Warning: Holding a cell phone against your ear or storing 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【C1】______ when a new phone is purchased. Apple, 【C2】______, doesn’t want iPhones to come closer to you than 1.5 centimeters; Research In Motion, BlackBerry’s manufacturer,【C3】______2.5 centimeters.
If health issues【C4】______cell phone use, the implications are huge. According to a recent survey,Americans chat【C5】______cell phones 2.26 trillion minutes annually, which【C6】______ $100 billion for the wireless carriers. Epidemiologists(流行病学家)pointed out that brain cancer is a( n) 【C7】______. Overall, there has not been a(n) 【C8】______ in its incidence since cell phones arrived. But the average【C9】______an increase in brain cancer in the 20-to-29 age group【C10】______a drop for the older population.
"Most cancers have【C11】______causes," an expert says,【C12】______she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Besides, children are more【C13】______ to radiation than adults, other scientists point out. Radiation that【C14】______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【C15】______ more absorptive fluid.
Henry Lai ,a research professor at the University of Washington,began laboratory radiation studies in 1980 and found that rats【C16】______ radio frequency radiation had【C17】______DNA in their brains.
Ms. Davis recommends【C18】______wired headsets or the phone’s speaker. Children should text【C19】______ call, she said, and pregnant women should keep phones away from the abdomen【C20】______.
【C10】
选项
A、when
B、though
C、while
D、however
答案
C
解析
语篇衔接题。根据后面的单词drop可以判断,前后两个分句应该是转折关系,因此答案为[C]while,意为“然而,相反的是”。[A]when表示“与此同时”,与本句的逻辑关系不符;[B]though是一个从属连词,表示“虽然”,应该用来引导前面那个分句;[D]however是副词,不能放在两个句子之间进行连接,故上述三个选项均可排除。
