    These Foods Help Improve Your Memory

    Though sleeping is the best way to enhance your memory,the foods in your diet also play a role in how your memory works.People care their diets in terms of whether it helps them build muscle or lose fat,but they neglect to think of how food can improve memory.
    In addition to eating memory foods,right meal amount plays an important role in how well your memory functions.Too little food will cause you to be distracted by hunger,while too much of it will make you sleepy.Incorporating the right memory foods and proper portion sizes will give you maximum results.
    Here are some of the memory foods that you should incorporate into your diet to reap the benefits of memory enhancement.
    Salmon
    As far as the protein is concerned,one of the best sources is salmon,for it is a good source of
    omega-3 fatty acids,which are essential for brain function and development. Studies have suggested that supplementing with DHA,which is found in fish oil,is beneficial for the development and maintenance of memory performance.
    Sunflower seeds
    Nuts have been regarded as a great way to get healthy fats into your diet,but many people forget that seeds fall into this category too.Sunflower seeds are a rich source of vitamin E,with one ounce providing 30%of your total daily intake.Vitamin E is one of the primary antioxidants that helps decrease the decline of memory as you get old,making it one nutrient you'll want to be sure to consume.
    Other sources of vitamin E include wheat germ oil,dry almond,safflower oil,hazelnut,peanut butter, spinach, broccoli, kiwi, and mango.
    Blueberries
    While all berries provide a number of health-related benefits,blueberries in particular area memory-boosting powerhouse.They are considered a memo汀food because they contain a phytochemical that is especially important in reversing the age-related decline of memory，while having a positive influence on spatial working memory．
    Besides,blueberries rank low on the glycemic（血糖）index scale,making them a good fruit choice if you are trying to control your blood sugar level.
    Lean beef
    Including appropriate amount of lean beef in your diet is beneficial in enhancing your memory because of its iron content.While most men get enough iron in their diet,those who are on a strict diet and are sticking mostly to chicken,egg whites and fish as sources of protein may be running a bit low.
    Iron deficiency can have a significant effect on brain function and impair learning abilities, eventually putting you at an increased risk for developing Alzheimer's disease.So,be sure you aren't cutting out good sources of iron from your diet一even if you,re striving for maximum fat loss.

    Supplementing with DHA in sunflower seeds is good for the development and maintenance of memory performance.
    A:Right
    B:Wrong
    C:Not mentioned

    答案：B
    解析：
    本题给出的信息是正确的。依据是文章第一段第二句：" People care their diets in terms of whether it helps them build muscle or lose fat,but they neglect to think of how food can improve memory.”许多人注意他们的饮食，主要是关注它是否会帮助他们锻炼肌肉或减肥，但他们疏于考虑食物是如何能改善记忆的。所以选A。
    本题给出的信息是错误的。依据是文章第四段最后一句："Studies have suggested that supplementing with DHA,which is found in fish oil,is beneficial for the development and maintenance of memory performance.”研究表明，对在鱼油中发现的DHA的补充，有利于发展和维持记忆功能。所以选B。
    本题给出的信息是正确的。本题考查考生的概括能力。依据是文章在第五段第三句："Vitamin E is one of the primary antioxidants that helps decrease the decline of memory as you get old…”维生素E是一种主要的杭氧化剂，可以帮助减少你在变老时记忆的衰退……这与本题所描述的：当你老的时候，维生素E有助于减少记忆力下降的现象。这恰是对原文句子的复现。所以选A。
    本题给出的信息是正确的。依据是文章第八段："Besides, blueberriesrank low on the glycemic（血糖）index scale,making them a good fruit choice if you are trying to control your blood sugar level.”此外，在血糖生成指数表中蓝毒排名靠后，这使之成为控制血糖水平的一个良好的水果选择。这与本题所描述的“蓝毒是人们控制血糖水平的较好的水果的选择”相一致。所以选A。
    本题给出的信息是错误的。依据是第九段第二句："While most men get enough iron in their diet,those who are on a strict diet and are sticking mostly to chicken,egg whites and fish as sources of protein may be running a bit low.”虽然大多数人在饮食中已获得足够的铁质，但那些严格节食的人和坚持吃鸡肉、蛋白和鱼类作为蛋白质主要来源的人铁质获取量有点儿低。"while”一词表明对比，说明到本题所说的“大部分人都在严格节食”是错误的，所以选B。
    本题没有给出这样的信息。
    本题给出的信息是错误的。依据是文章最后一段："Iron deficiency can have a significant effect on brain function and impair learning abilities,eventually putting you at an increased risk for developing Alzheimer's disease.So,be sure you aren't cutting out good sources of iron from your diet一even if you're striving for maximum fat loss.”缺铁可以产生重大影响，损害大脑功能和学习能力，最终增加发展成老年痴呆的风险。所以，要确保你没有把含铁较高的食物从你的食谱中撤掉―即使你一直在致力于最大限度地减轻体重。这与题目所描述的“如果你想尽量多地减肥，把含铁较高的食物从你的食谱中撤掉”相悖，所以选B。

  • 第16题：

    单选题
    Advertisement: The most flavorful olives in the world are kalamata olives. The more kalamata olives used to make a bottle of olive oil, the more flavorful the oil, and no company buys more kalamata olives than Zorba’s Olive Oil. Therefore, when you buy Zorba’s Olive Oil, you’re buying the most flavorful olive oil available today.　 The reasoning presented in the advertisement is flawed because it overlooks the possibility that:
    A

    Not all of Zorba’s competitors use kalamata olives in their oil.

    B

    Zorba’s sells more olive oil than any other company.

    C

    The most flavorful olive oil is not necessarily the best olive oil.

    D

    Because of bulk discounts, Zorba’s pays less per kilogram of kalamata olives than does its competitors.

    E

    The number of kalamata olives harvested every year is far less than the number of Spanish olives harvested every year.


    正确答案： B
    解析：
