Care how you feel. __2__ You can feel them throughout your body.When someone approaches you with a request，pay attention to your body's response.It tells you how to respond before you even say a word.For example，as they speak，you might feel muscle tension.This is a signal from your body to say no. Don't delay giving your response. When someone approaches you with a request，a common strategy is to buy time.By doing this，you secretly hope that they will miraculously forget the request，and that you will be off the hook.However，this strategy does not work.Not resolving the matter in real time allows emotional forces such as guilt to influence you.__3__ Don't overexplain yourself. In an effort to cope with difficult emotions such as guilt，you tend to overshare the reasons for saying no.However，the more information you share，the more likely you are to be persuaded into saying yes.By sharing information，you are only providing someone with the opportunity to build a case for overriding your boundaries.__4__ You can be kind and direct when setting boundaries. __5__ It can take time to become expert in any skill.The same holds true with setting boundaries.At first，setting boundaries can feel uncomfortable.You may struggle for words or not sound convincing，but over time，it gets easier.Remember that not setting boundaries is also hard.Constantly walking on eggshells for fear of upsetting people is an exhausting way to live. A．Set boundaries often. B．Don't be afraid of explaining. C．Emotions are not just in your head. D．The reason is that you lack firm boundaries. E．When saying no，you should keep it short and sweet. F．As a result，a delayed no may turn into a reluctant yes. G．Setting the mental boundary lets you play multiple roles at home. 【语篇解读】　这是一篇说明文。文章介绍了如何设定界限的几个方法。 1．D　由上文“We've all been there：Sometimes you know that you need to decline someone's request，but somehow，in the end，you reluctantly agree to take on an additional responsibility.(我们都经历过：有时你知道你需要拒绝别人的请求，但不知何故，最终你不情愿地同意承担额外的责任)”，再结合下文“Here are ways to sharpen this tool.(这里有一些方法可以磨砺这个工具。)”和小标题“Care how you feel.(关心你的感受)”，“Don't delay giving your response.(不要拖延回应)”，“Don't overexplain yourself.(不要过度解释自己)”介绍设定界限的方法，可知该空内容与你为什么没办法拒绝别人的请求相关，且原因与设定界限有关，D选项“原因是你缺乏明确的界限。”切合语境。故选D项。 2．C　由小标题“Care how you feel.(关心你的感受)”和下文“You can feel them throughout your body.When someone approaches you with a request，pay attention to your body's response.(你可以感觉到它们遍布全身。当有人向你提出请求时，注意你身体的反应)”可知，“them”指代某些情绪情感，C选项“情绪不仅存在于你的脑海中。”引出下文关于身体感知情绪的内容，表明情绪不仅是心理上的，身体也会有相应的反应，切合语境。故选C项。 3．F　由小标题“Don't delay giving your response.(不要拖延回应)”和上文“When someone approaches you with a request，a common strategy is to buy time.By doing this，you secretly hope that they will miraculously forget the request，and that you will be off the hook.However，this strategy does not work.Not resolving the matter in real time allows emotional forces such as guilt to influence you.(当有人向你提出请求时，一个常见的策略是争取时间。通过这样做，你暗自希望他们会奇迹般地忘记这个请求，而你会摆脱困境。然而，这种策略并不奏效。不实时解决问题会让内疚等情绪力量影响你)”可知，作者建议不要拖延回应，要实时解决问题，然而人们总是拖延回应以至于会让内疚等情绪力量影响自己，该空应承接上文继续讲拖延回应会带来的不良后果，F选项“因此，拖延的‘不’可能会变成不情愿的‘是’。”切合语境。故选F项。 4．E　由小标题“Don't overexplain yourself.(不要过度解释自己)”，上文“In an effort to cope with difficult emotions such as guilt，you tend to overshare the reasons for saying no.However，the more information you share，the more likely you are to be persuaded into saying yes.(为了应对内疚等困难情绪，你往往会掩盖拒绝的原因。然而，你分享的信息越多，就越有可能被说服说“是”)”和下文“You can be kind and direct when setting boundaries.(在设定界限时，你可以善良而直接)”可知，作者建议拒绝不要过多解释，解释越多，别人越不能接受你拒绝的原因，且拒绝时可以善良而直接，E选项“说‘不’时，你应该简短而甜蜜。”切合语境。故选E项。 5．A　该空选取小标题，需总结下文。由下文“It can take time to become expert in any skill.The same holds true with setting boundaries.At first，setting boundaries can feel uncomfortable.You may struggle for words or not sound convincing，but over time，it gets easier.(成为任何技能的专家都需要时间。设定界限也是如此。起初，设定界限可能会让人感到不舒服。你可能很难用词，或者听起来不太有说服力，但随着时间的推移，这会变得更容易)”可知，下文提到设置界限需要时间和练习，A选项“经常设定界限。”切合语境。故选A项。 七选五B2 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 (23－24·高一下江苏无锡一模)Whether you're looking to lose a few pounds，spend more time at the gym or learn a language，turning bad habits into good ones is all about self-control.Some of us have more than others.And research shows that those with more self-control tend to be happier.But the problem is that we usually only get rewarded in the future.__1__ Michael Inzlicht is a professor of psychology at the University of Toronto and a self-control researcher.He says that the ironic thing about self-control is that those who are really good at it don't have to practice it.__2__ When you love and desire something that tends to be better for you，like studying，working hard or exercising，for example，you don't have to think about doing it.Inzlicht says that these types of individuals generally have what's called “trait self-control” meaning it's an aspect of their personality. When it comes to improving self-control，Inzlicht says it's difficult to change the personality that you're born with.__3__ A wide body of research shows that you can improve self-control for a particular behavior you want to change or a habit you'd like to develop.For example，Inzlicht says that when we get paid to make life changes，we're more likely to make them.Some gyms will charge you a certain amount of money for a year-long membership and then give you a few cents back every time you come.__4__ __5__ Part of failing at developing self-control is in getting frustrated at yourself for not changing overnight.If you're building self-control in losing weight，for instance，don't try switching to nothing but fruits and vegetables all at once because it's too dramatic a change—not to mention unsustainable. A．However，this doesn't mean you can do nothing about it. B．Another tip for success，says Inzlicht，is making gradual steps. C．Even a small amount of money can encourage people to work out. D．They can maintain the good habits all the time without much effort. E．Thus，we are constantly weighing whether to wait or to have it right now. F.Don't be afraid of frustration，since it is necessary for your improvement. G．Actually，self-control improvement can bring about benefits to all individuals. 【语篇解读】　本文是一篇说明文。文章介绍了自控力强的人往往更快乐，虽然真正擅长自控的人无需刻意练习，而且人们难以改变天生性格，但依然有一些方法可以提升自控力，例如针对特定行为或习惯，用报酬加以激励，以及循序渐进。 1．E　前文“And research shows that those with more self-control tend to be happier.But the problem is that we usually only get rewarded in the future.(研究表明，自控能力强的人往往更快乐。但问题是，我们通常只在未来得到奖励)”指出自控能力强可以带来快乐，但这种快乐在未来才能得到，因此E项“Thus，we are constantly weighing whether to wait or to have it right now.(因此，我们不断地权衡是等待还是现在就拥有它)”符合语境，表明我们会纠结于是自控以得到未来的快乐，还是不自控现在就获得快乐，是前文矛盾的结果，承接前文。故选E。 2．D　前文“He says that the ironic thing about self-control is that those who are really good at it don't have to practice it.(他说，具有讽刺意味的是，那些真正擅长自我控制的人并不需要练习自我控制)”指出擅长自控的人不需要练习自控，后文“When you love and desire something that tends to be better for you，like studying，working hard or exercising，for example，you don't have to think about doing it.(当你喜欢并渴望一些对你更好的事情时，比如学习、努力工作或锻炼，你不必考虑去做)”用具体的例子说明这种自控可以自然发生，因此D项“They can maintain the good habits all the time without much effort.(他们可以毫不费力地一直保持好习惯)”符合语境，说明这样的人可以轻松保持好习惯，是对前文的解释，后文是对其例证，选项中的They指代前文的those who are really good at it.故选D。 3．A　前文“When it comes to improving self-control，Inzlicht says it's difficult to change the personality that you're born with.(说到提高自我控制能力，Inzlicht说，很难改变你与生俱来的性格)”指出提高自控力很困难，后文“A wide body of research shows that you can improve self-control for a particular behavior you want to change or a habit you'd like to develop.(大量的研究表明，你可以提高你想要改变的特定行为或你想要养成的习惯的自制力)”说明特定行为或习惯的自控力是可以提升的，因此A项“However，this doesn't mean you can do nothing about it.(然而，这并不意味着你对此无能为力)”符合语境，指出提高自控力也是有办法的，和前文构成转折，引出后文，其中的this指代前一句话。故选A。 4．C　前文“For example，Inzlicht says that when we get paid to make life changes，we're more likely to make them.Some gyms will charge you a certain amount of money for a year-long membership and then give you a few cents back every time you come.(例如，Inzlicht说，当我们因为改变生活而得到报酬时，我们更有可能做出改变。有些健身房会向你收取一定数额的一年会员费，然后每次你来的时候都会返还你几美分)”指出报酬可以推动人做出改变，并举出健身房返还一小部分费用的例子，因此C项“Even a small amount of money can encourage people to work out.(即使是少量的钱也能鼓励人们去锻炼)”符合语境，说明被返还的费用可以让人坚持锻炼，承接前文。故选C。 5．B　后文“Part of failing at developing self-control is in getting frustrated at yourself for not changing overnight.If you're building self-control in losing weight，for instance，don't try switching to nothing but fruits and vegetables all at once because it's too dramatic a change—not to mention unsustainable.(发展自我控制失败的部分原因是对自己没有在一夜之间改变而感到沮丧。例如，如果你在减肥过程中建立自我控制，不要试图一下子只吃水果和蔬菜，因为这是一个太大的变化——更不用说不可持续了)”指出培养自控不是一蹴而就的事情，并以减肥中饮食的改变为例加以说明，因此B项“Another tip for success，says Inzlicht，is making gradual steps.(Inzlicht说，成功的另一个秘诀是循序渐进)”符合语境，点明培养自控需要循序渐进，契合后文内容，适合作为段落主旨句。故选B。 七选五B3 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 (2025·云南大理二模)The comparison thief loves to sneak into our minds without warning and steal our joy or peace.And with social media flooding our lives，it's easier than ever to find someone “better” to compare ourselves to.Constantly measuring ourselves against others can be an exhausting mind game.__1__．We either walk away feeling inadequate (不足的) or get a false sense of fulfillment，believing we are better than others.I constantly struggled with this battle.So，what did I do? __2__．I learned the art of seeking inward.At the start of each day，I told myself to love and appreciate myself and give myself confidence instead of looking to others to do that.Getting your mindset right at the beginning of the day sets you up for a successful day of less comparison. Accept the real self.One of the biggest things that helped me stop comparing myself was finding out who I was and accepting her.When witnessing my friend's gorgeous and well-organized house，I naturally tended to compare mine with hers.__3__，but I've accepted my humanity.We are all imperfect beings deserving of love，respect，and appreciation.Celebrating the other person and accepting myself was the opportunity to start again with the truth. Restrict social media time.I stopped following social media accounts that made me feel inadequate or insecure and set a boundary about my time on those apps.They can become a wormhole and suck up the precious time we have.__4__．Better yet，put your phone down and engage with the people whose opinion truly matters. Be present.I began to train my mind to trust that I did not need to plan，control，and schedule everything.__5__．I wouldn't worry about recording a moment for others to see.Instead，I would choose to focus on seeing and appreciating it for myself. A．Reset my mind B．Seek for confidence C．In it，we always lose D．Set a timer if you must E．Feelings of failure instantly arose F．What I needed to prepare was a gift for her G．All I needed to do was living in the moment 【语篇解读】　本文是一篇说明文。本文主要讲述了如何克服总爱与他人比较的心理，包括学会欣赏自己、接受真实的自我、限制社交媒体使用时间以及专注于当下等建议。 1．C　上文提到“Constantly measuring ourselves against others can be an exhausting mind game.(不断地拿自己和别人比较可能是一场令人筋疲力尽的心理游戏。)”强调了与他人比较会带来的负面影响；C选项“In it，we always lose(在这个过程中，我们总是输家)”承接上文，进一步说明了与他人比较的后果，即我们总是会失去一些东西，符合语境。故选C。 2．A　下文提到“I learned the art of seeking inward.At the start of each day，I told myself to love and appreciate myself and give myself confidence instead of looking to others to do that.(我学会了向内寻求的艺术。每天开始的时候，我告诉自己要爱自己，欣赏自己，给自己信心，而不是指望别人这样做。)”表明作者开始寻找内心的平静和自信；A选项“Reset my mind.(重置我的思维)”与下文相呼应，表示作者开始调整自己的心态，重新设定自己的思维模式，以摆脱与他人比较的习惯，符合题意。故选A。 3．E　上文提到“When witnessing my friend's gorgeous and well-organized house，I naturally tended to compare mine with hers.(当看到我朋友漂亮且井然有序的房子时，我自然而然地会拿我的房子和她的比较。)”说明作者有比较的心理；E选项“Feelings of failure instantly arose.(失败的感觉立刻涌上心头)”承接上文，表示作者在比较中感到了失败和不如他人的情绪，同时与后文“ but I've accepted my humanity.(但我已经接受了我的人性)”构成转折，虽然失败感瞬间袭来，但作者已接受自己的不完美。故选E。 4．D　上文提到“I stopped following social media accounts that made me feel inadequate or insecure and set a boundary about my time on those apps.(我停止关注那些让我感到不足或不安全的社交媒体账户，并为我在这些应用程序上的时间设定了界限。)”说明作者开始限制自己在社交媒体上的时间；D选项“Set a timer if you must.(如果你一定要的话，就设个定时器)”与上文相呼应，表示作者建议如果一定要使用社交媒体的话，可以设置定时器来限制使用时间，符合题意。故选D。 5．G　上文提到“I began to train my mind to trust that I did not need to plan，control，and schedule everything.(我开始训练自己的思维，让自己相信我不需要计划、控制和安排一切。)”说明作者开始学会活在当下；G选项“All I needed to do was living in the moment.(我所需要做的就是活在当下)”与上文相呼应，表示作者认为活在当下是最重要的，不需要过于担忧未来或过去，符合语境。故选G。 七选五B4 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 (24－25·高三上山西太原期末)Good posture (体态) is often misunderstood as forcing your spine(脊柱) to stand at attention like a soldier.__1__ It has got some pretty cool curves—a backward curve in your lower back，a forward curve in your upper back，and another backward curve in your neck.Maintaining these natural curves is essential for avoiding unnecessary stress on the muscles. Since posture is not about staying still like a statue，the best posture guidelines encourage movement whenever possible to help maintain comfort throughout the day.Get up，stretch，or move around every thirty to sixty minutes.__2__ In a sitting position，good posture means planting your feet flat on the floor，keeping your knees slightly more than a 90-degree angle，and making sure those natural spine curves stay natural.__3__ Additionally，your shoulders should be back，and your head should be aligned (对齐) with your spine.Bonus tip：using a supportive chair or standing desk can make this whole posture game a lot easier—especially if you're sitting or standing for hours. __4__ It offers several physical benefits，including reducing the risk of injury，relieving muscle tension，improving balance，and increasing energy.It helps keep your bones and muscles in the right position，preventing problems like compressed nerves，injuries from repetitive movements，and pain in the back，neck，and limbs.__5__ Studies show that sitting upright can lift your spirits，cut down stress，and even help you focus better. A．It is a mood booster too. B．However，this is not the truth. C．Proper posture results in long-term well-being. D．Standing properly is as important as sitting correctly. E．Actually，your spine isn't supposed to be poker-straight. F．When standing，distribute your weight evenly on both feet. G．It's like giving your body a mini refresh button to keep your blood flowing. 【语篇解读】　本文是一篇说明文。本文主要讲述了保持良好体态的重要性及其正确做法。 1．E　上文提到“Good posture is often misunderstood as forcing your spine to stand at attention like a soldier.(良好的体态经常被误解为像士兵一样让脊柱挺直站立)”，而下文“It has got some pretty cool curves—a backward curve in your lower back，a forward curve in your upper back，and another backward curve in your neck.(它有一些很酷的曲线——你的下背部向后弯曲，你的上背部向前弯曲，还有你的脖子向后弯曲。)”则描述了脊柱实际上具有一些自然的曲线。因此，这里需要一个转折句来连接上下文，指出上述理解并非事实。E选项“Actually，your spine isn't supposed to be poker-straight.(实际上，你的脊柱不应该像扑克牌一样笔直)”正好起到了这个转折的作用，说明了脊柱并非需要完全挺直，而是有其自然的曲线，符合题意。故选E。 2．G　上文提到“Since posture is not about staying still like a statue，the best posture guidelines encourage movement whenever possible to help maintain comfort throughout the day.(由于体态并非像雕像一样静止不动，因此最佳的体态指南鼓励尽可能多地活动身体，以帮助整天保持舒适)”和“Get up，stretch，or move around every thirty to sixty minutes.(每三十到六十分钟起身、伸展或四处走动)”，这里强调了活动身体的重要性。G选项“It's like giving your body a mini refresh button to keep your blood flowing.(这就像给你的身体按下一个小型刷新按钮，让血液保持流动)”用了一个生动的比喻，进一步解释了定期活动身体的好处，即可以促进血液循环，与上文内容紧密相连。故选G。 3．F　上文“In a sitting position，good posture means planting your feet flat on the floor，keeping your knees slightly more than a 90-degree angle，and making sure those natural spine curves stay natural.(在坐姿中，良好的姿势意味着双脚平放在地板上，膝盖保持90度以上的角度，并确保那些自然的脊柱曲线保持自然)”提到在坐姿中保持良好体态的具体做法，包括双脚平放在地板上、膝盖保持略大于90度的角度等，以确保脊柱的自然曲线得到保持。F选项“When standing，distribute your weight evenly on both feet.(站立时，将体重均匀分布在双脚上)”则转向了站立时的体态要求，与上文的坐姿要求形成对应，同时作为对坐姿要求的一个补充，说明了无论是坐还是站，都需要保持正确的体态。此外，下文提到的“your shoulders should be back，and your head should be aligned with your spine.(你的肩膀应该向后，你的头应该与你的脊柱对齐)”也是站立时体态的一部分，进一步印证了F选项的正确性。故选F。 4．C　下文提到“It offers several physical benefits，including reducing the risk of injury，relieving muscle tension，improving balance，and increasing energy.(它提供了多种身体益处，包括降低受伤风险、缓解肌肉紧张、改善平衡和增加能量)”，这里列举了保持良好体态所带来的身体方面的好处。C选项“Proper posture results in long-term well-being.(正确的体态带来长期的健康)”作为本段的主旨句，概括了保持良好体态对长期健康的重要性。故选C。 5．A　上文“It helps keep your bones and muscles in the right position，preventing problems like compressed nerves，injuries from repetitive movements，and pain in the back，neck，and limbs.(它有助于保持你的骨骼和肌肉在正确的位置，防止神经受压、重复运动造成的损伤、背部、颈部和四肢疼痛等问题)”提到保持正确体态可以帮助骨骼和肌肉保持在正确位置，预防一系列身体问题。A选项“It is a mood booster too.(它还能提升情绪)”则作为对上文内容的补充，指出了保持良好体态除了对身体有益外，还能对情绪产生积极影响。下文“Studies show that sitting upright can lift your spirits，cut down stress，and even help you focus better.(研究表明，坐直可以提升你的情绪，减少压力，甚至帮助你更好地集中注意力)”进一步支持了A选项的观点，说明了正确体态对情绪的具体益处。故选A。 学科网（北京）股份有限公司 $
