Always use soap to wash your hands. After turning on the tap(水龙头) and wetting your hands, you can rub(搓) your hands with soap(肥皂). Soap may not kill all the germs but it can wash away the oil on your skin. As the oil is washed away, the germs will leave your hands and go away.
You should wash your hands for 15－20 seconds. How do you know the length of 15－20 seconds? You can sing the ABC Song. By the time you get to the last note, your hands will be clean!
Rub your hands together. You can use one hand to rub the back of the other hand and then switch hands. You also need to rub between your fingers. Don’t forget to rub under and around your fingernails(指甲).

2. A 【解析】根据“You can sing the ABC Song. By the time you get to the last note, your hands will be clean!”可知，这里指唱完ABC歌的最后一个音符，洗手时间就够了，“note”在此处表示“音符”。故选A。
