Vitamin B could help reduce the effects of the dangerous type of air pollution, according to a new study published on Monday. In the first study of its kind, a team of international researchers looked into the damage caused by one of the pollutants that have the severest impact on health—PM2.5.

    They found that Vitamin B supplement could effectively reduce the impact of the tiny particles     （颗粒）on the human body, although they stressed that the research was in its early stages. According to the WHO, 92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level. So it's urgent to find a solution to the problem.

    According to this study, published in the PNAS, 10 volunteers were initially exposed to clean air and given a placebo (安慰剂）to check their baseline responses. The group then kept on taking placebos tor tour weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars passed every hour. The bad air was delivered to the volunteers through an "oxygen type" face mask. The experiment was then repeated, with each volunteer taking a Vitamin B supplement daily, made up of 2.5mg of folic acid, 50mg of Vitamin B6, and l mg of Vitamin B12.

    Vitamin B6 can be found in liver, chicken, nuts and other things, and Vitamin B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of Vitamin B supplements — the damage of PM2.5 effects by 28-76%. The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5, the researchers said.

    My dad is the kind of parent that expects my best. He would never be angry if I failed at something as long as I tired. He never changes his mind after he makes it, which sometimes makes him seem too stubborn. My dad's strictness comes from the way he was raised. He grew up working long hours on his family farm. His dad was bad-tempered, and he would get angry enough to throw wooden boards at my dad when he did something wrong. In high school, my dad woke up at four in the morning to get his chores(家务杂事)done and walk to school so that he would make it to basketball practice by five.

    Through all of the duties my dad had at home, he played three sports and went to school on top of it. school would have been easy, but my dad had dyslexia(读写困难)which made it nearly impossible for him to read. Since dyslexia wasn't recognized back then, every teacher my dad had passed along thinking that he was just unable to learn. My dad struggled in school until one teacher took the time to sit down and teach him how to read and write.

    The best part about my dad is his attitude toward daily life. even though he likes things once right, he also knows how go to with the flow and have a good time. My dad doesn't worry about things he can't control. When he comes home from a terrible day at work, he always puts on a smile on his face because he knows family is a lot more important than any other tings.

    I know that I get my best qualities from my parents and the way they raised me. My dad has shown me that with discipline and hard work I can achieve anything, and have fun while doing it.

    "Tomorrow is another day" — this line has impressed various people at various times. It's now 70 years after it appeared in the film, but it still seems to hold its power especially during an economic downturn.

    The phrase comes from a film adaptation of Margaret Mitchell's successful 1936 novel Gone With the Wind. It's set in the American South and tells the story of a strong heroine, Scarlett O' Hara, who struggles to find love during the Civil War and, afterwards, of her strength in surviving the war and its hardships.

    Love story

    In a moment of despair, Scarlett finally realizes that her love belongs to Rhett Butler. For many audiences, it is the theme of love and struggle that has kept the movie alive. While the burning of Atlanta might seem irrelevant (不相关的) to today's viewers, the timeless theme of love keeps its ability to touch people.

    With a promise to her lover still in her mind, Scarlett chooses to stay in the midst of war and take care of Melanie. But her heart is broken when Rhett just walks away, leaving the woman that he once loved with cruel words, "Frankly, dear, I don't give a damn." (毫不在乎)

    Great epic (史诗)

    The film shows the love-hate relationship of these characters, but also American history, the fall of the Confederacy and the following period of Reconstruction in the South. The background made this film a true classic in the epic genre.

    When the film opened after World War II, French viewers loved it, and it reminded them of their fight against the Nazis. In 1940 Shanghai, during the War of Resistance Against Japanese Aggression (侵略), people stood in line for hours to watch this film, and saw the same suffering they were having as well as the hope and possibility of building a new homeland from the ruins. Each nationality could identify with the story and see it as a victory. In fact, Gone With the Wind never lost its charm and ability to inspire and amaze.

    Biggest of all time

    The film had five directors, 15-plus screenwriters, and an unexpected $3.9 million budget. The film brought in $200 million, which makes it the biggest selling film of all times in North America. It also won 10 Academy awards in 1940.

    Elephants might be the most well-known and well-loved animal in African wildlife. But conservation (保护) of the African elephant still faces special difficulties. While the elephant population is half of what it was 40 years ago, some areas of Africa have more elephants than populated areas can support. That's why AWF scientists are studying elephant behavior, protecting habitats and finding ways for humans to live peacefully with elephants in Africa.

    Years ago, overhunting and the ivory trade were the biggest threats to elephants' survival. Luckily, ivory bans (禁令), hunting rules and protected areas protect elephants from these dangers today.

    The 21st century brings a different challenge to elephant conservation—land-use. Elephants walk across borders and outside parks and other protected areas. So they often destroy crops, causing conflicts (冲突) between local farmers and these big animals.

    Successful conservation strategies (策略) must allow elephants to walk freely in their natural habitats while reducing conflicts between elephants and local people.

    AWF researchers are searching for a way to give both elephants and people the space they need. The AWF is collecting information on elephant habitats and behavior. The information they gather will help to develop the widest possible space for elephants.

    The AWF is helping elephants by protecting their habitats. And they also work with local famers to improve their life in order to encourage them to protect rather than destroy elephants.

    Over the centuries the French have lost a number of famous battles with the British. However, they've always felt superior in the kitchen. France has for centuries had a reputation for cooking excellence, and Britain for some of the worst cooking in the world. But according to a recent survey, that reputation may no longer reflect reality.

    In the survey, 71% of the Britons said they cook at home every day, while only 59% of the French said they cook daily. British home cooks spend more time cooking each week and also produce a greater variety of dishes than French home cooks.

    The reaction in London was predictably enthusiastic. British food has greatly improved since the 1990s. Once upon a time, the menu for many family meals would have been roast beef, potatoes and over-cooked vegetables, but not now. Home cooks are experimenting with the huge range of ingredients now available in British supermarkets and are preparing all kinds of new dishes, using the cookbooks that sell millions of copies every year. As a result, there's much more diversity in British food now, compared to French food, which tends to be very traditional.

    Some French people say that the survey did not show the whole picture. They agree that during the week French women don't cook as much as they used to because most of them work and don't have much time. They tend to buy ready-made or frozen dishes, but many of them make up for it on the weekend. There's also a difference between Paris and the countryside. It's true that people in Paris don't cook much, but elsewhere, cooking is still at the heart of daily life.

    For many French people, opinions about British food have not changed. When Bernard Blier, the food editor at a magazine, was asked about British food, he replied: "I don't go out of my way to try it. It is not very refined. You can say that I'm not a fan at all."

Let's face it. No one drinks diet sodas for the taste. People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it. Yet it seems to have exactly the opposite effect, according to a new study.

Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet sodas. "What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler.

The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly 10 years.

While the findings are surprising, they also offer some explanations.

Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet sodas, they don't lose weight at all. "We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers.

So why would diet soda cause weight gain？No one knows for sure yet, but it could be that people think they can eat more if they drink diet sodas, and so over﹣compensate (补偿) for the missing calories.

A related study found some sweeteners (甜味剂) raised blood sugar levels in some mice. "Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P. Hazuda, professor at the University of Texas's school of medicine." They may be free of calories, but not of consequences. "
