Everyone likes living in a clean and comfortable environment. If the environment(环境) 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(微生物) 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（显微镜）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（灰尘）. 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 bodies， and you will have pain everywhere.

    To keep us healthy， we should try our best to make our environment cleaner and tidier. This needs us to work together.

    One day a little boy came into a fruit shop. He had five dollars and wanted to buy some apples. He said to the shop owner,“Give me $5 worth of apples, please.”

    When the shop owner gave him the apples, the boy counted them and felt very surprised. Then he said:“Last Friday, my mother bought apples here for $5, too. Why did you give me fewer apples?” “Don't ask questions, boy. I have no time for questions.”

    “Excuse me, sir.” said the little boy, “but…”

    “It is all right, my boy,” said the shop owner, “Don't you know? The fewer apples you get, the less fruit you will have to carry.” “All right.” said the boy and he gave $4 to the shop owner. He was just going to leave the shop when he heard the words:“Come back! You must pay me $5.” But the boy replied: “Don't you know? The fewer dollars you get, the less money you will have to count.”

    We can see many people riding shared bikes in China now.

    Bike-sharing helps people to borrow a bike from one place and return it at another place easily.

    This kind of bike has GPS or Bluetooth on it. You must have a smart phone if you want to use it. First, you have to download (下载) an APP on your smart phone. Then what you need to do is to find a nearest bike through the APP, scan (扫描) the QR code on the bike and you will get the bike.

    Then you can enjoy your trip. What's more, you can easily find one and don't have to worry about where to park it. Every hour you ride, you need to pay only one yuan. It doesn't cost so much, does it?

    Science changes our lifestyles. Bike sharing makes our life easier. And we also hope that people can not only enjoy it but also put it to good use.
