The study adds to the already strong evidence that Helicobacter pylori bacteria can cause stomach cancer, a disease especially prevalent in Asia but far less mon in the United States. Still, experts said the findings do not solve the dilemma of whether and how to treat carriers of the bacteria.The study involved 1,630 men and women from Fujian Province in southern China. All were carriers of H. pylori。 hundreds of them already had precancerous lesions (癌變) at the outset of the study. Patients were randomly assigned to receive two weeks of treatment with antibiotics and an antiulcer drug, or a dummy medicine, and were followed for 7 years and a half after that. Among the 988 patients without precancerous lesions at the outset, none on the treatment got stomach cancer, pared with six in the placebo group. The findings among those with precancerous lesions were not as clearcut: Seven in the treatment group developed stomach cancer, versus 11 in the placebo group. The study appears in Wednesday39。s Journal of the American Medical Association. H. pylori is estimated to affect as many as 90 percent of people in some developing nations and up to 50 percent of people in some industrialized countries, according to the World Health Organization. Chronic H. pylori is thought to cause stomach cancer, and doctors have e to believe since the early 1980s that it is the No. 1 cause of ulcers.The findings suggest that doctors should consider routine screening for such lesions in H. pylori patients in highincidence areas, and treating the infections in patients with no precancerous lesions, said the authors, led by Benjamin ChunYu Wong of the University of Hong Kong.Dr. Michael Brown, a gastroenterologist at Rush University Medical Center in Chicago, said routine H. pylori screening would not be costeffective in the United States because the rates of infection and cancer are so low.46. According to the passage, experts in the Chinese study mentioned in the passage are still not sure _______.A. whether Helicobacter pylori bacteria can cause stomach cancerB. whether stomach cancer is more prevalent in Asia C. whether to treat all carriers of Helicobacter pylori bacteriaD. whether Helicobacter pylori bacteria can cause stomach ulcer47. Among people who developed cancer in the study, proportion of patients in the treatment group to patients in the placebo group is_____.A. 64%B. 50%C. 90%D. 39%48. In the study, what medicine did the placebo group take during the twoweek treatment?A. Antibiotics.B. A dummy medicine. C. An anticancer medicine.D. Medicine for the precancerous.49. How many patients in the study already had precancerous lesions at the outset of the study?A. 1467B. 988C. 815D. 64250. The findings of the study propose that ______.A. H. pylori patients in highincidence areas should be screened and treated.B. patients with precancerous lesions are not as easily cured as those without.C. treatment should be given to H. pylori patients without precancerous lesions.D. treatment should not be given to H. pylori patients with precancerous lesions.Passage 4NASA’s Goddard Space Flight Center in Greenbelt, Maryland has been given the nod to lead a robotic lunar mission in 2008 a key step in President George W. Bush’s recently announced space vision strategy. The lunar reconnaissance orbiter would likely be geared to investigate the potential for water ice trapped at the Moon’s poles. This type of investigation may involve powerful radar to scan the always darkened craters, thought by some scientists to contain bountiful quantities of water ice.Water ice is believed to have been brought to the Moon by impacting ets. Both NASA’s Lunar Prospector and the Pentagon’s Clementine spacecraft offered tantalizing data interpreted by some experts as indicative of water ice deposits.A number of alterative, fasttrack approaches are under review at the Goddard Space Flight Center (GSFC) to build the lunar orbiter. A newly formed GSFC lunar study team held their first meeting Thursday to begin scoping out how best to move the project forward.President Bush has directed NASA to undertake lunar exploration activities to enable sustained human and robotic exploration of Mars and more distant destinations in the solar system. Starting no later than 2008, the Bush plan calls for initiating a series of robotic missions to the Moon to prepare for and support future human exploration activities. A followon robotic lunar lander is also slated for 2009. The White House space directive states that the fir
