PART II READING COMPREHENSION
SECTION A MULTIPLE-CHOICE QUESTIONSIn this ction there are veral passages followed by fourteen multiple-choice questions. For each multiple-choice question, there are four suggested answers marked [A] , [B], [C] and [D]. Choo the one that you think is the best answer.
(1)With the toll from anthrax mounting, the antibiotic most commonly ud to tackle the deadly bug is now a celebrity. News anchor Tom Brokaw recently held a bottle up to the camera, saying: 词怎么组词“In Cipro we trust.” (2)Sadly, that trust could be short-lived. Cipro 姓水“may have the dubious distinction of being the antibiotic we destroy faster than any other”, warns microbiologist Abigail A. Salyers at the University of Illinois. The problem is that bacteria are immenly adaptable critters. Expo them to antibiotics long enough, and they纸鸢飞’ll evolve wa

(3)Infectious-dia experts stress that people expod to anthrax, such as postal workers in affected mail centers, should take Cipro, at least until tests show either that they don’t have the bug or that their bacterial strain is susceptible to other drugs. But tho who gulp down Cipro merely out of fear are being dangerously irresponsible, putting both themlves and others at risk. (4)Why? The human body teems with bacteria. A broad-bad antibiotic such as Cipro acts like a neutron bomb on this ecosystem, wiping out billions of microbes. Not only can that impair normal body functions in which bacteria play a role, such as digestion, but harmful germs can move in, like squatters taking over suddenly vacant hous. (5)CRYING WOLF. Wor, antibiotics breed resistance. When you take a drug, the hardest bacteria among constantly mutating strains survive, reproduce, and pass along defen mechanisms against drugs. Taking Cipro for weeks “is the perfect situation for the regular bacteria in the body to become resistant”, says Dr. Carol J. Baker, a pediatrician at Baylor College of Medicine and president of the Infectious Dia Society of America. Except in the ca of an actual anthrax infection—rather than more exposure—it’s best to take the antibiotic

Painful infections result when benign gut flora, such as E. coli, find their way to the urinary tract. Streptococcus bugs that live harmlessly in the throat cau pneumonia if they get into the lungs. Contract one of the dias, and your doctor may prescribe Cipro. But if you’ve previously taken weeks of the antibiotic, your particular bug may already be primed to resist it. Not until you have to rush to the hospital will anyone know that something has gone horribly wrong. And the resistant microbes can spread to others. (7)Indeed, antibiotic resistance is one of the world甜甜的爱情故事’s most pressing public-health problems. A single ca of so-called multidrug-resistant tuberculosis costs more than $250,000 to cure—and the deadly germs are on the ri in many countries. Up to 30% of bacteria that cau ear infections and pneumonia in the U.S. can fight off standard antibiotics. The toll: thousands of hospitalizations and billions of dollars a year. (8)The quinolone drugs—of which Cipro is one example—were once part of the solution. They kill a wide spectrum of bugs, including strains resistant to other drugs. But resistance to quinolones has appeare
