I'm Andy. I study at a school in Beijing. There are lots of rules(条例) in my school. We have to wear school uniforms every day, and we can't wear rings. We can't arrive late for school. We can't talk in class. After class, we can't run in the hallways. I can follow most of them, but I can't follow some.

    My cousin Mike is in a school in the USA. In his school, students can't bring alcohol(酒) to school Students can't smoke. Students can't colour their hair, and boys can't have long hair. It's easy for Mike to follow them.

    My e-friend Julie studies in a school in Canada. In her school, students can't eat in the classroom. They can't listen to music in class. Julie thinks she can obey these rules.

    We don't like some of the rules, but most of the rules can help us and we have to follow the rules.

    It's Monday today. When Alice gets up in the morning, she finds everything is white. It's snowing. It looks very cold. So she puts on a warm sweater. After having some milk and bread for breakfast, she wants to ride her bike to school. But her mom tells her not to do that because there's too much snow on the road. Then she walks to school. There's a P. E. class on Monday. Alice is very happy because she can play with snow with her friends.

    You must have heard about jogging(慢跑)as a popular way of keeping fit, but what about plogging? Plogging is a mix of jogging and picking up litter, coming from the Swedish phrase "plocka upp". It started as an organized activity in Sweden around 2016 and then spread to other countries step by step. For exercising, plogging is much better than simply running, because it provides changes in body movements by adding bending(弯曲), squatting(蹲) and stretching(伸展).

    As 2018's hottest fitness way, plogging has become popular in more than 40 countries, from the US to France and Australia to Thailand. The idea of plogging is to pay attention to environmental protection as well as physical health — to care for Mother Nature as well as your body. "I run a lot and I love to spend time in nature. When I find litter out in the woods, it makes me sad and a bit angry. Plogging is a natural way to do something about that," Tesch said." It's so easy to just pick up the litter and put it in the nearest bin, and it makes you feel that you're making a difference!"

    Have you noticed people jogging while carrying trash bags recently? Or running along with hands full of dirty plastic bottles? You might do soon! Because plogging has reached China. Olivier, a Frenchman married to a Chinese girl, began promoting(促进)plogging in Huizhou, Guangdong Province, back in April. He and his wife were the only ones doing it at first, he said, but the craze soon caught on. The couple have set up a WeChat group for people to learn more about plogging. Currently there are more than 100 people from different parts of the country in the group to take an active part in the environmental movement. In honor of World Environment Day this year, the Industrial and Commercial Bank of China(中国工商银行)started plogging campaigns (运动)in 280 cities, attracting 13,000 people to join in.

    Plogging can be done almost anytime and anywhere, and costs almost nothing. Will you take it up?
