Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.

    {#blank#}1{#/blank#} Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.

    For years many doctors thought that repressing anger was more dangerous to a person's health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙).They speed the heart rate, raise blood pressure, or sugar into the blood, etc. {#blank#}2{#/blank#}

    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.

    {#blank#}3{#/blank#} They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “{#blank#}4{#/blank#}”  Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.” Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. {#blank#}5{#/blank#}

    Green spaces within and around city schools improve the mental development of young children, a study has found. The findings may partly be explained by reduced exposure to traffic pollution, experts believe. Other influences could include the psychological effect of having views of fields and trees rather than roads and buildings.

    The Spanish researchers found each degree of increase in surrounding greenness led to a 5% improvement in the development of short-term, or working memory over a period of one year. It also improved the progress of "superior working memory”—the ability to update memories. with changing information—by 6%，and reduced inattentiveness. Computer analysis suggested that carbon from traffic might account for up to 65% of the trend.

    The researchers carried out mental performance tests on 2, 593 children attending 36 primary schools in Barcelona every three months for a year. Over the study period, participants' working memory increased by an average of 22.8%, and superior working memory by 15.2%, while inattentiveness decreased by 18. 9%.

    The researchers wrote, "Approximately one half of the world population lives in cities, and by 2030, three in five persons will live in urban areas worldwide, Urban areas are a network of non-natural built-up structures with increased pollutant levels and less green environments. Children's exposure to these pollutants has been associated with harmful impacts on their mental development. Our findings suggest a beneficial impact of greens paces exposure on mental development. "

    British experts said the study was interesting, but pointed out some limitations. Professor Andy Jones, from Norwich medical school, said, “The measure of green space used was the number of plants in the neighborhoods of the children and their schools. It was not a direct measure of usable green spaces, like public parks, although they will be included. " Dr Ross Cameron, at the University of Sheffield, said, “The authors suggest a causal link between air quality and green space. They admit, however, that this factor only seems to explain part of their correlations(相互关系), ”

    For over 70 years, UNICEF has been putting children first, working to protect their rights and provide the assistance and services they need to survive and develop all over the world.

    It's the end-of-year giving season, and UNICEF has lots of good news to share about the influence its supporters have had on the lives of children. Thanks to its generous donors, UNICEF has helped save more lives than any other humanitarian organization.

    Monthly donors are a major reason why UNICEF can make that claim, according to Karla Coello, UNICEF USA Senior Director for Monthly Giving. “Last year, UNICEF responded to 377 humanitarian emergencies, from conflicts to natural disasters,” says Coello. “Emergency appeals bring in important revenue - but after the emergency, there are still a lot of things children need to make life bearable. That's what our monthly donors provide.”

    When drought destroys crops, conflict forces families from their homes, an epidemic breaks out or a disaster strikes, children suffer most. And in some countries, even the best of times are dangerous for its youngest citizens. Every day more than 15,000 children under 5 die from preventable causes.

    Protecting children before, during and after a crisis requires a reliable source of funding. The constant stream of revenue provided by monthly donations enables UNICEF to reach children with what they need most when they need it, prepositioning emergency supplies before a disaster strikes and continuing to build sustainable solutions after an immediate crisis has subsided.

    Monthly giving is also important to funding large-scale interventions(介入). Thanks to UNICEF's global immune campaigns, the world is now nearly free of polio(小儿麻痹症)and there are only 14 countries where mothers and children still face maternal and neonatal tetanus(破伤风)deadly threat. And UNICEF programs in 120 countries are helping to prevent and treat malnutrition, which is linked to nearly half of all deaths of children under 5.

    “UNICEF USA monthly donors are our most engaged, most dedicated supporters,” says Rebecca Volpe, UNICEF USA Manager, Monthly Giving. “So we do our best to make them feel appreciated by keeping them thoroughly updated about the powerful impact they are having and showing them how much they matter to us.” In turn, monthly donors tend to be dedicated supporters. “Protecting children - giving them opportunities to play, learn, feel safer, heal - is critical to us,” explained a survey respondent, expressing a commitment to children that UNICEF USA's Monthly Giving team sees every day.

    Supporters who sign up with UNICEF USA to give monthly automatically become members of the Guardian Circle, which affords them benefits, including:

    Annual statements to make tax time easier

    An easy-to-use donor access that simplifies modifying gift amounts, updating payment methods and making other changes, including the timing of donations with the option to cancel at any point

    Targeted communications in the form of monthly statements and a quarterly 8-page newsletter with stories from the field.

    A team available to answer questions via email or phone.

    “We have some donors who are on fixed income, others who can afford to make considerable monthly donations," says Coello. “Whether you give $5 or $700 a month, you are super important to us. What's important is that they all really want to give and help children. And that's amazing.”

    It can be time-consuming and difficult to track charitable donations. At end of year, Guardian Circle monthly supporters receive one statement that makes filing tax returns easier - and it's always delightful to see how much good has been done for the world's most vulnerable(受伤害的)children.

    Italian Joseph Caspar Mezzofanti was said to have spoken more than 38 languages fluently at the time of his death in 1849, a skill that would have been useful in today's globalized economy. Unfortunately, when it comes to the high school Spanish lesson in the decades, most people nowadays have remembered that there is nothing more complex than "Donde esta la biblioteca". So we set out to uncover what's involved in learning a foreign language and which methods work best.

    Some advertisements say that some language learners believe they're just a 15-minute audio tape away from becoming UN interpreters. But experts say these get-fluent-fast programs are a complete sham." Actually, there is hardly a shortcut that can do that," says Dekeyser, a professor of second language acquisition at the University of Maryland." The only way to learn a language is to make quite a bit of effort on a daily basis."

    Many experts agree that the ideal learning method for language learners really depends on the individual." Find the method that works for you and stick with it," says Simcott, a polyglot who has professionally worked in over 14 languages at once for the British Foreign Service." If audio works for you, do audio. If you like taking classes, do classes. But remember to keep practicing every day."

    However, not all people are created equal. Some may have talent for language learning, but it doesn't mean they can passively await fluency. "Practice is an effective learning method," says Davidson." The more time that you spend during the day speaking your second language, the better at it you're going to be."

    Learning from multiple people is also a good way, especially when you are attempting to cultivate a native accent. "When you are exposed to a lot of people, you get a much better sense of what the sound of a word is supposed to be," says Davidson. "You avoid exposing yourself to what could be features in one individual's speech patterns."

    Scientists in New Zealand have found fossilized (化石的) leg bones from a penguin believed to have been about the size of an adult human. The previously undiscovered giant penguin species likely stood about 1.6 meters tall and weighed up to 80 kilograms.

    The penguin existed about 60 million years ago. The bones are believed to be from the oldest of several species of giant penguins that lived after dinosaurs died out. A fossil hunter found the bones last year in the Waipara River bed near the city of Christchurch. The bones are from the animal's legs and feet. Scientists confirmed that the bones came from a newly discovered species.

    Paul Scofield is senior curator (馆长) at New Zealand's Canterbury Museum. He co-wrote a paper on the discovery. He said that the bones are an important find. They show that the species is similar to another giant penguin found in Antarctica in 2000. The latest discovery, he said, helps show a clear connection between the two areas during the Paleocene period. This period lasted from 66 million to 56 million years ago.

    Scofield said the penguins were able to grow larger after entering a new development period following the extinction of dinosaurs, sea reptiles and huge fish. Scofield added that the giant penguins became extinct within 30 million years, as large mammals began to rule the waters.

    John Cockrem is a penguin expert at the country's Massey University who was also not involved in the research. He said the discovery helps add to what we know about giant penguins. He said it also confirmed New Zealand as the penguin center of the world.

    New Zealand is believed to have been home to many giant bird species that later disappeared. These included the world's largest parrot, a giant eagle and an emu-like bird called the moa. Recently, Canterbury Museum announced the discovery of an unusually large parrot believed to have lived about 19 million years ago. Scientists say the bird stood about one meter tall.

A new study examines possible harm caused by microscopic pieces of plastic that end up inside people's bodies. These materials -known as microplastics and nanoplastics - can enter the body through the air or in food or drinks.

One new study suggests the buildup of such plastics inside the body can increase the risk of a stroke, heart attack or death. But the researchers noted the evidence presented cannot prove a direct link between tiny plastic materials and heart problems.

The study involved 257 people who had medical operations to clear blocked blood vessels （血管） in their necks. Italian researchers examined the fatty buildup the doctors removed from the carotid arteries, which supply blood and oxygen to the brain. Using two methods, they found evidence of plastics-mostly nanoplastics that cannot be seen-in the artery plaque（动脉斑块）of 150 patients. No evidence of plastics was seen in 107 patients.

The team followed these people for three years. During that time, 30 individuals, or 20 percent of the group with plastics, had a heart attack, stroke, or died from any cause. These rates dropped to about eight percent among those with no evidence of plastics. Research results were recently published in a study in the New England Journal of Medicine.

The researchers admitted their study was very small. For example, it only looked at people with narrowed arteries who were already at risk for heart attacks and stroke.

Steve Nissen is a heart expert at the Cleveland Clinic in the state of Ohio who was not part of the study. He told the Associated Press he thinks the team's estimate that the risk of heart attack, stroke or death was four times greater seems too high. "It would mean that these microplastics are the most important cause of coronary heart disease （冠心病） yet discovered. And I just don't think that's likely to be right," Nissen said. "Maybe, it's just a wake-up call that perhaps we need to take the problem of microplastics more seriously." Nissen added.
