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 phone【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.

答案
E
解析
通过分析句子,空格处与前面的动词had构成have sth.done的结构,因此空格处需要填入一个动词的过去分词。根据句意,志愿者们每只耳朵上各被安装一部手机。因此,空格处应填入表示“安装,固定”等意思的动词,并与空格后的介词to进行搭配,由此可以确定动词fixed为本题答案,意为“使固定,安装”。空格处需要填入动词过去分词形式,因此动词原形derive,maintain以及第三人称单数形式contributes,expresses,provides均可以直接排除,另一个过去分词switched意为“转换;改变”,与此处要表达的意思不符,也可以排除。
