在學習、工作、生活中，大家都寫過作文吧，作文一定要做到主題集中，圍繞同一主題作深入闡述，切忌東拉西扯，主題渙散甚至無主題。那要怎麼寫好作文呢？以下是小編整理的四級作文：Group Purchasing_團購，僅供參考，大家一起來看看吧。
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.
