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
J
解析
空格前面为to,后面为介词in,而且与to搭配的是动词asked,构成ask sb.to do sth.结构,意为“要求某人做某事,让某人做某事”,因此空格处需要填入动词。本句的意思是在一项新的研究中,研究专家找到了47名志愿者参与到一项实验项目中,通过扫描大脑进而对细胞如何消耗能量进行观察,以测定大脑中葡萄糖的消耗情况,因此空格处应填入一个表示“参与,参加”的动词,而且需要与介词in进行搭配,由此确定动词participate为本题答案,意为“参加”。此处需要填入的是动词原形,因此第三人称单数的动词contributes,expresses,provides,以及过去分词fixed,swished可以直接排除,derive“剥夺”和maintain“坚持认为”均不符合题意,也可以排除。
