In most parts of the world, many students help their schools make less pollution. They join environment club. In an environment club, people work together to make our environment clean.

    Here are some things students often do.

    No-garbage lunches. How many lunch bags do you throw away after lunch? Environment clubs ask students to bring their lunches in bags that can be used again. Every week they will choose the classa that make the least garbage and report them to the whole school.

    No-car day. On a no-car day, nobody comes to school in a car including the students and the teachers. Cars give pollution to us, so remember:

    Walk, jump, bike, or run!

    Use your legs! It's lots of fun!

    Turn off the water! Do you know that some toilets can waste twenty to forty cubic（立方米）of water an hour? In a year, that would fill in a small river. In the environment clubs, students mend（修理）those broken toilets.

    We love our environment. Let's work together to make it better.

    Have you ever seen the movie. Big Hero 6 ? Baymax(大白) is a main character in the movie. He's a friendly big robot that looks after people's health. If there is a robot like Baymax in our real life， people will get more benefits. The robot will be especially helpful in caring for the old. The health of old people needs greater monitoring and care.

    Scientists in America are now working to make Baymax a really(实现)- Actually. They have already produced some health care robots. These robots provide brain video games to improve people's memory. The garner can help the old remember things for longer. Besides， these  provide special app (应用程序） to help the old manage their health at home. The apps can check  the old people' heart rate (心率) and tell them to take their medicine on lime. The apps can also record their daily activities. Such collected information helps doctors discover the cause of an illness faster and more correctly. But the health care robots are't as clever as Baymax yet.

    Nowadays，scientists are working on improving the health care robots. They pope the robots can produce electricity by walking across the floor. If they succeed. batteries will not be needed. They also hope the robots communicate with humans in the daily life so to make people happier and healthier.

    Scientists are trying to realize these dreams. Like Baymax， these health care robots may save people's lives in the future. We are looking forward to them.

    Hiccup is a young Viking. Toothless is a dragon and he can give off fire with his mouth. They go through many ups and downs together in the How to Train Your Dragon(《驯龙高手》) movie series. Now they are back with a new film!

    In the last movie, they had to protect their home. Humans and dragons lived together happily there. But now, there are too many dragons. A man tries to kill them. He burns down parts of their home. Hiccup and Toothless have to look for a new world for dragons to live in. Will they find it? Find out by watching How to Train Your Dragon: the Hidden World.

    Dragon acts

    The How to Train Your Dragon movies are from the book series of the same name British writer Cressida Cowell wrote the 12—book series. They came out from 2003 to 2015.

    How to Train Your Dragon the Hidden World is the last movie in the series. It opened in Chinese mainland theaters on March 1. Toothless get his name because he has retractable(伸缩自如的)teeth.

    Almost every Chinese can recite the famous poem, "Every grain on the plate comes from hard work(谁知盘中餐, 粒粒皆辛苦)."But sadly, many of us don't actually get the real meaning of these lines：Don't waste food.

    A CCTV programme, News One Plus One, reported that the food Chinese people throw away every year is enough to feed 200 million people for a year.

    Do we have too much food? No, according to the UN World Food Programme, there were 925 million hungry people around the world in 2010, especially in developing countries.6 million children die of hunger every year.

    Chinese people are well-known for being generous. Many even feel that they will lose face if their guests have eaten all the food on the table.

    Luckily, a number of people have realized the importance of saving food. In November, 2011, Li Hong, a waitress in a restaurant in Nanjing, became famous because she took some leftover(剩余的)food home for her son. Many people stood by her side and agreed that it was not right to waste food.

    What should we do in our daily lives to save food? Here are some tips：

    Do not order too much in a restaurant. Only order what you want to eat. If you cannot eat all the food you ordered, take the rest of it home.

    Don't be too picky(挑剔的)about food. Some food may not taste great, but your body needs it.

    Keep an eye on what food you have at home. Don't buy too much, especially vegetables and fruit.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel(化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles(EVs，电动车). Among them, China is' taking a leading role and has created the world's largest EV market.

    Last year, over 40 percent of the 753, 000 EVs sold in the world were sold in China, more than twice as large as the number sold in the United States.

    "Filling up a fossil fuel car with gas is more expensive than charging an electric car," said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles and the cars can't go far before needing to be recharged.

    Some of these problems are being solved. In 2014, China had 31, 000 charging piles. Now China has the world's largest EV charging network, with more than 167，000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions by 2030.

    "As China goes, so will the world's car industry," the Wall Street Journal said. China has taken a leading role in the world's electric vehicle industry.
