How green are you? Do you know how to be green?

    We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.

    Reduce

    Reduce means "use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we buy things, choose local products if possible, and try not to buy too many things from abroad.

    Reuse

    Reuse means "use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china (瓷器) cup and a lunch box because you can use them again.

    Recycle

    Recycle means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

    So please remember these three words: reduce, reuse and recycle.

Animals

    Corona viruses are common in animals. Sometimes, animals get infected (感染的) with these viruses which may then spread to human beings. To protect yourself, you should not visit live animal markets or have direct contact with wild animals. Stay away from raw meat, animal organs and other undercooked animal products.

    When an infectious pet was found in Hong Kong, some may wonder if one can get virus from their pets. Until today, there is no evidence that a dog, cat or any pet can transmit (传播) COVID-19. Please do not kill or give up pets!

Touching surface with virus

    Studies suggest that COVID-19 virus may stay on surfaces for a few hours or up to several days. However, the number may change under different conditions such as type of surface, temperature or the environment.

    If you think a surface may be infected, clean it with ethyl alcohol (酒精). After touching it, clean your hands with alcohol or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

Package (包裹)

    Before delivering to your home, a package has been moved, travelled, and exposed to different conditions and temperature. Therefore, the possibility of being infectious because of your package from COVID-19-reported areas is rather low. There is no need to send your package back.

Smoking

    An article posted on Wechat recently says that cigarette can protect smokers from COVID-19 and thus make cigarettes sell very well. It is an online rumor (谣言)! As has been known, smoking harms people's health. It weakens the immune system and worsens diabetes and blood pressure. No smoking is still a must!

Transportation

    According to Feng Luzhao, an expert from the Chinese Center for Disease Control and Prevention, the major routes of transmission are still through respiratory droplets and direct contact. In order to protect yourself in underground station, wearing a mask and keeping your hands clean are good ways. People are also encouraged to use a personal transportation card or pay for the ticket via an app. After taking public transportation, washing hands is necessary.

Have you ever wondered what an American high school is really like? This article will describe a typical (典型的) high school and its students.

A typical American high school has several large buildings and enough space for about 1,500 students. Every student is given a locker. When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather loan (租借) than buy them. Students must pay back if they lost any of them.

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. Sometimes their parents drive them to school.

When they turn 16 years of age, most take a free driving class at school for one term. If students' exam passing grades in the class and also pass their state driver's exam, they can begin driving themselves to school.

Each day, students take six or seven classes. They must take science, math, English and social studies. They can choose art, homemaking, fashion design and other classes. In some schools students are required to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because cache teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The regular school day usually ends early in the afternoon. After school more than half of the students take part in after-school activities. These activities include sports, specially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, photograph or student government.

Think about the colors of fruit and vegetables: the red of tomatoes, the orange of carrots, and the purple of grapes.
