Women，drinking three or more cups of coffee a day，were 30percent less likely to have memory decline at age 65than those drinking one cup or less daily．And the benefit increased with age．Women over age 80who drank three or more cups of coffee a day were about 70percent less likely to have memory decline than those who drank one cup or less，the researchers said．Caffeinated tea had the same effect in the women，the study found，although more was needed to get the same caffeine boost．"Count roughly two cups of tea for a cup of coffee，"said study leader Karen Ritchie of INSERM，the French National Institute for Health and Medical Research．But the researchers didn't find a similarly protective effect in men，although other studies have found a benefit to males．How might caffeine help ward off cognitive decline？"It is a cognitive stimulant．"said Ritchie．It also helps to reduce levels of the protein called beta amyloid in the brain，she said，"whose accumulation is responsible for Alzheimer's disease but which also occurs in normal aging．"Ritchie said she wasn't sure why men in the study didn't benefit from caffeine．"Our hypothesis is that either women metabolize caffeine differently than men，or there may be an interaction of the caffeine with the sex hormones，the estrogen-progesterone balance，"she said．The French study confirms previous research，said William Scott，professor of medicine at the University of Miami Miller School of Medicine，who has researched caffeine's beneficial effects against Parkinson's disease，also a neurodegenerative disorder．As for caffeine only protecting women，Scott noted that just 2，800of the 7，000study participants were men，and the results might have differed if more men were included．A study published in February in the European Journal of Clinical Nutrition looked at 676healthy men and found that regular coffee drinkers had a lower rate of cognitive decline over a 10-year follow-up than those who didn't drink coffee．Those who drank three cups daily had the least signs of decline．Both Scott and Ritchie agreed that more study is needed．Ritchie's research will next look at the relationship between caffeine and Alzheimer's．70．As it is indicated in the 1st paragraph，how does coffee influence women's memory？ ____ A．The older the woman was，the more slowly her memory declined．B．The more coffee the woman drank，the more slowly her memory declined．C．The older the woman was，the more remarkable her memory was．D．The more coffee the woman drank，the more remarkable her memory was．71．What is true about caffeinated tea？ ____ A．It affected women's memory in the same manner as coffee．B．It influenced women's memory as effectively as coffee．C．It boosted women's memory in the same rate as coffee．D．It contained the same amount of caffeine as coffee．72．According to Ritchie．Alzheimer's disease is resulted from ____ ．A．the lack of caffeine in the brainB．the accumulation of beta amyloidC．high level of proteins in the brainD．abnormal metabolism in normal aging73．William Scott would most probably agree that caffeine helped ____ ．A．reduce the risk of Alzheimer's diseaseB．protect both men and women from diseasesC．balance the production of female hormonesD．delay the process of cognitive decline．

Women，drinking three or more cups of coffee a day，were 30percent less likely to have memory decline at age 65than those drinking one cup or less daily．And the benefit increased with age．Women over age 80who drank three or more cups of coffee a day were about 70percent less likely to have memory decline than those who drank one cup or less，the researchers said．
Caffeinated tea had the same effect in the women，the study found，although more was needed to get the same caffeine boost．"Count roughly two cups of tea for a cup of coffee，"said study leader Karen Ritchie of INSERM，the French National Institute for Health and Medical Research．
But the researchers didn't find a similarly protective effect in men，although other studies have found a benefit to males．
How might caffeine help ward off cognitive decline？"It is a cognitive stimulant．"said Ritchie．It also helps to reduce levels of the protein called beta amyloid in the brain，she said，"whose accumulation is responsible for Alzheimer's disease but which also occurs in normal aging．"
Ritchie said she wasn't sure why men in the study didn't benefit from caffeine．"Our hypothesis is that either women metabolize caffeine differently than men，or there may be an interaction of the caffeine with the sex hormones，the estrogen-progesterone balance，"she said．
The French study confirms previous research，said William Scott，professor of medicine at the University of Miami Miller School of Medicine，who has researched caffeine's beneficial effects against Parkinson's disease，also a neurodegenerative disorder．
As for caffeine only protecting women，Scott noted that just 2，800of the 7，000study participants were men，and the results might have differed if more men were included．
A study published in February in the European Journal of Clinical Nutrition looked at 676healthy men and found that regular coffee drinkers had a lower rate of cognitive decline over a 10-year follow-up than those who didn't drink coffee．Those who drank three cups daily had the least signs of decline．
Both Scott and Ritchie agreed that more study is needed．Ritchie's research will next look at the relationship between caffeine and Alzheimer's．
70．As it is indicated in the 1st paragraph，how does coffee influence women's memory？ ____
A．The older the woman was，the more slowly her memory declined．
B．The more coffee the woman drank，the more slowly her memory declined．
C．The older the woman was，the more remarkable her memory was．
D．The more coffee the woman drank，the more remarkable her memory was．
71．What is true about caffeinated tea？ ____
A．It affected women's memory in the same manner as coffee．

C．It boosted women's memory in the same rate as coffee．
D．It contained the same amount of caffeine as coffee．
72．According to Ritchie．Alzheimer's disease is resulted from ____ ．

B．the accumulation of beta amyloid
C．high level of proteins in the brain
D．abnormal metabolism in normal aging
