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.

On March 10th, 2024, a seventh-grade student in Handan, Hebei province, was killed by three of his classmates. School bullying (校园霸凌) became a hit and caused growing attention of the public. Bullying is a big problem at school. Over 200 million students in the world are bullied each year. There is no doubt that school bullying does harm to students' physical health and mental health. It can even threaten (威胁) their lives. Hurting a person's body is the most common kind of bullying, such as hitting or kicking. Saying or writing bad things is also bullying, including laughing at others or giving people terrible nicknames (绰号). In such a situation, it is high time that the students as well as parents and schools take responsibility to solve the problem.

For students, they need to stand up and say "no" to school bullying. When being bullied or seeing bullied behavior, they should tell teachers, parents or the police. Second, legal knowledge is also important. Read law books to protect themselves, instead of bullying back. Third, students should make a good living habit. Don't go to places like KTV. What's more, they should be friendly to classmates to help them when they need help.

For parents, they should pay attention to their children's physical and mental health. In particular, they should focus on the education of their children's good personality and good living habits. Let them learn to love, to contribute (奉献) and learn to be friendly to others.

For schools and teachers, they should stress the school safety work and the school safety education. Besides, more rules should be made to protect the safety of students at school. Meanwhile, they should take care of students and protect the personal information of the students and have heart-to-heart talk with them to help them out.

All in all, students should be given a safe and peaceful place to study. It is hoped that there will be an end to school bullying.

The 24-year-old volunteer, who is known online as Danni recorded(记录) happy times with her students on her phone. Each of the videos attracts thousands of Chinese netizens who are interested in her volunteer experiences.

After finishing university in 2020, Danni chose to work in Africa for a year and then traveled to seven countries. Finally, she stopped in Uganda because of a primary school. She taught children from Grade One to Grade Four. Danni set up different kinds of classes for her students, such as Chinese language learning and cooking.

Sometimes Danni would cook traditional Chinese food for her students, and she also taught them to speak Putonghua. "Their smiling faces gave me energy(能量) and I enjoyed staying with them," she said.

In 2022, Danni arrived in Lebanon and became a voluntary teacher at a local school. This time she taught arts and crafts(手工艺). At the school, Danni built beautiful friendships with the children. They would run to give her hugs(拥抱) or small presents every morning, and would invite her to their homes.

She had some interesting activities in her teaching such as paper cutting and the making of paper ice cream. Some of her students were good at these and could finish the handicraft works quickly, while some needed a bit of help. The good thing was that they all worked hard.
