The 115m Christmas Bird Count is officially underway. The count is an annual investigation of local and migratory(迁徙的)birds and it's organized by the National Audubon Society. From December 14 to January 5, volunteers will gather in more than 2,000 locations in North, Central and South America to count the birds in their area.

Each count takes place in a circle about 24 kilometers wide. The volunteers follow specific routes within the circle and record the number of individual birds and the different species they see there in a single day. The results are sent to the National Audubon Society and later published on Audubon's Christmas Bird Count website. The data collected during the bird count is a key source Of information for ornithologists, scientists who study birds.

This information is used to develop conservation programs to protect bird habitats and the environment /n general. Data from the bird count was also used to determine that three species-the Western screech owl, the rusty blackbird and the Newfoundland red crossbill - should be added to Canada's list of species at risk.

The annual bird count was created to protest another Christmas tradition at the very beginning .in the United States in the 19th century, people would often hold "side hunts" on Christmas Day.

Teams of hunters would compete to see who could kill the most birds or other animals that day. In December 1900, Frank Chapman, an American ornithologist, suggested that instead of hunting birds, people should count them.

Twenty-seven people in 25 locations joined in the first Christmas bird count Last year, more than 70,000 volunteers took part. This year, counts are scheduled to take place in 17 countries, ranging from the Arctic to the Antarctic, with most located in Canada and the United States .instead of taking place only on Christmas day, counts are now held on different days for different areas.

TIME is an American weekly news magazine published in New York City. It was created in 1923 by Briton Hadden and Henry Luce, making it the first weekly news magazine in the US. Hadden was considered carefree, liked to tease Luce and saw TIME as important but also fun. That accounted for its heavy coverage of celebrities(including politicians), the entertainment industry, and pop culture—criticized as too light for serious news.

It tells the news through people, and for many decades, the magazine’s cover depicted a single person. On Hadden’s death in 1929, Luce became the most important man at TIME and a major figure in the history of 20th-century media.

TIME is also known for its signature red border, first introduced in 1927. It has only changed four times since then. The issue released shortly after the September 11 attacks on the United States featured a black border to symbolize mourning. However, this edition was a special “extra” edition published quickly for the breaking news of the event; the next regularly scheduled issue contained the red border. Additionally, the April 28, 2008 Earth Day issue, dedicated to environmental issues, contained a green border. The next change in border was in the September 19, 2011 issue, commemorating the 10th anniversary of the September 11 attacks with a metallic silver border. The most recent change(again with a silver border) was in the December 31, 2012 issue, noting Barack Obama’s selection as Man of the Year.

TIME has a division magazine, TIME FOR KIDS(TFK), which is especially published for children and is mainly distributed in classrooms. TFK contains some national news, a “Cartoon of the Week”, and a variety of articles concerning popular culture that the younger U.S. citizens are interested in. All the stories in TFK are written by young reporters.

In some advertising campaigns, the magazine has suggested that the letters TIME stand for “The International Magazine of Events”.

It is bad to have food stuck between your teeth for long periods of time. This is because food attracts germs(细菌), germs produce acid, and acid hurts your teeth and gums. Flossing(使用牙线) helps to remove the food that gets stuck between your teeth. This explains why flossing helps to keep your mouth healthy, but some doctors say that flossing can be also good for your heart.

It may seem strange that something your do for your teeth can have any effect on your heart. Doctors have come up with a few ideas about how flossing works to keep your heart healthy. One idea is that the germs that hurt your teeth can leave the mouth and travel into your blood. Germs that get into the blood can then attack your heart. Another idea is based on the fact that when there are too many germs in your mouth, the body tries to fight against these germs. For some reason, the way the body fight these mouth germs may end up weakening the heart over time.

Not every doctor agrees about these ideas. Some doctors think that the link between good flossing habits and good heart health is only a coincidence. The incidence(发生率) of two or more events is completely random, as they do not admit of any reliable cause and effect relationship between them. For example, every time I wash my car, it rains. This does not mean that when I wash my car, I somehow change the weather. This is only a coincidence. Similarly, some doctors think that people who have bad flossing habits just happen to also have heart problems, and people who have good flossing habits just happen to have healthy hearts.

The theory that flossing your teeth helps to keep your heart healthy might not be true. But every doctor agrees that flossing is a great way to keep your teeth healthy. So even if flossing does not help your heart, it is sure to help your teeth. This is enough of a reason for everyone to floss their teeth every day.
