     Mr. Ma, a famous mental doctor (心理医生) from  Beijing once said at an important meeting, "Now
many young students can have problems with their minds. Some  students become worried because they
have to study very hard. Others have trouble getting on well with  people  around  them like their parents
and classmates. Parents and teachers should care more about this problem."
     Then Mr. Ma gave   some examples.  A  middle  school   studen t from  Xi'an   was doing badly in his
lessons. He thought his teachers and friends often laughed at him, and he became so nervous and worried
that one night he left his home without telling  his  parents. Another student, a 14-year-old schoolgirl from
Shanghai, was very afraid of exams. While she was reading the exam paper, she couldn't think of anything
to write.

problems. They often feel worried and very unhappy. Unluckily many of them won't go and ask for help.

     At the end of the meeting, Mr. Ma gave some good ideas to young people:
Talk to your parents or teacher often.
