Dear James,
How are you going? I miss you very much. I'm writing to you to talk about the uncivilized words used on Internet. With the development of economy, more and more people become addicted to the Internet and like chatting online. As a result, lots of uncivilized words come into being, which can do harm to our society. On one hand, they damage the environment of Internet civilization. On the other hand, they influence teenagers' physical and mental health, which will have a bad effect on their development. We should do something to stop using them.
Firstly, as high school students, it's our duty to avoid getting involved in the use of uncivilized words. Secondly. we should call for our classmates and friends to keep away from them and say some kind words. Last but not least, we should report this problem to the government and ask for some help. Let’s work together to create a peaceful and civilized network atmosphere.
Yours.
Li Hua
