I would like to keep on writing in blog

Dear Chris, first of all, I would like to thank you for looking over all of our blogs, and second, thank you for giving us the third times to redeem our grades.
I know I didn’t write enough to get the good grades at first time, but I will do my best to write enough this time. I really appreciate you to give me the opportunity to average the grades.
Actually, I think you are a good teacher. I am not fawning on you, really. Maybe we didn’t like your classes before, but in fact, I really admire your change, you have really given much thought to the class, and you are changeable and flexible, just hope we can really learn more on classes. I was so touched about this. I have some suggestions that you can take as the references, maybe you can try to walk around in front of classroom, then students would have the sense that you are teaching, so they will not fall asleep easily. In addition, maybe you can try to have conversations with students, not just talk with “computer”, and the students may feel that they participate in the class.
I hope I have not been too directly, if so, I beg your pardon. But we really like you! Because you are so kind and funny. ^^
