Dear headmaster,
I’m writing to persude you to let us surf the internet in the classroom , we know you’re afraid that we may be exposed to unhealthy websites, actually every coin has two sides, we still think that surfing the internet can bring us more advantages.
First of all, I think it would be better if we could surf the internet, because there is a wide range of learning resources on the internet, we should make good use of it ; Furthermore, we can broaden our horizons by reading various news onlines.Last but not least , as high school students, we are building up our sense of judgement. Given chances, we are sure that we will learn how to stay away from unhealthy websites.
I do hope you can take my suggestions into consideration and make a final decision.
Looking forward to your reply.
Yours
