Unit 2 CloningⅠ. 细品味经典文章(2020·浙江高考) Challenging work that requires lots of analytical thinking, planning and other managerial skills might help your brain stay sharp as you age, a study published Wednesday in the journal Neurology suggests.Researchers from the University of Leipzig in Germany gathered more than 1, 000 retired workers who were over age 75 and assessed the volunteers’ memory and thinking skills through a battery of tests. Then, for eight years, the scientists asked the same group to e back to the lab every 18 months to take the same sorts of tests.Those who had held mentally stimulating (刺激) , demanding jobs before retirement tended to do the best on the tests. And they tended to lose cognitive (认知) function at a much slower rate than those with the least mentally challenging jobs. The results held true even after the scientists accounted for the participants’overall health status.“This works just like physical exercise, ” says Francisca Then, who led the study. “After a long r un, you may feel like you’re in pain, you may feel tired. But it makes you fit. After a long day at work—sure, you will feel tired, but it can help your brain stay healthy. ”It’s not just corporate jobs, or even paid work that can help keep your brain fit, Then points out. A waiter’s job, for example, that requires multitasking, teamwork and decisionmaking could be just as stimulating as any highlevel office work. And “running a family household requires highlevel planning and coordinating (协调), ”she says. “You have to organize the activities of the children and take care of the bills and groceries. ”Of course, our brains can decline as we grow older for lots of reasons including other environmental influences or genetic factors. Still, continuing to challenge yourself mentally and keeping your mind busy can only help.Ⅱ. 按要求完成任务1. 写出文章中与本单元话题有关的单词和短语。
