如下：
I am a middle school student. Although my studies are busy, my spare time life is still rich and colorful.
我是一名中学生。尽管学业繁忙，但是我的业余生活仍然丰富多彩。
I often take part in sports after school. I like playing basketball and football very much. Sports make me healthy and study better. In the evening, I often read some books.
放学后我常常参加体育活动。我非常喜欢打篮球和踢足球。体育运动令我身体健康、学习也更加优秀。到了晚上，我常常会读点书。
I think books are our best friends. They teach us a lot of knowledge that we can't learn in school, so reading greatly enriches my spare time.
我认为书籍是我们最好的朋友，它教给了我们许多在学校里学不到的知识，所以读书大大充实了我的业余时间。
Occasionally I watch TV and surf the Internet, which is a good way to relax myself. At the same time, I can broaden my horizons.
偶尔我也会看看电视、上上网，这倒是放松自己不错的方式，与此同时，还能开阔自己的视野。
On weekends, I often help my parents do housework: cleaning the house, washing clothes and learning to cook.
周末的时候，我经常帮父母做做家务：打扫房子、洗衣物、学做饭。
In winter and summer vacation, I have enough time and can do many things, such as being a volunteer to help those in need.
在寒暑假，我有足够的时间，可以做的事情有很多，比如做一名志愿者，去帮助那些需要帮助的人们。
This is a valuable experience for me. In a word, I enjoy my spare time.
这对我来说是一份宝贵的经验。总之，我乐享我的业余生活。
