So far, the evidence isn’t (4) on whether the use of cell phones (5) to any increased risk of cancer. In a new trial, researchers asked 47 volunteers to (6) 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 (7) to each ear. During the first scan, the devices were turned off, but for the second scan, the phone on the right ear was (8) 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 (9) 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 (10) a whole new avenue for scientific inquiry, though it doesn’t say anything about whether cell-phone radiation can cause cancer.A.conclusiveB.contributesC.deriveD.expressesE.fixedF.immenselyG.increaseH.maintainI.missionJ.participateK.particularL.providesM.regionsN.surprisinglyO.switched (5)处应填()
