Some students have lots of worries and feel unhappy because they have problems in learning and getting on with people like their parents and classmates. Here are two students talking about their problems.
Chen Han, 14- year- old girl
I am very afraid of the exams. I always study the hardest in my class, but I can't get good grades. I can't think of anything when I am having an exam. And before exams, I can't sleep well for days.
Su Ning, 15- year- old boy
I do well in my studies. However, I hardly have friends. Because I'm from a poor family, I don't have enough money to buy expensive shoes and my classmates laugh at me. I always feel sad.
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. How to help these students? Mr. Ma, an expert from Beijing has the following suggestions(建议) for students:
☆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.
