So many people use the cell phone so frequently every day. But【C1】______little is certain about the health effects of its use. Manufacturers【C2】______that cell phones meet government standards for safe radio frequency radiation emission, but enough studies are beginning to document a possible【C3】______in rare brain tumors(肿瘤), headaches and behavioral disorders in children to cause concern. So far, the evidence isn’ t【C4】______on whether the use of cell phones【C5】______to any increased risk of cancer. In a new trial, researchers asked 47 volunteers to【C6】______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【C7】______to each ear. During the first scan, the devices were turned off but for the second scan, the phone on the right ear was【C8】______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【C9】______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【C10】______a whole new avenue for scientific inquiry, though it doesn’ t say anything about whether cell phone radiation can cause cancer.

【C9】
选项
答案
M
解析
通过分析句子结构可以判断,空格处缺少的成分为宾语从句的主语,空格后为介词of,因此,空格处需要填入名词,充当主语和of the brain的中心词。本句的大意是,第二次扫描的结果显示,最靠近装置的大脑区域中葡萄糖的消耗量要远远高于大脑巾的其他区域。因此,空格处需要填入的是表示“区域”的名词,南此可以确定名词regions为本题答案,意为“区域,地区”。备选词语中有三个名词,increase“增加”和mission“任务”均与此处要表达的意义不符,可以排除。
