The sea has always interested man. From it he can get food, minerals, and treasure. For thousands of years, he could sail on it. But he could not go far beneath its surface.
Man wants to explore deep into the sea. However, he is not a fish. He must breathe air, so he can’t stay under the water’s surface for any length of time. To explore deep water, man faces even more dangers and problems.
A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a hose(软管) and a mouthpiece. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea. His body is under great pressure.
When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles(气泡). The diver is then suffering from the bends(潜函病). The bends can cause a diver to double up in pain. They can even kill him.

No one likes to make mistakes. But a new study says organizations learn more from their failures than from their successes, and keep that knowledge longer.
One of the researchers was Vinit Desai, an assistant professor at the University of Colorado Denver Business School. He worked with Peter Madsen from the Marriott School of Management at Brigham Young University in Utah.
They did not find much long-term "organizational learning" from success. It is possible, they say. But Professor Desai says they found that knowledge gained from failure lasts for years. He says organizations should treat failures as a learning opportunity and not try to ignore them.
The study looked at companies and organizations that launch satellites--and other space vehicles. Professor Desai compared two shuttle flights.
In two thousand two, a piece of insulating(隔热的) material broke off during launch and damaged a rocket on the Atlantis. Still, the flight was considered a success.
Then, in early two thousand three, a piece of insulation struck the Columbia during launch. This time, the shuttle broke apart on re-entry and the seven crew members died. NASA officials suspended all flights and an investigation led to suggested changes.
Professor Desai says the search for solutions after a failure can make leaders more open-minded. He points to airlines as an example of an industry that has learned from failures in the past.
He advises organizations to look for useful information in small failures and failures they avoided. He also urges leaders to encourage the open sharing of information. The study appeared in the Academy of Management Journal.
The mistakes we learn from do not have to be our own. We recently asked people on our Facebook page to tell us a time they had done something really silly.
Fabricio Cmino wrote: Not long ago I wanted to watch TV, but it wouldn't turn on, so I did everything I could to start it. Thirty minutes later my mum showed up and, passing by, said to me "Did you try plugging it'? I’m just dusting, Mum!”So she wouldn't notice how dumb I am sometimes!

Ask most people how they define the American Dream and chances are they’ll say, “Success.” The dream of individual opportunity has been home in American since Europeans discovered a “new world” in the Western Hemisphere. Early immigrants like Hector St. Jean de Crevecoeur praised highly the freedom and opportunity to be found in this new land. His glowing descriptions of a classless society where anyone could attain success through honesty and hard work fired the imaginations of many European readers: in Letters from an American Farmer (1782) he wrote. “We are all excited at the spirit of an industry which is unfettered (无拘无束的) and unrestrained, because each person works for himself … We have no princes, for whom we toil (干苦力活)，starve, and bleed: we are the most perfect society now existing in the world.” The promise of a land where “the rewards of a man’s industry follow with equal steps the progress of his labor” drew poor immigrants from Europe and fueled national expansion into the western territories.
Our national mythology (神化) is full of illustration of the American success story. There’s Benjamin Franklin, the very model of the self-educated, self-made man, who rose from modest origins to become a well-known scientist, philosopher, and statesman. In the nineteenth century, Horatio Alger, a writer of fiction for young boys, became American’s best-selling author with rags-to-riches tales. The notion of success haunts us: we spend million every year reading about the rich and famous, learning how to “make a fortune in real estate with no money down,” and “dressing for success.” The myth of success has even invaded our personal relationships: today it’s as important to be “successful” in marriage or parenthoods as it is to come out on top in business.
But dreams easily turn into nightmares. Every American who hopes to “make it” also knows the fear of failure, because the myth of success inevitably implies comparison between the haves and the have-nots, the stars and the anonymous crowd. Under pressure of the myth, we become indulged in status symbols: we try to live in the “right” neighborhoods, wear the “right” clothes, eat the “right” foods. These symbols of distinction assure us and others that we believe strongly in the fundamental equality of all, yet strive as hard as we can to separate ourselves from our fellow citizens.What is the essence of the American Dream according to Crevecoeur?
| A．People are free to develop their power of imagination. |
| B．People who are honest and work hard can succeed. |
| C．People are free from exploitation and oppression. |
| D．People can fully enjoy individual freedom. |
By saying “the rewards of a man’s industry follow with equal steps the progress of his labor” (Line 10, Para. 1), the author means __________ .
| A．the more diligent one is, the bigger his returns |
| B．laborious work ensures the growth of an industry |
| C．a man’s business should be developed step by step |
| D．a company’s success depends on its employees’ hard work |
The characters described in Horatio Alger’s novels are people who ___________.
| A．succeed in real estate investment |
| B．earned enormous fortunes by chances |
| C．became wealthy after starting life very poor |

| B．Americans wish to succeed in every aspect of life |
| C．good personal relationships lead to business success |
| D．successful business people provide good care for their children |
What is the paradox (说法) of American culture according to the author?
| A．The American road to success is full of nightmares. |

| C．The American Dream is nothing but an empty dream. |
| D．What Americans strive after often contradicts their beliefs. |
Perhaps you think you could easily add to your happiness with more money. Strange as it may seem, if you're unsatisfied, the issue is not a lack of means to meet your desires but a lack of desires—not that you cannot satisfy your tastes but that you don't have enough tastes.
Real riches consist of well-developed and hearty capacities (能力) to enjoy life. Most people are already swamped(淹没) with things. They eat, wear, go and talk too much. They live in too big a house with too many rooms, yet their house of life is a hut.
Your house of life ought to be a mansion (豪宅) , a royal palace. Every new taste, every additional interest, every fresh enthusiasm adds a room. Here are several rooms your house of life should have.
Art should be a desire for you to develop simply because the world is full of beautiful things. If you only understood how to enjoy them and feed your spirit on them, they would make you as happy as to find plenty of ham and eggs when you're hungry.
Literature, classic literature, is a beautiful, richly furnished room where you might find many an hour of rest and refreshment. To gain that love would go toward making you a rich person, for a rich person is not someone who has a library but who likes a library.
Music like Mozart's and Bach's shouldn't be absent. Real riches are of the spirit. And when you've brought that spirit up to where classical music feeds it and makes you a little drunk, you have increased your thrills and bettered them. And life is a matter of thrills.
Sports, without which you remain poor, mean a lot in life. No matter who you are, you would be more human, and your house of life would be better supported against the had days, if you could, and did, play a bit.
Whatever rooms you might add to your house of life, the secret of enjoying life is to keep adding.The author intends to tell us that____________.
| A．true happiness lies in achieving wealth by fair means |
| B．big houses are people's most valued possessions |
| C．big houses can in a sense bring richness of life |
| D．true happiness comes from spiritual riches |
The underlined sentence in the second paragraph probably implies that__________.
| A．however materially rich, they never seem to be satisfied |
| B．however materially rich, they remain spiritually poor |
| C．though their house is big, they prefer a simple life |
| D．though their house is big, it seems to be a cage |
Larry was on another of his underwater expeditions(探险)but this time, it was different. He decided to take his daughter along with him. She was only ten years old. This would be her first trip with her father on what he had always been famous for.
Larry first began diving when he was his daughter’s age. Similarly, his father had taken him along on one of his expeditions. Since then, he had never looked back. Larry started out by renting diving suits from the small diving shop just along the shore. He had hated them. They were either too big or too small. Then, there was the instructor. He gave him a short lesson before allowing him into the water with his father. He had made an exception. Larry would never have been able to go down without at least five hours of theory and another similar number of hours on practical lessons with a guide. Children his age were not even allowed to dive.
After the first expedition, Larry’s later diving adventures only got better and better. There was never a dull moment. In his black and blue suit and with an oxygen tank fastened on his back, Larry dived from boats into the middle of the ocean. Dangerous areas did not prevent him from continuing his search. Sometimes, he was limited to a cage underwater but that did not bother him. At least, he was still able to take photographs of the underwater creatures.
Larry’s first expedition without his father was in the Cayman Islands. There were numerous diving spots in the area and Larry was determined to visit all of them. Fortunately for him, a man offered to take him around the different Spots for free. Larry didn’t even know what the time was, how many spots he dived into or how many photographs he had taken. The diving spots afforded such a wide array of fish and sea creatures that Larry saw more than thirty varieties of creatures.
Larry looked at his daughter. She looked as excited as he had been when he was her age. He hoped she would be able to continue the family tradition. Already, she looked like she was much braver than had been then. This was the key to a successful underwater expedition.What can be inferred from Paragraph2?
| A．Larry had some privileges. |
| B．Larry liked the rented diving suits. |
| C．Divers had to buy diving equipment. |
| D．Ten-year-old children were permitted to dive. |
Why did Larry have to stay in a cage underwater sometimes?
| A．To protect himself from danger. |
| B．To dive into the deep water. |
| C．To admire the underwater view. |
| D．To take photo more conveniently. |
Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)-either recorded or real-may even prevent elephants from damaging farmer's crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a close to each family.
From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy Played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.As mentioned in the passage, Lucy
| A．works by herself in Africa |
| B．needs to test more elephant groups |
| C．has stopped elephants eating crops |
| D．has got farmers to set up beehives on their farms |
Why did Lucy throw a stone into a wild beehive?
| A．To record the sound of bees. |
| B．To make a video of elephants. |
| C．To see if elephants would run away. |
| D．To find out more about the behavior of bees. |
Which of the following is true according to the passage?
| A．Young elephants ignore African honeybees. |
| B．Waterfalls can make elephants stay in one place. |
| C．Elephants do not go near trees with bees living in them. |
| D．Farmers do not allow Lucy to conduct tests in their fields. |
