Reading comprehension.

     Students often meet with questions as follows: bullied by someone, worried about a weak subject, puzzled

by family problems or concerned about pets at home. All the questions above may make you not concentrated

on your study. Who can you turn to if you are such an unlucky student? A great person to share your thoughts

and feelings with is your school counselor (顾问).

     Add school counselors to the list of people you can turn to when you need help. They know how to listen

and can help kids with life's challenges (挑战). Counselors have special training in how to help kids solve

problems, make decisions, and stand up for themselves. That doesn't mean your counselor will wave a magic

wand and the problem will go away. But it does mean he or she will help you cope with it. Coping is an

important word to know. Sometimes, kids and grown-ups have difficult problems. Coping means that someone

is trying to handle these problems and make things better.

     Your school counselor is available for you and wants to make your school experience the best it can be. The

counselor's job is to take your problem seriously and help you find a solution. The counselor also wants to help

you learn as much as you can in class, be a contributing member of the school community, and be a positive

influence on your environment.
