　　第8期How to Write参考范文

　　With the development of communication, many teachers often talk with parents via the social software.

　　Firstly, some teachers think it necessary to inform the parents of their children’s situations at school, such as the examination performances and classroom behaviors. Secondly, they think it is parents’ responsibility to work with teachers to help the children correct their mistakes. Only if the parents know how their children perform at school can they help their children to make progress.

　　In my opinion, it’s necessary for teachers to keep the parents informed. And it is a good idea for them to keep in touch with parents via the social software, which is easy and timely.
