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 in the test, and when she looked at the exam papers, 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 having problems in learning and getting on well with people. Many students who have problems won’t go 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.

Laughter and tears are part of living. But do you find enough time for laughter? I am not
asking if you experience lots of good times. Of course we should laugh during the happy times.
1  
Erma Bombeck is known for her humorous books, but she wrote one that covered a more
serious topic: cancer in children. Erma talks with lots of children with cancer and learns an important life lesson from them.   2  
She tells the experience of 15-year-old Jessica from Burlington, VT. Jessica’s leg was amputated (锯掉) at the knee because of cancer. Jessica tells about playing soccer. She kicked the ball hard and it flew off in one direction while her artificial leg flew another way. Then “the tall, pretty person that I am,” she said, “sat on the floor in laughter.”
Jessica may not have laughed about her cancer, but she laughed about dealing with its results.  3  
Then there is the story of 17-year-old Betsy. She made her way to the radiation room(放射室) for
her regular radiation therapy. As usual, she dropped her hospital coat and, wearing only her birthday suit, climbed onto the table and waited. After a couple of moments she began to realize something disturbing: the extra people in the room were not the medical students she had thought, but rather painters giving an estimate on painting!    4  And like Jessica, her ability to laugh helped her to deal with one of the most difficult things a young person can endure(忍受) — cancer.
There is a time to weep and a time to laugh.    5   And you’ll smile at the end.
