　　Germs on Banknotes

　　People 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 isn't 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.Or what's living on it

　　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。
