Waste sorting（垃圾分类） is a big matter worldwide． In order to sort the rubbish properly and protect the environment， people in different countries are using different methods to sort their waste．

UK A UK company invented a "smart bin" to help with waste sorting． People just need to drop their waste into the bin（垃圾箱）． A camera and sensors（感应器） in the bin can tell what type of rubbish it is and correctly sort it． The bin also compresses（压缩） the waste so it takes up less space．

South Korea South Korea is using a method called "Pay For Your Waste" to encourage its people to reduce food waste． When throwing away rubbish， people have to separate their food waste from their other rubbish and put it in a bin． The smart bin then weighs the food． People have to pay for their food waste by scanning（扫描） a barcode（条形码） on the bin． If they throw away more rubbish， they will pay more．

Japan Japan is leading the world in waste sorting． They sort waste so carefully that even plastic bottles and their caps go into different bins． Different types of paper products have their own bins．

China China is improving its waste sorting efforts． Shanghai has worked with Alipay to create a "green account（账户）"service for its residents（居民）． The city is asking all of its residents to sort their waste into four groups： wet， recyclable， harmful and dry．

Teeth are important part of our body． Everyone should brush his or her teeth every day． Learning how to take care of teeth is very important．

The importance of brushing teeth

If you eat and do not brush your teeth， pieces of food that stick to your teeth can cause problems． The food can damage （破坏）your teeth． Then germs （细菌）can get into your teeth and make them decay （腐烂）．

It is important to brush teeth every day． You should get a checkup from your dentist every year． Trying not to eat food that has a lot of sugar， such as candy and soft drinks， helps to protect teeth．

The proper ways of brushing teeth

Do you know that most people do not brush their teeth in the right way？ Follow the methods below and they will help you keep your teeth healthy， clean and beautiful．

♦Replace your toothbrush every few months．

♦Clean two or three teeth at a time． Brush the front of your teeth with a circular motion （运动）and clean the backs of your teeth with up and down motions．

♦Use a gentle back and forth motion to clean the tops of your teeth where you bite （咬）into food．

♦Don't forget to gently brush the top of your tongue （舌头）from back to front．A lot of germs live there．

♦Take at least 2 minutes to brush your teeth．

Your body is special﹣no two people in the world are the same．Although you are different from everyone else，you have exactly the same body parts as the people around you，doing different jobs that keep all of us alive．

What is inside my head ？

Your head holds the most valuable part of your body in it﹣your brain．As you are reading，your eyes send pictures to your brain which makes meaning from what you see．Your brain heIps you to remember and think，and makes sure your body is doing what it should do．

What is my skin for ？

Your skin covers your body．In most parts of your body，the skin is just as thick as 0.5cm．If you cut your skin，it will have a quick cure（治愈）and stop viruses（病毒）from getting into your body．Your skin also helps you feel the heat and coldness of the environment around you．Hair grows from inside the skin．When you feel hot，extra heat comes out through your skin．As a result，your body temperature drops．

How do I move ？

Muscles（肌肉） are found in most parts of your body． They work with your bones to help you move﹣ whenever you cry or smile， eat or speak， walk or dance， etc．

What does my heart do ？

Your heart is a very special muscle． It is a little bigger than your fist（拳头）and grows bigger as you do． If you place your hand on your heart， you will feel your heart beating which pushes blood to move around your body．
