专题练(十三)　说明文阅读(3)　(分值：50分) (2024·浙江1月) In the past few years，online learning has become a significant part of the university and college experience. 36 But are all online courses created equal? How can you be sure that digital learning is right for you？ 37 We interviewed students and professors to get their advice about online courses.The most obvious advantage of online learning is that you can study anywhere and anytime. 38 “I think a point that many people ①lose sight of is how easy it can be to fall behind schedule，” says graduate student Amanda Bindman.Before choosing to study online，consider whether you’re a ②self-motivated learner and if the material seems interesting enough to keep you going. The tip that comes up most often is simple: build online courses into your weekly schedule，just like what you would do with in person courses. 39 He noted that his online students usually end up with lower grades.It is so easy to let an online course slide，but your grades will suffer as a result.Be sure to schedule ③set times to watch your lectures，read materials and contribute to online discussion boards. 40 A social connection is often a big part of learning.There are things you can do to ④ease this problem.Jessica Pink，an undergraduate student，suggests taking online courses with a friend，so you can motivate each other to stay on track.You can also find students on the class discussion board to organize a study group，or schedule ⑤in-person meetings with your professor to discuss course concepts. A．But that doesn’t mean there aren’t deadlines. B．Your motivation should be your main concern. C．Do you know that online courses are also part of your education? D．Professor Alex Davidson teaches the same course in person and online. E．The chief complaint about online courses is that they lack human interaction. F．If you take an online course，what can you do to ensure the best possible grade? G．A survey found that 29 percent of college students registered for online courses. 36．答案　G 解析　由空前一句可知，在线学习是大学生活中很重要的一部分，本空要说跟这种现象的具体表现有关的话题，故G选项(一项调查发现，29%的大学生注册了在线课程)能承接上文，符合题意。故选G。 37．答案　F 解析　上文对在线课程提出疑问，本空可以继续提出疑问，故F选项(如果你参加了在线课程，你能做些什么来确保尽可能好的成绩？)能承接上文，符合题意。故选F。 38．答案　A 解析　由空前一句可知，在线学习具备的优势是可以让你随时随地学习，本空要说跟“学习时间”有关的话题，故A选项(但这并不意味着没有最后期限)与上文构成转折关系，that指代上一句，符合题意。故选A。 39．答案　D 解析　由空后一句可知，本空要说跟“在线课程的老师”有关的话题，故D选项(Alex Davidson教授亲自教授和在线教授同样的课程)能引起下文，符合题意。下文中的He指代D项中的“Professor Alex Davidson”。故选D。 40．答案　E 解析　由最后一段内容可知，本空要说跟“人们之间的互动”有关的话题，故E选项(对在线课程的主要抱怨是它们缺乏人与人之间的互动)能引起下文，符合题意。E选项中的human interaction与空后的social connection呼应。故选E。 语境猜词 ①lose sight of sth 忽略某事 ②self-motivated＝(合)self＋motivated自我激励的；主动的 ③set(熟义：v.设置，放)　生义(文义)：adj.固定的 ④ease(转) n．→v.缓解 ⑤in-person＝(合)in＋person亲自的 以上文章中第38、39题考查了“代词指代”，解题技法如下： A (2024·广东惠州一模) Shopping in the sales feels like a subtle way to spend.Lower prices naturally equal money saved. 1 Sometimes you think you’re getting a bargain，but actually you’re paying more than you need to.So，follow the tips below and you’ll hopefully be ①on the right track. Only buy essentials.You might have been tempted to buy a much higher item than you actually need，simply because we’re dazzled by the size of the discount.So despite the savings made on the full-price item，it’s actually a huge waste of cash. 2 You can even have a “need” note which you add to regularly，allowing you to focus your shopping during the sales. 3 Just because there’s a sale running with a lower price doesn’t mean you can scramble for the goods immediately.If you can wait，some price history websites are a great way to get a sense of any regularly occurring price variations.Certain items will have a life cycle too.Christmas cards and decorations are bargains in January while TVs tend to be at their lowest prices in the early summer when the newer models are released. 4 So this is only a strategy for ②non-essentials. Check for alternatives.Finally，even if you think you’ve got the best price out there—or at least one you’re happy to pay—it’s worth checking you’re not ③overpaying still when compared to similar products. 5 That could mean staying away from ④high-end brands，looking for secondhand items or trying a different but similar style. A．Time when you buy. B．Compare prices now. C．Sadly，there are tricks played by retailers. D．It’s easy to get caught up in sales and spend when you don’t need to. E．The best way to avoid this is to create a must-have list before shopping. F．There may well be cheaper substitutes that do the same job but cost less. G．But you might have fewer options to choose from，or will even miss out. 1．答案　C 解析　根据上文“Shopping in the sales feels like a subtle way to spend.Lower prices naturally equal money saved.”以及下文“Sometimes you think you’re getting a bargain，but actually you’re paying more than you need to.”可知，低价促销并不意味着省钱，C选项(遗憾的是，零售商经常运用一些伎俩)承上启下。故选C。 2．答案　E 解析　根据上文“You might have been tempted to buy a much higher item than you actually need”以及下文“You can even have a ‘need’ note which you add to regularly，allowing you to focus your shopping during the sales.”可知，空处应为避免被诱导的办法。E选项(避免这种情况的最好方法是在购物前创建一个必备清单)符合语境，其中的this指代上文的been tempted to buy a much higher item than you actually need，且a must-have list与下文的a “need” note对应。故选E。 3．答案　A 解析　该空为主旨句。根据下文“Just because there’s a sale running with a lower price doesn’t mean you can scramble for the goods immediately.”以及“Certain items will have a life cycle too.”可知，本段建议读者合理安排购物的时间，以便获得更低的价格。A项“安排你的购物时间”可以作为小标题，总领全段。故选A。 4．答案　G 解析　根据下文“So this is only a strategy for non-essentials.”可知，这只适用于非必需品，由此推知空处应涉及弊端，G选项(但你的选择会更少，甚至会错过)符合语境，与下文构成因果关系，且与上文“圣诞卡和装饰品在一月份是便宜货，而电视往往在初夏新款发布时价格最低”承接自然。故选G。 5．答案　F 解析　上文“it’s worth checking you’re not overpaying still when compared to similar products”提到比较类似的产品的价格，结合空后的“That could mean...”可知，空处应为That指代的具体内容。F项(很可能有更便宜的替代品可以做同样的工作，但花费更少)符合语境，其中的cheaper substitutes为本段主旨句中alternatives的复现，下文也举出例子secondhand items和a different but similar style。故选F。 语境猜词 ①on the right track做得正确 ②non-essential＝(派)non＋essential非必需品 ③overpay＝(合)over＋pay多付 ④high-end＝(合)high＋end高端的；高档的 B (2024·浙江嘉兴一模) Ensuring that your home is as ①energy-efficient as it can possibly be is essential.Take the steps listed below，and you will be living in an energy-efficient home in no time. 6 To stop it in its tracks，you must invest in having your house insulated(隔热的)．Taking such action may demand some cost in advance，but it will be sure to save you over ￡100 a year when it comes to your energy bills. The old boilers(锅炉) are not as energy-efficient as the very latest models in this field. 7 By investing in a ②top-of-the-line boiler，you’ll no doubt tap into a number of savings.What’s more，making this kind of investment will also be sure to lower your home’s carbon emissions. Only when you know how much energy you use can you take action to be less wasteful and more ③resourceful in this instance. 8 To assist you in taking on this extremely important challenge，you might want to consider fitting an energy ④monitor in your home. 9 But if you’re lucky，your electricity provider will give you one for free.This monitor will provide you and your family with constant updates on the amount of energy you are using on a day-to-day basis. With just twelve years (now seven years) to go until climate change alters earth forever，now is the time for you to play your part in protecting the planet that you live in. 10 A．The investment demanded in this instance is significant. B．Taking such action will help you adapt to climate change. C．Generally，this type of device will cost between ￡25 and ￡40. D．It means you should try to keep track of energy consumption. E．By putting the above advice into practice，you’ll be ⑤green soon. F．Most of your home’s wasted energy will escape through your roof. G．It might be high time to update yours if you haven’t done so for years. 6．答案　F 解析　由下文“To stop it in its tracks，you must invest in having your house insulated(隔热的)．”可知，这里指需要阻止房内能源外流。F项(你家里浪费的大部分能源都会从屋顶逃逸出去)符合语境，下文it指代选项中的wasted energy。故选F。 7．答案　G 解析　由上文“The old boilers(锅炉) are not as energy-efficient as the very latest models in this field.”可知，旧锅炉比最新款锅炉更耗能，G项(如果你已经多年没有更新自己的锅炉，现在可能是时候更新了)承接上文，符合语境，其中for years与上文old对应，update与latest对应。故选G。 8．答案　D 解析　由上文“Only when you know how much energy you use can you take action to be less wasteful and more resourceful in this instance.”可知，要了解自己用了多少能源，D项(这意味着你应该努力跟踪能源消耗情况)符合语境，有承上作用。选项中It指代上文内容。故选D。 9．答案　C 解析　上文提到安装能源监控器，由下文“But if you’re lucky，your electricity provider will give you one for free.This monitor will...”推知，空处会涉及能源监控器的价格，C项(一般来说，这种设备的价格在25到40英镑之间)承上启下，符合语境，选项中this type of device指代上文的energy monitor，￡25 and ￡40与下文for free对应。故选C。 10．答案　E 解析　由上文“With just twelve years (now seven years) to go until climate change alters earth forever，now is the time for you to play your part in protecting the planet that you live in.”可知，作者号召读者保护地球，E项(把以上建议付诸实践，你很快就会变得更环保)符合语境，其中 the above advice指上文提到的建议，对上文有总结作用。故选E。 语境猜词 ①energy-efficient＝(合)energy＋efficient节能的 ②top-of-the-line＝(合)top＋of＋the＋line顶级的；最高档的 ③resourceful＝(派)resource＋ful足智多谋的；机智的 ④monitor(熟义：n.班长)　生义(文义)：n.监视器 ⑤green(熟义：adj.绿色的)　生义(文义)：adj.环境保护的 C (2024·广东江门一模) It’s no surprise that there’s a link between exercise and mental health.But scientists have now made it official：research has found a direct connection between movement and mood.Why does exercise hold so many benefits for our mental health? 11 When our muscles tighten，chains of amino acids(氨基酸) called myokines(肌细胞因子) are released into the ①bloodstream. 12 This communication increases adaptation to stress，reduces symptoms of anxiety and has a direct effect on depression. A recent study published in the British Journal of Sports Medicine showed that treatment for depression can be much more effective when physical activity is added to the usual care. 13 “While exercise is not a substitute for professional mental health treatment，physical activity can complement and enhance the effects of the treatment，” says lead researcher Ben Singh，a research fellow at the University of South Australia.He says regular exercise in a group setting can boost ②self-esteem and decrease feelings of isolation and ③loneliness. Exercise helps build key connections between the networks within the brain，too. 14 Studies have shown that physical activity stimulates creativity，sharpens judgement skills and improves mental energy.It can also help to slow ④age-related cognitive decline，possibly even slowing the pace of developing Alzheimer’s disease. 15 In this way you’ll keep going back to them.Experts suggest that you aim for a minimum of 10 to 30 minutes，three to five days each week.Getting sweaty is good for your body and mind. A．It can improve overall cognitive performance. B．They help your muscles and organs communicate. C．The answer，studies say，lies in our brain chemistry. D．Here are the suggestions that you are supposed to pay attention to. E．It is amazing to consider how moving our bodies can affect our minds. F．To get the biggest health boost，the key is to be engaged in sports you enjoy. G．Participants found benefits after 12 weeks of exercising for 30 to 60 minutes a day. 11．答案　C 解析　根据上文“Why does exercise hold so many benefits for our mental health？”可知，本句主要回答上文的问题，下文“When our muscles tighten，chains of amino acids(氨基酸) called myokines(肌细胞因子) are released into the bloodstream.”提到肌细胞因子被释放，正是C选项中chemistry的体现。故C选项“研究表明，答案在于我们大脑中的化学物质”符合语境，故选C。 12．答案　B 解析　上文提到肌细胞因子被释放到血液中，结合下文“This communication increases adaptation to stress，reduces symptoms of anxiety and has a direct effect on depression.”可知，本句承接上文，说明肌细胞因子的具体作用，B选项中They指代空格前myokines，空格后This communication指代选项中your muscles and organs communicate。故B选项“它们帮助你的肌肉和器官交流”符合语境，故选B。 13．答案　G 解析　根据上文“A recent study...showed that treatment for depression can be much more effective when physical activity is added to the usual care.”以及下文研究人员说的话可知，本句应与此项研究有关，故G选项“参与者在12周后发现每天锻炼30到60分钟是有益的”符合语境，故选G。 14．答案　A 解析　根据上文“Exercise helps build key connections between the networks within the brain，too.”以及下文“Studies have shown that physical activity stimulates creativity...to slow age-related cognitive decline...”可知，本段主要是在说明运动对人的大脑功能的具体好处，故A选项“它可以提高整体认知能力”符合语境，选项中It指代上文的Exercise，故选A。 15．答案　F 解析　根据下文“In this way you’ll keep going back to them.”可知，该空应提到一种让你容易坚持运动的方法，且提到them的指代对象，故F选项“为了最大程度地促进健康，关键是要参加你喜欢的运动”符合语境，空格后面In this way对应F选项中to be engaged in sports you enjoy，them指代sports you enjoy。故选F。 语境猜词 ①bloodstream＝(合)blood＋stream血流 ②self-esteem＝(合)self＋esteem自尊(心) ③loneliness＝(派)lonel(y)＋i＋ness孤独(感) ④age-related＝(合)age＋related 与年龄相关的 学科网（北京）股份有限公司 $$ 专题二　七选五阅读 专题练(十三) 说明文阅读(3) 内容索引 做真题　悟技法 练模拟　提能力 (2024·浙江1月) In the past few years，online learning has become a significant part of the university and college experience. 做真题 悟技法 语篇解读　这是一篇说明文。文章主要说明了在线学习的注意事项。 36 But are all online courses created equal?
