【正确答案】
B
【答案解析】[听力原文] It took eight minutes for shoppers to blow a billion dollars buying items from China's largest online retail company, Alibaba. It was during Singles Day—the biggest online shopping event in the world. The BBC reports that 14 hours into the event, sales on Alibaba had climbed to $10 billion. That's more than the grand total of last year's online sales on Singles Day. To put this into perspective, the biggest online shopping day in the U.S.—Cyber Monday—only hit $2 billion in sales last year. So what is Singles Day? Alibaba started the tradition in 2009. The company is the owner of the Singles Day brand, though other retailers also have major sales, like Black Friday, all in the name of single people buying gifts for themselves. It's often described as the 'anti-Valentine's Day' and falls on 11/11. According to Forbes, it's now the most profitable online sales holiday in the world, and it's only getting bigger. And this year's Singles Day kicked off in style. Businesspeople and celebrities led a four-hour television show to celebrate the launch of the sales event. What is this news report mainly about? 新闻开头就明确了主旨，即介绍阿里巴巴的“双十一”活动，这是全世界最大的网购盛会，之后的新闻中继续介绍了“双十一”的历史、销售情况、与其他国家类似活动的比较，因此答案为选项B。
