A
As Labor Day is coming soon, our class is excited to share our plans for the holiday. Here are some of them.
Lin Tao decides to spend his vacation tidying up his room. By tidying up, he can put everything in order. Besides, a clean and organized room provides a comfortable environment for him to study better. More importantly, tidying up the room teaches him to take care of his own space and be responsible for his living environment.
Xu Ming expects to work on his grandpa’s farm during the vacation. He thinks it’s a great way to enjoy the fresh air, the warm sunshine, and the beauty of nature. It also gives him a chance to learn practical skills. He can learn how to plant seeds (播种) and take care of animals. By working on the farm, he will realize that every mouthful of the meal on the table results from farmers’ painstaking (辛勤的) efforts.
During the vacation, Sheng Fang plans to do something meaningful—helping her parents with housework. Her parents are really busy every day. She thinks she can help wash clothes, sweep the floor or cook meals. She likes to see the satisfied smiles on her parents’ faces, and it will make her have a deep sense of satisfaction. She thinks every family member should play a part in keeping the household running smoothly.
