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.
A) conclusive I) mission
B) contributes J) participate
C) derive K) particular
D) expresses L) provides
E) fixed M) regions
F) immensely N) surprisingly
G) increase O) switched
H) maintain
【S10】
选项
答案
L
解析
空格前面为连词and,后面为名词短语,通过对句子结构的分析,空格处缺少的成分是与shows构成并列谓语的动词。文章结尾处对实验结果进行总结,这项研究既证实了手机能够改变大脑的活动,也为进一步的科学研究提供了一个全新的思路。因此,空格处应填入表示“提供”的动词,并且需要与后面的介词for进行搭配,由此可以断定provides为本题答案,provides…for…意为“为……提供……”。根据句子的主语和时态,空格处需要填入的是动词第三人称单数形式,因此动词原形derive,maintain,participate以及过去分词fixed,switched可以直接排除,contributes“促成,造成”和expresses“表达”均不符合句意,也可以排除。
