I believe that letter writing will not be replaced by phones completely, and I even advocate that we should use letter writing to replace phones in some memorable situation.

With the development of people’s life standard and the progress of technology, phones have been very common in our lives. Therefore, there are some people worrying that letter writing will be replaced by phones totally. In my opinion, phones will not kill letter writing completely.

随着人们生活水平的发展和技术的进步，手机在我们的生活中是很普遍的。因此，有些人担心手机将会完全取代写信。在我看来，手机不会完全取代书信。

Many reasons can account for my views. First, compared with phones—a straight way to express feeling and to communicate, letter writing is more implicit. In other words, letter writing is an implicit way to deal with problem, especially in an embarrassing situation. For example, when we have quarrel with our friends sometimes, we can explain or apology to them by writing a letter. Second, letter writing is more sincere and formal than phones in expressing our gratitude. Most of the well-educated are inclined to use letters to express their respect and gratitude rather than other ways in that they can collect these letters to commemorate their association or affection. I believe that they will keep this habit all the time. Finally, to some extent, letter writing is much cheaper than phone calls and the former is more suitable for the poor.

许多原因可以解释我的观点。第一，手机——一种表达情感和交流的直接方式，而信函则更加的含蓄。换句话说，写信是含蓄的处理问题的一种方式，尤其是在一个尴尬的局面。例如，当我们与我们的朋友吵架的时候，我们可以给他们写一封信来解释或道歉。第二，写信比电话更真诚和正式来表达我们的感激。多数受过高等教育的人都倾向于用书信来表达他们的敬意与感激，而不是其他方式。因为他们可以收集这些信件来纪念他们的想法或情感。我相信他们会一直保持这个习惯。最后，在某种程度上，写信是比打电话便宜得多，前者更适合穷人。

Therefore, I believe that letter writing will not be replaced by phones completely, and I even advocate that we should use letter writing to replace phones in some memorable situation.  

因此，我认为写信将不会被手机完全取代，我甚至认为在一些难忘的情况下我们应该用写信来代替电话。
