Hi Grace,
How's it going? Sorry I haven't emailed for a while, but I had so much to do!
I had told you about my decision to take up a sport. I knew I wasn't fit and I wanted to get some exercise. But that wasn't the only reason that I decided to do a sport. Students who play sports do better at school. 【小题1】Exercise also helps learning and memory (记忆).
【小题2】First, I tried soccer. I had played a bit of soccer before and I thought it wouldn't be too bad. I knew I couldn't nm for very long without feeling tired. On the first day, I was able to nm for the first ten minutes, but then I was so tired that I couldn't even kick the ball!
Then, I tried volleyball. 【小题3】I was able to run for the first twenty minutes and I wasn't the slowest runner in the team! After a few weeks .I could run faster and longer. I was doing better and feeling better. 【小题4】Maybe I'm not a team sport person after all!
Finally, I tried kung fu (功夫). It's a great sport that exercises the body and the mind. You learn to follow instructions carefully and do what you are asked to do. This is the right sport for me! 【小题5】I feel so confident that l even showed some moves to the class last week! Can you believe it?
I hope you're OK! Write and let me know what you've been doing!
Bye for now!
Kristie
