How's it going? I'm sorry to hear that ____________________________________
How's it going? I'm sorry to hear that you got injured while playing basketball. You should have a good rest at home. And you'd better take care of yourself when you do sports.
Everything goes well here! I enjoy great changes in my school. On the one hand, the teachers make their teaching styles colorful. In my science class, my teacher always encourages us to think, and cultivates our ability to study independently. On the other hand, we have plenty of time to try what we want to do. We had our School Day last week. There are different kinds of activities, such as speech contest, talent show, volunteering.... I took part in the English speech contest, and I won the first prize. I will send you some photos about my School Day if you like.
Hope you'll get better, and be back to your school as soon as possible.
