At about $3.8 million for a 30-second spot, an ad on this year’s Super Bowl was easily the most expensive ad buy on television. For marketers, though, buying a spot during the big game may be the most efficient media play on Madison Avenue.

That’s only 1 (part) because of the huge audience for the game—111 million people watched last year, according to Nielsen.

The other major benefit of a Super Bowl ad is the free media attention the spots attract, which can more than justify their cost.

Super Bowl ads get a “ripple(波纹) of media that adds up to 2 (enormously) value above and beyond the spot itself,” says Tony Pace, chief marketing officer of Subway (赛百味—连锁快餐店)

The fast-food chain 3 (buy) two Super Bowl ads this year; one ad 4 (festure) its cast of pitchmen (广告员) including Jared Fogle and Olympian Apolo Ohno. The ads 5 (refer to) and written about in several newspapers and on several news websites.

Mr.Pace says he believes the spots, which his company made public only shortly before the game, would receive about a half-million dollars worth of free publicity even before the game airs.

Mercedes-Benz, another Super Bowl advertiser, agrees. Thanks in part to the publicity from media outlets, “we have easily recouped(收回) our investment,” says Steve Cannon, chief executive of Mercedes-Benz USA unit, which bought a 60-second ad during the game. Mr.Cannon declined to 6 (close) the luxury auto brand’s Super Bowl spending but he says it was an “eight-figure investment.” Mercedes-Benz, a unit of Germany’s Daimler AG, 7 (estimate) it has received about $20 million in free media 8 (cover) of the ad. It also has two outside public-relations firms working on generating media attention.

Over time the media coverage 9 (expand). In 2002, Pepsi Co estimated it got $10 million in free publicity for its 90-second Super Bowl ad featuring Britney Spears.

Many advertisers hire extra public-relations firms to help promote their Super Bowl spots to a growing list of interested media outlets, 10 (include) late-night talks shows, morning news programs, newspapers, and bloggers online video shows. 1._________ 2._________ 3._________ 4._________ 5._________ 6._________ 7._________ 8._________ 9._________ 10._________ 三、完形填空

Everyone dreams of being successful. Does anyone think of the mere question as to what elements 1 success, if there is any? Is there a “success personality”—some winning combination of qualities that leads almost 2 to achievement? If so, exactly what is that secret success formula, and can anyone develop it? At the Gallop Organization we recently focused in depth on success, inquiring into the opinions of 1,500 distinguished people selected at random from who’s who in America. Our research finds out a number of 3 that occur regularly among top achievers. Here is one of the most important, that is common sense.

Common sense is the most obvious quality 4 by our participants. Seventy－nine percent award themselves a top score in this quality. And Sixty－one percent say that common sense was very important in contributing to their success.

To most, common sense means the ability to present sound, practical judgments on everyday affairs. To do this, one has to sweep aside 5 ideas and get right to the key of what matters. A Texas oil and gas businessman puts it this way: “The key ability for success is simplifying. In conduction of meeting and dealing with industry, reducing a complex problem to

the simplest term is highly important.”

Is common sense a quality a person is born with, or can you do something to increase it? The oil man’s answer is that common sense can definitely be 6 . He owes his success to learning how to debate in school. Another way to 7 your store of common sense is to observe it in others, learning from their—and your own—mistakes.

Besides common sense, there are many other factors that 8 success: in order for you to achieve anything in your career, you have to first believe. You need to believe in yourself that you can achieve it, that is, you need to have 9 in your goals and your path to that success. However, nothing moves until you do something. Belief alone is not going to achieve anything for you. It must be followed up with concrete 10 . Your plan for career success is nothing unless you act upon it whole－heartedly.

( )1.A.define B.determine C.estimate D.prove ( )2.A.especially B.properly C.inevitably D.alternatively ( )3.A.challenges B.attractions C.qualifications D.qualities ( )4.A.possessed B.recommended C.proposed D.achieved ( )5.A.original B.common C.extra D.moderate ( )6.A.protected B.maintained C.observed D.developed ( )7.A.add to B.get over C.keep up D.go through ( )8.A.create B.influence C.judge D.attract ( )9.A.preparation B.attempt C.faith D.support ( )10.A.thought B.progress C.plan D.action 四、阅读理解

The seventh-inning stretch is one baseball tradition that helps make the game one of America’s favorite pastimes. In the middle of the seventh inning(局) fans ritualistically stand and stretch before the home team comes to bat.

No one really knows the origin of the custom, but there are theories on how it started. Baseball historian Dan Daniel provided this explanation: “It probably began as an expression of fatigue. That would explain why the stretch comes late in the game instead of at the halfway point.”

A more popular story involves President William Howard Taft and the birth of two baseball traditions. According to the account, Taft attended the first game of the 1910 baseball season. On the spur of the moment, plate umpire(裁判) Billy Evans gave Taft the ball. He asked him to throw it over the plate. Taft did so, and the custom of having the president launch the baseball season with the first pitch was born.

The story continues that later that same day. President Taft, who weighed well over 300 pounds, became uncomfortable in his small chair. In the middle of the seventh inning, he stood up to stretch his legs. The crowd thought that the president was leaving, so they stood up out of respect. A few moments later, Taft sat down again. The fans followed, and the seventh-inning stretch was born. What a day for traditions!

No matter how the tradition began, fans have since added to the fun. Now, as they stand to

stretch during the seventh inning, they can sing along to Jack Norworth’s 1927 version of the song “Take Me Out to the Ball Game” after the visiting team has batted.

( )1.Which of the following best defines the word “ritualistically” in Paragraph 1? A.Attracting attention. B.Showing excitement. C.Continuing a custom. D.Releasing anxiety.

( )2.The seventh-inning stretch is celebrated with the song “Take Me Out to the Ball Game” ________.

A.a few moments after the beginning

B.after the visiting team has batted in the seventh inning C.between the sixth and seventh innings

D.after the home team has batted in the seventh inning ( )3.In the more popular story, ________.

A.Billy Evans missed the first game of the 1910 baseball season B.Taft asked Billy Evans to throw the ball over the plate C.President Taft stood up to stretch his legs to relax himself D.the crowd thought the president didn’t respect the players ( )4.How did the custom of following the “seventh-inning stretch” begin? A.No one knows for sure where or when the custom began. B.Jack Norworth started the tradition with the song in 1927.

C.Fans used it as a time to stand and stretch their legs after sitting for the first six innings.

D.William Howard Taft stood up and the rest of the fans stood in honor of the president.

A.complexity B.images C.elementary D.signals E.willingly F.independently G.mental H.experiment I.leaps J.monster A noted American psychologist once remarked that childhood is a magical period in one’s life. Indeed it is, for during childhood, one undergoes a step-by-step transformation not only in 1 capacity, but also in physical and verbal skills. Each step 2 an increase in the difficulty of a child’s conceptual and learning abilities. During the early stages of childhood, from infancy to about five, the child learns simple skills including using the toilet, bathing and dressing himself 3 . At this stage, he also learns to be very observant, curious, imaginative and creative. His ability to remember things also 4 at this stage. He remembers details that an adult may have difficulty in remembering. Gradually, he learns 5 skills in problem-solving. At school, particular in art classes, the child is especially creative. Given a piece of paper and some colored pencils, he draws a variety of 6 from his surroundings as well as from his family circle. It is not surprising to see a child draw a(n) 7 to represent an abusive father, and an angel to represent a loving and caring mother.

As he graduates to the later stages of childhood bordering on the teenage years, the child learns the 8 of human relations and socialization by interacting with his peers his

friends and schoolmates. He also learns to 9 with new life situations, including dates and part-time work. Given a tight schedule of schoolwork, the child learns to prepare his own schedules of work and play; the more practical and less serious ones manage to take time out of their busy schedules of assignments, reports and tests and examinations to go with their friends on relaxation entertainment.

A.Make sure a sale is a sale. B.Use less to save money. C.Shop wisely. D.Shop in large amount. E.Establish a person budget. F.Spend less to save money. Saving money and being more economical is neither a science nor an art; rather it is somewhere in between and requires your commitment and hard work. Saving money takes time to develop, needs to be learnt, and brings benefits that will endure for the rest of your life. 1.________

Review what you spend and look at ways you can save money. Consider making telephone calls for instance only at off-peak times. Do you really need to have newspapers and magazines delivered? Can you do without those coffees you buy at break time everyday—would a flask of coffee taken to work save you money? What about using the public lending library instead of buying books or music CDs? 2.________

This is essential for families and individuals and can be the fastest way to save money. You will instantly see your incomings and outgoings once you figure out the amount of money available to spend. You will not be able to save money unless you know how much money you have coming in, and how much money you have going out. 3.________

Do your price research before you make an expensive purchase in a retailers promotion. You have to be sure the promotion really is not a creative marketing strategy of the store to encourage you to spend your money without thinking. Once you have researched the true price of a product (any product) you are in a good position to take advantage of a promotion，special offer or discount and really save money. 4.________

Consider markets, superstores, farmer’s markets, local shops and stores. Anywhere is worth checking out to see if you can save money. Farmer’s Markets can be particularly good places to save money. Typically you are buying direct from the producer of the product so the savings are passed on to you. Use your bulk buying strategy here—farmer’s markets often offer

opportunities to save money by buying larger quantities of staples, for instance potatoes, rice or corn. 5.________

We live in a consumer society where waste is a huge problem. If we could all use and consume less, there would be less waste and power consumption. Consider using less shampoo when you wash your hair, this may not mean washing your hair less effectively but it means not flushing the excess shampoo and your money down the drain. Tum off lights, the TV and the computer when they are not in use. Each little saving you make will build up and enable you to save money. 三、阅读理解

Barack Obama urged congressional leaders on Monday to act quickly to pass a huge stimulus package for the U．S. economy. He met with a bipartisan (concerning or involving two different political parties) group of lawmakers on Capitol Hill. Later he met individually with Democratic and Republican House and Senate leaders and spoke to a bipartisan leadership gathering. In comments to reporters early on Monday, he emphasized the urgency of finalizing economic legislation(立法). “We have got an extraordinary economic challenge ahead of us,” he said, “We are expecting a sobering job report at the end of the week. Nancy Pelosi and her staff have been extraordinarily helpful in working with our team so that we can shape an economic recovery and reinvestment plan that starts putting people back to work.”

Mr. Obama wants tax cuts for individual Americans and businesses to make up a significant portion of expected legislation. This could involve as much as $300 billion of a bill that is likely to go beyond $700 billion and include aid to cash-poor U．S. states, and money for alternative energy and a range of infrastructure(基础设施) projects. Later, Mr. Obama said he expects to be able to sign legislation as soon as the end of this month, adding that quick action is necessary to “break the drive of the U．S. economic depression”.

Emerging later from bipartisan talks with Mr. Obama, Nancy Pelosi said lawmakers discussed with the president how to pass a stimulus package as quickly as possible. “An economic recovery package that will create jobs immediately and will grow the economy and that is what we talked about today,” said Nancy Pelosi. “How we could do this fast, deliberatively and to act upon it soon.” Just how soon that would be, Pelosi would not say.

How much support Democrats can obtain from Republicans will depend on the details. But the severity of the U.S. economic depression has created considerable bipartisan backing for quick action. Senate Majority Leader, Harry Reid said：“There are investments that we need to make on behalf of the American people to turn around this economy. We felt very good about the meeting; we are confident that we can do this and we have to do this.”

“I think the best thing I can do is to decline to comment on what they are going to do going forward,” said Dana Perino. “Obviously, we think that tax cuts were the right way to help our economy get out of the economic depression that this president inherited and we know that tax cuts can stimulate innovation.” Asked by reporters how large the economic stimulus package might be, Senate Majority Leader Reid said Obama indicated that all but one of some 28

economists advising him had said it should range from $800 billion to $1.3 trillion.

( )1.Barack Obama urged congressional leaders and met with bipartisan leaders to _______. A.take over the White House B.end economic decline C.understand each other better D.negotiate political issues

( )2.If the stimulus package is passed quickly and successfully, it can________. A.obtain support from Republicans B.finalize economic legislation

C.enhance America's international position D.provide job opportunities

( )3.What is the bipartisan leaders’ attitude towards this meeting? A.Uncertain. B.Hopeful. C.Disappointed. D.Indifferent. ( )4.What can we infer from the passage?

A.The best way out of the economic depression is tax cuts.

B.The Republic Party plays the key role in coping with the economic depression. C.Democrats and Republicans will team up in the economic depression. D.When the stimulus package will be passed is known to the lawmakers. 四、根据短文内容，回答问题

A new study from Sweden found that men may be able to reduce their risk of having a stroke by about one-sixth, simply by eating one chocolate bar per week.

Researchers at Stockholm’s Karolinska Institute followed more than 37,000 men between the ages of 45 and 79 for about 10 years. Compared to those who ate little or no chocolate, men who ate the most—about 2.2 ounces per week—had a 17% lower risk of having a stroke during that time span.

The study adds to the growing evidence that chocolate, or even cocoa, has some heart－healthy properties. Cocoa contains flavonoids, compounds that have been shown to lower blood pressure. As a type of antioxidant, flavonoids can also thin the blood and improve the function of blood vessels. Therefore, it could help prevent heart attacks and strokes.

As the researchers note, however, besides the substances in chocolate—or, more likely, certain traits associated with chocolate lovers—could also easily explain the findings. The study participants who ate more chocolate tended as a group to be better educated and healthier than their peers. They were less likely to smoke or have high blood pressure. Fayad, a professor of neurological sciences at the University of Nebraska Medical Center, in Omaha, says, “This association could also be due to the fact that (chocolate eaters) are healthier people, It’s possible that the link between chocolate consumption and strokes can be explained by health or lifestyle differences that went undetected”.

However, another professor Friedman adds, “when it comes to chocolate consumption, moderation is the key. Eating five chocolate bars a week might be worse for you in terms of

obesity than it is good for you in terms of stroke risk.”

“Actually, following a healthy diet, exercising regularly, and treating known risk factors such as high blood pressure will all have a bigger impact on stroke risk than chocolate consumption”, Fayad says.

(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)

1.The research by Stockholm’s Karolinska Institute shows that ________ can help to decrease the risk of having a stroke.

2.In addition to lowering blood pressure, flavonoids make contributions to ________. 3.What can account for the link between chocolate consumption and strokes according to Fayad?

4.Why is moderate chocolate consumption important?
