Think about vitamin D when you're catching up on summer rays. It's sometimes called the “sunshine vitamin” because it's produced in your skin in response to sunlight. Vitamin D is a fat-soluble (脂溶性的) vitamin in a family of compounds that includes vitamins D-1, D-2, and D-3. It can affect as many as 2,000 genes in the body.

    Vitamin D has several important functions. Perhaps the most vital are regulating the absorption of calcium and phosphorous（磷）, and promoting normal immune system function. Getting enough vitamin D is important for normal growth and development of bones and teeth, as well as improving resistance against certain diseases.

    In addition to its primary benefits, research suggests that vitamin D may also play a role in: reducing your risk of multiple sclerosis（多发性硬化）, according to a 2006 study published in the Journal of the American Medical Association decreasing your chance of developing heart disease, according to 2008 findings published in Circulation helping to reduce your possibility of developing the flu, according to 2010 research published in the American Journal of Clinical Nutrition regulating mood and warding off depression losing weight or preventing heart disease.

    How do you get it? Your body produces vitamin D naturally when it is directly exposed to sunlight. A little can go a long way. All you need is 10 minutes a day of midday, pre-sunscreen sun exposure,especially if you have fair skin. Besides getting vitamin D through sunlight, you can also get it through certain foods and supplements to ensure adequate levels of the vitamin in your blood.

    He is both a great director and a great animator (卡通片制作者). He is Japan's Walt Disney.

    Hayao Miyazaki, the 72-year-old Japanese master of fantasy animation (奇幻动画), one of the most respected animation directors in the world, announced his retirement on September 6. Here are some key words about his films.

Good and evil (邪恶)

    Miyazaki rarely tells stories in simple good and evil. The worlds he creates tend to be complex (复杂的) and unclear. The bad figures often don't seem so bad once you get to know them. Miyazaki has explained that the lack of clear good and evil is because he sees the 21st century as a complex time, in which old ideas need to be re-examined, even in children's films.

Children

    The heroes in Miyazaki's films are usually children or teens, more often young girls. Sometimes they can see the spirit world; they are curious and friendly, even to strange creatures. The stories often deal with growing up.

Sky and water

    Two of Miyazaki's great loves are the sky and water, and he uses them in related ways. Flight is a forever theme — Miyazaki has never done a film without flying of some kind. His imagination seems to fly and leave behind the pull of gravity (重力), a force and control that he feels a bound (束缚) from setting him free.

    Water is another way for Miyazaki to fight gravity. In his films he likes the unexpected floods with crystal-clear water, and objects floating on the surface seem to be supported by magic.

Peace

    Miyazaki's negative view of the war goes far more than surface deep. Violence is usually seen as wrong and painful, and Miyazaki's heroes are often peacemakers.

    Once there were two mice. They were friends. One mouse lived in the country; the other mouse lived in the city. After many years the Country mouse saw the City mouse; he said, "Do come and see me at my house in the country." So the City mouse went. The City mouse said, "This food is not good, and your house is not good. Why do you live in a hole in the field? You should come and live in the city. You would live in a nice house made of stone. You would have nice food to eat. You must come and see me at my house in the city." The Country mouse went to the house of the City mouse. It was a very good house. Nice food was set ready for them to eat. But just as they began to eat they heard a great noise. The City mouse cried," Run! Run! The cat is coming!" They ran away quickly and hid. After some time they came out. When they came out, the Country mouse said. "I do not like living in the city. I like living in my hole in the field. For it is nicer to be poor and happy, than to be rich and afraid."

Brazil sports are out of control! Brazil may be one of the most sports­crazy countries in the world. Whether you are into watching or playing, Brazil sports have a lot to offer everyone.

Football in Brazil is more than a sport. It's a way of life. Football is popular in Brazil for several reasons. One reason is that it is fast paced and fun to watch. This is the reason why the World Cup Soccer is the most watched sports event in the world aside from the Summer Olympics. Also, you don't need anything to play soccer except for something to kick, and a big area in which to play. Few will argue if you say that Brazil leads the world in football. No nation has won as many world cups as Brazil.

Volleyball is a close second in Brazil sports. In the world of international volleyball, Brazil wins many championships of all kinds, including indoor and beach volleyball. Brazil has nearly 5,000 miles of coastline. If you go to a beach in Brazil, there will always be a volleyball game going on somewhere, and usually two or three.

Footvolley was created in Brazil in the 1960s. It is a mix of football and volleyball, where the players must use their feet and head to get the ball over the net and into the opponents' court, and is also played in sand. It is one of the most popular beach sports in Brazil.

Swimming, tennis, rugby, boxing, judo, sailing, golf, surfing, and handball are all greatly popular in Brazil.
