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

答案與題解:
1.B 冒號后面說的是各國使用錢幣的名稱:“yuan in China ，pesos in Mexico，pounds in the United Kingdom ，dollars in the United States，Aus往'alia and New Zealand” ，所以填人的詞必 定與這些錢幣有關(guān)，而且應該是錢幣的總括詞。因此選 money 最為恰當。coins 是“硬幣”，cheques 是“支票” ，loans是“貸款”，它們都不會是答案。
2.A 本題的句子說的是:雖然各國使用的紙幣各不相同，它們有一個共同點，那就是紙幣上 有病菌。四個選項中 different 是答案。
3.D 選century 最合理。選 anniversary (周年)，year (年)或decade都不合邏輯。
4.C 本段第二句提供了解答本題的線索。Frank Vriesekoop 的研究與以前的科學家的研究不同，他比較了各國錢幣上的病菌數(shù)量， 在他之前的科學家的研究范圍局限于一個國家的紙幣。四個選項中只有 within 表達“在(一個國家)里”的意思。
5. A 經(jīng)過第四題選詞的思索過程，本題的形容詞很自然會在 different 之后用 countries，指不同的國家。
