C
Teenage life is not just about studying textbooks. Many students today spend all their free
time on homework, but after-school activities play an important role in their growth. A small survey of 500 high school students from three local schools shows that 65% of those who join after-school clubs feel less stressed than those who only study. One student in the survey said, “Club meetings help me forget about exam stress for a while—I feel more relaxed afterward.”
Why do some teens avoid after-school activities One main reason is fear of falling behind
in lessons. They think extra time should go to homework or exam practice. Some teens also worry about not being good enough—for example, they might hesitate to join a sports team because they think they’re not fast enough. Another reason is not knowing how to choose—there are so many options like sports teams, art groups or reading clubs.
In fact, after-school activities bring great benefits. Sports like basketball or running help
teens stay healthy and learn teamwork. Last term, a group of students in the art club organized a small exhibition at school. Their paintings about daily life got lots of praise, and many said they felt proud for the first time. Art clubs, such as painting or music, let them show creativity. Even reading clubs can improve vocabulary and make teens more confident when talking to others. These skills are just as useful as good grades for future life.
