1 . A recent study suggests that vitamin D pills can help speed up the time taken for burns to heal, and prevent scarring(结疤). The vitamin, which is produced naturally in the body when the skin is exposed to sunshine, is believed to help protect against burning.
Previous studies have shown that vitamin D pills help decrease redness and swelling after sunburn, and may be one of the reasons why the body produces the chemical.
The research from Birmingham University, has found they may also help relieve other types of burn. Researchers monitored 38 patients who had suffered serious burns for a year and recorded their levels of vitamin D. They found that those with the highest levels of vitamin D had better wound healing and fewer scars.
Professor Janet Lord said: “Low vitamin D levels were associated with worse results in burn patients including life-threatening infections(感染),death and delayed wound healing. Major burn injury severely reduces vitamin D levels and adding this vitamin back may be a simple, safe and cost-effective way to improve the condition for burn patients.” Professor Lord and her team are now focusing on finding out why there is a rapid loss of vitamin D in patients immediately following burn injury and hope that they may be able to prevent this in future.
The amount of reduction in patients’ vitamin D levels was not related to the severity(严重程度) of the burn, so levels may also be decreased in minor burn injury, suggesting taking vitamin D pills could also help people with everyday burns. Public Health England now recommends that all Britons take vitamin D pills in the winter because it is impossible to make sufficient quantities in the darker months.

2 . My challenge for you is this： to read a book for 15minutes every single day for a month.
Let me explain a bit, by telling you where the challenge came from. I have many things in common with my dad, like music taste and sense of humor, but sadly reading isn't one of them. I can happily spend a whole day with a book, but my dad can't read a book for longer than about 5 minutes. He reads emails, websites and papers for work, but not books. He's busy, so I think sitting down to read for just 15minutes a day is a good way to relax and to introduce him to reading.
My dad is not the only person who avoids books. I know lots of people would rather relax on their computers or in front of the TV. Everyone is different and has their own interests, but I think there are lots of benefits to reading, which screen﹣based activities don't have.
Firstly, it's better for your eyes. Looking at screens can be very stressful for your eye muscles, and clearly you should avoid looking at screens for an hour before bed, to get a good night's sleep．
One thing I personally love reading, is being transported to another world﹣I often forget the time or things around me! Reading is a great way to switch off before you go to bed, because you think more about the world of the book, rather than the real world, so you can truly relax. I know you can be transported to a different world in a film or a TV show, but I think books do it better．
I also enjoy hearing what people are doing and finding out what they think. Reading gives me the chance to get to know hundreds of new people! It also teaches you to see things from other people's point of view, and understand other people's decisions or opinions. With a book, you can hear everything a character is thinking or feeling﹣you really can be inside someone else's head!
So give it a go! Take 15 minutes when you are waking up, going to bed, eating lunch, or having a coffee. If you read a lot, why not try 15 minutes of an English book, or pass the challenge on to someone else? Good luck, and happy reading!

3 . Some of the world’s most famous musicians recently gathered in Paris and New Orleans to celebrate the first annual International Jazz Day. UNESCO( United Nations Educational, Scientific and Cultural Organization) recently set April 30 as a day to raise awareness of jazz music, its significance, and its potential as a unifying(联合) voice across cultures.
Despite the celebrations, though, in the U.S. the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations.
It’s Jason Moran’s job to help change that. As the Kennedy Center’s artistic adviser for jazz, Moran hopes to widen the audience for jazz, make the music more accessible, and preserve its history and culture.
“Jazz seems like it’s not really a part of the American appetite,” Moran tells National Public Radio’s reporter Neal Conan. “What I’m hoping to accomplish is that my generation and younger start to reconsider and understand that jazz is not black and write anymore. It’s actually color, and it’s actually digital.”
Moran says one of the problems with jazz today is that the entertainment aspect of the music has been lost. “The music can’t be presented today the way it was in 1908 or 1958. It has to continue to move, because the way the world works is not the same,” says Moran.
Last year, Moran worked on a project that arranged Fats Waller’s music for a dance party, “Just to kind of put it back in the mind that Waller is dance music as much as it is concert music,” says Moran. “For me, it’s the recontextualization. In music, where does the emotion(情感) lie? Are we, as humans, gaining any insight(感悟) on how to talk about ourselves and how something as abstract as a Charlie Parker record gets us into a dialogue about our emotions and our thoughts? Sometimes we lose sight that the music has a wider context,” says Moran, “so I want to continue those dialogues. Those are the things I want to foster.”

4 . In the depths of the French Guianese rainforest, there still remain unusual groups of indigenous(土著的) people. Surprisingly, these people live largely by their own laws and their own social customs. And yet, people in this area are in fact French citizens because it has been a colony of the French Republic since 1946. In theory, they should live by the French law. However, their remote locations mean that the French law is often ignored or unknown, thus making them into an interesting area of “lawlessness” in the world.
The lives of these people have finally been recorded thanks to the effects of a Frenchman from Paris called Gin. Gin spent five months in early 2015 exploring the most remote corners of this area, which sits on the edge of the Amazon rainforest, with half its population of only 250,000 living in its capital, Cayenne.
“I have a special love for the French Guianese people. I have worked there on and off for almost ten years,” says Gin. “I’ve been able to keep firm friendships with them. Thus I have been allowed to gain access to their living environment. I don’t see it as a lawless land. But rather I see it as an area of freedom.”
“I wanted to show the audience a photographic record touching upon the uncivilized life,” continues Gin. “I prefer to work in black and white, which allows me to show different specific worlds more clearly.”
His black-and-white pictures present a world almost lost in time. These pictures show people seemingly pushed into a world that they were unprepared for. These local citizens now have to balance their traditional self-supporting hunting lifestyle with the lifestyle offered by the modern French Republic,which brings with it not only necessary state welfare, but also alcoholism, betrayal and even suicide.

I believe a common(普遍的) problem with Chinese students’ learning English is that they were not taught to think in English. They have an idea spoken in English and want to translate the idea into Chinese, then they think in Chinese of the proper reply and translate it into English. After a long period of speaking the language, one begins to think in the foreign language naturally. You will learn faster if you begin to think in English at the very beginning of your study. Many students ask me: What can I do to improve my spoken English?
My reply is: The more English you speak, the better English you will speak. There are many things you can do to improve your spoken English. Of course, the best way is to live where English is spoken as a language of the country.
