A new rubbish sorting system (垃圾分类系统) has been put into use in Fangchengyuan Community in Beijing. Local people not only sort their rubbish, but also put QR codes (二维码) on it.

    "When the rubbish is collected and the codes are seen, I will get reward points to exchange for small gifts and even some money," one of the local people told reporters. "It's really creative and encouraging."

    This smart system has been carried out in 350 communities in Beijing. The capital of China has joined a list of cities in the country that take action to support rubbish sorting. For example, Shenzhen and Shanghai have made laws to punish people and organizations for not sorting rubbish correctly.

    China produces quite a lot of rubbish every year. Much of the rubbish is buried (填埋) in soil or burned without being sorted. Landfills (填埋场) take up a lot of land and have a risk of polluting the soil and water nearby. And burning rubbish can produce harmful gases. Through rubbish sorting, we can reduce the use of landfills and air pollution.

    What's more, rubbish sorting saves resources, which could bring economic benefits (经济利益). For example, a ton of waste paper can be reused to make about 850 kg of paper, saving 17 trees and 50 percent of water. Because of the benefits, some countries have developed successful sorting systems.

    Japan has a strict and detailed system. When people throw away a water bottle, the cap, the wrapper (包装纸) and the bottle itself have to go into three different bins. Every year, families receive special rubbish sorting timetables and directions from their local governments. They are advised to follow the timetables and directions when they throw away rubbish.

    In Australia, every family is provided with three rubbish bins—the red lid (盖子) bin for "general waste" like food and plastic bags, the yellow lid bin for "recycling" like steel and glass, and the green lid bin for "green waste" such as grass and leaves. On the streets, the bins are printed with pictures of the things that are allowed inside. It makes recycling quite easy.

Molly and David live in a big house with their parents. Molly is twelve years old and David is fourteen years old. They are both middle school students in Zhonghua Middle School. Every morning, they get up at 6:45 and have a big breakfast. Molly eats eggs, bread and corn and David eats sandwiches and eggs. Molly usually drinks milk and fruit juice and she likes orange and apple juice very much. David always drinks cola and coffee（咖啡）. His mom tells him that it is not good for his health. 'For lunch, Molly usually eats healthy food like rice, chicken, fish and pork（猪肉） with some vegetable soup but David'only likes chicken and fish. He doesn't like green vegetables or fruit at all. When he goes shopping with his mom; he buys a lot of food to eat and he likes Latiao very much. Sometimes, his mom is not happy about him. 

Since August，driverless taxis can run on roads in cities including Wuhan，Chongqing（科技） into reality，sad China Daily.

Why do we develop self—driving cars？

Self—driving cars give us many benefits（好处）.They use computers to sense（感知） the things around them and make better use of space.This means fewer traffic jams and better parking of cars.For disabled（残疾的），self—driving cars can also help them get around more easily.By using computers，they can avoid unskilled，careless or drunk driving and so on.This can cut down 90 percent of road accidents，said the website TechDim.

Is self—driving cars totally safe on roads？

Self—driving cars can't react（反应） as fast as a human driver could if something unexpected（意料之外的） happens.Also，it is difficult for self—driving cars to see clearly.The car's computer could also get hacked（非法入侵），making it crash（碰撞），technology companies are working on these problems.

Balancing(平衡) your diet(饮食) is important. {#blank#}1{#/blank#}Let me tell you.

{#blank#}2{#/blank#}If you don't have time to sit down and have a healthy breakfast, try vegetable juice before you go to school. This is better than coffee.

Eat less salt. {#blank#}3{#/blank#}So eat less or give them up. Stay away from foods with too much fat. You can eat vegetables, fruits, fish and chicken. {#blank#}4{#/blank#}For example, you can eat

chicken hamburgers instead of(而不是) beef hamburgers.

We all know that regular(有规律的) physical exercise is good for a girl's body, mind and spirit. The Women's Sports Foundation found that except having fun and staying healthy, there are many more benefits(益处) to girls from exercise. 

Girls who play sports do better in school. You might think that sports will take up all your study time. But research shows that girls who exercise do better in school than those who don't. Exercise improves learning, memory and concentration(专注) which can give active girls an advantage in the classroom. 

Girls who play sports learn teamwork. Being a team player to work with coaches, trainers and teammates to win games is great practice for success later in life. It can make working with others and solving problems easier, whether on the field or in the workplace. 

Sports have hidden health benefits. Some benefits of sports are clear — like improving physical fitness and keeping a healthy weight. And girls who play sports are also less likely to smoke and have a reduced chance of getting breast cancer(乳腺癌) later in life. Sure, you can get these benefits from any type of exercise. 

Playing sports build up self-confidence. Girls who play sports feel better, both physically and mentally. It helps you build up confidence as you see your skills improve. 

Exercise can reduce pressure. Pressure is a big part of life. Playing sports can help you deal with it since exercise is a natural mood-lifter and a great way to reduce stress and light depression(抑郁). 

Do you ever feel like there's not enough time in the day? That time is somehow racing away from you, and it is impossible to fit everything in. But then. you step outside into the countryside and suddenly everything seems slower, more relaxed, like time has somehow changed. It's not just you-recent research showed nature can control our sense of time.

Richardo Correia, the researcher at the University of Finland, found that being in nature may change how we experience time and perhaps, even give us the sense of time abundance(充裕). Correia compared people's experiences of time when they performed different types of tasks in cities and natural environments. It showed that people reported a sense of expanded time when they were in nature compared to when they were in cities. For example, a walk through the countryside felt longer than a city walk of the same distance.

It's not just our sense of time in the moment which appears to be changed by the natural world, and it's alsoour sense of the past and future. Earlier research shows that spending time in nature helps to move our focus from44the immediate(目前的) moment towards our future needs. So rather than focusing on the stress of the demands(需求)on our time, nature helps us to see the bigger picture. This can help us focus on what's important so that we meet our long-term goals. This is partly because spending time in nature appears to make us less impulsive(冲动的)，enabling us to think more about future benefits instead of wanting immediate ones.
