Online Shopping Spree Sets Record
Chinese shoppers spent billions online yesterday as they took advantage of discounts offered on Singles Day (November 11). It is a festival for young single people to celebrate by eating together, sending gifts or going shopping, thus seized on by online retailers to increase sales. It took only 13 hours for sales on just two online sites, Taobao and Tmall, to fly past last year's overall total of 19.1 billion yuan (US$3.1 billion).The final figure of Singles Day reached an astonishing 35.02 billion yuan as hundreds of thousands of consumers rushed to buy clothes, furniture, and home decoration items at discount prices. What friends and colleagues greeted each other with that day was “Bought anything today?” as they exchanged tales of bargains or disappointing news of popular items sold out minutes after the spree began at midnight. In under nine hours, turnover at the Alibaba Group's Tmall and Taobao sites had exceeded that of last year's Cyber Monday, a similar event in the United States. “We hope other e-commerce sites also did a good job as we want Singles Day to be a holiday for consumers and a good chance for retailers to discover the unmet needs of shoppers,” Jack Ma, founder and chairman of Alibaba Group, told reporters. “It's not a difficult thing to bring our total transaction size to 100 billion yuan in a couple of years but we hope to do more to help vendors and manufacturers to upgrade their products and service to reach more clients,” Ma said at a news briefing.

1. 这是一道词组辨析题。此题信息对应短文第一段第二句“……结果被网上零售商利用来增加销售”，此处关键是词组take hold of 与词组seize on同义，就是“抓住，利用”之意，所以答案是T。
2. 这是一道细节题。此题信息对应短文第二段第二句，“光棍节最终销售额达到惊人的350.2亿元”，而题目为“今年的最终销售额达到191亿元……”，信息不准确，所以答案是F。
