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.

In the warm waters near an island, a small group of dolphins comes up for air. The dolphin in the front is Mother Dolphin.

Mother Dolphin will 1 Baby Dolphins for a long time. She'll stay beside her babies until they grow up. Baby Dolphins are very playful. They can swim well and love to push their mother softly. After playing so much, they get tired. At night, they 2 just below the surface of the water with Mother Dolphin.

Dolphins may look like fish, 3 they aren't really fish. Dolphins have their own underwater language of sounds. They use these 4 to communicate with each other.

Dolphins always travel in small groups to 5 themselves against their enemies, like the shark. They can live for many years. Some dolphins live up to 35 years in the wild.

Bill was a boy of 15. His parents went to gambling (赌博) day and night. 

Nobody cared about him. He always failed in his exams. So his teachers didn't like him, nor did his classmates play with him. Bill often slept in class because his heart was not in school. He almost gave himself up. 

One day, Miss Jones, a new teacher, came to Bill's class. She was a smiling, beautiful woman. Bill was in love! For the first time in his young life, he couldn't take his eyes off his teacher. 

It was Miss Jones' class. She was asking a question. "I'd like the smartest boy to answer my question. " Then she said loudly, "Bill, please!" Bill was surprised. And he stood up without a word. 

"Just try it! I believe you can!" After school, Miss Jones had a long talk with Bill. She told him that she cared about him and believed in him. 

Bill thought a lot that evening. From then on, he arrived at school on time every day. Miss Jones helped him with his homework in the afternoon. She even cooked delicious food for him. She told Bill, "Nothing is impossible if you put your heart in it. "

Later, Miss Jones gave another exam. Bill did it with all his heart. He was very excited to find that he had passed the exam. Now Bill discovered that not only could he learn, but he could do it well. A change took place in Bill's heart. 

You see, one teacher saved one boy. It's simple, really. 

A new study has shown how the color of a bowl can influence the taste of the food it holds. 

Although it is hard to say what a picky eater (挑食的人) is like, the type may include people who have a limited diet, who have strong likes or dislikes for certain food, who require food to be prepared in a special way, who aren't willing to accept new food, or who show signs of all these features. 

According to this new study, food was put into two groups in red, blue, or white bowls. While the color made no difference in taste for non-picky eaters, the picky. eaters reported changes in their taste senses-based-on-the color of the bowl being used. Snacks in red and blue bowls were thought to have more salt than those in white bowls, while snacks in red bowls were less pleasant than those in the other bowls. 

 "This knowledge can be useful for those who want to try more kinds of foods," says Lorenzo Stafford, a psychologist from the University of Portsmouth in the UK. "For example, if you want to encourage a picky eater to try some bitter (苦的) vegetables, you can try to put them on a pink plate or in a yellow bowl, because this can give him or her a sweet feeling."

At first it may seem strange that a bowl color can influence the taste-of food, but the research before has shown how light and music can influence eating habits. All of our senses are connected, including taste. 

 "This new study can help in treating food neophobia--the unwillingness to try new food, "the team of the study says, and further studies will be required to find out more relationships between colors and foods. 

 "Through further studies, maybe we can decide ways to help actively influence a person's diet, and as a result, their health in mind and body." says Stafford.
