问题 共用题干Germs（细菌）on Banknotes
People in different countries use different types of money:yuan in China,pesos in Mexico,pounds in the United Kingdom,dollars in the United States,Australia and New Zeal-and. They may use different currencies,but these countries,and probably all countries,still have one thing in______(1):germs on the banknotes.
Scientists have been studying the germs on money for well over 100 years. At the turn of the 20th______(2),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______(3)one country. In a new study,Frank Vriesekoop and other researchers compared the germ populations found on bills of different______(4).
Vriesekoop is a microbiologist at the University of Ballarat in Australia. He led the stud-y,which compared the germ populations found on money______(5)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,______(6)those businesses often rely on cash.
Overall,the Australian dollars hosted the fewest live bacteria一no more than 10 per square centimeter. Chinese yuan had the______(7）about 100 per square centimeter. Most of the germs on money probably would not cause harm.
What we call“paper money”_________(8)isn't made from paper. The U. S. dollar,for ex- ample,is printed on fabric that is mostly cotton. Different countries may use different______(9)to print their money. Some of the currencies studied by Vriesekoop and his team,such as the American dollar,were made from cotton. Others were made from polymers.
The three______(10)with the lowest numbers of bacteria were all printed on poly-mers. They included the Australian dollar,the New Zealand dollar and some Mexican pesos.
The______(11)currencies were printed on fabric made mostly of cotton. Fewer germs lived on the polymer notes. This______(12)suggests that germs have a harder time staying alive on polymer surfaces. Scientists need to do more studies to understand______(13)germs live on, mon-ey—and whether or not we need to be concerned. Vriesekoop 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______(15)germs. We should wash our hands after touching it;After all,you never know where your money's been. Or what's living on it.5._________A: borrowed B: delivered C: designed D: gathered
选项 5._________
A: borrowed
B: delivered
C: designed
D: gathered
答案 D
解析 前文说了很多不同国家钞票的不同，最后一个转折，肯定是要说相同的地方。in common是固定搭配，意思是相同，共同。故选C项common。
选century最合理，意为20世纪之交。period(A项）, year(B项）或decade (D项）都不合逻辑。故选C项century。
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。故选B项within。
经过第四题选词的思索过程，本题很自然在different之后用countries，指不同的国家。故选A项countries。
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。故选D项gathered。
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。所以本题答案是A项because。
上一句中说澳元携带最少的细菌，本句与上一句是相对的，肯定是最多的，选A项most。
本句的句意是我们所说的纸币其实并不是由纸做的。所选的副词来修饰所说，给的四个选项分别是A项“相似地”；B项“简直不”；C项“轻微地”；D项“通常地”。所以选 D项usually合适。
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C项materials（材料、原料）是正确的。
前文说了不同国家的纸币携带的细菌数量不同，此处选B项货币最为合适。填入后全句意思就是：含细菌最少的三个国家的纸币……。故选B项c盯rencies。
the other＋名词表示“其他的……”。其他选项从语法上无法与the搭配。此句意为：其他纸币大部分是印在棉织物上的。所以选D项other。
本句前面两句讲述了细菌在什么样的介质上更容易存活。承接下来的应该是对之前的总结。本句四个选项的含义分别为A项“连接”；B项“参与”；C项“表述”；D项 “估计”。C选项比较合适，填入后句意为：前面的表述说明细菌在聚合物表面不易存活。故选 C项expression。
科学家要研究细菌如何在纸币上存活。所以本句选how。 if(A项）, where(B项）, when(D项）都与文意不符。故选C项how。
on different types of bills（在不同的纸币上）说明是比较关系，所以本句要选compare“比较”。故选B项compare。
纸币和细菌的关系肯定是纸币携带细菌。“避免”(A项）、“杀死”(B项）和 “选择”(D项）细菌都不正确。所以选C项carries。
