I have many hobbies.Such as,listening to music,playing the violin.I used to listen to music when I did my homework.I like all music,but the most favoratite music is the classical music.It makes me relaxed.But,now I like collecting stones very much,I think it's very interesting.And I used to play the violin in my spare time.I think it can make me happy.Also,I love keeping pets now.I have a dog,it is very cute and clever.
I feel my life is quite happy and wonderful.
我不知道你为什么全要用过去式.难道是你过去的兴趣爱好是这些,现在没有了吗?不要说at past,i had many hobbies.感觉你现在没有很多Hobbies了.一般such as只列举一个.你列举了两个,不要再说and so on.
