Thang-ga is a special kind of painting. It started from the Tang Dynasty. Thang-ga paintings have attracted the public's attention in recent years. At the same time, the Chinese government has also tried hard to protect the culture.

    Thang-ga paintings were developed in the 7th century in the Tibetan area. The paintings are colourful and the paints used in Thang-ga paintings are different from those in other paintings. Because of the special environment of the Tibetan Plateau (高原) and the excellent painting skills, the colours of Thang-ga paintings look special. The paints in Thang-ga paintings in the past were made from minerals, including gold, silver, as well as some plants. Since they were made by hand, the beautiful colours could last for hundreds of years.

    However, with the development of machines, people now use cheaper and more easily-made chemicals to make paints. The traditional paints in Thang-ga paintings needed too much work and there were many secret methods. Later people stopped making the paints and forgot about them. So the skills were almost lost.

    Three kinds of bears live in the United States. They are the black bear, the brown bear, and the polar bear.

    Black Bears

    Black bears are the most common of the three. They live in forests in many different parts of the country. Even though they are known as black bears, they are not always black. Sometimes they are brown or tan (黄褐色的) , and a few are even white. Black bears are usually about five or six feet long, and they are the smallest of the three kinds of bears.

    Brown Bears

    Brown bears are found in a few western states and in Alaska. They live in forests as well as in open areas called the tundra (冻土地带). Brown bears are usually light or dark brown and can grow to be very large. In fact, some are eight feet long!

    Polar Bears

    Polar bears can be found in Alaska. It is in a cold area near the North Pole called the Arctic and there are no trees there. Polar bears are white, and they are the largest of the three kinds of ears. They are a little longer and usually heavier than the brown bear.

    Other Interesting Things

    Bears eat different things. Black and brown bears eat fish and other kinds of meat, roots, and berries. Polar bears eat fish, other meat, seaweed, and grass. All three types of bears eat as much food as they can find just before winter. Then during the cold months, they sleep in caves or hollowed-out trees called "dens". They keep them warm. Winter is when the female bears have their babies. All three types of bears have between one and four cubs (幼兽). The cubs are born while the mother bear sleeps!

    All people are afraid of bears. However, bears are actually shy. Most bears try to stay away from people, but still, bears can be dangerous at times.
