　　六、閱讀下列短文，從 A 、 B 、 C 、 D 四個(gè)選項(xiàng)中選出一個(gè)最佳答案。 ( 每小題 1 分，共 10 分 )
　　The year 2000 has been tough for online retailers. Changes in the market have driven many sites out of business, and many others are only barely surviving. The holidays, promising GREatly increased sales, offer hope for many e-commerce sites. The good news for retailers is that the holiday market will grow; this year's holiday sales are predicted to be 66% higher than last year's.
　　In a year when over half the U.S. population has access to the Internet, e-commerce sites can expect dramatic increases in site traffic before the holidays. Forrester Research predicts $10 billion in holiday revenues, and Jupiter forecasts the U.S. holiday market as $12 billion. Gartner Group predicts $10.7 billion in North American holiday sales and worldwide sales of $19.5 billion.
　　While revenue estimates vary, it's clear that Holiday 2000 will be big for e-commerce. Customers will shop online this holiday season for convenience; by shopping online, customers avoid crowds, transportation hassles, and inconvenient store hours. One customer commented in our tests that she would shop online “ to avoid the hassle of going to different stores. ”

　　Despite the eager shoppers and the predictions of a big holiday season, there is bad news for online retailers: the e-commerce industry is losing billions of dollars in potential sales. Shoppers want to purchase online, but many sites make it too hard to buy.
　　To gain the most from the holiday season, sites must pursue a simple strategy: improve the customer experience. Improving the customer experience can yield an additional $8 billion in North American sales, and $14 billion in worldwide online sales this holiday season.
　　According to Gartner Group projections, worldwide online revenues for the holiday season will be $19.5 billion.
　　In our consumer tests of major sites across key holiday categories, we found that 43% of buying attempts failed. These findings suggest that the $19.5 billion represent only 57% of potential sales this holiday season.
　　Lost sales due to poor customer experience thus total more than $14 billion: · $34.2 billion － $19.5 billion=$14.7 billion.
　　It is worth noting that our $14 billion does not include future losses due to poor experience this holiday season. Millions of consumers will shop online for the first time this holiday season. If they have a good experience, they are likely to continue shopping on their favorite sites in the future. If they have a bad experience, they will likely never return to the sites where they were unable to buy(if indeed they return to shop online at all).The actual losses due to poor customer experience may thus be significantly higher than our $14 billion estimate.
　　In our tests, problems with the checkout process were the greatest cause of failed purchase attempts. More than 40% of failures were due to difficulty with checkout. Customers had found a product they wanted, added it to their cart and decided to place an order. They were ready to buy and wanted to pay. Unfortunately, the checkout process was too difficult and made it impossible for them to buy.
　　There were several different types of problems that arose in the checkout process.The most important lesson is that poor checkout experience will cost the industry billions in holiday sales.
