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
A
解析
空格前面为be动词的否定形式isn’t,后面为介词on,因此空格处需要填入形容词,充当表语。本句的主语为evidence“证据”,想要表达的意思是关于后面提到的问题证据尚不确凿或者尚不充分,因此空格处应填入表示“确凿的,毫无疑问的”等意义的形容词,由此确定形容词conclusive为本题答案。备选词语中只有两个形容词,particular意为“特别的”,与此处要表达的意义不符,可以排除。
