In recent years, a new type of online shopping is rapidly gaining popularity — group purchasing, which was originally introduced from foreign countries but is now widely accepted all over China. People can buy not only goods, but also all kinds of services on group purchasing sites.
Group purchasing is very convenient, and saves people a lot of money. But it also has some problems. Since group purchasing is nothing more than another form of online shopping, the nature of it is no different from other online shopping patterns. Problems that exist in online shopping also can be found in group purchasing, like deceptive advertisements or poor after-sale services.
In my opinion, we should treat group purchasing as a way of shopping and nothing more. We must be careful not to buy something we don’t need only to follow the fashion.
How to Study Efficiently
As students, we have to study almost every day. However, not everybody knows how to study efficiently.Do you want to know better about it?
There is some relationships between the study efficiency and the hours spent in studying in a day.In fact, more hours of study do not necessarily result in better or higher study efficiency.It is said that the optimum of efficiency comes when one studies about 5 hours and the efficiency begins to drop as he studies longer than it. By the time when one studies 11 hours per day， his efficiency of study becomes very poor.
In conclusion, there is always a maximum of efficiency and an appropriate amount of time for study in a day. More time spent in study doesn’t always mean greater efficiency.
