     A good relationship (关系) with a teacher may help you learn better. But what should you do if you

just dislike the teacher?

find the practical value in classes you don't like. You may hate math.    2    

     If you find a subject hard, talk to your teacher to be given more help.      3  

     It may help you raise your grade gradually.

can also talk to your teacher when he or she is free. Use this time to get extra help, ask questions, or talk

about your progress in class. You may be surprised to learn that your teacher is a bit more relaxed and

friendly than when lecturing in front of the whole class.

     If you don't agree with your teacher, do not quarrel with him or her.   5   Just as teachers need to

be fair and treat everyone equally, students have responsibilities too. You don't have to like your teacher

or agree with what he or she says, but it is necessary to be polite.
