In America, the school life is not easy for us students. There are so many rules we have to follow. When we start school, we get a rule book. There are always teachers looking out for people who are breaking the rules and prefects (长官) are everywhere too.

    The most rules are in the classroom and in the hallways. For example, you can't run or dance around in the hallways. We can't put our bags everywhere in the hallways.

    You can't eat or drink in the classroom or the hallways. Prefects watch you, They can give out duty slips (cleaning the dining hall for about 2 hours).

    If you make mistakes, you will get a detention. You may have to do some work for school. A detention is the most painful. You have to do a lot of tiring and boring things. There are rules for students out of school as well. Boys should not buy take away food in the street if they wear the school uniforms. The school also expects good behavior on public transport and in public places.

A study conducted by the University of Leeds in the United Kingdom suggest that watching cute animals may lead to a reduction in stress and anxiety.

The study examined how watching images and videos of cute animals for 30 minutes affects blood pressure, heart rate(心率) and anxiety. In December 2019, 19 people, including 15 students, joined in the study.

"There were some kittens, there was puppies, there were baby gorillas, there were quokkas —cute creatures found in Western Australia, are often referred to as 'the world's most cheerful animals'." Dr. Andrea Utley, a professor at the University of Leeds told CNN. The study was timed during winter exams, a time when stress is at an especially high level for students, according to Utley.

 The study recorded that the average blood pressure dropped from 136/88 to 115/71, which the study pointed out is "within ideal blood pressure range." Average(平均的) heart rates were lowered to 67.4 bpm, a reduction of 6.5%. Anxiety rates also went down by 35%.

"I was quite pleasantly surprised that during the session, every single measure for every single participant dropped some — heart rate reduced, blood pressure reduced," Utley said. "When they left, they filled the questionnaire(调查问卷) in again and showed that they were feeling less worried."

When questioning the participants, the study found that most preferred video clips over still images, particularly of animals interacting with humans.

Do you like travelling？Travelling is one of the most popular activities during holidays. Modern traffic develops fast，so travelling to different places gets much easier than before. 

Travelling can keep you healthy，and can make your trip happier. But do you know how to keep healthy during a trip？The following information may be useful to you. 

Before leaving

★Wear comfortable shoes，a hat and sunglasses. 

★Take some necessary （必需的） medicines with you. You will need them when you get sick or have other problems. 

★If you do lots of sports like walking or climbing during your trip，you should do some exercise for weeks or months before you leave. While travelling

★Be sure not to eat dirty food or bad fruit. 

★Have enough time to take a rest during your trip. 

★Tap （水龙头） water is not safe，so drink bottled water. When you drink it，remember to clean the cover of the bottle. There may be something dirty on it，such as dust （灰尘）. 

It's important for us to keep healthy. Li Ming gives us a good example. Meals was the time when family members got together. But now fast food and quick meals are threatening(威胁) such family get-togethers. Facing such a situation (情况), Li Ming has a good idea. Though his parents often go to work at night, he also eats the healthiest food. He learns to cook himself.

He takes exercise in the morning. He likes sports such as swimming, running and playing basketball. He goes to bed at ten in the evening and gets up at six in the morning. He can take care of himself. He takes a bath every day and washes his hands before meals. When he has meals, he eats all kinds of healthy food such as fish, eggs, vegetables and meat. He also eats much fruits. So he looks strong. Do you want to be a person like him?
