(1) A longtime aide to President Bush who wrote occasional guest columns for his hometown newspaper resigned on Friday evening after admitted that he had repeatedly plagiarized from other writers. (2) The White House called his actions unaccepted. (3) The aide, Tim Goeglein, worked for Mr. Bush since 2001, as a liaison to social and religious conservatives, an important component of the president's political base. (4) Mr. Goeglein was influential in decisions on a range of question important to that constituency, including stem cell research, abortion and faith-based initiatives.

(6) “He is offered no excuses, and he agrees it was wrong.” (7) Mr. Goeglein, 44, is small known outside Washington. (8) He is a familiar figure to conservatives and evangelical Christians, who knew him as a spokesman for Gary L. Bauer, the conservative who ran as president in 2000.(9) When Mr. Bauer dropped out the race, Mr. Goeglein signed on with Mr. Bush, eventually becoming a top aide to Karl Rove, the chief political strategist. (10) He was the eyes and ears of the White House in the world of religion conservatives and an emissary to that world for Mr. Rove and the president.

Helicobacter pylori is one of humanity’s oldest and closest companions, and yet it took scientists more than a century to recognize it. As early as 1875, German anatomists found spiral bacteria colonizing the mucus layer of the human stomach, but because the organisms could not be grown in a pure culture, the results were ignored and then forgotten. It was not until 1982 that Australian doctors Barry J. Marshall and J. Robin Warren isolated the bacteria, allowing investigations of H pylori’s role in the stomach to begin in earnest. Over the next decade researchers discovered that people carrying the organisms had an increased risk of developing peptic ulcers—breaks in the lining of the stomach or duodenum—and that H pylori could also trigger the onset of the most common form of stomach cancer.Just as scientists were learning the importance of H pylori, however, they discovered that the bacteria are losing their foothold in the human digestive tract. Whereas nearly all adults in the developing would still carry the organism, its prevalence is much lower in developed countries such as the U.S. Epidemiologists believe that H pylori has been disappearing from developed nations for the past 100 years thanks to improved hygiene, which blocks the transmission of the bacteria, and to the widespread use of antibiotics. As H pylori has retreated, the rates of peptic ulcers and stomach cancer have dropped. But at the same time, diseases of the esophagus — including acid reflux disease and a particularly deadly type of esophageal cancer—have increased dramatically, and a wide body of evidence indicates that the rise of these illnesses is also related to the disappearance of H pylori.

2.Which of the following statements can be inferred from the passage?
3.Which of the following would most probably follow the last sentence of this passage?
A.alter people to the harm of H pylori colonization of the stomach B.make people aware of the harm of eradicating H pylori from the stomach C.suggest that the benefits of eradicating H pylori from the stomach are not outweighed by the potential harm. D.call attention to the consequences of eradicating H pylori from the stomach.问题2： A.Improvements in sanitation are a vital element in helping ward off peptic ulcers. B.People in the developing countries are not likely to contract esophageal diseases. C.Nowadays few people in the developed countries suffer from stomach cancer. D.Scientists have long recognized H pylori’s important role in the stomach, but could do nothing about.问题3： A.Furthermore, the disappearance of H pylori may be a sentinel indicating the possibility of other microbial extinctions as well. B.The possibility that this bacterium may actually protect people against disease of the esophagus has significant implications. C.However, there has been an unexpected rise in the incidence of a new class of diseases involving the esophagus. D.The rise of these diseases has occurred just as H pylori has been disappearing, and it is tempting to associate the two phenomena.Roger Rosenblatt's book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken by most previous studies. As Rosenblatt notes, criticism of black writing has often served as a pretext for expounding on Black history. Addison Gayle's recent work, for example, judges the value of Black fiction by overtly political standards, rating each work according to the notions of Black identity which it propounds.Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideolog
Asteroids and comets that repeatedly smashed into the early Earth covered the planet's surface with molten rock during its earliest days, but still may have left oases of water that could have supported the evolution of life, scientists say. The new study reveals that during the planet's infancy, the surface of the Earth was a hellish environment, but perhaps not as hellish as often thought, scientists added.Earth formed about 4. 5 billion years ago. The first 500 million years of its life are known as the Hadean Eon. Although this time amounts to more than 10 percent of Earth's history, little is known about it, since few rocks are known that are older than 3. 8 billion years old.For much of the Hadean, Earth and its sister worlds in the inner solar system were pumm

The contribution genes make to intelligence increases as children grow older. This goes against thenotion that most people hold that as we age，environmental influences gradually overpower the geneticlegacy we are bom with and may have implications for education. “People assume the genetic influencegoes down with age because the environmental differences between people pile up in life,”says RobertPlomin. “What we found was quite amazing, and goes in the other direction.”Previous studies have shown variations in intelligence are at least partly due to genetics. To find out whether this genetic contribution varies with age, Plomin’s team pooled data from six separate studies carried out in the US, the UK, Australia and the Netherlands, involving a total of 11,000 pairs of twins. In these studies, the researchers tested twins on reasoning, logic and arithmetics to measure a quantity called general cognitive ability, or “G”. Each study also included both identical twins, with the same genes, and fraternal twins, sharing about half their genes, making it possible to distinguish the contributions of genes and environment to their G scores.Plomin’s team calculated that in childhood, genes account for about 41 percent of the variation inintelligence. In adolescence, this rose to 55 percent； by young adolescence, it was 66 percent. No one knows why the influence from genes should increase with age, but Plomin suggests that as children getolder，they become better at exploiting and manipulating their environment to suit their genetic needs,and says “ Kids with high G will use their environment to foster their cognitive ability and choose friendswho are like-minded. ” Children with medium to low G may choose less challenging pastimes andactivities, further emphasizing their genetic legacy.Is there any way to interfere with the pattern? Perhaps. “The evidence of strong heritability doesn’tmean at all that there is nothing you can do about it，” says Susanne Jaeggi，“From our own work, theones that started off with lower IQ scores had higher gains after training. ’’Plomin suggests that genetic differences may be more emphasized if all children share an identical curriculum instead of it being tailored to children’s natural abilities. “My inclination would be to give everyone a good education, but put more effort into the lower end,” he says. Intelligence researcher Paul Thompson agrees: “It shows that educators need to steer kids towards things drawing out their natural talents.”
