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 (脑瘤), 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 censure 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 activities and【C10】______a whole new avenue for scientific inquiry, though it doesn’t say anything about whether cell-phone radiation can cause cancer.
A) conclusive B) contributes C) derive D) expresses
E) fixed F) immensely G) increase H) maintain
I) mission J) participate K) particular L) provides
M) regions N) surprisingly O) switched [br] 【C2】
选项
答案
H
解析
空格前为一个名词,空格后为一个从句,显然空格处应填一个动词。从句提到“手机符合政府规定的安全辐射要求”,这应该是manufacturers“制造商”的说法。H)maintain意思为“坚持说”,D)expresses“表达”,都符合句意。但manufacturers是复数,所以排除D。
