But things have changed, now people can buy the train ticket online, the advantages are various. 我上大学的时候，在假期到来前，我很担忧买车票回家。我不得不站着长长的队伍，等着到我买票。但是事情已经改变了，如今人们能够在网上买车票，优势是很多的。

When I went to the ticket window, there were always a lot of people, the fastest time for me to get the ticket was about an hour and the longest time was more than four hours. But now I just need to click on the Internet, I will buy the ticket quickly. How fast it is. 一方面，人们能节省很多时间。当我去到售票窗，总是有很多人，我买到票的最快时间大约一个小时，最长的时间超过四个小时。但是如今我只需要在网络上点击，就会快速买到票。多么快速啊。
On the other hand, buying ticket online is much safer. When people come to the train station, there are not only the passengers, but also the people who wait for the ticket. There are full of people, once the accident happens, it is not easy for people to run away. But buying tickets online can reduce the people and make them safe indoor. 另一方面，在网上买票也比较安全。当人们来到火车站，不仅有乘客，也有排队买票的人。到处都是人，一旦意外发生，人们不易逃走。但是在网上买票能减少人流量，让人们在室内更加安全。
