参考解析
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。
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。
