    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.

【C2】
选项 A、for example
B、such as
C、as a result
D、in fact
答案A
解析 语篇理解题。因为上面提到了手机生产商会在附属细则中提醒大家，所以下面提到著名手机生产商Apple，作者意在举例说明，因此应该选[A]for example。[B]such as虽然也是表示举例，但是一般跟在名词或动名词后面；[C]aus a result意为“因此，结果，所以”，表示结果；[D]in fact意为“实际上，事实上”，以上三项从意思和用法上都不符合要求，故排除。
