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.

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,switched以及动词原形derive,maintain,participate可以直接排除,expresses“表达”和pro—vides“提供”均不符合题意,也可以排除。
