阅读下面文章，回答18~22题。

　　①在美国的一次家庭宴会上，我看到一位老人戴着一个非常美丽别致的项圈，那上面有11块宝石，颜色形状各不相同，但看得出，每块都很名贵，在灯光下发出彩色的光芒。你在看到她的那一刹那，必会注意到她的项圈，因为她的表情和所有体态，都像指针一样指向了她的项圈。如果你注意不到她的项圈，你简直就是一个瞎子；如果你注意到了她的项圈，而不过问这件事，那你简直就是对她的大不敬了。

　　②在这种压力之下，每个人在寒暄之后，都要夸奖她的项圈，她就如愿以偿了，情绪高昂地说着什么。轮到我与她见面，我的谈话也从项圈开始：“这是我看到过的最美丽最别致的项圈之一。”

　　③这可并不全都是客套。那项圈的确是独一无二的，晶莹璀璨。

　　④“谢谢！它的确是独一无二的。是我把毕生积攒的名贵宝石都拿了出来，我自己设计了这个样式交给工匠制作，无论从价值还是款式来说，它都极为名贵别致。而且，对我来说，它的价值更是难以估量的，因为这只项圈有很大的象征意义。”老奶奶说。她说话的时候，鹤发鸡皮的脑袋摇个不停，脖子上的项圈跟宝石相撞，精光四射，仿佛一串电焊的火花。

　　⑤说到这份儿上，脖子晃成了这个样子，出于礼貌，你就是再没兴趣，也得问老人家这个项圈的象征意义是什么。

　　⑥【甲】就像一个好猎人下了套子，看到你的爪子果不其然地被她绊住了，老奶奶的兴奋溢于言表。她说：“我这11块宝石，代表我的11个孙子和孙女。蓝色和绿色的宝石，代表的是男孩；粉红色和橙黄色的宝石，代表的是女孩。现在，你已知道了这个秘密，你仔细地数一数，我有几个孙女几个孙子？”

　　⑦我很仔细地数过了，但老奶奶究竟有几个孙女几个孙子，又忘记了。记住的只是她那张充满期待的脸和筋络缠绕的脖子。【乙】项圈是美丽的，但如此近距离地观看，这苍老的面庞，在晶莹剔透的宝石的映照下，有一种残酷的枯萎。

　　⑧也许是太想让老奶奶高兴了，这时，我千不该万不该，问了一句话：“您的这11位孙女孙子常常来看您吧？”

　　⑨老奶奶的脸色黯淡下来，喃喃地说：“是咧，他们来过。可是，已经很久不来了……”

　　⑩整个晚上，我都为自己的贸然发问后悔不已。⑩不，直到今天，我都为自己的贸然发问后悔不已。

　　不，直到今天，我都为自己的贸然发问后悔不 已。我为什么要自作聪明地用手指捅一位老人期待和自豪的泡沫？

　　有时，我看到大街上的女孩戴着灿烂的宝石项圈，会不由自主地想，天底下，无论东方还是西方．无论中国还是美国，有没有这样一个女孩，在盛大的宴会上，骄傲地指着自己项圈上的宝石对来宾说：这块蓝色的宝石，是纪念我的祖父，这块红色的宝石，是纪念我的祖母。他们永远在我心中。

High-quality customer service is preached（宣扬）by many, but actually keeping customers happy is easier said than done.

Shoppers seldom complain to the manager or owner of a retail store（零售店）, but instead will warn their friends, relatives, co-workers, strangers and anyone who will listen. Store managers are often the last to hear complaints. “Storytelling hurts retailers(零售商) and entertains consumers,” said Paula Courtney, President of the Verde group. “The store loses the customer, but the shopper must also find a replacement.”

The most common complaints include filled parking lots, cluttered（塞满了的）shelves, overloaded racks, out-of-stock items, long check-out lines, and rude sales people.

During peak shopping hours, some retailers solved the parking problems by getting moonlighting(业余兼职的) local police to work as parking attendants to direct customers to empty parking spaces. Retailers can relieve the headaches by redesigning store display, pre-stocking sales items, hiring speedy and experienced cashiers, and having sales representatives on hand to answer questions. Most importantly, sales people should be skillful and polite with angry customers.

“Retailers who’re enthusiastic and friendly are more likely to smooth over issues than those who aren't so friendly.” said Professor Stephen Hoch. “Maybe something as a greeter at the store entrance would help.”

Customers can also improve future shopping experiences by filling complaints to the retailer, instead of complaining to the rest of the world. Retailers are hard-pressed to improve when they have no idea what is wrong.

小题1:Why are store managers often the last to hear complaints?

A．Most shoppers won’t complain even if they have had unhappy experiences.

D．Shoppers would rather tell their unhappy experiences to people around them.小题2:What does Paula Courtney imply by saying the underlined sentence in paragraph 2?

A．The same products can be bought in other retail stores.

B．It is not likely the shopper can find the same products in other stores.

C．New customers are sure to replace old ones.

D．Not complaining to the manager causes the shopper some trouble too.小题3:What contributes most to smoothing over issues with customers?

A．Hiring of efficient employees.

B．Manners of the salespeople.

C．Huge supply of goods for sale.

D．Design of the store display.小题4:To achieve better shopping experiences, customers are advised to ______.
