牛津深圳版 2019-2020 学年九年级上册期末备考--D 篇阅读

一

Almost everyone has dropped some food on the floor and still wanted to eat it. If someone saw you drop it, he or

she might have shouted, “ 5-second rule!” This so–called rule says food is OK to eat if you pick it up in five

seconds or less. But is that true?

Professor Anthony Hilton from Ashton University, UK, tested the rule with his students. They found that food

dropped for five seconds is less likely to contain bacteria(细菌) than if it sits there for longer.

For the study, Hilton and his students tested a lot of foods——bread, pasta, cookies and candy—to see how

much bacteria they had when they made contact with the floor. They allowed the food to lie on the different types

of flooring—carpet(地毯), laminate (复合地板) and tile(瓷砖) — for three seconds to 30 seconds.

Not surprisingly, the longer the food was on the floor, the more bacteria it had. And the type of floor where the

dropped food landed had an effect. Bacteria are least likely to transfer(转移) from carpet, while they are most likely

to transfer laminate or tiled surface after more than five seconds.

The study also found that the wetter the food, the more likely it was to pick up bacteria. Although most people

are happy to follow the 5-second rule, eating food dropped on the floor still carries an infection( 感染) risk. “It very

much depends on which bacteria are on the floor at the time.” Hilton told Forbes.

According to a new survey, students’ safety has become a big problem. Nearly 50% of the students say they

are worried about robbery on the way to and from school. Now in many big cities in China, some schools have

taught an unusual lesson: self-protection. Students like this lesson because there are no exams or boring classes.

And they can learn how to save lives and know how to stop danger before it really happens.

Chen Haoyu, a teacher at Beijing No. 25 Middle School, gives young students advice on how to deal with

danger.

If you are robbed. Keep calm. If you can not cry for help or run away, give the robber your money. Try to

remember what the robber looks like and tell the police later.

If you are in a traffic accident.

If a car hits you, you should remember the car number. If it is a bicycle, try to call your parents before you let the

rider go. This is because you don’t know how seriously you are hurt.

If it is raining hard and there is lightning.

Don’t stay in high places and stay away from trees.

When there is fire.

Get away as fast as you can. Put wet things on your body and try to find an exit. Do not take the lift.

If someone is drowning(溺水).
