(43)B gradually,"Gold said."Seniors are(44)C longer,and that's a good thing,but it's only a good thing(45)D a certain degree that their brains are(46)B."
Gold's team compared task-switching of younger and older(47)A,knowing they would find slower speeds in the(48)C population because of previous studies.(49)D,they found that older adults who spoke two languages were able to switch mental gear (齿轮)(50)A than those who didn't.
First,Gold and his team(51)B 30 people,who were either bilingual (双语的)(52)C monolingual (单语的),to look at a series of colored shapes and(53)D with the name of each shape by pushing a button.Then,they(54)A the participants with a similar series of colored shapes and asked them to respond with what(55)Cthe shapes were by pushing a button.The bilingual people had the(56)Bto respond faster to the shifting prompts (提示).
Researchers then gathered 80 more people for a second(57)A; 40bilinguals and 40monolinguals.This time,researchers used FMRI machines to(58)D brain activity during the same shape-and color-identifying(59)C.Gold and his team found that bilingual people had different brain activity than their monolingual peers.
"Learning a second language in childhood was thought of as(60)A,"Gold said."Actually,it's beneficial."
