【46题详解】
考查对上下文的理解及推理判断能力。根据上一句“Activities that have the highest value for brain health are novel and complex to each particular person” 对大脑健康价值最高的活动对每个人来说都是新奇而复杂的。分析选项可知，C项（The things that challenge you the most have the most value for your brain最能挑战你的东西对你的大脑最有价值）。C项中的（the highest value for brain health）“对大脑最有价值”与空前的“the highest value for brain health”是同义词转换。C项中的“challenge you the most（最挑战你的）”与文章中的“novel and complex to each particular person（新奇而复杂的）”也是同义转换。而且在意义C项是与本段的意义一致。故选C。

考查对上下文的理解及推理判断能力。本段的中心句“Exercise regularly（经常锻炼）”。分析选项可知A项（Engaging in it regularly also reduces the risk of depression and anxiety.）中的词Engaging in it regularly与Exercise regularly是一致的。再根据空前的“Exercise can improve our energy levels, sense of well-being, sleep, and brain health.” 运动可以提高我们的精力、幸福感、睡眠和大脑健康。可知A项（Engaging in it regularly also reduces the risk of depression and anxiety经常运动也会降低抑郁和焦虑的风险）中的“aslo”是递进关系，说明A项进一步说明经常锻炼的好处。由此可推断出A项符合题意，故选A。

【49题详解】
考查对上下文的理解及推理判断能力。本段的中心句为“Be health conscious（注重健康）”。本段叙述对我们来说健康很重要。我们要对自己的健康负责。分析选项可知D项（Physicians work for us, and when it comes to our bodies, we are the boss医生为我们工作，说到我们的身体，我们要做我们身体的主人）中的when it comes to our bodies, we are the boss 即是说我们要做我们身体的主人（we are the boss），即对应文中的“我们要对自己的健康负责（we are in charge of managing of our bodies）”。本段中的“physician”也在D项中复现。综合分析可知D项与本段意义一致，且有词的复现，D项符合题意，故选D。
【50题详解】
考查对上下文的理解及推理判断能力。本段的中心句“Slow down and appreciate the silence（放慢脚步，欣赏寂静）” 本段说我们的快节奏的生活方式（A fast-paced lifestyle）让我们没有时间来放松，导致我们有压力，对我们的健康和幸福有影响。分析选项可知G项（Our society is developing quickly, leaving us with little time to relax and process our environment.）“我们的社会发展很快，我们几乎没有时间来放松和处理我们周围的环境。”与本段“快节奏的生活让我们无法放松意义”一致。且G项中的A fast-paced lifestyle即是说明我们有“快节奏的生活a fast-paced lifestyle”。G项符合题意，故选G。
【点睛】七选五题型考察学生把握整篇文章的布局和逻辑层次关系和把握微观信息间关联性这种题一般可从以下方面来做：
 （1）看首段，跳过空格快速通读全篇，确定文章体裁，抓住文章结构，分析篇章结构，了解文章大意。首段的末句一般是全文的主题所在，首段的末句对于快速掌握文章的主题具有重要意义。
（2）精读空格前后两句，利用各种衔接手段选择正确的选项填入空格。七选五空出的是整个句子，可以通过选项中某个名词或动词跟空前或空后的一致性或者相关性来确定这两个句子之间有一种关联性，从而选择正确的答案。
（3）看选项，找出与空前空后句中心词同义，近义或相关性的词语，实现关键词的对接，尤其是词（或短语）的复现。先易后难，各个突破。通过阅读选项，有可能根据选项中的关键词找出正确选项。如第4小题，本段的中心句为“Be health conscious（注重健康）”。本段叙述对我们来说健康很重要。我们要对自己的健康负责。分析选项可知D项（Physicians work for us, and when it comes to our bodies, we are the boss）中的when it comes to our bodies, we are the boss 即是说我们要做我们身体的主人（we are the boss），即对应文中的“我们要对自己的健康负责（we are in charge of managing of our bodies）”。本段中的“physician”也在D项中复现。综合分析可知D项与本段意义一致，且有词的复现，D项符合题意，故选D。
（4） 解题的关键是能娴熟地利用各种衔接手段。尤其要注意代词，连词等。如表示转折关系的but，though, however ，以及递进并列词also等。如第2小题，本段的中心句“Exercise regularly（经常锻炼）”。分析选项可知A项（Engaging in it regularly also reduces the risk of depression and anxiety.）中有词Engaging in it regularly与Exercise regularly是一致的。再根据空前的“Exercise can improve our energy levels, sense of well-being, sleep, and brain health.” 运动可以提高我们的精神、幸福感、睡眠和大脑健康。可知A项（Engaging in it regularly also reduces the risk of depression and anxiety.经常运动也会降低抑郁和焦虑的风险）中的“aslo”是递进关系，说明A项进一步说明经常锻炼的好处。由此可推断出A项符合题意，故选A。
最后，用代入法，检查答案是否合理，将所有选择答案放回空白处，通读全文，检查文章内容是否语义连贯合理、紧扣主题，语篇结构是否通顺连贯、具有一致性、合乎逻辑，写作思路是否清晰明了，格式以及用语是否恰当贴切，从而判断选择的答案是否正确。
