Dear Editor,

     I'm a Senior 1 student in a middle school. This term, my favourite teacher, Miss Mao, no longer teaches

us. I want to see her, but I'm afraid that she no longer likes me and I don't want to trouble her. I really miss

her. What should I do? 

                                                                                                                                             Tian Yan

Dear Tian Yan,

     It's bad luck that you have lost your favourite teacher. But, if she is still in your school, nothing can stop

you going to see her. When she isn't busy, ask her if she minds having a quick chat. You can then tell her

she was your favourite teacher. Everyone is happy to know they are liked!

     If she has left the school, it will be more difficult to meet her. It will be hard, but remember people always

come and go in our lives. We can't rely on (依靠) them being with us all the time.

     You may be sad to say goodbye to her, but we can remember and learn from her. Think of her best

qualities. 

     You could also try looking for similar qualities in your other teachers. Study hard and give your new

teacher a chance. In time, you might start to see that he or she has different qualities to learn from.

      Finally, you can not completely rely on other people getting you through your studies, or even your life.
