这个作业怎么做？阅读理解

阅读理解 Do you want to improve your memory?Are you struggling to remember names and faces as you get older?Try picking up the phone and speaking to someone.Scientists have found that holding a simple conversation could be just as effective as playing popular 'braintraining' games that have reproduced a multimillion pound industry. Researchers compared 36 studies on memory exercises performed between 1970 and 2007.Some studies suggested both healthy older adults and those with mild cognitive impairment (轻度认知缺陷) could remember words better after some memory training. However,other studies found this improvement was matched by those who were asked to hold a discussion about art. The finding that social interaction could be just as effective at keeping memory loss at bay comes after Age Concern warned more than a million people aged over 65 lived alone in their own homes.The charity warned solitary lifestyles were a 'silent epidemic (静默的流行病)'spreading through the nation quickly. Dr Martin said most people experienced a cognitive decline in old age.This can include memory loss and inability to plan,pay close attention or perform tasks as quickly as before.The normal rate of decline seems to speed up in some people,leading to a condition called mild cognitive impairment,which some researchers see as a reason for developing mental diseases later in life. Although several studies have suggested that braintraining exercises could delay signs of cognitive decline,the studies and the types of training have many different kinds.The findings do not mean that longer,more intense or different exercises might not be effective,but that those which have been reported thus far have only limited effect. Dr Martin concluded researchers needed to improve the way they used their studies to eventually determine ways of preventing cognitive decline in old age. 1．What is the main idea of Paragraph 1?
