    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.
