    I have many different hobbies. I would like to share (分享) them with you. I have many different after-school activities every Monday, Tuesday, Wednesday, and Thursday and some Sunday activities.

    I am learning the Arabic Dabkah. It is a traditional Arabic folk dance. This Sunday I am going to perform in an Arabic fashion （时尚） show. The girls and I will show traditional Arabic clothes to the audience. It must be great fun! I also like ballet （芭蕾舞）. So you see, I love all kinds of dance and it is my favourite hobby. I take ballet lessons with two of my best friends every Sunday. I also love choreography （舞蹈设计） and love to dance to music with my friends. My favourite singers are Miley Cyrus, Rihanna, Avril Lavigne and the Jonas Brothers.

    One of the activities I do out of school is gymnastics （体操）. I really enjoy gymnastics because it makes me keep fit. I also enjoy playing volleyball. I am on the school volleyball team.

    If you have some hobbies like me, please share them with me!
