Passage Two
Hand washing reduces the spread of germs fromone person to the next. According to the ers for Disease Control and Prevention, handwashing is one of the most important means ofpreventing the spread of infection. If you trackwhen you wash your hands you may find it is not as often as you think. (19) A recent surveyfound that 94% of Americans say that they always wash their hands after going to thebathroom but observations in public restrooms show that only 68% of adults did so.
Why should you wash? Germs are so small that you cannot see them. A few of them can causeserious and life-threatening diseases. Washing your hands correctly greatly reduces thechances of spreading germs. (20) Disease-causing germs can enter your body when yourunwashed hands touch your nose, mouth, and open wounds. Some of those germs may havechanged to protect themselves against an antibiotic, which is called antibiotic e your health care providers have a professional responsibility to wash their hands, it isimportant that everyone make hand washing a personal priority.
How you wash your hands is important, especially when it comes to eliminating germs. Justwashing them quickly is not enough. (21) When you wash your hands: Use soap and warm,running water. (22) Wash all surfaces thoroughly, including wrists, palms, back of hands,fingers and under the fingernails. Rub hands together for at least 10-15 seconds. When drying,use a clean or disposable towel if possible, and pat your skin rather than rubbing. Apply handlotion or cream after washing to soothe your skin and help prevent drying.

参考译文：
经常洗手能有效减少细菌传染。美国疾病控制与预防中心公布称：洗手是预防传染病最有效的方式之一。每次洗手时，你或许会发现自己洗手的次数并不是那么频繁。一份报告显示：94%的美国人使用过卫生间后会洗手，但据一项公共厕所相关调查发现，使用过卫生间后洗手的成年人只有68%。
为什么要洗手?因为细菌是肉眼所看不到的。有的细菌还会引发严重甚至致命的疾病。正确的洗手方式可以很大程度上减少细菌的传播。当你用手触摸鼻子，嘴巴或者外伤时，可致病细菌便会借机进入体内。有的细菌为打破抗生素这一“屏障”会不断繁殖。虽然说勤洗手是医护人员的硬性要求，但是每个人都应该有经常洗手的卫生保健意识。
如何正确洗手是非常重要的，尤其是需要消除手上细菌的时候。当然，快速冲洗是远远不够的。洗手时应该使用肥皂和流动的温水。彻底清洗手部皮肤，包括手腕、手掌、手背、手指和指甲。用力擦洗双手10-15秒。洗完之后，可以用一条干净的或者一次性毛巾轻轻拍干多余水分。最后擦拭护手霜，防止肌肤干燥。
19. 调查发现洗手存在哪些问题?
20. 如果不洗手，细菌是样进入人体的?
21. 洗手时应该使用什么样的水?
22. 文章中提到的'与洗手相关的内容有?
习题解析：
【小题19】短文中提到 A recent survey... observations in public restrooms show that only 68%of adults did so，由此可知，只有大约三分之二的人在使用过公共卫生间后洗手。因此答案为选项 D。选项A和 B不属于调查的新发现，排除;虽然短文中也提到有 94%的美国人使用过卫生间后洗手，但后面提到的 68%的人是限定在公共卫生间范围内，所以不能表明美国人说谎，排除选项 C。
【小题20】短文中明确提到 Disease-causing germs can enter your body when your unwashedhands touch your nose, mouth, and open wounds，由此可知，选项 B为答案。
【小题21】短文中明确指出，洗手时应该使用 warm, running water，而由水龙头里流出的温水符合这一表述。因此答案为选项 C。
【小题22】短文最后提到要彻底把手的各部位洗干净，所以答案为选项 A，同时排除选项 D;文中提到的搓手是至少 10 到 15 秒，而不是分钟，排除选项 B;擦干时，最好是轻拍，而不是揉搓，排除选项 C。
