When I was about twelve,I suddenly developed a great passion

When I was about twelve,I suddenly developed a great passion for writing poetry.I 21 all my other hobbies,such as collecting stamps,and spent all my spare time reading poetry and writing it.This habit of writing poetry 22 every possible occasion soon got me into trouble at school.23 a lesson did not interest me,I would take out my notebook and start writing poems in class.Of course I did this very cautiously,but it was not long 24 I got caught.One day while I was busy writing a poem during a geography lesson,I looked up to find the teacher standing over me,fuming with anger 25 I was not paying attention.He tore the poem up,with a warning 26 time in his class.All the same I was convinced that I had written a good poem,so that evening I wrote it out again 27 memory.Not long 28,I read about a poetry contest and I decided to send in my poem.Weeks later,long after I had given up hope,I got a letter 29 me I had won the first prize.Everyone at school was very impressed --- except the geography teacher,who watched me more carefully than ever.He was quite 30 that I was not going to write poetry in his lesson!
