Looking good can matter a lot when you are a teenager. Of course the budget(财政） matters a lot, too. Luckily, fashion trends (流行趋势) in the UK mean that getting the right image doesn't have to cost the earth. Here's a quick guide to which looks are hot this year.

    For girls, the 70s are back. Wide-legged jeans, platform shoes and skirts that reach the feet are again in fashion among UK teens, topped off with colored, shining eyeshadow. Girls can have fun mixing and matching bright shades. Colors like pink, orange and light yellow-green are all perfectly fit. Shorts and mini-skirts are still popular in cold weather. By wearing a pair of tights underneath ( 在..底下), girls can stay warm as well as fashionable in the winter.

    How about boys? To look lively, fans of skateboards and snowboards can dress in skinny jeans accompanied by a T-shirt topped off with a baseball cap or a woolen hat. Music is often an inspiration for fashion, and hip-hop music fans like to dress in baggy jeans, T-shirts, baseball caps and sneakers. For those who can afford it, designer clothing is a must, especially if the logo is showing.

    Science textbooks around the world have become suddenly out of date. Four new chemical elements(元素)have been added to the periodic table. A big decision now lies ahead-elements 113,115,117 and 118 need to be given their official names and symbols.

    New elements can be named after a mythical(神话的) concept, a mineral, a place or country, a property(性质) or a scientist. The names have to be unique and maintain “historical and chemical consistency”. This means a lot of “-iums”.

    “They're Latinising the name,” explains chemist Andrea Sella. “The most recent tradition is to name them after places or people.” The places chosen tend to be where the element was discovered or first produced.

    No one has yet named an element after themselves but many elements are named in honour of important scientists. Albert Einstein was given einsteinium. This can also be a way of righting the wrongs of the past. “Lise Meitner was really the chemist who spotted nuclear fission(核裂变)but she was never really recognised for it because she was Jewish and a woman, ” says Sella. “Giving an element a name that reminds us of her is greatly important. ”

    The naming process isn't quick. The scientists who discovered them will start things off by suggesting a name. But it will be down to the International Union of Pure and Applied Chemistry (IUPAC) to approve it. A special division of the US-based group has to accept the suggestion. Then there is a public review period of five months before the IUPAC gets the final approval. Once it's ready, the name is announced in the scientific journal Pure and Applied Chemistry.

    Naming an element is not just about functionality. Names are always important.

    When I was going home to India last year, I called up my mother to ask if she wanted anything from China.

    When India had not opened up its markets to the world, I carried suitcase loads of dark glasses and jeans. Thankfully, we can get all these anywhere in India now.

    Still, her answer surprised me, “Green tea.”

    As long as I can remember she didn't even drink Indian tea.

    I dutifully bought a big packet of Longjing and headed home to hear the story. My mother and her brother, both regular newspaper readers, believed that Chinese green tea was the wonder drug for all illnesses.

    At the turn of the century，China was not really familiar to the average Indians. It was a strange country.

    How things change! And how soon!

    Now every town of any size seems to have a “China Market”. And everyone is talking about China.

    The government of India has planned to send a team to China to see how things are done. A minister once said that India must open the doors for more foreign investments(投资) and such a step would “work wonders as it did for China”．

    But it's a two way street. I just heard about a thousand Shenzhen office workers who have gone to Bangalore to train in software. Meanwhile, all the Indian IT majors are setting up a strong presence in China.

    No wonder that trade, which was only in the millions just ten years ago，was expected to hit about $15 billion for last year and $20 billion by 2008, a goal set by both governments.

    No wonder，my colleague wrote some weeks ago about this being the Sino－Indian(中印) century as the two countries started on January 1 the Sino－Indian Friendship Year.

    But what is still a wonder to me is my mother drinking Chinese tea.

    The editor of the new Cool Camping Britain guide 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 The Lord of the Rings author's fantasy landscapes. The campsite itself is as wild and wonderful as its setting.

    Open April - September, 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 but get into nature. You can put up your tent in the bottom field or the woodland beyond.

    Open Easter - October, from ￡10 per tent per night.

    Pleasant Streams Farm, near St Austell, Cornwall

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

    Open Easter - September, from ￡10 per tent per night.

    Troy town Campsite, St Agnes, Isles of Sciily

    Its only campsite, Troy town, couldn't be in a more remote position. Isolation is its greatest advantage — 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 March - October, from ￡7. 50 per tent per night,

    Skeptics are a strange lot. Some of them refuse to admit the serious threat of human activities to the environment, and they are tired of people who disagree with them. Those people, say skeptics, spread nothing but bad news about the environment. The “eco-guilt” brought on by the discouraging news about our planet gives rise to the popularity of skeptics as people search for more comforting worldviews.

    Perhaps that explains why a new book by Bjorn Lomborg received so much popularity. That book, The Skeptic Environmentalist, declares that it measures the “real state of the world” as fine. Of course, another explanation is the deep pockets of some big businesses with special interests. Indeed, Mr. Lomborg's views are similar to those of some Industry-funded organizations, which start huge activities through the media to confuse the public about issues like global warming.

    So it was strange to see Mr. Lomborg's book go largely unchallenged in the media though his beliefs were contrary to most scientific opinions. One national newspaper in Canada ran a number of articles and reviews full of words of praise, even with the conclusion that “After Lomborg, the environmental movement will begin to die down.”

    Such one-sided views should have immediately been challenged. But only a different review appeared in Nature, a respected science magazine with specific readership. The review remarked that Mr. Lomborg's “preference for unexamined materials is incredible(不可信的)”.

    A critical (批判的)eye is valuable, and the media should present information in such a way that could allow people to make informed decisions. Unfortunately, that is often inaccessible as blocked by the desire to be shocking or to defend some special interests. People might become half-blinded before a world partially exhibited by the media. That's a shame, because matters concerning the health of the planet are far too important to be treated lightly.

    What's the one thing every child wants in school? More breaks! And that is exactly what some schools are giving students, which turns out to be beneficial for everyone. Eagle Mountain Elementary School in Fort Worth, Texas, is one of four public schools carrying out the LiiNK program, a project that increases breaks per day to improve creativity, develop character, and heighten school success.

    LiiNK was inspired by Scandinavian approaches to learning based on the simple concept （观念）of giving children more outside playtime and less time spent indoors. In Finland, where the system has been in place for decades, students have some of the highest scores on global assessment tests. Instead of spending increasing amounts of time inside the classroom, they're putting more and more focus on physical activity. Finnish kids get to enjoy 15 minutes of playtime for every hour of class.

    After spending six weeks in Finland in 2016, Debbie Rhea, the creator of LiiNK and professor at Texas Christian University, discovered that the additional breaks of "outdoor play" actually helped students improve their performance inside the classroom. "You start putting 15 minutes into these kids every so often and it gives the platform for them to be able to function at their best level," she says.

    Other studies have shown that outdoor playtime decreases restlessness, anxiety, and has a whole other benefits such as improved motor skills, physical fitness, and social development. Rhea started carrying out the program in private schools in 2017, and has since expanded her program to districts in Texas, Oklahoma, Minnesota, and Utah and the children in these schools are all the happier for it. It just goes to show that the best way to raise happy and successful children, is to simply let them be kids every once in a while.
