读写任务。

阅读下面短文,然后按要求写一篇150词左右的英语短文。

     Nowadays, a brand new way of shopping is attracting increasing customers: online group buying, also

known as collective buying, which offers products and services at reduced prices on the condition that a

minimum number of buyers would make the purchase. Origins of group buying can be traced to China

where group buying or team buying was executed to get discount prices when a large group of people

were willing to buy the same item

     China group buying transaction volume hit US$ 1.74 billion (RMB 11 billion) in 2011, up 550% from

the same period in 2010, according to a report by Tuan800.com <http://Tuan800.com>, the

Beijing-based daily deal sites aggregator. The report also shows that 2011 was the year that the Chinese

Group-buying market got more and more concentrated with more and more Chinese ,most of whom are

white collars,teenagers and college students enjoying the benefits of group buying. And, among the most

favorable buying categories are restaurant,movie and hotel booking for travelling.

    Through group buying, on one hand, customers get a lower price than normal. On the other hand,

businessmen also cut down expenses on marketing. That is the reason why group buying websites spring

up like mushrooms in recent months. What is the most attractive in group buying must be the unbelievable discounts. Facing the discounts, customers always couldn’t resist the impulse to buy the products, even

though they do not need them.
