Taking about three times as much vitamin D as the norm may lower an individual's risk of developing colon, breast or ovarian cancer, a study says.

Americans typically take 320 units a day of the vitamin，consisting of 200 from food and 120 from supplements. Daily intake of about 1 ， 000 units may cut the odds of getting colon cancer by about half,and the chances of getting breast or ovarian cancer by about a third, ac?cording to the researchers.

Vitamin D supplementation could reduce cancer incidence " at low cost，with few or no side effects”，the researchers said in an article appearing in the February 2006 issue of the American Journal of Public Health.

"The strongest effect is for colorectal cancer,”said lead author Cedric Garland, 59, a pro?fessor of family and preventive medicine at University of California-San Diego, in a telephone interview Tuesday. Garland said.

The U. S. National Academy of Sciences recommends daily vitamin D intake of at least 200 units for adults 50 or younger; 400 units at ages 51 to 70 ，and 600 units for people 71 or older. The upper limit for safe intake is 2， 000 units daily. Thus,the dose recommended by the re?searchers is beyond what most people now get and what the government recommends.

A glass of milk contains about 100 units of the vitamin, Garland said. While cod liver oil is rich in vitamin D，it also contains a lot of vitamin A and the two vitamins compete for reception by the body,Garland said. He doesn't recommend cod liver oil as a source of vitamin D.

To ensure getting 1 ， 000 units of vitamin D, most people probably can take two 400-unit tablets，with the other 200 units coming from foods such as salmon，orange juice，yogurt and cheese, Garland said. Getting enough vitamin D through supplements would cost less than 5 cents a day，he said.

Although sunlight helps the body produce natural vitamin D，the researchers urged getting the minimum of 1， 000 units through food and supplements. Dark-skinned people, who need more sunlight to make vitamin D.are at increased risk of vitamin D deficiency，the scientists said.

Animation means making things which are lifeless come alive and move.

Since earliest times，people have always been astonished by movement. But not until this century have we managed to take control of movement，to record it，and in the case of anima?tion，to retranslate it and recreate it. To do all this，we use a movie camera and a projector(放映机) .

In the world of cartoon animation, nothing is impossible. You can make the characters do exactly what you want them to do.

A famous early cartoon character was Felix the Cat,created by Pat Sullivan inAmericain the early nineteen twenties. Felix was a wonderful cat. He could do all sorts of things no natural cat could do like taking off his tail，using it as a handle and then putting it back.

Most of the great early animators lived and worked in America, the home of the moving picture industry. The famous Walt Disney cartoon characters came to life after 1928. Popeye the Sailor and his girl friend Olive Oyo were born at Max Ficischer in 1933.

But to be an animator, you don't have to be a professional(专业人士) . It is possible for anyone to make a simple animated film without using a camera at all. All you have to do is to draw directly on to an empty film and then run the film through a projector.
