说纸币的材料一般不是纸，通常是用棉花织物或高分子聚合物制作的。所以选择materials( 材料、原料)是正确的。10. B 本题应当选 team。与 family (家庭成员)，advisor (顾问)或 boss (老板)合作研究不是 没有可能，但总有些离谱。与团队合作研究比较合理。11. D 本段第二句提供了线索，它列出三种纸币，即 the Australian dollar ，the New Zealanddollar 和 some Mexican pesos。选 currencies 是最合理的。另外三个选项都不合适; expenses是“支出”，banks 是“银行” ，statements 是“账单”。12. B 本题只有选 mostly，上下文意思才连贯。13. C 前一句说用高分子聚合物制作的钱币含菌数量较少。本题的句子接着分析说，在高分子聚合物上存活较难。谁存活较难？当然是病菌。本题答案是germs0 dirt, water 和oil 是非生物，不存在生存的问题。14.A 四个选项填入句子后，句子成了： “compare/connect/conduct/command the amounts of time bacteria can stay alive on different types of bills”, 很明显；connect （连接）/conduct （实施）/command（控制）amounts of time是无法成立的。只有compare(比较）不同纸币上病菌存活的时间才是Vriesekoop 要研究的新课题。15. B人们通常是用手接触纸币的。所以接触纸币后要洗手。答案是hands。第十篇Chicken Soup for the Soul：Comfort Food Fights LonelinessMashed potatoes, macaroni and cheese, may be bad for your arteries 1 according to a study in Psychological Science, theyre good for your heart and 2 The study focuses on “comfort food” and how it makes people feel For me 3 ,food has always played a big role in my family,” says Jordan Troisi, a graduate student at the University of Buffalo, and lead author on the studyThe study came out of the research program of his coauthor Shira GabrielIt has 4 non-human things that may affect human emotionsSome people reduce loneliness by bonding with their 5 TV show, building virtual relationships with a pop song singer or looking at pictures of loved onesTroisi and Gabriel wondered if comfort food could have the same effect 6 making peoplethink of their nearest and dearest. In one experiment, in order to make 7 feel lonely, the researchers had them write for six minutes about a fight with someone close to themOthers were given an emotionally neutral writing assignment. Then, some people in each 8 wrote about the experience of eating a comfort food and others wrote about eating a new food 9 ,the researchers had participants 10 questions about their levels of loneliness Writing about a fight with a close person made people feel lonelyBut people who were generally 11 in their relationships would feel less lonely by writing about a comfort foodWe have found that comfort foods are consistently associated with those close to ussays TroisiThinking about or consuming these foods later then serves as a reminder of those close othersIn 12 essays on comfort food, many people wrote about the 13 of eating food with family and friends. In another experiment, 14 chicken soup in the lab made people think more about relationships, but only if they considered chicken soup to be a comfort foodThis was a question they had been asked long before the experiment, along with many other questions, so they wouldnt remember it. Throughout everyones daily lives they experience stress, often associated with our 15 with others, Troisi saysComfort food Can be an easy remedy for loneliness词汇：mashed /mt/ adj被捣成糊浆的macaroni/ macaroni/ n通心粉cheese / ti:z / n奶酪artery/ artery / n动脉assignment / sainmnt / n指定作业reminder / reminder/ n起提醒作用的东西remedy /remedy/ n治疗方法，药物virtual/v:tul/ adj虚拟的注释：fort food：爽心食品2. graduate student：研究生3.

A本句前半句说土豆泥、通心粉等对血管有害（ bad) ，后半句说这些食物对心脏有利(good) 。很明显，前半句与后半句意思相反，所以要选转折连接词but加以连接。2. C 根据常识判断，吃土豆泥不会对personality （性格） .movement （移动）或will （意志力）产生有利影响。随后的文章，多处提到吃爽心食品（ favorite food ）有助于排解孤独感。所以选emotions 是正确的。3.D本题的答案是personally0 For me personally （就我个人而言）与下文的意思很连贯。privately （私下地）、usefully （有用地）或awfully （可怕地）与下文的意思搭不上，所以不会是答案。4. B 本题的答案是looked at0。“looked at non-human things” 相当于“studied （研究） nonhuman things”，与上下文的意思很匹配。looked for（寻找）、looked after （照顾）和lookedup（查找）与下文的意思搭配不上。5.A本句的意思是：人们为了排解孤独感，常常把自己和电视剧、流行歌曲歌手等等联系起来。选项中有四个形容词，应该选哪一个形容词去修饰TV shows 呢？应该选褒义的形容词： favorite （喜爱的）或trustful ( 可信任的）。但对电视剧来说谈不上信任的问题。favorite最合理，是本题答案。6. C 上一句说到，人们为了排解孤独感，常常把自己和喜爱的电视剧、流行歌曲歌手等等联系起来。于是Troisi 和Gabriel 想，通过吃爽心食品让他们想起亲近的人，是不是也能产生同样的排解孤独感的效果呢？四个介词中只有by的词义是“通过”。其余三个介词在含义上都不合适。7.B 选professors（教授）、assistants（助手）或scientists（科学家）不合常理，科学家选实验对象时不会选他们。participants ( 参与者）是本题的答案。8.A本题应该选group，指每一组的参与者。用class （班级）, section （部门）或part （部分）在意义上显然都不合适。9. D 本段叙述试验的几个步骤。第一步要一部分受试者描写与亲人的争斗，其他受试者写情感上中性的话题。第二步（文中用then 加以连接）将上述两组受试者中的每一组再一分为二，一些人描写吃爽心食品的经历，另一些人描写吃新食品的经历。接下来应该是第三步了。从四个选项中寻找，只有Finally 最合适，原来第三步就是最后一步了。1O.D 实验的最后一步是受试者被要求书面回答10个问题。complete 是答案。要求他们remember（记住）、delete （删除）或rewrite （重写） questions 都不合乎逻辑。11. B 与亲近的人争吵会引发孤独感，但是，一般说来，人们的关系若是通常处于什么状态，通过写出他们吃爽心食物的经历会降低他们的孤独感呢？一定不会是sad、shy或angry ，答案应该是secure （稳定的）。12.D 修饰essays 的所有格代词在人称与数上要与they 一致，所以their 是答案。13. C “eating food with family and friends” 是一种experience （经历），不会是一个accident （事故）、harm （危害）或model （样式）。很明显， experience 是本题的答案。14.A 文章中几次提到吃爽心食物有助于缓解孤独感。所以本题选eating 是很自然的。其他三个选项， exchanging （交换）、buying （买）或keeping （保留）若填入句子中，与后面的宾语chicken soup in the lab 连用，意思上说不通。15.D 本题的答案是connections。其他三个选项在意思上都不合适。
