第4、5、6、7、8题: High Stress May Damage Memory According to a report issued in May 1998,elderly people who consistently high blood levels of the stress hormone. What'smore ,high levels of cortisol are also associated with shrinking of thehippocampus(海马区), a region of the brain that plays akey role in learning and memory. The findings suggest that even cortisol levelsin the normal, "healthy" range can actually accelerate brain aging. The study results "now provide substantialevidence that long-term exposure to adrenal(肾上腺) stresshormones may promote hippocampal aging in normal elderly humans, "writeNada porter and Phillip Landfield. Cortisol is a hormone releases in responseto stress by the adrenal glands(腺), which sit on top ofthe kidneys (肾). Over a 5-to 6-year period, dr. Sonia lupine andhis colleagues measures 24-hour cortisol levels in 51 healthy volunteers, mostwhom were in their 70s. The researchers tested the volunteers' memoryon six people in the increasing/high category and five people in thedecreasing/moderate group. The groups did not differ in tests of immediatememory, but the increasing/high cortisol group had other memory problems comparedwith those in the decreasing/moderate group. The researchers also found that the totalvolume of the hippocampus in those in the increasing/high group was 14% lowerthan those in the decreasing/moderate group, although there were no differencesin other brain regions. The results suggest that "…brain aging can be accelerated by levels of adrenal hormones thatare not generally regarded as pathological(病态的) andthat variation within this normal range is related to variation in the rate ofbrain aging." write porter and landfield." This further suggests thatchronic stress may accelerate the worsening of the hippocampus. 6 which of the following plays a key role inone's learning and memory? A the kidneys B the adrenal hormone C the stress hormone D the hippocampus 7 when the levels of cortisol go high ,thehippocampus A may expand B may shrink C may disappear D may function better 8 according to the passage, when people areunder stress, A the adrenal glands will produce cortisol B the kidneys will shrink rapidly C the hippocampus will produce cortisol D the brain will work more efficiently 9 it app ears that when the hippocampus shrinkssue to high levels of cortisol, other brain regions A may change dramatically B may stop functioning C may remain unaffected D may be seriously damaged 10 the research conducted by porter and landfield showed that A the levels of adrenal hormones have nothingto do with brain aging B changes in the levels of adrenal hormones canaffect brain aging C chronic stress may strengthen one's memory D the rate of brain aging always remains stable |

A team of scientists from the Karolinska Institute in Sweden looked _____2 the effect of physical activity and cancer risk in 40,708 men _____3 between 45 and 79. The seven-year study found that men _____4 walked or cycled for at least 30 minutes a day had a 34 per cent lower risk of _____5 from cancer than the men who did less exercise or nothing at all _____6 . the period studied, 3,714 men developed cancer and 1,153 died from the disease. The researchers suggest that half an hour’s walking _____ 7 cycling a day increased survival among these men by 33 per cent. The researchers surveyed men from two counties in central Sweden about their lifestyle and the amount of_____ 8 activity they were usually doing. They then scored these responses and compared the results _____ 9 data on cancer diagnosis and death officially recorded in a central cancer registry2 over a seven-year period. Lead author, Professor Alicja Wolk, said: "These results clearly show for the first time the effect that very simple and basic daily _____ 10 such as walking or cycling has in reducing cancer death risk in middle-aged and elderly _____ 11 " Dr Lesley Walker, director of cancer information at Cancer Research UK, said: "This study gives us a clear indication that men who exercise are less _____12 to die from cancer, and that they are more likely to_____ 13 the disease if they get it. It’s not entirely clear from this study what role exercise plays in preventing _____14 in men, but we do know that a healthy lifestyle can prevent up to half of all cancers- and _____15 exercise forms a key part of this." 练习: 1.
