Echo, my favorite teacher, is a pretty and slim lady．When she talks to us, she always has a smile on his face．I think Echo is gifted teacher because she has a lot of good teach methods．Her classes are so full of funs that you will never feel bored．To improve our grades, she usually gave us some advice on how to learn English well ．What’s more, she spends much her time helping her students instead of staying with her family．Sometimes, she hardly has any time to have the lunch．Whenever I ask her questions, she will spare no effort to make me understood, with patience or care．I have never seen so a good teacher as her before．
