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.

       A．Cell phone may do harm to our health if we hold it against our ear or store in our pocket

Stepping into a pool of water is common enough, but who could ever imagine stepping into a pool of fish? In February of 1974, Bill Tapp, an Australian farmer, saw a rain of fish that covered his farm. How surprised he must have been when he heard many fish hitting against his roof!

　　 What caused this strange occurrence? This is a question that had long puzzled people who study fish. The answer turned out to be a combination of wind and storm.

　　When it is spring in the northern part of the world, it is fall in Australia. Throughout the autumn season, terrible storms arise and rains flood the land. The strong winds sweep over Australia like huge vacuum cleaners, collecting seaweed, pieces of wood, and even schools of fish. Strong winds may carry these bits of nature for many miles before dropping them on fields, houses, and astonished people.

　　Although they seem unusual, fish-falls occur quite frequently in Australia. When Bill Tapp was asked to describe the scene of fish, he remarked, “They look like millions of dead birds falling down.” His statement is not surprising. The wonders of the natural world are as common as rain. Nature, with its infinite wonders, can create waterfalls that flow upward and fish that fall out of the sky.

　　56. What is this passage about?

　　A. A sad story. 　　　　　　　　　　　　B. A rain of fish.

　　C. Australia’s northern part.　　　　　D. The damage done by floods.

　　57. Fish-falls occur in Australia_________ .

　　A. quite often 　　　　　　B. on large farms

　　C. only in winter　　　　　D. when the air is calm

　　58. It is a known fact that ________.

　　A. one should watch where one steps

　　B. Bill Tapp is a scientist who studies farming

　　C. the natural world can never create waterfalls that fall upward

　　D. the seasons in the southern part are different from those in the northern part

 　59. The word “infinite” is closest in meaning to _________.

　　A. easy 　　　B. difficult 　　　C. countless 　　　D. dangerous

Beauty has always been regarded as something praiseworthy. Almost everyone thinks attractive people are happier and healthier, have better marriages and have more respectable jobs. Personal advisors give them better advice for finding jobs. Even judges are softer on attractive defendants. But in the executive（主管的） circle, beauty can become a liability.

　　While attractiveness is a positive factor for a man on his way up the executive ladder, it is harmful to a woman.

　　Handsome male executives were considered having more honesty than plainer men; effort and ability were thought to lead to their success.

　　Attractive female executives were considered to have less honesty than unattractive ones; their success was connected not with ability but with factors such as luck.

　　All unattractive women executives were thought to have more honesty and to be more capable than the attractive female executives. Interestingly, though, the rise of the unattractive overnight successes was connected more to personal relationships and less to ability than that of the attractive overnight successes.

　　Why are attractive women not thought to be able? An attractive woman is considered to be more feminine has an advantage in traditionally female jobs, but an attractive woman in a traditionally manly position appears to lack the "manly"qualifies required.

　　This is true even in politics, "When the only clue is how he or she looks, people treat men and women differently, " says Anne Bowman, who recently published a study on the effects of attractiveness on political candidates（候选人）. She asked 125 undergraduate students to rank two groups of photographs, one of men and one of women, in order of attractiveness. The students were told the photographs were of candidates for political offices. They were asked to rank them again, in the order they would vote for them.

　　The results showed that attractive males completely defeated unattractive men, but the women who had ranked most attractive unchangeably received the fewest votes.

　　The word "liability" most probably means ________.

　　A. disadvantage　B. advantage　　　C. misfortune　　 D. trouble

　Bowman's experiment shows that when it comes to politics, attractiveness________

　　A. turns out to　be a disadvantage to men

　　B. is more of a disadvantage than an advantage to women

　　C. has as little effect on men as on women

　　D. affects men and women alike

　　It can be inferred from the passage that people's views on beauty are often________.

　　A. practical　　　B. supportive　　 C. old - fashioned　D. one - sided

　　The author writes this passage to ________.

　　A. give advice to job - seekers who are attractive

　　B. discuss the disadvantages of being attractive

　　C. demand equal rights for women

　　D. state the importance of appearance
