     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.

     A recent report from a newspaper says  about  18%  of the young students in Shanghai have mental

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

Some think they will look stupid if they go to see a doctor. Others won't talk about their secrets.
