A recent report from Dazhou Daily says about 18% of Dazhou teenagers can have problems with their minds（内心，精神）. Some students become worried because they have to study very hard. Others have trouble getting on well with people like their parents and classmates.
Zhang Qiang, a Junior 2 student from Dazhou, could not understand his teachers in class and was doing badly in his lessons. He was afraid of exams. When he looked at the exam paper, he couldn’t think of anything to write.
Another student, a 15-year-old girl called Wu Yan from Guang’an often argued with her classmates even her parents because of some different ideas. She became so annoyed about them that she started to cut her finger with a knife.
However, many students who have problems won’t go for advice or help. Some think they will look stupid（愚蠢的） if they go to see a doctor. Others don’t want to talk about their secrets. In order to solve the teenagers’ problems, here is some advice :
●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.
