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.

    Chinese writer and translator Yang Jiang died early on May 25, 2016 in Beijing at age 104. The longest-living Chinese woman writer, she was known for her modest, subtle and witty writing style.

    Yang became a household name in China for her novels, essays, plays and translated works. Her most popular novel, Baptism, describing a group of intellectuals (知识分子) adjusting to a new society in the early 1950s, has been translated into French and English.

    Yang began learning Spanish in 1959 at age 48, and started to translate Don Quixote in 1962. She was the first to translate Don Quixote into Chinese. The work was stopped twice due to the "cultural revolution". She completed it in 1976, and the Chinese edition was published in 1978 and has sold more than 1 million copies. In that year, the Spanish king and queen visited China, and then-leader Deng Xiao-ping gave the royal couple Yang's translation as a gift. Yang was received by Deng at the Great Hall of the People. While shaking hands, Deng asked her when she had completed the translation. "It's just published," she replied, having no time to tell the full story.

    She was married to Qian Zhongshu, a well-known scholar and author of the best-selling novel Fortress Besieged. Yang's memoir about her family, The Three of Us, written after her husband and daughter died, in 1998 and 1997 respectively, was translated into German.

    Yang never stopped writing. At 94, she started writing the book Walking onto the Edge of Life to reflect on her life. It won China's top book award in 2007. At 100, she was still writing articles for newspapers.

    The number of insects in the world has fallen by 45 percent in the past 35 years. Scientists say this could be dangerous for humans. A report on insect numbers has been published in the journal "Science". It says the human population has doubled since 1980 while the number of insects has nearly halved. One of the biggest reasons for this loss of insects is the act of cutting down trees or burning them. Many of the places where insects live are disappearing because of new cities and land being used for farming. Another reason is global warming. Scientists say that in the UK, the number of butterflies, bees and wasps(黄蜂) has fallen by up to 60 percent. Many countries are worried about the disappearance of them.

    Scientists say the decline in insect populations will lead to many problems for humans. One of the biggest dangers is that there will be fewer insects to pollinate flowers. This means that farmers will have problems growing food. The lead author of the report, Professor Rodolfo Dirzo, said falling numbers of insects could also lead to more diseases in humans. He said rats and mice would have less food to eat so they will move to cities and bring diseases with them. Dr. Ben from London University said we needed to stop more insects from dying. He added that scientists must understand what species(物种) are winning and losing in the fight for survival. He said this knowledge would help us to protect the "helpful" insects.

    Being crazy about perfection(完美) among young people has risen by more than 30 per-cent over the last three decades, a study has found.

    Many of them believe that their environment is very demanding and that others judge them strictly, according to analysis of data from more than 40,000 British, Canadian and American university students from 1989 t0 2018.

    The research, carried out by the University of Bath and York St John University, found that the extent to which young people attach an irrational importance on being perfect, hold unrealistic expectations of themselves and are highly self-critical has increased by 10 percent when compared to previous generations. The authors suggested their findings point to the impact of three decades of neoliberalism (新自由主义) forcing young people to compete against one another.

    Lead author Dr Thomas Curran from the University of Bath's Department for Health said he hoped organizations responsible for guarding the welfare of young people, such as schools, universities, and policymakers who shape the environments in which these organizations operate, would resist the promotion of competitiveness at the expense of young people's psycho-logical health.

    He said, "Rising rates of perfectionism highlighted in this study correspond to three decades of neoliberalism, which has forced young people to compete against each other in an in-creasingly demanding social and economic environment." The study also found the extent to which young people impose (迫使) unrealistic standards on those around them and evaluate others critically has increased by 16 percent.

    The researches defined perfectionism as a combination of extremely high personal standards and overly harsh self-criticism, leading to psychological difficulties.

    Co-author Dr Andrew Hill of York St John University added, "The increase in mental health difficulties among young people makes for a setting for our findings. The higher level of perfectionism may be a key contributing factor to such difficulties. Young people are trying to find ways to cope with increasing demands being placed on them and they are responding by becoming more perfect towards themselves and others."

The Greatest show on Earth

    The Olympic Games are the greatest festival of sports in the world. Every four years, many countries send their best sportsmen to compete for the highest honour in sport. As many as 6, 000 people take part in over 20 sports. For the winners, there are gold medals and glory. But there is honour, too, for all who compete, win or lose. That is in the spirit of the Olympics—to take part is what matters.

    The Olympic Games always start in a bright colour and action. The teams of all the nations parade in the opening ceremony and march round the track. The custom is for the Greek team to march in first, for it was in Greece that the Olympics began. The team of the country where the Games are being held—the host country—marches in last.

    The runner with the Olympic torch (火炬) then enters the stadium and lights the flame. A sportsman from the host country takes the Olympic oath (宣誓) on behalf of all the competitors. The judges and officials also take an oath. After the sportsmen march out of the stadium, the host country puts on a wonderful display.

    The competitions begin the next day. There are usually more than twenty sports in the Games. The rule is that there must be at least fifteen. The main events are in track and field, but there are a few days before these sports start. Each day the competitors take part in different sports, like riding, shooting, swimming, and cross-country running. Points are gained for each event. Medals are awarded for the individual winners and for national teams.

    More and more women are taking part in the Games. They first competed in 1900, in tennis and golf. Women's swimming events were introduced in 1912. But it was not until 1928 that there were any track and field events for women. Now they compete in all but half a dozen of the sports. In horse riding, shooting, and boat racing, they may compete in the same events as men.
