Dear Miss Yan:
We all love a new teacher who has been such a breath of fresh air. Here are my suggestions for a passionate teacher who deserves like yourself. Firstly, you might not notice, but If you could slow down when you speak, it would be of great help for us to understand what we learn better. Do you know that homework is given to us from every other course everyday? So if you could reduce your homework for us, and at the same time be more playful at teaching, I sure it is not only our lives that you are making so much happier but yours as well!
Thank you for all your hard work. I look forward to your new teaching style.
Best Regards,
