资源简介

A

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.

这是一篇说明文。健康习惯调查显示,只有大约三分之一的美国老年人有正确的习惯。文章介绍了一些发现和专家建议。

1题详解】

推理判断题。根据“Finding: A full 33% of seniors brush their teeth only once a day.”可知,大约三分之一的人每天只刷一次牙。故选D项。

2题详解】

细节理解题。根据“And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.”可知,将近30%的人每天洗4次手,只有医生建议的一半,所以医生建议每天要洗8次手。故选D项。

3题详解】

推理判断题。“Be aware of germs. Do you know it is not your toilet but your kitchen sponge that can carry more germs than anything else?” 注意细菌。你知道吗?不是你的马桶,而是厨房里的海绵,比任何东西都更容易携带细菌。可知,CA kitchen sponge can carry more germs than a toilet.(厨房里的海绵比厕所里的细菌还多。)是不正确的。故选C
