Conventional wisdom is a major barrier to innovation(創(chuàng)新) that threatens the survival of companies everywhere. It’s based on the assumption that old ideas will always work, so they shouldn’t be challenged. While this may be a valid assumption in situations that don’t change, it’s unlikely to hold true in a changing situation. In today’s rapid changing global environment, old methods often don't work, and stubbornly using them can lead to major problems.

Most people seem to agree with conventional wisdom because it gives one a false sense of security. If everyone else believes it, then it must be true. Individuals who use conventional wisdom are certain that they are right, and being right is good. They want to continue using old ideas rather than take risks with changes that might not work. In 1977, Ken Olsen, co-founder and CEO of Digital Equipment Corporation (DEC), stated “There is no reason for any individual to have a computer in his home.” Despite being a dominant leader in the computer industry, DEC no longer exists.

People seem to forget that since innovation is a change, there can be no innovation without change. Unfortunately, conventional wisdom prevents leaders, followers and companies from changing and therefore innovating. If companies don’t innovate, but their competitors do, the future is likely to be problematic. Breaking from conventional wisdom has led to many of the most innovative companies and products in history across many industries, so it has a powerful effect on business success.

Ted Turner (founder of CNN) knew little, if anything, about the news business, but he knew it was inconvenient to watch news only at the dinner hour, as was common before CNN. Turner’s solution was to create a cable channel dedicated to news 24 hours a day. The news establishment reflected conventional wisdom at the time, and predicted his idea would fail because no one wanted to watch the news all day. However, it doesn’t take a rocket scientist to understand that viewers don’t have to watch the news all day for the CNN to work. Viewers just have to watch when they want to get information. Due to conventional thinking, the critics failed to recognize the opportunity that was clear to Ted. They assumed that only what was familiar to them could work in the future.

Conventional wisdom prevents creativity, flexibility and risk-taking, so unconventional leaders enthusiastically break from it. To survive, thrive and maintain competitive advantage, companies must be flexible when reacting to change.

1.DEC has disappeared probably because ___________.

A. the CEO stuck to the conventional ideas

B. the leaders lacked the sense of security

C. the consumers didn’t like its products

D. the employees took many risks with changes

2. The founding of CNN is used as an example to prove _________.

A. missing opportunities could lead to failure

B. conventional wisdom influences business success

C. watching news at the dinner hour is convenient

D. changing could contribute to business success

3. What does the underlined part probably mean?

A. Rocket scientists can ensure the CNN works properly.

B. It’s easy to know people needn’t watch the news all the time

C. It’s necessary to understand when people watch the news.

D. Most of the viewers don’t like to watch the news at work.

4.The passage is mainly written to tell us that ______.

A. conventional wisdom limits innovation

B. opportunities lead to business success

C. old methods are changing with time

D. successful companies need wise leaders

Eco City Farms(生態(tài)城市農場) are becoming more popular in cities and towns around the United states.

Eco City Farms in Edmonton, Maryland, is located near shopping centers, car repair shops and homes. The neighborhood is a working-class community(社區(qū)). People do not have very much money. And they have limited access (獲得)to fresh food in markets.

Traveling without a map in different countries，I find out about different “styles” of directions every time I ask “How can I get to the post office?”

Foreign tourists are often confused in Japan because most streets there don’t have name signs：in Japan，people use landmarks in their directions instead of street names．For example，the Japanese will say to travelers，“Go straight down to the corner．Turn left at the big hotel and go past a fruit market．The post office is across from the bus stop．”

People in Los Angeles，the US，have no idea of distance on the map：they measure distance by time，not miles．“How far away is the post office?” you ask．“Oh,” they answer，“it’s about five minutes from here．” You don’t understand completely，“Yes，but how many miles away is it，please?” To this question you won’t get an answer，because most probably they don’t know it themselves．

People in Greece sometimes do not even try to give directions because tourists seldom understand the Greek language．Instead，a Greek will often say,“ Follow me．”Then he’ll lead you through the streets of the city to the post office．

Sometimes a person doesn’t know the answer to your question．What happens in the situation? A New Yorker might say，“Sorry, I have no idea．”But in Yucatan，Mexico，no one answers “I don’t know．” People there believe that “I don’t” is impolite．They usually give an answer，but often a wrong one．So a tourist can get lost very easily in Yucatan!

However，one thing will help you everywhere in the world．It’s body language．

1.Which of the following is probably an example of Japanese directions?

A．“Go south two miles．Turn west and then go another mile．”

B．“Turn right at the hospital and go past a school．”

C．“The post office is about five minutes from here．”

D．“The post office is at Street Kamira．”

2.Why don’t people in Los Angeles give directions in miles?

A．They use landmarks in their directions instead of distance．

B．They prefer to lead you the way．

C．They often have no idea of distance measured by miles．

D．They prefer to use body language．

3.How do Greeks give directions?

A．Using street names

B．Using landmarks

C．Leading people the way

D．Giving people a wrong direction

4.Where is Yucatan?

Researchers around the world have been trying their hand at making better use of the huge amount of wind energy available in nature to produce clean energy. Apart from this, studies are being carried out to harness(利用) usable wind energy produced by man-made technologies.

One useful source identified by Indian inventor Santosh Pradhan about two years ago is a speeding train, which produces fierce wind that can be transformed into electricity.

According to Pradhan’s proposal, with a few small improvements in existing trains running in Mumbai, the largest city in India, at least 10,000 megawatts(兆瓦) of electricity could be harvested each day.

Building on this principle, designers Ale Leonetti Luparinia and Qian Jiang from Yanko Design have created a device(裝置) called T-Box that harnesses wind energy from speeding trains.

T-Box can be placed within the railway tracks. It is half-buried underground between the concrete sleepers(水泥枕木), which does not disturb the normal train operating at all. According to Yanko, around 150 T-Boxes can be fitted along a 1,000-meter railway track.

A train running at a speed of 200 kph can produce winds blowing at 15 miles a second. Based on this calculation, 150 T-Boxes can produce 2.6 KWH of electricity per day. The T-Box’s design won a silver medal in last year’s Lite-On Awards and was exhibited last summer at the Xue Xue Institute in Taipei, Taiwan Province.

Though the figures look impressive, it is important to remember that the design is still at a conceptual stage and hasn’t taken into account issues such as pieces of waste material produced by the device and the efforts and costs involved in the maintenance(維護) of the device.

We can expect the technology to see the light of the day only after it clears these issues. If so, rail travel, one of the greenest forms of travel, will become greener and more energy-efficient.

1.What can we learn about T-Box?

A. It will be fitted on the trains.

B. It is based on Pradhan’s idea.

C. It can turn electricity into light.

D. It was invented by an Indian scientist.

2.How much electricity can be produced per day by T-Boxes along a railway track of 100km?

A. 260 KWH. B. 2.6 KWH.

C. 150 KWH. D. 1.5 KWH.

3. It can be concluded from the last two paragraphs that ______.

A. T-Box has proved to be effective in harvesting wind

B. the maintenance of T-Box will be costly

C. there is much to do about T-Box

D. T-Box will come into use soon

4.According to the passage, which of the following statements is TRUE?

A. The Indian inventor Santosh Pradhan invented the speeding train.

B. The T-Box’s design won a silver medal in Lite-On Awards last year.[來源:Z

C. Rail travel has become one of the energy-efficient technologies in the world.

D. The India harvests 10,000 megawatts of electricity each day on average.

5.The passage is mainly written to _______.

A. encourage more people to travel by train

B. explain the advantages of electricity

C. tell readers how to save energy and money

D. introduce a new invention to readers

Deep in the wilderness of northern Kenya, two boys found a pair of crying cheetah cubs (獵豹幼崽). The cubs' mother had been killed by a lion. The cheetahs were only a few weeks old. In the wild, about 9 out of 10 cheetah cubs die before they are three months old. They are food for lions. But these cubs were so lucky that they were saved by their "heroes", who brought them to Jane and Ian Craig. The Craigs help save endangered animals at the Lewa Wildlife Conservancy.

The Craigs nursed the cheetah cubs back to health — feeding them with bottles, sleeping with them, and comforting them. They named the cubs Sambu and Toki. But what would become of these cubs? How would they survive on their own? In the wild, cubs stay with their mothers until they are almost 2 years old. During that time, cheetah mothers teach their young how to hunt and how to protect themselves. The Craigs wouldn't be able to find a cheetah mother to teach the cubs. So they turned to a man named Simon King.

King has spent more than twenty years studying cheetahs. He gave them a nod of approval when hearing about this, though taking care of two baby cubs would take a huge amount of time. For two years, he would need to have them at his side most of the time. But he felt there was no other choice. And so, when the brothers were one month old, King became their father.

The brothers followed King everywhere. If they saw large dangerous and fierce mammals, King would growl at the cubs the way a mother cheetah would have, which was a signal for the cubs to stay away. They learned quickly. King taught the cheetahs to hunt using a toy rabbit as King pulled it around on a rope. With more lessons and training, the brothers began to hunt on their own. King is one proud father now.

1.What do we know about the two cheetah cubs?

A.They like the Craigs very much.

B. Their lives were in danger in the wild.

C. Their mother was killed by humans.

D. They were not afraid of lions.

2.What worried the Craigs?

A. There was no cheetah mother to teach the cubs.

B. The cubs were dangerous.

C. They had no time to take care of the cubs.

D. There was no living place for the cubs.

3.The cheetah brothers learnt hunting skills from ________.

A. Simon King B. the boys

C. the Craigs D. their mother

4.In which part of a magazine would we expect to find this text?

We Chinese are not big huggers. A handshake or a pat on the shoulder is enough to express our friendship or affection (love) to one another. So when our newly-acquainted Western friends reach out in preparation for a hug, some of us feel awkward. Many questions go through our head. Where should I put my arms? Under their armpits or around their neck? What distance should I keep? Should our chests touch?

It’s even more difficult with friends from some European countries. Should I kiss them on the cheek while hugging? Which side? Or is it both cheeks? Which side should I start on?

But it isn’t just people from cultures that are conservative(保守的) in expressing physical contact who find hugging confusing．Hugs can cause discomfort or even distress(pain) in people who value their personal space．

In a recent article for The Wall Street Journal, US psychologist Peggy Drexler said that although the US remains a “medium touch” culture, Americans do seem to be hugging more. From politicians to celebrities（famous people）, hugs are given to friends, strangers and enemies alike; whether they are willing or not; and the public has been quick to pick up the practice.

Public figures know that nothing expresses likeability(親和力)like a good hug. US First Lady Michelle Obama has put her arms around icy foreign leaders like Russian Prime Minister Dmitry Medvedev and the Queen of England on the latter occasion actually breaking the rule of royal manners.

But not all are grateful to be embraced(hugged), even by the most influential and famous. To them, any hug is offensive(冒犯的) if it’s not sincere.

Amanda Hess, writing for US magazine Slate, says public figures should stop imposing（強加） hugs on everyone they meet. For them, a hug is rarely a gesture of sincere fellowship, compassion or affection. It’s all part of a show. Hugs are falsely intimate power plays used by public figures to establish their social dominance(主導) over those in their grasp.

Cecilia Walden, a British journalist writing for The Telegraph who lives in New York, holds the same opinion. “Power-hugging”, as she calls it, is “an offender dressed up as kindness”. It has become a fashion in the US where “bosses are already embracing their staff (either shortly before or after firing them), men and women ,their friends or enemies, in a thousand cheating displays of unity”.

1.From the first third paragraphs, we can see that ___________.

A. we Chinese people don’t know how to hug

B hugs can bring pressure to people when used improperly

C. people from European countries often get puzzled about hugging

D. people in Western countries seldom use hugs to express their physical closeness

2.The example of US first lady Michelle Obama is given to show that __________.

A. hugs are forbidden in England

B. she is much liked by American people

C. Americans hold a “medium touch ”culture

D. public figures know hugging functions well in public

3.Which of the following is closest in meaning to the underlined phrase “pick up the practice”?

A．Follow the trend．

B．Enjoy the medium touch culture．

C．Give hugs to enemies．

D．Resist physical touch．

4.What can be the best title of this passage?

A. Hugs, tricky affair? B. Hugs, vital or not?

C. Hugs and public figures D. Hugs and power
