(D)

Do you often grab something to eat after you get a phone call? Do you often sleep after playing games on your phone? Mobile phones are a great way to kill time and get in touch with friends.But they are also great places for bacteria(细菌) to live.

A US study showed that there are as many bacteria on your mobile phone as on your toilet seat.The study said about 2700--4200 units of bacteria were found on each phone scientists tested.In drinking water, the limit is less than one unit per half cup.

In fact, mobile phones are not the only dirty things around you.There are many things that carry a lot of bacteria you may not pay any attention.

Toothbrushes can be dirty, especially when you put them close to the toilet.Studies show that every time you flush(抽水冲洗)the toilet, bacteria can remain in the air for at least two hours.These bacteria may pollute your toothbrush.It is better to put your toothbrush far form the toilet and make it in upright position after each use, It is also important to change your toothbrush every three months.

Everyone loves money, but no one loves the bacteria on it.From the supermarket to someone's home, a large number of bacteria live on every note.US scientists found anywhere from 126,000 to 135,000 bacteria on a single bill.The way to deal with this problem is to try to wash your hands as often as possible.

Funnily enough ,the very sponge( 海绵 )that makes your dishes clean is really the dirtiest of them all.Sponges stay wet long after being used, which makes them more likely to carry bacteria.Wash the sponge carefully after each use.Microwave(用微波炉加热)the sponge for 60 seconds.The high heat can Sponges kill most bacteria.
