Question

The Healthy Habits Survey (调查) shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.

1. How many times did you brush your teeth yesterday?

Finding: A full 33% of seniors brush their teeth only once a day.

Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.

2. How many times did you wash your hands or bathe yesterday?

Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.

Step: We touch our faces around 3,000 times a day-often inviting germs (病菌) to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with hot running water and soap for 20 seconds.

3. How often do you think about fighting germs?

Finding: Seniors are not fighting germs as well as they should.

Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

试题分析：美国人的健康生活习惯怎么样？最近一项调查显示，只有1/3的美国人生活习惯良好。在刷牙、洗手、灭菌的调查中，许多人并没有养成良好的生活习惯。

1.细节理解题。由“A full 33% of seniors brush their teeth only once a day.”可知有大约1/3的人每天只刷一次牙。许多人的生活习惯并不算好，A项不对。老年人每星期洗澡小于3天，B项不对。人们没有像应该的那样抗菌，C项不对。故选D。

2.细节理解题。由“nearly 30%wash their hands only 4 times a day-half of the number doctors recommend.”可知，每天洗4次手只达到了医生要求的一半，即每天应洗8次手。故选D。

3.细节理解题。由“Do you know it is not your toilet but your kitchen sponge (海绵) that can carry more germs than anything else? ”可知厨房里的海绵可以携带比厕所更多的细菌。故选C。

4.推理判断题。A项“指南”，B项“受欢迎的杂志”，C项“书评”，D项“官方文件”。根据文章内容推断应为杂志，故选B。
