Here's a short story:

Young people 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 like their parents and classmates. Liu Wei,a junior 2 student from Hefei,could not understand his teacher and was doing badly in his lessons.He became so worried about it that he started to cut his finger with a knife. Another student,14-year-old Yan Fang from Guangzhou,was afraid of exams.She got very worried when she looked at the exam paper.She couldn't think of anything to write. A recent report from Jiefang Daily says about 18% of Shanghai teenagers have mental problems.Their troubles include being worried and very unhappy.And they have problems in learning and getting on with people.Many students who have problems won't ask others for advice or help.Some think they will look stupid if they go to see a doctor.Others don't want to talk about their secret. Liang Yuezhu,an expert on teenagers from Beijing Anding Hospital has the following advice for teenagers: * Talk to your parents or teachers often * Take part in group activities and play sports * Go to see a doctor if you feel unhappy or unwell (End of story)
