So many people use the cell phone so frequently every day. But【C6】________little is certain about the health effects of its use. Manufacturers【C7】________that cell phones meet government standards for safe radio frequency radiation emission, but enough studies are beginning to document a possible【C8】________in rare brain tumors (肿瘤), headaches and behavioral disorders in children to-cause concern. So far, the evidence isn’t【C9】________on whether the use of cell phones【C10】________ to any increased risk of cancer. In a new trial, researchers asked 47 volunteers to【C11】________in a project to measure glucose(葡萄糖) consumption in the brain by scanning the brain to see how cells use energy. For both 50 minute scans, the volunteers had a cell phone【C12】________to each ear.
During the first scan, the devices were turned off but for the second scan, the phone on the right ear was【C13】________on and received a recorded message call, although the volume was muted (消音) so the noise wouldn’t bias the results. The results of the second scan showed that the【C14】________ of the brain nearest to the device had higher rates of glucose consumption than the rest of the brain. The study shows that cell phones can change brain activity, and【C15】________a whole new avenue for scientific inquiry, though it doesn’t say anything about whether cell phone radiation can cause cancer.

【C10】
选项
答案
B
解析
空格前面为名词短语the use of cell phones, 后面为介词to, 因此空格处需要填入充当谓语的动词。空格位于whether引导的从句中, 从句要表达的意思是手机的使用是否会增加患癌症的风险, 因此空格处应填入一个表示“造成, 导致”意思的动词, 并且需要与介词to搭配, 由此确定contributes为本题答案, 意为“促成, 造成”。根据从句的主语, 此处需要填入的是第三人称单数形式的动词, 因此过去分词fixed, swished以及动词原形derive, maintain, participate可以直接排除, expresses“表达”和provides“提供”均不符合题意, 也可以排除。
