<p>Dear Ben,</p>
<p>Thanks for your letter. It's great to hear from you. I'm sorry to hear your best friend doesn't want to do sports. I think people should do sports because it's good for their health and it's fun!</p>
<p>I really like playing basketball and swimming. In my PE lessons, we usually play volleyball or do some exercises. What about you? What do you usually do in your PE lessons and what sports do you like?</p>
<p>I have to go now. Write back soon!</p>
<p>Best wishes,</p>
<p>[Your Name]</p>
