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.

Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

    Horses are beautiful animals. They can be in different colors, and can run quickly. People like to watch horses because they are strong and beautiful.

    Horses are mammals (哺乳动物). The mother horse usually has one baby in spring, and feeds the baby milk. Horses have long legs and big eyes, so they can see almost all the way around them. They can walk and jump.

    Horses can live up to 20 or 25 years. Sometimes people can tell how old a horse is by looking at its teeth! They usually sleep by standing up. Horses only need about three hours of sleep per day!

    People need to take care of the horses "hooves". If a horse is doing a lot of walking on hard ground, people put horseshoes on them. When the hooves need trimming (修剪), people take off the horseshoes, and then give them new ones.

    For food, horses eat food such as grass, corn, apples and carrots. They don't eat other animals. Their stomachs are small, so they eat a little at one time, but they eat many times.

    Some horses are very famous. For example, Bucephalus, the famous horse of Alexander the Great. When Alexander was a boy, he got a horse. Nobody else could ride on it. Alexander named the horse Bucephalus and the horse carried him in many battles (战役). Here is another example. Napoleon had many horses, and Marengo became famous after Battle of Waterloo.

Shandong Province held the 36th Weifang International Kite Festival on the third Saturday of April in2019. A lot of kite fans from all over the world went there to join in the interesting festival on that day. Different kinds of beautiful kites flew in the sky.

Over 2, 000 years ago, a man named Gongshu Ban from Shandong Province invented a kite. It was made of bamboo. In the following centuries, kite-making developed well in China.

The first Weifang International Kite Festival was celebrated in 1984. In 1983, the Chairman of the Seattle Kite Association David Checkley took part in a kite show and later he visited several kite manufacturers(制造商). He found that kites made in Weifang were the best. He suggested holding the first Weifang International Kite Festival there. After that, Weifang began to hold it in April every year.

At the fifth festival, Weifang became known as the" Kite Capital of the World". Today, Weifang is home to over 300 kite factories. People in Weifang sell their products to about 40 countries and regions(地区) , making up 85 %of the domestic(国内的)markets and 65 %of the foreign markets.

However, there are also some problems. "Few people would like to learn about traditional kite-making," said Yang Hongwei. Yang's grandfather was once one of the best kite makers in Weifang. Nowadays, Yang still uses traditional ways and skills to make kites. In her opinion, only traditional things can last for a long time. Since the1990s, she has travelled to many countries to teach and take part in kite shows. "I won't stop teaching the ways of making kites as long as someone wants to learn. Meanwhile, the government should hold more kite festivals in China or even overseas, "she said.
