Wang’s little big ideas

Showcase for talent

Susan Boyle, you better watch out.Semifinal day on China’s Got Talent is fast approaching and these contestants(竞争者) just might push you off your pedestal (宝座).Like them or hate them, there’s no denying the contestants are causing something of a stir across the country.The performers singled out on this page will certainly offer a show about which you’ll have something to say.

C.

Top of the crops

You might think Fashion Week is about dresses rather than hairstyles.But you’d be wrong.Whether the models are in New York, London or Milan, who’s sporting the prettiest, trendiest or most shocking hairstyle is as hot a topic as the clothes on the catwalk.Despite the many hair highlights of the 2010 Fashion Week, we’ve managed to comb through the masses of material to pick a few of our favorites here.

D.

Movie messes with your head

Driving home from a screening of Inception, my husband said to me: “I don’t know how you are going to write about this movie.” “What, you mean without giving anything away?” I asked.“No,” he said.“I don’t know how you are going to explain what it’s about.” The film, by writer-director Christopher Nolan, is a gorgeous(极好的), technically perfect symphony(交响曲) of images and ideas.

(E)

Woods to split

The marriage between the golf star and his wife is officially over.Official divorce papers state that “the marriage between the parties is irretrievably broken”, thus bringing to an end the couple’s six-year marriage.Woods and Nordgren have lived apart since Woods’ November 2009 car crash, which was followed by Woods’ public admission of a series of affairs with other women.

(F)

Flowers set to bloom

What exactly does it take for a young woman to be considered a “campus flower?” Some say beauty is in the eye of the beholder, but surely there must be certain essential criteria.Perhaps we can get some answers by taking a closer look inside the training camp of the Universiade Star in Shenzhen, a competition organized to select the guides, waiters, torchbearers and flag bearers for the 2011 games.

     Would you like to be a king or queen? To have people waiting on you hand and foot? Many

Americans experience this royal treatment every day. How? By being customers. The American

idea of customer service is to make each customer the center of attention. Need proof? Just listen

to the commercials. Most of them sound like the McDonald's ad, "We do it all for you." Actually,

not all stores in America roll out the red carpet for their customers. But wherever you go, good

customer service means making customers feel special.

     People going shopping in America can expect to be treated with respect from the very beginning.

Most places don't have a "furniture street" or a "computer road" which allow you to compare prices

easily. Instead, people often "let their fingers do the walking" through the store hot lines. From the first

"hello", customers receive a satisfying response to their questions. This initial contact can help them

decide where to shop.

     When customers get to the store, they are treated as honored guests. Customers don't usually find

store clerks sitting around watching TV or playing cards. Instead, the clerks greet them warmly and

offer to help them find what they want. In most stores, the clear signs that label each department make

shopping an easy job. Customers usually don't have to ask how much items cost, since prices are clearly

marked. And unless they're at a flea market or a yard sale, they don't bother trying to bargain.

     When customers are ready to check out, they find the nearest and shortest checkout lane. But as

Murphy's Law would have it, whichever lane they get in, all the other lanes will move faster. Good stores

open new checkout lanes when the lanes get too long. Some even offer express lanes for customers with

10 items or less. After they pay for their purchases, customers receive a smile and a warm "thank you"

from the clerk. Many stores even allow customers to take their shopping carts out to the parking lot.

That way, they don't have to carry heavy bags out to the car.

1. By quoting (引用) the McDonald's ad, "We do it all for you", the author intends to ________.

A. suggest that customers believe what commercials say deeply

B. show readers the American idea on good customer service

C. express all the stores pay much attention to the customers

D. persuade readers to choose the stores with ads correctly

2. In the USA, what may you do at first if you want to do some shopping?

A. To visit a professional street with lots of similar stores.

B. To compare prices in many shops in the same street.

C. To make phone calls and get better shopping choices.

D. To receive other customers' answers to the questions.

3. Which of the followings shows American stores offer convenience to customers in this passage?

A. The store clerks don't usually sit around watching TV or playing cards.

B. Some stores offer price bargain to the customers like a yard sale.

C. The clerks give customers a smile and a warm "thank you" after paying.

D. Some stores open new checkout lanes when the lanes are crowded.
