Nowadays phones play more and more important part in our society.On the contrary,letter-writing became not as common as the past.So someone hold that phones will kill letter-writing in future.However,I do not agree with them.
It could not be denied that phones can make people keep in touch with each other more convenient and easily,but letter-writing still has its advantages,so it will not be killed in future.First,sending a letter is much cheaper than having a telephone call.Second,people can not only greet each other but also exchange their thoughts in letters.When a person writes,he can organize his mind and express his idea and feelings more logically and completely,but it is hard for phones to make it.Finally,people can easily keep secret in the letter and say whatever they want to say,while they sometimes can not do that in a telephone.
So from the above,we can conclude that no matter how important the phones is,letter-writing will not be killed for ever.
