3 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the following passage in no more than 60 words. Use your own words as far as possible.

With the arrival of the age of “information economy”, intellectual work is becoming a more important source of wealth than manufacturing. Organizations in all walks of life are doing more to spread their information. So people of the Public Relations are hired to speak for them. A lot of our news is actually collected from press releases and reports of events intentionally staged for journalists. In the information age, journalists spend their time, not investigating, but passing on the words of a spokesperson.

There is a joke in the novel Scoop about the newspaper's owner, Lord Copper. The editors can never disagree with him. When he's right about something they answer “definitely”, and when he's wrong they say “to some extent, Lord Copper.” It seems reasonable to suppose that, in the real world, the opinions of such powerful people still influence the journalists and editors who work for them.

In countries where the news is not officially controlled, it may be provided by commercial organizations who depend on advertising. The news has to attract viewers and maintain its audience ratings. I suspect that some stories get air-time just because there happen to be exciting pictures to show.

There is an argument that with spreading access to the Internet and cheap technology for recording sound and images we will all be able to find exactly the information we want. People around the world will be able to publish their own eye-witness accounts and compete with the widely-accepted news-gatherers on equal terms.

Maybe the time has come to do something about it, and I don't just mean changing your choice of TV channel or newspaper. In a world where everyone wants you to listen to their version, you only have two choices: switch off altogether or start looking for sources you can trust.

4 . The notion of building brand personality is promoted by Starbucks as a part of company culture to embed meaning in their products and thus attract more customers.

Starbucks literally changed the definition of “a good cup of coffee”. For Starbucks, the brand had three elements: coffee, ________ and stores.

Outstanding store personnel were employed and trained in coffee knowledge and ________ service. Store design, atmosphere and aroma (浓香) all ________ the “Starbucks Experience”.

Almost all Starbucks stores were corporately owned and controlled. Starbucks prided itself on the “Starbucks Experience”, ________ coffee to provide a unique experience for its customers.

You get great people, first-rate music, a comfortable and upbeat meeting place, and ________ advice on brewing excellent coffee at home. At home you’re part of a family. At work you’re part of a company. And somewhere in between is a place where you can sit back and be yourself. That’s what a Starbucks store has been ________ to creating for its customers — a kind of “third place” where they can ________, reflect, read, chat or listen.

The green Starbucks logo is a mermaid that looks like the end of the double image of the sea. It was designed by Terry Heckler, who got the ________ from the wooden statue of the sea. Mermaid logo also ________ original and modern meanings: her face is very simple, but with modern abstract forms of packaging; the middle is black and white, the only color on the outside surrounded by a circle.

Starbucks makes the typical American culture gradually broken down into elements of ______: the visual warmth, hearing the way, smelling the aroma of coffee and so on. Just think, through the huge glass windows, watching the crowded streets, ________ sipping a coffee flavor, which is in line with the “Yapi”, the feeling of experience in the ________ life.

6 . Eating fast food makes people impatient even when they are not short of time, a new study claims.

Students in the study became _______ even when shown the logo of burger chain McDonald’s so quickly on screen that they could not _______ it.

Researchers say that daily exposure to fast food brands could have a subliminal (潜意识的) effect on _______   making people hurry regardless of whether they are pushed for time. They conclude: “Our experiments suggest that the _______ goal of saving time embedded in fast food may have the unexpected consequence of causing hurriedness and impatience.”

Thinking about fast food increases _______ for time-saving products. “More _______, we found that the mere exposure to fast food symbols reduced people’s willingness to save and led them to prefer immediate _______ over greater future return, finally harming their economic interest.”

Student volunteers were quickly shown six logos from fast-food chains — McDonald’s, Burger King, KFC, Subway, Wendy’s and Taco Bell. They could not consciously see what they were but the subliminal effect was _______. Their reading speed was measured before and after seeing the logos and it was significantly faster afterwards. Participants also preferred time-saving products like three-in-one skincare treatments rather than _______ versions after seeing the logos. When asked weather they would accept a small sum of money immediately or a larger amount in a week’s time, they again chose __________ reward after being exposed to the brands.

Researcher Chen-Bo Zhong, assistant professor of organizational behaviour at Canada’s Toronto University, said: “Fast food represents a culture of time efficiency and immediate __________ The problem is that the goal of saving time gets activated upon exposure to fast food __________ whether time is a relevant factor in the context. “__________, walking faster is time-efficient when one is trying to make a meeting, but it’s a sign of impatience when one is taking a walk in the park.”

“We’re finding that the mere exposure to fast food is __________ a general sense of hurriedness and impatience. When I sit in a fast food restaurant, I find myself gobbling (狼吞虎咽) my Big Mac down at this incredible speed even though there is no __________ at all.”

7 . Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.

The sights, sounds, and smells of the modern marketplace are rarely accidental. More likely, they are tools of an evolving strategy of psychological marketing called “sensory marketing” to create an emotional association to a(n) ______ product or brand.

By relating to people in a far more ______way through everyone’s own senses,   sensory marketing is able to affect people in a way that traditional mass marketing cannot.

Traditional marketing believes that consumers will systematically consider______ product factors like price, features, and utility. Sensory marketing, by contrast, seeks to resort to the consumer's life experiences and feelings. Sensory marketing believes that people, as consumers, will act according to their emotional urge more than to their ______ reasoning. In this way, an effective sensory marketing effort can result in consumers choosing to buy a lovely but expensive product, rather than a plain but cheap ______.

In the past, communications with customers were mainly monologues — companies just ‘talked at’ consumers. Then they evolved into dialogues, with customers providing ______. Now they’re becoming multidimensional conversations, with products finding their own voices and consumers responding ______ to them.

Based on the implied messages received through five senses, consumers, without noticing it, tend to apply human-like personalities to brands, leading to intimate relationship and, hopefully for the brands, persistent ______. And that’s the very thing brands are dying to foster in customers rather than instant trend or profits.   Most brands are considered to have either "sincere" or "exciting" personalities.

"Sincere" brands like IBM and Boeing tend to be regarded as conservative and reliable while "exciting" brands like Apple, and Ferrari are as imaginative and ______. In general, consumers tend to form ______ relationships with sincere brands than with exciting ones. This explains the relatively enduring history of the “Sincere Brands”

Certainly, with the eyes containing two-thirds of all the ______cells in a person's body, sight is considered the most important of all human senses. Sensory marketing uses sight to create a memorable "sight experience" of the product for consumers which extends to packaging, store interiors, and printed advertising to form a(n) ___ image for the brand.

In other words, no aspect of a product design is left to ______ anymore, especially color. Brand acceptance is linked closely with the appropriateness of the colors on the brand—does the color ______ the product at all?   If not, customers, though not realizing it themselves, will _____ the brands in all possible ways sales, reputation, etc.   Therefore, brands, isn’t it time now to study the new field of marketing?

8 . The modern Olympic Games, founded in 1896, began as contests between individuals, rather than among nations, with the hope of promoting world peace through sportsmanship. In the beginning, the games were open only to _______. An amateur is a person whose involvement in an activity - from sports to science or the arts - is purely for ________. Amateurs, whatever their contributions to a field, expect to receive no form of compensation; professionals, ________, perform their work in order to earn a living.

From the perspective of many athletes, ________, the Olympic playing field has been far from fair. Restricting the Olympics to amateurs has excluded the participation of many who could not afford to be _______. Countries have always desired to send their best athletes, not their ________ ones, to the Olympic Games.

A slender and imprecise line separates what we call “financial support” from “earning money.” Do athletes “earn money” if they are reimbursed for travel expenses? What if they are paid for time lost at work or if they accept free clothing from a manufacturer or if they teach sports for a living? The runner Eric Liddell was the son of poor missionaries; in 1924 the British Olympic Committee ________ his trip to the Olympics, where he won a gold and a bronze medal. College scholarships and support from the United States Olympic Committee made it possible for American track stars Jesse Owens and Wilma Rudolph and speed skater Dan Jansen to train and compete. When the Soviet Union and its allies joined the games in 1952, the ________ of amateur became still less clear. Their athletes did not have to ________ work and training because as citizens in communist regimes, their government financial support was not considered payment for jobs.

In 1971 the International Olympic Committee (IOC) ________ the word amateur from the rules, making it easier for athletes to find the ________ necessary to train and compete. In 1986, the IOC allowed professional athletes into the games.

There are those who ________ the disappearance of amateurism from the Olympic Games. For them the games ________ something special when they became just another way for athletes to earn money. Others say that the designation(命名) of amateurism was always ________; they argue that all competitors receive so much financial support as to make them paid professionals. Most agree, however, that the ________ over what constitutes(组成) an amateur will continue for a long time.

9 . Though people have discussed the relationship between science and nature for many years, there is no consensual(统一的) explanation. While some view science as a powerful tool in ______ nature’s source of power, others view it as a danger. One example is Barry Commoner’s article, Unraveling(解开) the DNA Myth, which explains the recent developments in DNA technology and expresses ______. Another example is Nathaniel Hawthorne’s short story, The Birthmark. It is a tale about a famous scientist, Aylmer, who seems to be unraveling nature’s deepest secrets one by one. Despite all of his ______ and vast understanding of science, Aylmer is unable to direct that knowledge into ______ free from nature’s grasp. He was unable to rid his wife of her birthmark and, in the end, killed her.

Despite the different presentations of the concepts, though time separated the two men, both pieces express a similar view on the relationship between science and nature. Both pieces suggest that nature is ______ and holds wonders, secrets, and powers that many scientists constantly dream about discovering. Although there is a gap of one hundred and sixty years, Commoner still shares and gives evidence to Hawthorne’s beliefs that there is a unique ______ in nature that cannot be discovered or understood through science and that the ______ to uncover nature’s secrets are ______ and can lead to disaster. According to Commoner, nature’s universal power continues to prevent and control their discoveries. Commoner criticizes and ______ doubt on the true power of science.

As Commoner’s article suggests, nature only allows science to have limited power and success. Both men believe that complete trust in science is ______, however wonderful and groundbreaking some scientific discoveries are. Commoner believes that people only seem to focus on the few achievements, while avoiding and ignoring all of the laws. For example, “most clones exhibit developmental failure before or soon after birth”. By stressing all of the ______ and shortcomings of science, he conveys the notion that nature’s secrets are well kept and far from being understood and ______ by man. The government and private companies have invested billions of dollars in mapping the human genome, but we still have no ______ for it. Such a discovery is useless, however interesting it might be.

Commoner’s article clearly represents science as weak and useless, but more importantly, dangerous. It gives evidence to support the suggested dangers ______ with science’s attempts to discover nature’s power. If the result is not ______ dangerous, it can still have harmful side effects.

A.buildingB.definingC.showingD.uncovering

10 . Before the age of the smartphone, photographers had to learn how to use high-tech cameras and photographic techniques. Today, with the huge range of camera apps on our smartphones, we’re all good amateur photographers, since the quality of smartphone images now nearly equals that of digital cameras.

The new ease of photography has given us a tremendous appetite for capturing the magical and the ordinary. We are obsessed with documenting everyday moments, whether it’s a shot of our breakfast, our cat or the cat’s breakfast. Even photo journalists are experimenting with mobile phones because their near invisibility makes it easier to capture unguarded moments.

In the past, magazines published unforgettable photos of important people and global events that captured our imaginations. These photos had the power to change public opinion and even the course of history. But if there are fewer memorable images today, it’s not because there are fewer good images. It’s because there are so many, and no one image gets to be special for long.

As people everywhere embrace photography and the media make use of citizen journalists, professional standards appear to be shifting. Before digital images, most people trusted photographs to accurately reflect reality. Today, images can be altered in ways the naked eye might never notice. Photojournalists are trained to accurately represent what they witness. Yet any image can be altered to create an “improved” picture of reality. The average viewer is left with no way to assess the accuracy of an image except through trust in a news organization or photographer.

The question of the accuracy of images gets even trickier when photojournalists start experimenting with camera apps-- like Hipstamatic or Instagram --- which encourage the use of filters (滤镜). Images can be colored, brightened, faded, and scratched to make photographs more artistic, or to give them an antique look. Photographers using camera apps to cover wars and conflicts have created powerful images--- but also controversy. Critics worry that antique-looking photographs romanticize war, while distancing us from those who fight in them.

Yet photography has always been more subjective than we assume. Each picture is a result of a series of decisions-- where to stand, what lens to use, what to leave in and what to leave out of the frame. Does altering photographs with camera app filters make them less true? There’s something powerful and exciting about the experiment the digital age has forced upon us. These new tools make it easier to tell our own stories--- and they give others the power to do the same. Many members of the media get stuck on the same stories, focusing on elections, governments, wars, and disasters, and in the process, miss out on the less dramatic images of daily life that can be as revealing.

Who knows? Our obsession with documentation and constantly being connected could lead to a dramatic change in our way of being. Perhaps we are witnessing the development of a universal visual language, one that could change the way we relate to each other and the world. Of course, as with any language, there will be those who produce poetry and those who make shopping lists.

1. According to the author, there are fewer memorable photographs today because_________.
A.the quality of many images is still poor
B.there are so many good images these days
C.traditional media refuse to allow amateur photos
D.most images are not appealing to a global audience
2. The author put the word “ improved” in quotation marks in order to _________.
A.indicate it’s a word cited from another source
B.stress that the picture of reality is greatly improved
C.draw audience attention to a word worth considering
D.show it’s arguable whether the picture is truly improved
3. Which of the statements does the author most likely agree with?
A.The daily life pictures are very expressive themselves.
B.Photographs of the digital age are more subjective than before.
C.Photos altered by filters of camera apps are too subjective to be true.
D.Many members of the media value daily life images over major social events.
4. What may be the best title for the passage?
A.Camera Apps Bury Authenticity
B.Photography Redefined: A Visual Language
C.Smartphone: Killer of Professional Photography
D.The Shifting Standards of Professional Photography
