Question

【題目】 If you dropped a piece of fruit on your computer keyboard, would you think about eating it again? What if you dropped it in the toilet? Bacteria(細菌) can live everywhere, even in some unexpected places.

If you eat at your computer, sneeze on your keyboard, or sit down to surf the Internet without first washing your hands, your computer keyboard could be bad for your health. According to the US National Research Centre, the average computer carries 400 times more bacteria than a toilet bowl(抽水馬桶) does.

Could one of the dirtiest things in your home be right in your hand? Yes. The TV remote control. It gets dropped on the floor, put on the sofa and everyone in the house holds it. Scientists found that about half of the tested remote controls carry the cold virus(病毒).

Don’t forget your toothbrush. Do you put it in the bathroom? Studies show that flushing(抽水沖洗) the toilet releases(釋放) bacteria in the air. Bacteria can remain in the air for at least two hours. They may pollute your toothbrush. You can find ways to solve this problem. Try to keep your toothbrush far from the toilet. Make sure that it is in an upright position after each use. It’s also important to change your toothbrush every three months.

Here are some other places to watch out for:

At home

The kitchen is one of the places with the most bacteria — more than the bathroom. Dishcloths and kitchen sponges(海綿) are great places for bacteria since they are always wet after being used. Try to make them dry.

At school

When you put your schoolbags on the floor or in the bus, many bacteria can live on the bottom(底部) of it. Try to clean your schoolbag often.

In public places

Escalator handrails(電梯扶手), shopping cart handles(推車手柄), public books and magazines are top bacteria carriers. That’s why the first thing to do when getting home is to wash your hands.

Yes, bacteria are everywhere. But don’t be too afraid to touch those things. Most of bacteriaare harmless. Just remember to wash your hands regularly. It is the most useful way to protect yourself from bacteria and viruses.

【2】題意：經(jīng)測試，有多少遙控器帶有感冒病毒？

根據(jù)原文第3段Scientists found that about half of the tested remote controls carry the cold virus可知，科學(xué)家發(fā)現(xiàn)，大約一半被測試的遙控器攜帶感冒病毒。故答案為About half of them.
