If you don’t have a college degree, you’re at greater risk of developing memory problems or even Alzheimer’s （老年痴呆）．Education plays a key role in lifelong memory performance and risk for mental disorder, and it's well documented that those with a college degree possess a cognitive（认知的） advantage over their less educated counterparts in middle and old age．
Now, a large national study from Brandeis University published in the American Journal of Geriatric Psychiatry shows that those with less schooling can significantly make up for poorer education by frequently engaging in mental exercises such as word games, puzzles, reading, and lectures．
“The lifelong benefits of higher education for memory in later life are quite impressive, but we do not clearly understand how and why these effects last so long,” said lead author Margie Lachman, a psychologist．She suggested that higher education may encourage lifelong interest in cognitive efforts, while those with less education may not engage as frequently in mental exercises that help keep the memory agile （敏捷地）．
But education early in adulthood does not appear to be the only route to maintain your memory．The study found that intellectual activities undertaken regularly made a difference．“Among individuals with low education, those who are engaged in reading, writing, attending lectures, doing word games or puzzles once a week or more had memory scores similar to people with more education,” said Lachman．
The study, called Midlife in the United States, assessed 3,343 men and women between the ages of 32 and 84 with a mean age of 56 years．Almost 40 percent of the participants had at least a 4-year college degree．The researchers evaluated how the participants performed in two cognitive areas, verbal memory and executive function --- brain processes involved in planning, abstract thinking and cognitive flexibility．Participants were given a battery of tests, including tests of verbal fluency, word recall, and backward counting．
As expected, those with higher education said they engaged in cognitive activities more often and also did better on the memory tests, but some with lower education also did well, explained Lachman．
“The findings are promising because they suggest there may be ways to level the playing field for those with lower educational achievement, and protect those at greatest risk for memory declines,” said Lachman．“Although we can not rule out the possibility that those who have better memories are the ones who take on more activities, the evidence is consistent with cognitive plasticity （可塑性）, and suggests some degree of personal control over cognitive functioning in adulthood by adopting an intellectually active lifestyle．”
57．What is the text mainly about?
A．Higher education has a better cognitive advantage．
B．Better memories result from college degree．
C．Cognitive activity does a mind good．
D．Poor education has more risk of memory declines．
58．According to the result of Margie Lachman’s study, we can conclude that ________．
A．education is responsible for the lifelong memory performance and risk for mental disorder
B．education early in adulthood can be the only route to maintain your memory
C．those with higher education did better on the memory tests than those with lower education
D．an intellectually active lifestyle does help to maintain your memory
59．What do we know about the study called Midlife?
A．Participants each were given a battery to test their memory．
B．The average age of the participants are 56 years old．
C．Participants had to perform in one of the two cognitive areas．
D．One in four of the participants had a 4-year college degree．
60．Why are the findings of the Lachman’s study promising?
A．The lower educated may have the same opportunities to keep up memory．
B．We may have ways to cure the people who have memory declines．
C．Adopting a different lifestyle can control over cognitive functioning．
D．We can find out the possibility to have better memories． 题型：未知 难度：其他题型

解析
略考点
据考高分专家说，试题“E If you don’t have .....”主要考查你对 [政治经济类阅读 ]考点的理解。政治经济类阅读
政治经济类文章的概念：
要做好这类阅读，平时就要注意了解国内外发生的政治经济大事，掌握一定背景知识，对这类文章的叙述特点及内容安排有一定了解，还要扩展这方面的词汇。阅读这类文章，要抓住文章的核心，即文章整体和各段主要在说什么，也要注意段落之间的逻辑关系。
如何备考政治经济类阅读理解题：
【题型说明】政治经济类阅读文章是高考常选材料之一。该类文章时代气息浓郁，语言鲜活，但熟字新义词、超纲词及专业词语多，长句、难句多。政治类文章大多数是同学们感性趣的内容，读起来倒有似曾相识的感觉，经济类文章读起来就像是雾里看花，文章看完，一头雾水。再加之这类文章的命题侧重于词义猜测、推理判断和文章主旨，同学们对这类题材是望而生畏。
【备考策略】建立心理优势。针对不同体裁的文章，我们要采取相应的阅读方法和技巧。政治类文章多采用记叙文形式，我们可采取“顺读法”，以便抓关键语句，领会文章主旨；而经济类文章则多采用说明文形式，我们则可以采取“逆读法”，先读试题，再从文章中查找有用信息。若遇到的确难读的材料。千万不用着急，因为你觉得难，其他人也一定是同感。在高考前，我们就要有这种心理准备，高考试卷肯定有一、两篇难以阅读的材料。不过，我们平时可以有意识地从报刊杂志上找一些较难的阅读材料来阅读，以培养自己迎难而上的心理素质。
【答题方法】
1、寻找主干：
根据英语中五种基本句型结构，把句子中的主语、谓语、宾语、表语等主要成分找出来，其他成分如定语、状语、补语等则易于理解。找到了句子主干，句子的意思至少明白了一半。
2、剔除从句：
在一个长句中可能会出现若干个从句，在理解时，如果把各个从句剔除出来单独理解，然后把大意拼凑起来，整个长句的意思就会明白六、七分。
3、辨别分句：
一个长句如果是由几个并列、转折、递进、对比关系的分句组成，句中往往有表示这些分句关系的连接词，只要能弄清楚分句和分句之间的逻辑关系，再把各层分句的意思加以连贯，整个长句的句意基本上能跃然脑中。
4、寻找关键词：
如果一个句子看完，一点句意的感觉也没有，下下策就是抓住句中的关键词，通过关键词大体弄懂这个长句的意思。
