Now I’d like to introduce our English paper to you. On my opinion, the paper is very imptance to our study and daily life. We can improve our English, especially writing English by reading it and writing. At the same time, it’s a fun and relaxing to read it, it makes our after-class time meaningful and colorful. There is a lot of columns in our paper, such as School News, Teachers’Advice and Students’Voice.Not only it make us learn the important events of our school, but helps ourselves communicate with teachers. However, we can take the advices from our teachers more seriously. In a word, I like our paper very much.
