阅读材料,完成下列要求。

材料一:明德正德以后,欧洲殖民者东来,中国优良的手工业品不断地运往欧洲市场,欧洲殖民者为了支付与中国贸易的差额,运进了大量的白银,这就使正德以后的银币使用较前普遍,到了嘉靖四十一年,全国班匠普遍征银的客观条件已经成熟,政府就废止了双规办法,一律以银代役。该年工部题准:“行各司府,自本年春季为始,将该年班匠(工匠)通行征价类解,不许私自赴部投当.仍备将各司府人匠总数查出,某州县额设若干名,以旧规四年一班,每班征银一两八钱,分为四年,每名每年征银四钱五分……”——摘编自张帆《中国古代经济简史》

材料二:淘金人纷纷涌向德国境内的金银矿山,尽管许多矿山已经资源枯竭,但他们仍然拼命挖掘。1460~1530年间,中欧的银产量增加了5倍以上。除了争取更多的对外贸易顺差和搜刮金银器皿,并把它们熔化及鼓励开采金银矿外,政府还设法让金银铸币的成色降低。16世纪前半期,英国就采取了这种做法,使英国硬币的含银量在短短的8年内(1544~1551年)跌到接近原来的四分之一左右。这一切正如恩格斯在《论封建制度的瓦解和民族国家的产生》一文中指出:“在15世纪末,货币已经把封建制度破坏和从内部侵蚀到何种程度,从西欧在这一时期被黄金热所迷这一点看得很清楚。”——据厉以宁《资本主义的起源》

    October 15th is the Global Hand washing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap(肥皂). For example, donators(捐献者)will give 150,000 bars of soap to schools in Ethiopia.

    Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.

    Global Hand washing Day is the idea of the Public-Private Partnership for Hand washing with Soap. Partners include the United Nations Children's Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(细菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.

    The Partnership for Hand washing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Hand washing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(传染)themselves by touching their eyes, noses or mouths. Then they can infect others.
