Dear class,
Good morning! Now let me report the discussion in our group.
Wu Jun likes collecting stamps. Jia Mei is interested in traveling very much. Wang Peng is fond of listening to the music. And I enjoy reading books and swimming.
I think these hobbies are good for our health and life. They can make us happy. They can also help us relax after daily work and study. When we are ill, hobbies can help us get well soon.
That’s all. Thank you for listening.
