    Improve Your Memory

    To many people advancing age means losing your hair,your waistline and your memory.But is it an inescapable fact that the older you get,the less you remember? Well,as time goes by,we tend to blame age for problems that are not necessarily age-related.
    When a teenager can't find her keys,she thinks it's because she's distracted or disorganized, but a 70-year-old blames her memory. In fact,the 70-year-old may have been misplacing things for decades一like we all do from time to time.
    In healthy people,memory doesn't deteriorate as quickly as many of us think. According to psychologists,as we age,our memory mechanism isn't broken,it's just different.The brain's processing time slows down over the years,though no one knows exactly why.Recent research suggests that nerve cells lose efficiency and that there's less activity in the part of the brain that decides whether to store information or not.But it's not clear that less activity is worse.A beginning athlete is winded. more easily than a trained athlete.In the same way,as the brain gets more skilled at a task,it spends less energy on it.
    There are steps you can take to improve your memory,though you have to work to keep your brain in shape.It's like having a good body. You can't go to the gym once a year and expect to stay in top form.
    Some memory enhancement experts suggest using the AM principle.Pay attention to what you want to remember. Then give some meaning to it. We remember things when we focus on them, whether we intend to or not. That helps explain why jingles stick in our minds.They are played on loud,flashy TV commercials.They also use rhyme and music to help us remember better.
    Basic organization helps us remember the boring stuff. For example,rather than trying to recall a random list of groceries,we can divide them into categories,such as dairy,meat and produce. For important things like keys and money,we can set up a"forget-me-not"spot where we always keep them.
    We can also eat to aid our memory power. Whole grains,fruits and vegetables are excellent sources of glucose,the brain's preferred fuel. Another low-tech way to improve memory is to get adequate rest. Sleep may allow our brain time to encode memories.
    Interest in friends,family and hobbies does wonders for our memory.A sense of passion or purpose helps us remember. Memory requires us to pay attention to our lives,allowing us to discover in them everything worth remembering.

    It can be inferred from the passage that memory problems are not really age-related.
    A:Right
    B:Wrong
    C:Not mentioned

    答案:B
    解析:
    本题给出的信息是正确的。依据是第一段第三句中提到“Well, as time goes by, we tend to blame age for problems that are not necessarily age-related.”其实,随着时间的流逝,我们会将一些不一定与年龄相关的问题归咎于年龄。题干中描述的“你年纪越大,记得就越少,这不总是正确的”与原文意思相符,所以选A。
    本题给出的信息是错误的。依据的信息句和上题信息句相同。题干所描述的“我们可以推理出记忆力的问题不是真的和年龄相关”,与原文不相符,因为“not necessarily”指“不一定”,而不是指“not really"(不是真的)。
    本题给出的信息是错误的。依据是第三段第二句:"According to psychologists, as we age, our memory mechanism isn't broken, it's just different.”据心理学家说,当我们变老时,我们的记忆机能不会失效,只是变得和以前不一样了。题干中所陈述的“当我们变老,我们的记忆机能失效,所以它就和以前不一样了”,这个说法与原文恰恰相反,所以选B。
    文章没有谈到这方面的信息。
    本题给出的信息是正确的。依据是第四段:"There are steps you can take to improve your memory,though you have to work to keep your brain in shape .It's like having a good body.You can't go to the gym once a year and expect to stay in top form.”虽然你工作以使你的大脑保持良好状态,但也有一些步骤可以用来提高记忆力。就像拥有一个好身体一样,你不能每年只去一次健身房还期望自己处于巅峰状态。题干陈述“你必须工作以使你的大脑保持灵活,就如同你努力运动使你保持体形一样”,这与原文意思相符,所以选A。
    本题给出的信息是错误的。依据是第五段第二、三句:"Pay attention to what you want to remember.Then give some meaning to it.”关注你想要记忆的东西,并且给它以某种意义。依此推出AM代表的意思应为“attention and meaning"。而题干中说的是“注意力和记忆”与原文不符,所以选B。
    本题给出的信息是正确的。依据是倒数第二段的第一句和第三句:"We can also eat to aid our memory power.”我们还可以通过饮食来帮助我们提高记忆力。"Another low-tech way to improve memory is to get adequate rest.”另外一种低科技的提高记忆力的方法就是要有足够的休息。题干中陈述“对食物正确的选择和大量的休息对记忆有益”,这与原文意思相符,所以选A。
