Everyone likes living in a clean and comfortable environment. If the environment are bad, it will affect our body, and make us not feel well. Sometimes we may be terribly ill. At that time we

don’t want to work, and we have to stay in bed and rest at home. So the environment is very

important to us.

It’s germs that makes us ill. There are germs everywhere, They are very small and you

can’t find them with your own eyes, but you can see them with a microscope. They are very small

and there may be hundreds of them on a very small thing. Germs can always be found in dirty

water. When we look at dirty water under the microscope, we shall see them in it. Germs can also be found in air and dust. If you cut your finger, some of the dust from the floor may go into it, and you will have much pain in it. Sometimes the germs will go into all of your body, and you will

have pain everywhere.

To keep us healthy, we should try to our best to make our environment become cleaner and

tidier. This needs us to act together.

Most of us have now heard about the plane crash of German wings Flight 9525. After taking off from Barcelona, Spain, the plane crashed into the French mountains on its way to Düsseldorf, Germany. Immediately, it caused shock and also questions. How do we find out what happened?

There is one piece of equipment that is the key to discovering the mysteries of a crash: the black box. On an airplane, there are actually two black boxes: the flight data recorder (FDR) and the cockpit (驾驶员座舱) voice recorder (CVR). FDR holds altitude levels information while CVR keeps conversations in the cockpit and radio conversations with air traffic control.

Australia was the first country to require airplanes to have flight recorders—it wasn’t until 1976. Since then almost every country on Earth follows this rule.

So what did the black boxes uncover about the Germanwings Flight 9525? By using their data, it is believe that the crash was caused by the co-pilot on purpose.

In the event of a tragedy, the truth must become clear. This is why black boxes play such as important role in uncovering the truth.
