Since the invention of computer, the world has come to the information stage. Today, people can do almost all the things through the Internet. They work and shop and communicate by this convenient way. As the information can be received from all kinds of resources, some people choose to search the Internet to get the diagnose before they go to see the doctor. If the doctor tell them something that is different from what they see from the Internet, then they will question about the diagnose. Online medical service indeed helps people to get the idea of their sickness, but it can’t be trustworthy, because who knows whether the information is given by a professional doctor. What’s more, the accurate diagnose should be checked the body, while online diagnose can’t offer this service, so it is unreliable.自从电脑发明以来,世界已经来到了信息阶段。今天,人们通过互联网几乎可以做所有的事情。他们工作，购物和交流方便都通过这种方式。网上可以收集到到各种各样渠道的信息,有些人选择在网络上搜索信息诊断才去看医生。如果医生告诉他们不同于他们从互联网上看到的信息，然后他们就会质疑医生的诊断。在线医疗服务确实能帮助人们得到一些关于他们的疾病想法,但是不值得信赖,因为谁知道这些信息是不是由一个专业的医生提供的。更重要的是,准确的诊断应该检查身体,然而网上诊断无法提供这个服务,所以它是不可靠的。

No matter in the old days or in present modernized society, postal service always plays an important role in our life. In the past, it is the main bridge connecting with people. We all know that the communication field in the past is not well-developed. If people wants to communicate with someone does not live around them, sending letters is the most popular way. As the limitation at that time, sending letters is the most convenient way. Nowadays, although people have so many choices to connect others and send packages, postal service is very considerate relatively. For example, there so many logistics companies, but only postal service willing to go to the country. Without it, our life will be affected. It is clear that postal service is significant in our life.
不管是过去还是现在的现代社会，邮政一直在我们生活中扮演着很重要的角色。在过去邮政是人与人之间联系的主要桥梁。我们都知道以前通信领域并不是很发达。如果人们想要和不跟他们生活在周围的人沟通，寄信是最流行的方式。由于当时的局限性，信件是最方便的方式。如今，虽然人们有很多的选择可以与他人沟通、寄送包裹，但是相对来说邮政的服务是很周到的。例如，有那么多的物流公司，却只有邮政愿意到达乡村。没有邮政，我们的生活将会受到影响。可见邮政在我们的生活中是很重要的。
