Questions 47 to 56 are based on the following passage.
So many people use the cell phone so frequently every day. But 47 little is certain about the health effects of its use. Manufacturers 48 that cell phones meet government standards for safe radio-frequency radiation emission, but enough studies are beginning to document a possible 49 in rate brain tumors (肿瘤), headaches and behavioral disorders in children to cause concern. So far, the evidence isn’t 50 on whether the use of cell phone 51 to any increased risk of cancer. In a new trial, researchers asked 47 volunteers to 52 in a project to measure glucose (葡萄糖) consumption in the brain by scanning the brain to see how sells use energy. For both 50-minute scans, the volunteers had a cell phone 53 to each ear. During the first scan, the devices were turned off, but for the second scan, the phone on the right ear was 54 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 55 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 56 a whole new avenue for scientific inquiry, though it doesn’t say anything about whether cell-phone radiation can cause cancer.

Passage One
Questions 57 to 61 are based on the following passage.
It’s no secret that some of the resolutions that many of us vowed to pursue in the new year— eat healthy, lose weight, quit smoking, save more money — have already fallen by the wayside.
Many of them are likely the same resolutions that we abandoned last January. And it’s a good thing for whose who sell health club memberships, quit-smoking programs and other products that help us think we can improve our lives.
Many gyms see new memberships double in January, making up for the third of their members who do not renew each year.
And many who sign up in January will be no-shows by February.
“If I try one quick fix and it doesn’t work, I may be more likely to try the next quick fix,” Lisa Lahey, who coaches executives how to sustain behavior change, told The Times.
The Biggest Loser Resort at Fitness Ridge doesn’t offer any quick fixes, just a 12-hour schedule full of exercise, a 1,200-calories-a-day diet and a fee of $2,000 a week. The resort teaches its clients that “weight management” is a combination of fitness, diet and emotional health.
“Given my recent weight gain, and the fact that I was turning 50,” Jennifer Conlin wrote in The Time, “ I wanted to start a program that would make 2012 the year I finally got in shape.”
“For years, the advice to eh overweight people has been that we simply need to eat less ad exercise more,” Tara Parker-Pope wrote. “While there is truth to this guidance, it fails to take into account that the human body continues to fight against weight loss long after dieting has stopped. This translates into a sobering (令人清醒的) reality: once we become fat, most of us, despite out best efforts, will probably stay fat.”
Of course this revelation (揭示), if proven true by further study, is not good news for the weight-loss industry. But chances are it won’t have much impact on the human tendency to resolve to get to the gym more and avoid chocolate cake when the clock strikes midnight on December 31.
