The hottest TV drama in China – “Nirvanain Fire” or “Langya Bang” has just ended. Millions of people waited every day after midnight for the latest (two) episodes. Are you one of them? What is the story about? Why the show is so popular?

  “Nirvana in Fire” is based on an Internet novel by author HaiYan, who was invited to pen the screenplay for the television adaptation. The 55-episode series, set in a fictionalized kingdom, weaves together two storylines — one about a betrayed general's revenge and the other about princes fighting for the throne.

    The series was put on screen on Sep. 19th, and the number of Internet views exceeded 140 million times the next day. Only during the week of National holiday, the number increased by 1.6 billion.

    It's now the hottest Chinese TV show with a very high score of 9.3 on Douban. (The classical TV drama, Journey to the West, produced in 1986 is with the same score). Previous and recent costume dramas such as “The Journey of Flower” and “Yun Zhong Ge” only scored 6.4 and 3.5.

    Drawing comparisons to “The Count of Monte Cristo”, the story revolves around a gifted young man named Lin Shu, whose father serves as a general. Already a high-ranking military officer by his teenager years, Lin Shuenjoyed a close friendship with Prince Xiao Jingyan and was even engaged to Princess Nihuang.

   At age 17, however, Lin Shu's life turned upside down when his father's army was framed and destroyed by a foxy political rival. LinShu escaped death, but due to the poisoning, his body became weak and frail, and he lost his martial arts abilities. From then on, his face was pale and his fingers always ice-cold.

    After twelve years, Lin Shu returned to his country's capitalwith a new name, Mei Changsu, and a new identity, the leader of the Jiang ZuoAlliance. He then became the strategic adviser for his friend, Prince Jingyan, who had been exiled(流放) by the king. Despite the efforts of Prince Xiao Jingheng and the crown prince to win the throne for themselves, Mei Changsu succeeds in paving the road for his friend to take over as king, as well as the avenging the injustices dealt to histroops many years before.

    The oddness of life in space never quite goes away. Here are some examples.

    First consider something as simple as sleep. Its position presents its own challenges. The main question is whether you want your arms inside or outside the sleeping bag. If you leave your arms out, they float free in zero gravity, often giving a sleeping astronaut the look of a funny balled （芭蕾）dancer. “I'm an inside guy,” Mike Hopkins says, who returned from a six-month tour on the International Space Station. “I like to be wrapped up.”

    On the station, the ordinary becomes strange. The exercise bike for the American astronauts has no handlebars. It also has no seat. With no gravity, it's just as easy to pedal violently. You can watch a movie while you pedal by floating a microcomputer anywhere you want. But station residents have to be careful about staying in one place too long. Without gravity to help circulate air, the carbon dioxide you exhale (呼气) has a tendency to form an invisible （隐形的）cloud around you head. You can end up with what astronauts call a carbon-dioxide headache.

    Leroy Chiao, 54, an American retired astronaut after four flights, describes what happens even before you float out of your seat,”Your inner ear thinks your're falling . Meanwhile your eyes are telling you you're standing straight. That can be annoying—that's why some people feel sick.” Within a couple days —truly terrible days for some —astronauts' brains learn to ignore the panicky signals from the inner ear, and space sickness disappears.

    Space travel can be so delightful but at the same time invisibly dangerous. For instance, astronauts lose bone mass. That's why exercise is considered so vital that National Aeronautics and Space Administration (NASA) puts it right on the workday schedule. The focus on fitness is as much about science and the future as it is about keeping any individual astronauts return home, and, more importantly, how to maintain strength and fitness for the two and a half years or more that it would take to make a round-trip to Mars.

    Friendship Day is celebrated every year on the first Sunday in the month of August. People give their loved ones or friends friendship bracelets (手镯) and other gifts to celebrate their friendship. The culture of friendship bracelets is as old as even thousands of years.

    After the World War II, the paracord (伞绳) bracelets became very popular. These were also known as survival bracelets. One of the main reasons is that it was often used for a rescue purpose. Paracord, used in the parachute, does not wear away easily and is strong and durable. Because of its light weight, people could carry it along easily. If required, it could be made a very long rope and be used as a rescue rope. Hunters used it to find their way that they could return without getting lost.

    Today there are all kinds of paracord bracelets, made of coloured strings. Girls like thinner and colourful bracelets. Many choose to make the bracelets by themselves for their dear friends. This not only appeals more to the feelings of people but also makes them know how much their friends mean to them. People keep the bracelets given by their friends long. Many people choose coloured strings keeping the depth of their friendship in mind. White, yellow, orange and red show the different levels of friendship. Pure friendship is shown in white; the red colour means love. An orange friendship bracelet is given to show strong friendship and yellow as simple friendship. Today, not only do the young people show these friendship bracelets, but even the old do.

    Does friendship have an age? Yes. Friendship is like the wine, and the older you get, the older and stronger your friendship is.

    TED is a non-profit organization devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, and Design. Since then it has stepped into more and more fields. It includes two annual ( 年度的) conferences-the TED Conference on the North American West Coast each spring, and the TED Global Conference in Edinburgh UK each summer, which bring together the world's most excellent thinkers and doers, who are challenged to give the talk of their lives ( in 18 minutes or less).

    On ted.com, we make the best talks and performances from TED and partners available to the world, for free. More than 1, 200 TED talks are now available,' with more added each week, which cover almost all topics from science to business to global issues- in more than 110 languages. They really help share ideas in communities around the world.

    We believe in the power of ideas to change attitudes, lives and eventually, the world. So we' re building here a clearinghouse (信息交流中心 ) that offers free knowledge and inspiration from the world's most inspired thinkers, and also a community of curious souls to engage with ideas and each other. Have an idea? We want to hear from you.

    Today, TED is best thought of as a global community. It's a community welcoming people from every field and culture who seek a deeper understanding of the world.

    The introduction of the iPad, with its touch screen technology, has allowed even very young children to take advantage of a computer. So what if all children in a school were given an iPad to use in class and take home with them?

    Anne Laure Bazin works in a school where every child, teacher and teaching assistant is given a free iPad to use in and out of lessons. For her, the main advantage of everyone having an iPad had been the improvement in communication. Documents can be emailed straight over to workmates during a meeting. Children submit their homework by email, or through the school's learning environment. Teachers now take the register (点名) using their iPad, which means that there is a record of which children are in school, and which classroom they are in.

    The use of iPad has encouraged greater sharing of resources among teacher. All communication with parents is now done by email. Working as a group in class is much easier as children can share documents. The whole class can look at one child's work by attaching (连接) the iPad to the whiteboard. If a child has forgotten the textbook, the teacher can take a photograph of the relevant (相关的) page and send it to the student in class.

    While the use of the iPad in schools has revolutionized (变革) the way children are taught, it hasn't completely replaced more traditional methods of teaching. Worksheets are still used in class as some children prefer the contact with paper. The children all have a textbook and exercise books. In Anne Laure's school, parents feared that the iPads would replace exercise books and children would lose handwriting skills. Anne Laure says, "The teacher are not ready to let go of the traditional style of teaching. We have welcomed the iPads in so much as they help communication and widen the resources available but we are not ready to let go of paper yet. The children themselves still value their exercise books and depend on them for review."

What will you do if you can't eat everything bought in the canteen(食堂)? {#blank#}1{#/blank#} According to a survey, what students waste every year could feed over 10 million people. 

{#blank#}2{#/blank#} According to Xinhua News Agency, the food wasted by Chinese people is about 50 million tons of grain every year, which could feed 200 million people. 

Food waste, which has become a global issue, serves as a mirror that reflects various cultural and social issues in different countries. In the west, for instance, consumerism, the belief that it's good to use a lot of goods and services, is often to blame for food waste. {#blank#}3{#/blank#}Chinese people are well known for being hospitable and generous. Many even feel that they lose face if their guests have eaten all the food. On campus, a generation of single children is less aware of the food waste issue. Students nowadays are well protected by their families and hardly have any concept of how much toil (辛劳) others go through in order to provide them with the food they eat. 

{#blank#}4{#/blank#}There are 925 million hungry people in the world. They don't have enough food to eat. And farmers work very hard to grow the crops. {#blank#}5{#/blank#}It's also important that everyone thinks about how they can do their bit to reduce food waste. Recently a campaign against food waste launched on line in China might make you think twice about being so wasteful.
