Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.

Poetry is an interesting form of writing. It is very free, has few restrictions and can be a great way to express feelings. Writing a poem is all about observing the world within you or around you.
To write a poem, first you should begin with an idea or inspiration. Inspiration may come at any time unexpectedly. It may be a specific person, place or thing that causes some sort of strong emotion. It may be more of an abstract idea or release of emotion.
After getting the idea, you can write down everything that comes to mind. Don’t think much and let all feelings pour out. Remember everything can be thrown out later.
Then, you can think about its form and begin to organize thoughts. Poetry comes in many forms, from epic poetry that has a story to dramatic poetry intended to be performed. Try them all out. One will come naturally. Maybe different poems fit different forms. When you write a poem, think about both meter (韵律) and rhythm carefully, which are equally important in poetry. Meter is the fixed pattern of the poem, while rhythm refers to the sound when it is spoken. It is also important to use a lot of descriptive words. Create imagery (意象) with words, trying to make them attractive to all the senses. For auditory (听觉的) interest, try repeating of similar sounds in a sentence or phrase. All of this adds life and interest to a poem.
After you finish your work, don’t be afraid to share your work with others. When others point out your weakness, accept and grow from it.

The history of modern art begins with Impressionism, a movement started in Paris in the mid-1800’s. At that time many artists painted in a very traditional way that involved spending hours in a studio, painstakingly (辛苦地) creating paintings that were extremely detailed. These paintings were sometimes of people or landscapes or historical events. In 1863, Edouard Manet exhibited his painting “Dejeuner sur l’erbe” at the Salon des Refuses. The painting caused a commotion (骚动), thus starting the Impressionist movement. Although Edouard Manet is the declared leader and founder of the group, he was not present at the first group exhibition or any of the other eight collective Impressionist shows. The movement gained more attention in the April of 1874 when Claude Monet, Auguste Renoir, Alfred Sisley, and Jean-Frédéric Bazille formed Society of Artists, Painters, Sculptors, Engravers and began exhibiting outside of the official salon. The same year, the term Impressionism was invented by criticizing (批评的) journalist Louis Leroy to describe their paintings, who worked for the magazine Le Charivari.
The Impressionists often paint out of doors and want to show how light and shadow fall on objects at particular times of the day. Their works are sometimes described as “captured moments” and are characterized by short quick brushstrokes (笔) of colour which, when viewed up close looks quite messy and unreal. If we step back from the Impressionist paintings, the colours are blended together by our eyes and we are able to see the painters’ subjects which often show colourful landscapes, sunlight on water as well as people busy with outdoor activities.
