“叔叔来信了!”我高兴地喊道。可这封来信与以往叔叔寄来的信不同。这是一封电子邮件!很久以前叔叔就到美国去了。他非常关心我的学习情况，因此经常写信给我。但是他的信要经过很长时间才能到。几年以后，我们家装了电话，这样我们交流起来就方便多了，可费用也升上去了。现在好了，我们都买了电脑并且可以上因特网。这样我们可以随时交谈，而且花费并不多。世界真是越变越好了。
"Here comes uncles letter!" I shouted happily. But this letter was different from those he sent to me before. It was an email! My uncle went to the United States long ago. But he cared about my study and life very much. So he wrote me often. But it would take a long time for his letter to arrive. Several years later, my family set up a telephone set, It became easier for us to communicate, but we cost more money by calling each other. Now we both had a computer and could get on the Intemet. Then we could talk to each other any time we wanted to, and it wouldn't cost much.The world is changing, and it is changing better and better.
