So many people use the cell phone so frequently every day. But【S1】______little is certain about the health effects of its use. Manufacturers【S2】______that cell phones meet government standards for safe radio-frequency radiation emission, but enough studies are beginning to document a possible【S3】______in rare brain tumors (肿瘤), headaches and behavioral disorders in children to cause concern. So far, the evidence isn’t【S4】______on whether the use of cell phones【S5】______to any increased risk of cancer. In a new trial, researchers asked 47 volunteers to【S6】______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【S7】______to each ear. During the first scan, the devices were turned off, but for the second scan, the phone on the right ear was【S8】______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【S9】______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【S10】______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
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。
