任务型阅读 Do you clean your school desks every day? If not, then maybe it's about the time for you to get started. Keyboards, computer mice and telephone dials are infected (polluted) with lots of germs(细菌), according to scientists from the University of Arizona, the US. The study suggests that office equipment should be regularly cleaned. “Desks are in fact germs' cafeterias(自助餐厅),” said Charles Garbage, a biologist who took part in the study. “They are breakfast bars, lunch tables and everything else.” The desks at your school are probably not different. The scientists found that telephones in workplaces have almost 4,000 germs/cm2, keyboards 500 and computer mice around 250. The office as a whole contains 4, 750germs/cm2. When some people catch a cold or flu, they leave germs on the surfaces(表面) they touch during the day. Some flu germs can live on the surface for up to 72 hours, so the germs can easily move to other people. If you're ever wondered why everyone catches the germs when only one student has a cold, now you know the answer. Experts in the US last month warned about the spread(传播) of the germs during flu seasons. They reminded Americans to cover their noses and mouths while sneezing, often wash their hands and clean their office desks.Hand washing is the most important.
