凡事过犹不及,洗手洗得太多太频繁,不仅不能预防细菌还有可能滋生细菌,这是为什么呢?下面的新托福考试阅读练习资料会给我们解答。

Most people believe that regular hand-washing is the best way to prevent infections. And they’re right: hand-washing does prevent certain infections, but too much washing can actually help some infections along.What’s going on?

Right now, there are millions of bacteria from hundreds of different species happily residing on your hands, not to mention your teeth, gums, eyes and ears. These bacteria are either transients or residents.

Washing your hands helps remove transient bacteria that are just visiting from foreign places like the sink, doorknob and even other people’s hands. Washing shouldn’t remove your hands’ own resident bacteria,though.

While it’s hard to imagine your hands as a bacterial homeland, these residents are perfectly normal and are important in maintaining your health. They help prevent transient bacteria from settling in, and each resident keeps other residents from overpopulating.

If you scrub your skin too frequently, especially with anti-bacterial soap, you could upset resident bacteria, leading to the overpopulation of certain species and local skin infections. Scrubbing away residents might also let transients move in and cause disease. Finally, over washing could break down the skin itself. This allows harmless skin residents to go beneath the skin, where they can become dangerous transients.

So, while a good wash with soap and water is still a great idea, overwashing might lead to some unpleasant symptoms, not to mention inflamed and unsightly hands.

以上就是这篇托福阅读材料,同学们可以积累其中的词汇及优美句式,找到托福阅读段的主题句,了解托福阅读的几个出题点。托福阅读训练是个长期的过程。大家如果每天做几篇阅读,坚持下来,一定会有不小的进步。预祝大家能有一个好的阅读成绩。
