A hobby is something you enjoy doing when you're free.     ①     . Western people like to try exciting new things. They like to go on adventures（冒险）and often do something physically  challenging（体力挑战）.     ②     . They usually do something like handwriting or painting for fun.

Hobbies can bring us great joy as well as a lot of knowledge.     ③     . Making things can develop our imagination（想象力）and creation （创造力）. Sports can help us stay healthy. Hobbies are fun.     ④     . Sometimes we have to spend a lot of time studying

for our hobbies. But I think that if you really enjoy doing something, you should never give up. And then you will have a lot of fun with your hobby.
