　　Views on college students credit card consumptions
　　Nowadays, it is becoming commonplace that many college students pay by credit card while shopping. And advanced consumptions has become a fashion among youngsters.
　　There are many pros and cons about credit card used by college students. Some people are in favor of the credit card consumptions, pointing out the fact that it is a more convenient and safe way compared with the traditional way of paying by cash, which is easy to lose and not environmentally friendly. While others argue that college students are too young to use credit card rationally. They are more likely to spend money recklessly without considering whether they have capability to return it on time. What’s worse, those who cannot control their desire to consume will end up involving in financial crisis and damaged personal credit.
　　From my point of view, though credit card indeed brings a lot of convenience to our life and changes the way of consumptions, we should always keep a sober mind and utilize it properly.

Secondhand Goods
　　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?
　　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.
　　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.
