2017年英语四级翻译考试模拟题:网购趋势

　　请将下面这段话翻译成英文：

　　波士顿咨询公司最近做的一项研究显示，到2020年中国将会有2.2亿家庭收入在2万到100万美元的富裕消费者。这些消费者中75%住在“较小城市”。随着网络的发展，较小城市的消费者的一种必然趋势是他们更加依赖社交网络服务上的信息。很多网络顾客都是通过微信、微博和QQ空间分组的。据估计今年中国将会有2.5亿消费者进行网购，位于四线城市的消费者平均每人会花费他们50%或者更高的工资在网购上，这一数据要比一线城市的消费者的花费高。

　　参考翻译:

　　A recent study conducted by the Boston Consulting Group says there will be 220 million affluent consumers, who are from households earning between $ 20,000 to $ 1 million, in China by 2020, and 75 percent of them will live in “smaller” cities. With the development of the Internet, an inevitable trend among these consumers is they are much more dependent on information from social networking services. Many of the website’s customers are “grouped” by Wechat, Weibo and QQ Zones. It is now estimated that 250 million Chinese consumers will shop online this year and the average shopper in a fourth-tier city in China will spend 50 percent or more of their income on e-commerce than those in top-tier cities.
