2.解题思路
做七选五时，一定要胸怀大局，整体把握。首先，要明确文章的主旨中心，理清文章层次结构。然后把握空格前后句所提供的语境，体会整体表达的语义倾向。同时要关注备选项所具有的结构特征和语义的暗示。整体来说，2018年全国II卷七选五是一篇说明文，层次分明，结构紧凑。本文围绕话题健康生活，论述了锻炼与健康的相互关系。全文采用总分总结构。文章一开始，引出话题：晨练与身体健康 。然后围绕晨练对于身体健康之外的四点好处。总共六段。首段和末端分别属于总起和总结。中间四个段落，采用类小标题的方式，即首句就是其段落的主旨句。试题难度与往年持平，难度不大，但做还需要认真仔细。
36.空格位于首段段中，作为文章的起始段，做题时要体会首段的作用和前后句的逻辑关系。从文章的行文思路来说，此处是过渡句，要承接段首句“ifyouarealreadymakingthetimetoexercise...”分析与G选项“ifyouareplanning todo exercise regularly”是相同句型，并且话题一致，属于平行结构；又要开启下文，由G选项句末的“ If you are planning to do exerciseregularly, or you're doing it now, then listen up！”引起首段末句。同时，空格前后句，仅紧紧围绕“ work out”，这恰好对应G选项中的“do”。
37.空格位于第二段段末，由于空格句属于类小标题统领下，所以抓住首句“Your productivity is improved（提高你的效率）”空格前前句中的“make you more awake”与E项中的“keep your head clear”话题一致，都是对主题句的阐释。做题要注意前后文逻辑关系和把握话题的一致性。
38.空位于段中，做题时，抓住本段的主旨句和前后句的逻辑关系。 "Your metabolism(新陈代谢) gets a head start"为本段的主旨句，空后句的“getting the calories burning”均与“F. After you exercise, you continue toburn calories throughout the day.运动后，你一整天都在燃烧卡路里”相关。
39题和40题位于段首首句。而此首句具有类小标题的作用，都在考查段落主旨，做题时根据后文中的关键词或者后面语境所表达的含义来作分析和判断。
39.空格后表达的语意是：研究表明，早起锻炼的人比晚上锻炼的人睡得更好。运动使你精力充沛，很兴奋，很难放松，也很难睡得很好。显然，话题围绕“睡眠”。所以抓住核心话题“sleep”，自然定位到B项，只需要核查一下。
40.空格后表达的语意是
：如果你早上锻炼得很好，那么你更有可能坚持一天中的健康饮食选择。谁会因为吃垃圾食品而破坏他们的良好锻炼呢？你会想要 继续关注积极的选择。抓住核心话题“选择”和“food”，B项和C项备选，C选项干扰较强，但太具体，同时也未能体现本段最核心的信息“more likely to stick to healthy food choices健康饮食选择”，故选A.
