北京地区企业管理本科学士学位英语考试内容提要:
Questions I to 5 are based on the following passage:
Spending 50 minutes with a cell phone close to your ear is enough to change brain cell activity in the part of the brain closest to the antenna(天线). But whether that causes any harm is not clear, scientists at the National Institute of Health said at a conference last month, adding that the study will not likely settle concerns of a link between cell phones and brain cancer. “What we showed is glucose (葡萄糖) metabolism(代谢)(a sign of brain activity) increases in the brain in people who were exposed to a cell phone in the area closest to the antenna,” said Dr. Nora Volkow of the NIH, whose study was published in the Journal of the American Medical Association. (76) The study was meant to examine how the brain reacts to electromagnetic fields caused by wireless phone signals。
