In recent years, second-hand transactions have become quite common. Nowadays there are more and more secondhand goods in the market, such as secondhand books, furniture, appliances, cars, and so on. Why do so many people like to buy secondhand goods?

　　近几年，二手交易已经变得很普遍。现在市场上有越来越多的二手商品，比如二手书，家具，电器，汽车等等。为什么这么多人喜欢买二手商品呢？

　　The following reasons can account for this phenomenon. Above all, secondhand goods are cheaper than new ones. This enables those people who have poor financial abilities to buy the things they want. Moreover, secondhand goods transactions make it possible for people to make good use of the goods which may be useless in their hands. Besides, Internet provides a more convenient and quicker transaction platform for secondhand goods.

　　以下原因可以解释这一现象。首先，二手商品比全新的便宜。这使那些经济实力较弱的人能够买他们想要的东西。其次，二手商品交易使人们能好好利用在他们手上没有用处的东西。此外，互联网给二手商品提供了一个更方便快捷的平台。

　　However, there are also some problems in secondhand goods transactions. For one thing, the quality of secondhand goods can not be promised and you can not enjoy the good after-sale service. For another, secondhand goods market lacks enough supervision and management, and there exist many dishonest business activities. In a word, I think secondhand goods transaction is a good trading way, but it needs further perfection of the rules.

　　但是，二手商品交易也存在一些问题。一方面，二手商品的质量不能够保证，你不可以享受良好的售后服务。另一方面，二手商品市场缺乏足够的监督和管理，存在很多不诚实的商业活动。总之，我认为二手商品交易是一种好的贸易方式，但是需要进一步完善规章制度。
