When I was in college, before the holiday came, I was so worried about buying the train ticket for home. I had to stand in the long line to wait for my turn to buy the ticket. But things have changed, now people can buy the train ticket online, the advantages are various.
上大学时，还没放假，我就为买回家的火车票发愁。我不得不排着长队等待买票。但现在不同了，人们可以在网上购买火车票，好处多多。

One the one hand, people can save a lot of time. 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，人们可以节省很多时间。以前我去售票窗口买票时，总是人山人海，最快也要一个小时，最慢也要四个多小时。而现在，我只要在网上轻轻一点，就能很快买到票。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，网上购票更加安全。当人们来到火车站时，不仅有乘客，还有等票的人。人山人海，一旦发生意外，想跑都不容易。但网上购票可以减少人流，让人们在室内也能安全购票。

Online purchase is the trend, people can use computer to do more things.
网上购票是大势所趋，人们可以用电脑做更多的事情。
