题目内容
12.Your smart phone can do a lot of things.It can call people.It connects to the Internet.It enables you to play fun games.But there is a dark side-it might also spread diseases.This may be hard to believe,but scientists reached this conclusion after they tested eight random cell phones from an office in Chicago.All the tested phones showed high numbers of bacteria,with about 2,700to 4,200 units on each phone.In drinking water,the healthy limit is less than 1unit per 100ml (毫升) of water.
Although computers,keys and pens all carry bacteria,our smart phones get far dirtier.They touch a lot of things,including our hands and the inside of our pocket or purse.We take them almost everywhere:the bus,the subway and who hasn't played smart phone games while sitting on the toilet?
What's even worse is that after the phone returns from its dirty trip,it then spends most of its time cozying up to our faces.You don't think about how often you touch your phone to your face,do you?Our noses,mouths and ears are all warm and rich in grease (油脂),an environment that bacteria really like.
Compared to traditional keyboard,touch screens spread bacteria more easily to hands.An expert in Australia warned that playing with iPads and iPhones at Apple stores is a health risk.
There is one simple and reliable way you can reduce the bacteria on your phone's surface:wash your hands regularly.So how do you keep your smart phone clean?Alcohol is effective when used to kill bacteria from the back and side of your phone.
