More and more comment(评论) sections are being shut down online.

    Autumn Phillips had had enough. On August 19, the executive editor of the Quad-City Times in Iowa, and Illinois, US visited her website, qutimes. com, and saw a story about a man who had been shot to death. When she got to the readers' comments section at the end, she was shocked by what she saw. Below the story was a growing string of comments—a racist remark about democratic( 民主的) voters, a negative comment about police...So Phillips decided to do something she had been thinking about for a long time: she shut down the comment section.

    Phillips was not alone in making such a move. Last week, NPR announced it too was closing its online comments section. The decisions don't mean that the news outlets are no longer interested in what their audiences are thinking. Both stressed their eagerness to hear from readers and listeners on social networks. But both agreed that comments had deviated from their original intention. And so they had.

    In the early days of digital journalism, comments were seen as a key part of the new media, a wonderful opportunity for strengthening the dialogue between news producers and their audiences. It was a welcome change, given that for long many news organizations were far too separated from their readers. Much more back and forth conversation seemed like healthy and welcome evolutions. Sadly, that's not the way things turned out. Rather than a place for exchanging ideas, comments sections became the home of ugly name-calling, racism and anti-women language. Besides their poisonous quality, comments seem out of place today.

    “Since we made the announcement, I've received an outpouring of responses from our readers,”she says. “I've heard from parents whose children were hurt by our online comments. I've heard from people who said they wouldn't send in letters to the editor because they were attacked so fiercely by comments, and it wasn't worth it.”

    Businesses are witnessing a difficult time, which has in turn produced influence on consumers, desire to go green. However, shoppers are still laying stress on environmental concerns.

    Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy.

    This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more environmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies, with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company's environmental reputation was not good enough.

Harry Morrison, chief executive (主管) of the Carbon Trust, sympathizes: "I understand this situation where survival is very important now. But from environmental considerations, the clock is ticking—we don't have much time. In addition, cutting carbon has an immediate effect as costs drop and a medium-term benefit for the brand."

    Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses to buy carbon allowances to make up for their emissions (排放). Those that have taken early action will have a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.

The Carbon Trust believes that it can help by informing customers about the good work companies are doing. "When companies are granted (授予) the standard, they can use a logo (标识) in all their marketing which makes it clear that they are working towards cutting emissions," Mr. Morrison said.

    Researchers say they have created a new super-tough material in the laboratory. It is stronger, lighter and costs less than steel. But the new material is not a product of high technology. It is wood. Researcher Liangbing Hu says that it can compete with some of the world's strongest materials or even replace steel.

    The product is called Super Wood. It doesn't require any special raw, unprocessed material. That means the cost of the product will be relatively low.Hu said, “We can start with very cheap wood, and also very fancy, expensive wood. But in the end, we get very similar performance.”

    Super Wood is made by partially removing a natural polymer called lignin（木质素）. Hu explained, “Lignin is like glue to hold all the parts together in natural wood. To be able to densify（增密）the wood completely, some of the lignin has to be removed. “Strong chemicals are put on the wood to remove about half of its lignin. Then, after being left in extreme heat and pressurized for a day, the treated wood is ready.

    The wood is strong enough to build automobiles, airplanes, wind turbines and more. Researchers are finding many new ways to use wood, including creating batteries and see-through wood and paper.Hu said, “Wood has been existing on Earth for more than a million years. And human beings have been using wood for furniture, construction for more than 10 thousand years. And the more we worked on this material, we realized, we have never fully exhausted the potential of this amazing material.”

    Britain and France are two important countries in Europe. They are neighbors, separated only by the 20-mile seaway of the English Channel. And for most of the time that the two countries have existed, the French and the British have been rivals or even enemies. One conflict between the two countries lasted over 100 years, and the British and French were at war through the 18th century.

    There is no fighting now, of course. But there is still a strong sense of rivalry (敌对) between the two nations. That's why a recent survey in the UK caused a major shock.

It revealed (揭露) that one third of the British people would like to live in France. It also showed that twenty-one percent of British people would actually prefer to have been born in France.

    Many reasons were given. France has a better climate and a more relaxed lifestyle, with some of the longest holidays in Europe. It is thought to have better public services in every area from health to transport. People in France work shorter hours and enjoy longer vacations. And think of the food and wine!

    Estimates (估计) of the numbers of Britons living in France range from 100,000 to half a million. But it is not one-way traffic. Around 15,000 French people per year come to live in Britain, mainly settling in London. They are attracted by higher pay in Britain, lower taxes, a more dynamic lifestyle. Now it seems that people can go to the place that suits them best.

    Sometimes people add to what they say even when they don't talk. Gestures are the "silent language" of every culture. We point a finger or move another part of the body to show what we want to say. It is important to know the body language of every country or we may be misunderstood.

    In the USA, people greet each other with a handshake in a formal introduction. The handshake must be firm. If the handshake is weak, it is a sign of weakness or unfriendliness. Friends may place a hand on the other's arm or shoulder. Some people, usually women, greet a friend with a hug.

    Space is important to Americans. When two people talk to each other, they usually stand about two and a half feet away and at an angle (角度), so they are not facing each other directly. Americans get uncomfortable when a person stands too close. They will move back to have their space. If Americans touch another person by accident, they say, "Pardon me" or "Excuse me". Americans like to look at the other person in the eyes when they are talking. If you don't do so, it means you are bored, hiding something, or are not interested. But when you stare at someone, it is not polite.

    For Americans, thumbs-up means yes, very good, or well done. Thumbs-down means the opposite. To call a waiter, raise one hand to head level or above. To show you want the check, make a movement with your hands as if you are signing a piece of paper. It is all right to point at things but not at people with the hand and index finger (食指). Americans shake their index finger at children when they scold them and pat them on the head when they admire them.

    Learning a culture's body language is sometimes confusing. If you don't know what to do, the safest thing to do is to smile.

The editor of the Cool Camping Britain chooses some of his favorite new finds in England, Wales and Scotland.

Cleadale, Isle of Eigg, Inner Hebrides

Is this Britain's most beautiful campsite? From the grassy point looking seaward to the mountains, it's not hard for campers to see how the island inspired fantasy landscapes in The Lord of the Rings.The campsite itself is as wild and wonderful as its setting.

Open April~September, pitches from £5 per tent per night.

Swattesfield, Thornham Magna, Suffolk

Deep in the wilds of north Suffolk, this seven-acre campsite has only been open for a few years, with two fields separated by a lake and surrounded by woodland. The position is perfect. It's a great place to do nothing and get into nature.You can set up your tent in the bottom field or the woodland beyond.

Open Easter~October, pitches from £10 per tent per night.

Pleasant Streams, near St Austell, Cornwall

This site, by a lake, is all about simple pleasures. Located in the former mining village, it has a summerhouse with books and games for a rainy day, many animals including pigs, hens, goats and ducks, and a pub just a 10-minute stroll (walk) away. There's very little to do here, no bells or whistles. Campfires are encouraged.

Open Easter~September, pitches from £10 per tent per night.

Troytown Campsite, St Agnes, Isles of Scilly

Its only campsite couldn't be in a more remote position. Isolation is its greatest asst (优点)－so bring plenty of books to read and don't expect a phone signal. But at least one of life's necessities is available. Lying on the hillside overlooking the bay and near the island of the Gugh, it might just win the prize for best beer garden view in England.

Open MarchOctober, pitches from 7.50 per tent per night.
