Avatar has become the most successful movie in 2009. It is about a soldier whose mind is set into the body of a giant blue alien. He was sent to a dangerous planet called Pandora. His mission（使命） is to find a rare mineral（矿物质）. The mineral is the key to solve the earth's energy crisis(危机).

    According to the latest figures（数字）, Avatar has become the fastest film ever to make more than 1 billion dollars in ticket sales around the world. When it had been shown in cinemas for several days, it became the most popular film ever made.

    Avatar knocked the movie Titanic off the international release top spot. But Titanic's director James Cameron probably won't be too upset, because Avatar is directed by him as well! Before Avatar was filmed, the best selling film ever was Titanic.

    James Cameron decided to make Avatar in 1999. However, the means（方法）to realize his vision（影像画面） did not exist yet. In 2002, The Lord of the' Rings: The Two Towers made him believe that CGI (电脑影像合成) effects had progressed enough to make this film. After several years of production, the 3D spectacular Avatar successfully showed us a fully immersive experience.

    LONDON-A British judge on Thursday sentenced a businessman who sold fake(假冒的) bomb detectors（探测器） to 10 years in prison, saying the man hadn't cared about potentially deadly consequences.

    It is believed that James McCormick got about $77.8 million from the sales of his detectors-which were based on a kind of golf ball finder--to countries including Iraq, Belgium and Saudi Arabia.

    McCormick, 57, was convicted(判罪) of cheats last month and sentenced Thursday at the Old Bailey court in London.

    “Your cheating conduct in selling a great amount of useless equipment simply for huge profit promoted a false sense of security and in all probability materially contributed to causing death and injury to innocent people,” Judge Richard Hone told McCormick. “you have neither regret, nor shame, nor any sense of guilt.”

    The detectors, sold for up to $42,000 each, were said to be able to find such dangerous objects as bombs under water and from the air. But in fact they “lacked any grounding in science” and were of no use.

    McCormick had told the court that he sold his detectors to the police in Kenya, the prison service in Hong Kong, the army in Egypt and the border control in Thailand.

    “I never had any bad results from customers,” he said

    Sunstroke (中暑) is a condition that can quickly go from dangerous to deadly, especially if proper care isn't given immediately.

    Sunstroke, sometimes called heatstroke, is a result of the body temperature rising above safe limits. This causes the body's necessary functions to stop working.

    It's usually pretty easy to avoid sunstroke, as long as proper action is taken. In that case, you need to act as quickly as possible to return that person's body to a safe temperature. Here are a few tips to help treat sunstroke.

Call for help

    Call to get an ambulance as quickly as possible. This should be the first thing you do, especially if the sunstroke person has fainted(昏倒). Also, call for help from anyone nearby if you're in a public place. If there's no one around, call someone nearby if they can get there sooner than an ambulance. Ask everyone to bring you as much water as possible, if there isn't much nearby.

Get the person to a cooler area

    If there's a building nearby, aim for that. Anywhere with plenty of air conditionings and water is perfect. If a building isn't available, bring the person to a well shaded area.

Get the water flowing

    If the person is still conscious, get him or her to drink water. If there's a bathtub available，fill it with cool water and put the person in it.

If your water supply is limited, you have to save it. Dampen a towel or shirt and put it on the person's body. Focus on the face, neck，and chest.

Fan the person

    Getting moving air over the person cools him or her down. Use anything, a towel or sheet, a shirt your hands，or a piece of board. This is where having many people around really helps, as they can combine to fan the entire body.

    Nations in the UN have agreed that the world needs to completely stop plastic waste from entering the oceans. The UN resolution(决议) has no timetable. But ministers at an environment summit believe it will set the course for much tougher policies and send a clear signal to business.

    Under the resolution, governments would establish an international task force(特遣小组) to advise on fighting what the UN's oceans chief has described as a world crisis. One controversial issue is the wish to include businesses on the global task force. Ministers say the problem will not be solved without business, but green groups point out that some firms in the plastics industry have been against restrictions for decades. Vidar Helgesen, a leading voice in the talks, told BBC News, “Business is listening to markets and seeing how marine litter(海洋垃圾) is a growing popular concern. It's possibly the fastest－growing environmental problem and it's therefore a fast－growing problem for business. We need to bring on board those companies that want to change things, and then look at taxes and regulations to make more companies act.”

    Certainly, there has been resistance from plastics firms to the bans. One UN delegate, who did not want to be named, stated that journalists in some countries were being paid by the plastics industry to write stories about job losses following the plastic bag ban. But they did not mention the jobs being created in alternatives, such as labour－intensive basketwork, which provides work for the rural poor. But some governments are standing firm, and the meeting has witnessed individual nations declaring tougher action against single－use plastic bags.

    The UN's spokesman Sam Barratt told BBC News, “Of course we would have liked to have gone further, but this meeting's made real progress. There's now a sense of urgency and energy behind the issue that we haven't quite seen before. What is obvious, though, is that the UN can't solve this problem on its own. We need to do it in partnership with governments, businesses and even individuals.”

    Ancient Chinese folk paintings and many other art styles have been passed down from generation to generation, and are still practised in different parts of China. Here's a look at four unique Chinese folk art forms.

    Chinese Opera (戏剧) is the traditional form of Chinese drama. According to incomplete statistics, in China's various ethnic regions there are about more than 360 kinds of operas. The most famous ones include Peking Opera, Kunqu Opera, Yueju Opera, Yuju Opera, Sichuan Opera, Fujian Opera, Hebei opera, Huangmei Opera arid so on, in total more than 50, among which Peking Opera is the most popular in China.

    Shadow Play (皮影戏) dates back to Western Han Dynasty in Shaanxi more than 1,000 years ago. The moving figures, usually carved out from leather, are operated by folk artists, accompanied by music and singing. It is the world's first dubbed (配音的) motion picture art form, thus considered the "ancestor" of modern film. Today this art form is still popular in northern China.

    Paper-cutting (剪纸) is one of the most popular traditional decorative arts in China with a long history. Paper-cutting can be seen across China and it has even developed into different local genres (流派). They are usually used to decorate gates and windows during festivals.

    The Kite was invented by Chinese people. According to legend the earliest kite in China was a wooden bird by Mo Di in the Eastern Zhou Dynasty. Later his student Lu Ban improved the tech and used bamboo as material to make a kite. Today, various kite-flying activities can be found in different regions of China. Shandong Weifang Kite Festival is held every year and attracts lots of kite lovers and travelers.

    Reading books and looking at pictures is great, but nothing facilitates (促进) learning like travel, especially for teenagers. Not only do they get to see a world beyond their neighborhood, they also get to experience it, feel it, taste it, hear it and better understand the world around them.

    After nearly four decades in the classroom and traveling the world, Phyllis Duvall Bailey knew this perhaps better than anyone else.

    Becoming involved in the work in AKA Sorority Inc in US, she worked to educate children about the United Nations. There was no doubt in Bailey's mind that the lessons would mean so much more if the students could see things for themselves.

    Starting in 2015, Bailey, 82, set out to take her students to the UN Headquarters in New York City to give them a "Window Seat to the World", and thus transformed them into global citizens.

    Indeed, it is a great opportunity to give students national and international exposure. Since Bailey saw the students as future leaders, she was desperate to expose them to the UN, its mission, its agendas (议程) and its supporting organizations.

    She decided to give $10, 000 of her own money to pay for the late June trip, enough to take 10 students aged 14-17 on a four-night stay in New York. There, they had guided tours of the UN Headquarters and the New York City Harbor (海港).

    It was Quenyaun Payne's first trip to the city and Taylor Sappington's second. Payne, 17, is a senior at Mceachem High School in the state of Georgia, US. Sappington, 15, is a junior at Therrell High School in Atlanta, Georgia, US. Both said their visit to the UN was inspiring.

    "I like not only how countries are working together but they're focused on common goals like global warming and keeping peace," Sappington said.

Payne commented, "The trip was amazing. I'm so thankful Mrs. Bailey made it possible."

    Actually, there are a lot of people grateful for the retired teacher's effort. The United Nations Association of Atlanta recently gave Bailey its Humanitarian Award, and the United Nations Association of the US-awarded her with the National Education Award.

    But Bailey wasn't looking for recognition or even gratitude. Over those four days in New York, she'd already felt it and seen it in the eyes of those 10 teenagers, Payne and Sappington included, who made the trip.

    "It has been a real joy to get to see and watch their reaction to new experiences," she said.
