    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.

    On a very hot day, it is hard to know what to do to feel good. If you run around, you may feel sick in your stomach. However, if you just sit quietly and do nothing, you may feel bored. Are there things you can do to feel good and have fun when you're hot?

    Perhaps playing in water is a good choice to make you cool down. Taking a cool bath or shower, or even washing toys in a pan of cool water can also make you feel good on a hot day. Besides, you can read stories or paint in front of a fan. You don't need to move your body very much. These are just some of the cool things to do on a hot day.

    In addition, it's important for you to drink water. On hot days, you can lose about 16 glasses of water in one day. If you feel thirsty, you are already short of water. So don't wait for thirst before you start to drink. You should try to drink as much water as you lose every day. Mixing a little fruit juice into your water is a fun way to help you drink plenty of water.

    The food you eat also makes a difference in how you feel in the heat. Cold foods such as ice cream and drinks with some ice can cool down your bodies. Fruits and vegetables are also helpful to stay cool in hot weather. So plan a healthy menu for a hot day—one that doesn't need any cooking.
