Jeffrey Bezos, founder, president and chairman of the board of Amazon.com, was born in Albuquerque, New Mexico. His mother’s ancestors were early settlers in Texas, and over the generations had acquired a 25,000 acre farm at Cotulla. Jeffrey spent most summers of his youth working with his grandfather on their farm.
Jeffrey showed intense and varied scientific interests at an early age. He set up an electric alarm to keep his younger sisters and brothers out of his room and changed his parents’ garage into a laboratory for his science projects.
After he graduated from Princeton University with a degree in computer science and electrical engineering, Jeffrey Bezos found employment on Wall Street, where computer science was increasingly in demand to study market trends. He rose quickly, becoming a senior vice president, and looked forward to a bright career in finance, when he made a discovery that changed his life, and the course of business history.
In 1994, there was still no internet commerce to speak of. One day that spring, Jeffrey Bezos observed that Internet usage was increasing by 2300 percent a year. He saw an opportunity for a new circle of commerce, and immediately began considering the possibilities.
Bezos founded Amazon.com in 1994, setting up the original company in his garage. The company was called Amazon for the seemingly endless South American river with its numberless branches. It started as an online bookstore but soon diversified to all kinds of products. His work with Amazon eventually led him to become one of the most excellent dot-com entrepreneurs. He was named Time magazine’s Person of the Year in 1999. In 2008, he was selected by U.S. News & World Report as one of America’s Best Leaders. Bezos’ Amazon has become “the Earth’s biggest anything store”. Amazon.com is now called “one of the smartest strategies in business history”.
Today, Jeffrey Bezos lives north of Seattle and is increasingly concerned with charity activities. “Giving away money takes as much attention as building a successful company,” he said.
【小題1】 In his childhood, Bezos ______.

A.had to work with his grandfather on their farm all day long
B.showed great interest in science
C.didn’t get along well with his brothers and sisters
D.wanted to become a businessman

A.How hard Bezos studied in Princeton University.
B.“Amazon.com” only sold books in the beginning.

D.The reason why Jeffrey Bezos decided to found Amazon.com.
【小題4】 It can be inferred from the passage that ______.
A.it was Bezos’s grandfather on the farm who helped him a lot
B.Bezos invented e-commerce to win the world fame overnight
C.Bezos has a sharp business mind and a kind heart
D.Bezos aimed at setting up “the Earth’s biggest bookstore”

They travel in groups, noses just inches away form GPS screen. Suddenly a boy shouts “I found it!”, grinning and walking away from the group.
The others focus on their screens. “Me. too!” shouts another a moment later, until all six kids are crowded around a tree, pulling out a plastic bottle painted to look like tree bark. It doesn’t seem like much from the outside, but everyone gathers around, eager to see what’s inside.
This is geocaching, a high-tech game played using coordinates (坐標) and global positioning systems to find hidden “treasures”.
It’s open to anyone—hiders or seekers—with a GPS and access to www.geocaching.com, where more than half a million users download and upload the coordinates of nearly 1 million hidden caches (儲藏物) and write about their experiences in this worldwide hunt.
Although some adventures can take hours or even days, the contents inside the actual cache usually aren’t valuable—often just a book or a small trinket (小飾品).
But participants aren’t in it for the treasure. They say it’s a great way to exercise. Or it brings them to remote destinations or historical sites. Some consider it an extreme sport, looking for geocaches hidden in mountains or in other nearly inaccessible locations.
Jeffrey Howe, 41, sees it as an opportunity to take kids on adventures to unfamiliar places. The youths at the shelter mostly come form the city, but geocaching has taken them to parks, the suburbs, and, once, to a 498-meter-high mountain.
“Geocaching is a way to give kids the idea that there’s a whole world out there other than what they know from their home neighborhoods and video games,” he said.
How does it work? Log onto the Website and enter your zip code (郵編), then search for caches near your location. Although posted coordinates will take a GPS within about 4.5 meters of a cache, a good hide will require seekers to do a bit of hunting around. Caches can’t be buried underground, nor can they be hidden on private property (財產(chǎn)), in dangerous locations or in some national parks.
Posts written about the find—whether successful or unsuccessful—are an important part of the game, with users proudly recording the places to which they’ve traveled.

Science Daily (Apr 27, 2008) — Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean (地下的) and aboveground herbivorous (食草的) insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. This way, aboveground insects are warned that the plant is already “occupied”.
Aboveground, leaf-eating insects prefer plants that have not yet been occupied by subterranean root-eating insects. Subterranean insects send out chemical signals through the leaves of the plant, which warn the aboveground insects about their presence. This messaging makes it possible for spatially-separated insects to avoid each other, so that they do not compete for the same plant.
In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa (反之亦然). It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to notice each other. This avoids unnecessary competition.
Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely the natural enemy of caterpillars (毛蟲). Parasitic wasps (寄生的黃蜂) lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, as these help them find more insects for their eggs.
The communication between subterranean and aboveground insects has only been studied in a few cases. It is still not clear how widespread this phenomenon is. But scientists are looking into it. This research was carried out at the Netherlands Institute for Ecology (NIOO-KNAW) by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. The PhD project, in which this study was carried out, was funded by the Free Competition of NWO Earth and Life Sciences.
51. After finding a plant occupied by subterranean insects, aboveground insects usually ____.
A. send out warning signals             B. choose to give up the plant
C. compete for the plant               D. share it with the subterranean insects
52. Aboveground insects will develop more quickly if they ____.
A. feed on plants occupied by subterranean insects
B. feed on plants not occupied by subterranean insects
C. become cleverer through natural selection
D. compete with subterranean insects
53. Subterranean insects communicate with a third party through ____.
A. caterpillars     B. parasitic wasps    C. wasps’ eggs    D. a plant’s leaves
54. What can be inferred from the last paragraph?
A. Other animals may communicate in the same way.
B. There will be further research into this phenomenon.
C. Part of the study is a PhD project.
D. The Free Completion of NWO Earth and Life Sciences has the patent for these results.
55. What would be the best title for this passage?
A. Insects use plants as a telephone.         B. Insects live in harmony with each other.
C. No species can live alone.               D. Plants and animals have an effect on each other.

科目:高中英語 來源:2012屆江蘇省高二下學期期末考試(英語) 題型:閱讀理解

It happened one morning 20 years ago. A British scientist Alec Jeffrey came across DNA fingerprinting: He identified the patterns of genetic material that are unique to almost every individual. His discovery changed everything from the way we do criminal investigations to the way we decide family law. But the professor of genetics at the University of Leicester, UK, is still surprised, and a bit worried, by the power of the technology he released upon the world.

The patterns within DNA are unique to each individual, except identical twins, who share the same pattern. The ability to identify these patterns has been used to convict(證明…有罪) murderers and to clear people who are wrongly accused. It is also used to identify the victims of war and settle disputes over who is the father of a child.

Jeffrey said he and his colleagues made the discovery by accident while tracking genetic variations(變異). But, within six months of the discovery, genetic fingerprinting had been used in an immigration case, to prove that an African boy really was his parents’ son.·In 1986, it was used for the first time in a British criminal case: It cleared one suspect after being accused of two murders and helped convict another man.

DNA testing is now very common. In Britain, a national criminal database established in 1995 now contains 2.5 million DNA samples. The U.S. and Canada are developing similar systems. But there are fears about the stored DNA samples and how they could be used to harm a person’s privacy. That includes a person’s medical history, racial origin or psychological profile. “There is the long-term risk that people can get into these samples and start getting additional information about a person’s paternity(父子關系) or risk of disease,” Jeffrey said.

DNA testing is not an unfailing proof of identity. Still, it is considered a reasonably reliable system for determining the things it is used for. Jeffrey estimates the probability of two individuals’ DNA profiles matching in the most commonly used tests at one in a billion.

 

1.According to the text, DNA testing can NOT be used in _______ .

A. doing criminal investigations        B. deciding faraily law

C. clearmg wrongly accused people       D. telling twins apart

2.DNA samples are not popular with all the people because _______ .

A. the government in Britain establishes a criminal database

B. the US and Canada develop similar systems

C. DNA samples can be used to harm a person’s privacy

D. DNA testing is too expensive and dangerous now

3.Where will you most probably find this article?

A. In a guidebook.                      B. In a storybook.

C. In a science fiction.                D. In a scientific magazine.

4.Which is the best title for the passage?

A. Discovery of DNA testing by Jeffery    B. Practice of DNA testing in court

C. DNA testing in the present situation   D.Benefits and side effects of DNA testing
