1．　　Most people don't take first aid training because they are busy. Some even think only doctors need to learn first aid. But in fact, everyone should learn first aid because it is helpful. Here are the advantages of learning first aid.
　　Help to save lives
　　First aid helps you save lives. Giving someone first aid can help him or her get better soon. First aid training teaches us how to keep calm in emergencies (紧急状况).
　　Help someone feel better
　　Not every accident or injury (受伤) needs treatment (治疗) in the hospital. But it doesn't mean you should not try to help someone injured, even though the injury isn't very serious. You can use first aid to help anyone in need, for example, a patient in great pain or a child crying because of a cold.
　　Keep a situation from getting worse
　　Sometimes, if a person doesn't receive first aid in time, his or her condition will get worse immediately. If you offer him or her basic medical care, you will help him or her feel better and keep things from getting worse.

　　"You've changed your take﹣out boxes and they are more beautiful now, right?" Qian asked. "Yes, it's a special way to encourage (鼓励) customers to take their leftover home, " the worker answered.
　　Dong Xiujie, the manager of the restaurant, told people not to order too much food. The slogan "Food is a gift from nature, so let's not waste it!" can be seen everywhere in the restaurant.
　　This year food waste is serious in some places. But on the other hand, many people don't have enough food because of the bad weather and COVID﹣19.
　　President Xi Jinping told us not to waste food. To follow his call, many places took action. In Hubei Province, the Wuhan Catering Association asked people to use the"N﹣1 mode (模式)". It means that if five people eat together, ordering food for four is enough. In Xi'an, restaurants were asked to offer fewer dishes to stop waste. In Hefei, Anhui Province, more than 500 people gave out leaflets (发传单) about saving food and helping poor people who need food in China.

3．　　Early in 2020, our country was seriously affected (被影响) by COVID﹣19. When I look back to those months, I find that it was really a special experience for all of us.
　　Many students said that they got fat during the past few months. But my weight (体重) has dropped from 63 kg to 53 kg in just three months. How did I make it?On the one hand, I went on a diet (节食). What was more, I also kept a habit of skipping rope every day. Although I felt tired at first, I didn't give up. I tried my best and finally, all of my hard work paid off.
　　My hard work was shown not only in staying healthy, but also in reading. I used to only read books about animals. However, reading the same kinds of books all the time made me stubborn (顽固的) and not want to accept others' ideas. So I decided to make a change. I began to read other kinds of books. By reading different kinds of books, I found a new world and learned a lot.
　　You have to work hard to improve your life. You can always make yourself a better person.
