Holding a cell phone against your ear or stalling it in your pocket may be hazardous to your health．
This paraphrases a warning that cell phone; manufacturers include in the small print that is often tossed aside when a new phone is purchased．Apple, for example, doesn't want iP hones to come closer to you than 1．5 centimeters; Research In Motion, Blackberry's manufacturer, recommends 2.5 centimeters．
If health issues arise from cell phone use, the implications are huge．Voice calls - Americans chat on cell phones 2．26 trillion minutes annually - generate $109 billion for the wireless carriers．
Devra Davis, an epidemiologist who has worked for the University of Pittsburgh, has published a book about cell phone radiation, "Disconnect." The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
"Most cancers have multiple causes," she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid. No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiofrequency radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone's speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen.
We can infer from the passage that________．
A．Cell phone may do harm to our health if we hold it against our ear or store in our pocket
B．Devra Davis thinks that there are many factors contributing to cancer．
C．The increase in brain cancer in the young adults may have something to do with cell phone
D．Children are more likely to be affected by radiation
According to the passage, how could children avoid being hurt by cell phone radiation?
A．They can keep cell phones away from the abdomen．
B．They can send short massage instead of making phone calls directly．
C．They can pay more attention to the small print on the phone．
D．They should use more advanced cell phones．
From this passage we can learn that．________．
A．American cell phone manufacturers did not give any warning to their customers
B．American cell phone manufacturers benefit greatly from their products
C．Scientists have found the connection between brain cancer and ceil phone
D．Cell phone should be banned because of the increase in brain cancer

We were on tour a few summers ago, driving through Chicago, when right outside of the city, we got pulled over(被迫停车). A middle-aged policeman came up to the ear and was really being troublesome at first. He said, "You were speeding. Where are you going in such a hurry?" Our guitarist, Tim, told him that we were on our way to Wisconsin to play a show. Then his way towards us totally changed. He asked, "Oh, so you boys are in a band?" We told him that we were. He then asked all the usual band questions about the type of music we played, and how long we had been at it.
Suddenly, he stopped and said, "Tim, you want to get out of this ticket, don't you?" Tim said, "Yes. " So the officer asked him to step out of the car. The rest of us, inside the car, didn' t know what to think as we watched the policeman talk to Tim. Then the policeman put Tim in the back of the police car and threw the car into reverse(倒车), stopping a few feet in back of our car.
Now we suddenly felt frightened. We didn't know if we were all going to prison. Suddenly, the policeman's voice came over in a loudspeaker. He said, "Ladies and gentlemen, for the first time ever, we have Tim here singing on Route 90." Later we knew, the policeman had told Tim that if he sang one of our songs over the loudspeaker in the police car, we would get out of the ticket. Seconds later, Tim started screaming into the receiver. The policeman enjoyed the performance, and sent us on our way without a ticket.
