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.

參考譯文：
經常洗手能有效減少細菌傳染。美國疾病控制與預防中心公佈稱：洗手是預防傳染病最有效的方式之一。每次洗手時，你或許會發現自己洗手的次數並不是那麼頻繁。一份報告顯示：94%的美國人使用過衛生間後會洗手，但據一項公共廁所相關調查發現，使用過衛生間後洗手的成年人只有68%。
為什麼要洗手?因為細菌是肉眼所看不到的。有的細菌還會引發嚴重甚至致命的疾病。正確的洗手方式可以很大程度上減少細菌的傳播。當你用手觸控鼻子，嘴巴或者外傷時，可致病細菌便會藉機進入體內。有的細菌為打破抗生素這一“屏障”會不斷繁殖。雖然說勤洗手是醫護人員的硬性要求，但是每個人都應該有經常洗手的衛生保健意識。
如何正確洗手是非常重要的，尤其是需要消除手上細菌的時候。當然，快速沖洗是遠遠不夠的。洗手時應該使用肥皂和流動的溫水。徹底清洗手部面板，包括手腕、手掌、手背、手指和指甲。用力擦洗雙手10-15秒。洗完之後，可以用一條幹淨的或者一次性毛巾輕輕拍幹多餘水分。最後擦拭護手霜，防止肌膚乾燥。
19. 調查發現洗手存在哪些問題?
20. 如果不洗手，細菌是樣進入人體的?
21. 洗手時應該使用什麼樣的水?
22. 文章中提到的'與洗手相關的內容有?
習題解析：
【小題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，只有大約三分之二的人在使用過公共衛生間後洗手。因此答案為選項 D。選項A和 B不屬於調查的新發現，排除;雖然短文中也提到有 94%的美國人使用過衛生間後洗手，但後面提到的 68%的人是限定在公共衛生間範圍內，所以不能表明美國人說謊，排除選項 C。
【小題20】短文中明確提到 Disease-causing germs can enter your body when your unwashedhands touch your nose, mouth, and open wounds，由此可知，選項 B為答案。
【小題21】短文中明確指出，洗手時應該使用 warm, running water，而由水龍頭裡流出的溫水符合這一表述。因此答案為選項 C。
【小題22】短文最後提到要徹底把手的各部位洗乾淨，所以答案為選項 A，同時排除選項 D;文中提到的搓手是至少 10 到 15 秒，而不是分鐘，排除選項 B;擦乾時，最好是輕拍，而不是揉搓，排除選項 C。
