题型:单项选择题

Americans are buying more products and services than ever before through the Internet, and the popularity of online sales is likely to spread to other countries. Online sales now represent as much as one-tenth of all retail(零售) sales in the United States,which has led traditional stores to seek new ways to keep their customers loyal.

Lynne Shaner used the Internet to buy everything she needed for her wedding and holiday gifts for her husband. Other than food, 90 percent of her purchases(购买的东西) were made on her home computer. “I find that, by being able to go online and opt for the things that I need to select and have them delivered to me right at my doorstep, I’m free from all the driving, all the crowds, all the noise, and I usually get a better selection.”

There are a lot of people like her. Experts say American online shopping hit records in both November and December. Fifty-seven percent of Americans have bought something electronically. Store owners worry that this growing amount of online sales will hurt their business. Cornell University marketing professor Ed McLaughlin says, “They should be worried. Anything that can move online will be sold online. And it's just a matter of time. However, traditional stores can keep their customers by selling goods like clothing, which buyers may want to see and try on before purchasing. The stores could also offer things that are difficult to ship. ”

Bill Martin, whose business helps stores learn about their customers, says, “Traditional stores offer a social experience that some people enjoy. There is still a lot of emotion in the buying decision that takes place, and you can't always get that on-line. It's a rather cold process. Traditional stores can provide goods for buyers more quickly than online stores. And some retailers are using websites to persuade people to visit their stores. ”

While online shopping worries some business owners, the only worry for delivery services like FedEx and UPS is keeping up with the number of packages. UPS Manager Dana Kline says her company is very busy at this time of year. UPS is so busy that it has filled 55,000 temporary worker positions during the holiday season.
