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. 我上大學的時候，在假期到來前，我很擔憂買車票回家。我不得不站着長長的隊伍，等着到我買票。但是事情已經改變了，如今人們能夠在網上買車票，優勢是很多的。
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，人們能節省很多時間。當我去到售票窗，總是有很多人，我買到票的最快時間大約一個小時，最長的時間超過四個小時。但是如今我只需要在網絡上點擊，就會快速買到票。多麼快速啊。
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，在網上買票也比較安全。當人們來到火車站，不僅有乘客，也有排隊買票的人。到處都是人，一旦意外發生，人們不易逃走。但是在網上買票能減少人流量，讓人們在室內更加安全。
Online purchase is the trend, people can use computer to do more things. 網上交易是趨勢，人們可以用電腦來做更多的事情。
