题目内容

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.

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 (毛虫). Parasitic wasps (寄生的黄蜂) 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.

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

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(证明…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(变异). 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(父子关系) 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

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
