2026年同步练习册智慧作业八年级英语下册人教版第4页答案
C
When people talk about "time to relax", their ideas of free-time activities vary—but most agree these activities matter a lot.
Some people, like 16-year-old student Mia, think hobbies like drawing or flying kites are "brain breaks". "After 5 hours of classes," she says,"spending 20 minutes drawing helps me focus better on homework later." A teacher, Mr Lee, adds that outdoor activities (like cycling with friends) don't just relax bodies—they build social skills too.
But not everyone saw it this way before. Last year, 14-year-old Tom thought free time was "wasted time" and used it to do maths exercises. However, he felt more tired and did worse on tests. Now, he plays basketball for 30 minutes daily. "I feel calmer, and my grades have gone up!"
Doctors say these changes make sense. Free-time activities lower stress hormones(荷尔蒙), which lets both our brains and bodies work better. No matter what the activity is, taking time to relax isn't lazy—it's necessary.

解析

【分析】
本题为英语阅读理解题,需先通读全文把握主旨,再针对各小题的题型(主旨大意题、细节理解题、推理判断题)定位原文信息解题:23题需归纳全文核心观点;24题定位Mia关于画画好处的表述;25题结合Tom的前后变化推断结论;26题定位医生对休闲活动的观点。
【解析】
23题:全文围绕“休闲活动对人的重要性”展开,通过Mia的例子说明休闲活动能提升学习专注度,Lee老师指出户外活动可培养社交技能,Tom的经历证明休闲活动改善学习状态,最后医生强调休闲活动的必要性,故主旨为休闲活动的重要性,选B。
24题:定位原文Mia的话“spending 20 minutes drawing helps me focus better on homework later”,对应选项A(帮助做作业更仔细);B是Lee老师提到的社交技能,C是Tom的情况,D无依据,故选A。
25题:Tom之前用空闲时间做数学导致更累、成绩差,现在每天打篮球后“feel calmer, and my grades have gone up”,可推断休闲活动帮助他的学习,选C;A与原文矛盾,B与原文相反,D表述绝对,故选C。
26题:定位医生的表述“Free-time activities lower stress hormones”,对应选项B;A与原文“isn't lazy”矛盾,C“only good for students”无依据,D与原文“necessary”矛盾,故选B。
