    var text = "Dear Mrs.Ma,# $ $ I'm sorry to hear that you won't teach us next term.                                                                                                                         But the memory between you and us has already deepen in my mind.                                                                                                                        # $ $ In the early lessons you taught us,                                                             I thought you are a classy teacher.                                                                                                                         A few weeks later,                                         I found you are also a skillful teacher.                                                                                                                         Your teaching methods are so extraordinary that I have made a wonderful progress just less than one year.                                                                                                                                                                 It's responsible to you for correcting our writing practice homework and writing down your advice on everyone's paper.                                                                                                                                                                 Besides, you are a rich idea teacher.                                                                                                                         The punishment that let the lazy students perform in front of the whole class is excellent!                                                                                                                                             You are our friend more than our teacher.                                                                                                                         When we play a joke on your Chinese pronunciation,                                                             you'll blame us with smile.
