It was our English teacher's birthday yesterday. Though English is a hard subject, but I like my English teacher lot, and so do my  classmates. She is nice to us and always tells us stories of the days when she was in her twenty.  Sometimes she even stayed in school to help students make up their lessons. She always encourages us and tells us do our best. We are gratefully to her, so that day we bought him a cake and a gift. We even make a big card for her, on it we wrote all our names. Seeing these, she was moving and had a big smile in her face.去掉but
