随着互联网的发展，二手市场为人们提供了交换二手商品的一个机会正在日益繁荣。就我而言，二手商品可以认为是一种经济行为。
There are some advantages of consuming second-hand goods. In the first place, we can use less money to buy some high-quality goods and that can ease the burden of finance, especially for the newly established home of the youngster. Second, it is a kind of cyclic utilization and it is a friendly-environmental action. For example, the exchange of second-hand furniture can reduce the number of trees of being cut down. Finally, second-hand consumption indicates a change in people’s awareness. People’s accepting of second-hand goods suggests that they change their opinion of consumption from extravagance to frugality, which is a good for our environmental protection. 
二手商品交易有一些优点。首先，我们可以用更少的钱去买一些高质量的商品，这可以减轻经济负担，特别是对那些新成立的家庭的年轻人。第二，这算是循环利用的一种了，也属于营造友好环境的行动。例如，二手家具的交换可以减少砍伐的树木的数量。最后，二手商品消费表示人们的观念有所改变。人们接受二手产品意味着他们的观念从奢侈浪费到勤俭节俭的转移，这有助于我们保护环境。
In a word, second-hands have many advantages and we should make full use of them. In addition, I hope that our government should enhance supervise towards second-hand market to reduce risk of consuming second-hand goods.  
总之，二手商品有很多的优点，我们应该充分利用他们。另外，我希望我们的政府应该加强对二手市场的监督，减少其风险。
