My friends have different hobbies. Lily is 11-year-old girl. She has a beautiful voice. Singing has become her favorite hobby. She sings Karaoke and . (watch)many music videos every day and she often sings at (friend) parties. John can swim very (good). He usually swims in the river near his house. And he practices swimming in a swimming pool the morning of Sundays. He wants (be) a swimmer at Olympics one day. Many (child) are interested in flying model planes. Bobby is one of them. He thinks 53. is fun and relaxing. He flies model planes with his friends in the park every weekend. 54. now, he is busy every day because he is going to be in the (three)year of middle school. Can he still keep flying model planes as a hobby?
