Starting a new school term is always exciting. It is a chance to see all of your friends again. But most exciting of all, the new term is an opportunity to take up new hobbies. As you know, it is common in Britain for students to take up new hobbies after the Christmas holidays. Promising to begin something new is a common New Year resolution for many school teenagers.

Most schools offer different kinds of hobby classes. Students take them in their free periods or after school. Some classes you have to pay for and others are free of charge. For example, I once took a free Wednesday evening gymnastics class that my school offered. But when I learnt how to play the drum my parents had to pay for the lesson, and they did so, like most parents, without any complaint.

The most popular extra classes at my school were piano lessons and drama club:  Both classes offered exams students could take. Because the extra classes may take up much time of the students, students with many hobbies sometimes felt more stressed than those without any. But they could enjoy their life better than those who didn't foster (培养) any hobbies at school. For example, they could build up good friendship with the persons who shared the common interest with them. Most important of all, the students with hobbies left school with many extra skills.

Frankly speaking, I haven't continued any of the hobbies I began at school. But I have never regretted taking them. After all, my best friend today is someone whom I met in my gymnastics class. The reason why we are still keeping in close touch with each other is that we have much in common.
