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.

答案
H
解析
空格前面是名词Manufacturers,后面是连词that引导的宾语从句,因此空格处需要填入句子的谓语动词。前文中提到了使用手机对身体健康的影响几乎毫无定论,后面的that从句提到手机符合政府关于无线电频率辐射排放的安伞标准,这很显然是手机制造商的态度和观点。因此,空格处需要填入一个表达态度和观点的动词,由此确定动词为本题答案,意为“坚持认为”备选词语中有八个动词,根据主语的形式空格处需要填入动词原形,因此第三人称单数形式contributes,expresses,以及过去分词fixed,switched可以直接排除,derive“源自”,participate“参加”,均不符合题意。
