My Winter Vacation

Winter vacation is coming soon, and I have made a detailed plan for it. First, I will finish all my homework on time so that I can have more time for other activities. Second, I plan to read some interesting books to enrich my knowledge. Reading can not only broaden my horizons but also improve my writing skills. Besides, I will help my parents with housework, such as cleaning the room and washing the dishes. I want to learn to cook some simple dishes, too. Of course, I won't forget to take some exercise every day. Playing basketball with my friends is my favorite sport. Lastly, I am going to visit my grandparents with my family. I look forward to a wonderful and relaxing winter vacation.

希望这些建议能帮助你写出一篇优秀的寒假英语作文!
