    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.

    Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.

    My earliest memories of my father are of a tall, handsome, successful man devoted to his work and family but uncomfortable with his children. As a child I loved him, as a school girl and young adult I feared him and felt bad about him. He seemed unhappy with me unless I got straight A's and unhappy with my boyfriends if their fathers were not as "successful" as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

    On the first day of my visit, we went out with one of my father's friends for lunch at an outdoor cafe. We walked along that afternoon, did some shopping, ate at the street table, and laughed over my son's funny facial expressions. Gone was my father's critical(挑剔的)air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

    The next day my dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I'm at last seeing another side of my father. And in so doing, I'm delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he is.

    Most of us will be familiar with the traditional talent show set-up: thousands of hopefuls line up outside the audition(试音)room, wait for hours to go in and perform for a group of judges. Then these potential pop stars could be lucky and get through to the next round, or they might hear the command, "Sorry, it's a no from me. But what do the judges actually bring to a talent show?

    Music talent show judges attract millions of viewers each week to their programs. As public figures, they play an important part in advertising campaigns for these programs. They often receive high salaries and can be moody. Are they really worth the expenses and difficulties that they cause? One solution might be to replace them with computers.

    Can computers really match human judges? Scientist Dr Nick Collins and his team at the University of Sussex think they can. Dr Collins has been working on a project that involves programming three computerized judges that he says would be far more consistent in their judgment of musical performances. Employing a special programming language, Dr Collins's digital judges can be trained up by "listening" to particular musical styles. After they have been listening for a while, the programming language allows these judges to spot the specific features of the music, including the voice quality, the rhythm etc. Collins says, “The judges' listening capacity is not yet as good as a human ear, but they won't be as moody as some human reality TV show judges.”

    Maybe that is the problem with this electronic musical innovation. Real human judges on talent shows interest us with their personality, decisions and catchy phrases. Will a computer program be able to do the same?

    Everyone can try his best to achieve something. We don't need to be the best, but to challenge the limits of what we are capable of. I gained this belief from my third grade teacher, the most special, honored, trustworthy, and beloved person in my life.

    Mr. Myrus was always perfectly dressed and spoke with the belief that talking to an eight-year-old child didn't mean he had to sacrifice proper statements or grammar. And he was demanding, but he wasn't unreasonable or cruel. He simply felt that no matter what your best was, you should achieve it.

    Luckily enough, I met him again as my eighth grade math teacher. I was not, nor ever will be, gifted in math. I remember my struggles in class. “I don't know the answer,” I would say. "I can't do it!" “Perhaps you don't know the answer,” he would say quietly. “Do you think we might figure it out together? How do you know what you can do if you don't have a try?”

    Mr. Myrus lived around the corner, and I would often stop by to talk while he worked in his garden. I knew there was someone who let me know that if I had really tried, that was enough. “Don't be so hard on yourself,”he'd say.“ Stop blaming yourself. Did you try your best? Well, then you're not a failure,” he often told me these words.

    Mr. Myrus died in 1978. I had never thought about his death. He was too young. I felt sorry. But when I think about him now, I don't feel so sorry. He taught me to be kind, not only to others, but to myself. He taught me my own value. He taught me about honor, about truth, and about doing my best and he also taught me that all feelings and beliefs have dignity and deserve respect. And of all the things I know, I believe that we can't all be “the best”, but we can, each of us, be our best. And I know that's true because Mr. Myrus told me that.
