英语作文《My Winter Vacation》
My winter vacation
Winter vacation is coming, so I have a winter vacation plan now. I am going to spend lots of time of my vacation on sports this year. Playing basketball is always my favourite, so some of my classmates and I will form a small team and play basketball together. Sometimes we will have a match against some other teams. I will enjoy the sense when we win the game. Of course, I will spend lots of time on doing my homework. It’s important for me to do my lessons well. If I still have enough time, I am going to visit Beijing City, and visiting Beijing is my dream from childhood to now. Oh, what a great vacation!
