It's a wonderful, warm summer day without a coud in the sky. You're outside, and you can feel the sun's heat on your skin. Do you know what else you are feeling? You're feeling the sun's energy! Without it, the earth would be a cold, dark, lifeless place The sun's radiation(辐射) gives us light and heat energy.

 The Sun's radiation can be harmful to us as well. We can't see it, but ultraviolet(紫外线) radiation comes from the sun along with heat and light. You can not see ultraviolet radiation, but it influences our health. Ultraviolet radiation is what burns our skin.

 Ultraviolet radiation has three parts: ultraviolet radiation A, ultraviolet radialion B, and ultraviolet radialion C. Waves of ultraviolet radiation  A and B may cause harm to our body when we get sunburned. The harm to our body can give us skin cancer(皮肤癌) and cause other health problems.

 You can help to protect yourself from ultraviolet radiation by wearing sunscreen(防晒霜), sunglasses and hats.

 Try to stay out of the sun when it is especially strong .You can find out ultraviolet radiation levels by watching the weather report on television.

    When you are travelling by plane, there are some passengers you just don't want to have next to you.

      ①  

    Perhaps you normally like them , but when you are sitting next to them on a plane it is a different thing. They usually spend all flight moving around and dropping their toys on the floor, and when they are drinking their orange juice ,it ends up on your trousers. Then they decide they want to play with you. So you can't have the little sleep.

      ② 

     You can realize this type as soon as you sit down. They immediately start talking about the plane , or the weather, or they ask you a personal question. It is very difficult not to talk to these people . You'll probably have to keep talking until the plane landed.

      ③  

    These are the people with white faces who sit down and immediately ask for something to drink. Every five minutes they call a flight attendant(服务生)to ask if there are any problems with the plane. They also tell you about air accident. The best thing to do is to pretend to sleep.

       ④    

    These people are not necessarily very big. But they have a terrible habit of taking up all their room, and some of your room too. They usually sit with their arms and legs in your space.

    It was a summer afternoon in the countryside. Wan Bo, a university student, was painting while his classmate Tang Qi was making a wooden box by the river. A little riding on a rocking horse caught their eye by chance. It brought them back to their childhood, warm and happy.

    "Why not try to make one by ourselves?" said Wan Bo. "You are good at making things and I am interested in painting."

    "Actions speak louder than words," Tang Qi said. Then, the two young men began to collect some information about it. During those days, watching videos about caring(雕刻) and shaping wood into horse shapes on the Internet became an important part of their life.

    Several months later, a wooden rocking horse appeared. They felt so excited that they put the picture of it on the Internet right away. To their surprise, it attracted lots of people's attention and some even hoped to order one.

    The two young men thought it might be a good chance. They sent some forms to the customers to make a survey. According to the result, they made each customer a special rocking horse. These horses were quite different from those produced in other factories, and they soon became popular among the customers.

    In the first year of their new hobby, Wan and Tang made thirteen rocking horses. Sometimes, they also repaired rocking horses for people. They made the old ones look new again. Wan and Tang helped those people bring back many happy memories.

    Their hobby has now become a successful and busy business.

    Baozi is one of the common Chinese foods for breakfast. Who would have thought that this simple meal would become a leading character in a film, and even win an Oscar?

    On February 24, 2019, the short film Bao won the Oscar for Best Animated Short Film. In the film, a small baozi comes to life and becomes the "son" of a lonely Chinese woman in an immigrant(移民) family in Canada.

    Domee Shi, Pixar's first Chinese-canadian woman director, got the idea from her own experience. When Shi grew up, she was busy working and spent little time with her mother.

    Bao explores the life of an empty-nest Chinese Canadian mother who feels lonely after her son leaves home to go for his own life.

    In the film, many details show the way the Chinese woman loves her "son". She prepares delicious food, cleans up the house carefully and always buys him snacks. These details are true to the strong and protective love of Chinese parents for their children

    Traditionally, Chinese parents don't say 'I love you' to their kids. They express it with food or by fussing(小题大做) over them. "I didn't use dialogue in the film because I wanted it to be a story that spoke to everyone around the world." said Shi at an interview.

    Moreover, this film can serve as a bridge to help parents and children better understand each other and learn how to express love.
