填空题

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 exercises. 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 .

小题2:   First, I tried soccer. I had played a bit of soccer before and I thought it would be too bad. I knew I couldn’t run very long without feeling tired. On the first day, I was able to run 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 . It’s a great sport that exercise 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 I even showed some moves to the class last week. Can you believe it?

I hope you are OK! Write and let me know what you’ve been doing!

Bye for now!
