The solution,according to Schwartz,is not to eliminate choice but to learn how to manage it.He suggests becoming a \"satisficer\"rather than a \"maximizer.\"A maximizer seeks the absolute best option, spending countless hours researching and comparing,only to end up feeling regret.A satisficer,in contrast,sets clear criteria for what is \"good enough\"and settles for the first option that meets those standards.Satisficers tend to be happier because they are not constantly haunted by the possibility of a better deal Furthermore,the sheer volume of decisions we face daily can lead to \"decision fatigue,\"a state where our ability to make sound judgments deteriorates after a long session of decision-making.The key, therefore,is to prionitize our decisions.We should reserve our mental energy for significant life choices- like where to live or whom to many-and automate or simplify the trivial ones,such as what to wear.By consciously limiting our options and embracing \"good enough,\"we can reclaim our time,reduce our anxiety,and ultimately,feel more satisfied with the lives we choose. ()1.What is the \"paradox of choice"as described in the passage? A.The fact that having more freedom makes people happier. B.The idea that excessive options can cause negative feelings. C.The belief that all choices are equally important. D.The difficulty in finding a job in a modern society. ()2.Why can buying a pair of jeans be a \"stressful exercise\"today? A.Because jeans are more expensive than before. B.Because there are too many similar options to compare. C.Because shoppers are too lazy to make a decision. D.Because salespeople are less helpful than in the past. ()3.According to Schwartz,a \"satisficer\"is someone who A.always looks for the best possible option B.spends a lot of time researching before buying C.is satisfied with an option that is \"good enough\" D.often regrets the choices they have made ()4.What does the author suggest to deal with \"decision fatigue\"? A.To avoid making any decisions at all. B.To simplify decisions that are not very important. C.To spend more time on small decisions. D.To consult a professional for every choice. Passage B The air is crisp and carries the scent of damp earth and decaying leaves.Sunlight filters through the canopy of ancient oaks and maples,painting a mosaic of light and shadow on the forest floor.This is not a scene from a remote national park,but from the Mianus River Gorge Preserve in New York,a place saved from development by a pivotal choice made in the 1960s. This 1,000-acre haven of old-growth forest stands as a testament to the power of collective action.In the mid-20th century,much of the American Northeast was undergoing rapid suburbanization.The Mianus River Gorge,a pristine area of incredible ecological importance,was at risk of being carved up for housing developments.A small group oflocal residents,scientists,and conservationists foresaw the irreversible damage that would result.They did not just talk about the problem;they formed an organization to raise funds and purchase the land.Their monumental choice to act,rather than lament, ensured that this living museum of biodiversity would be preserved for future generations. Their success was not just about saving trees.The choice to protect the gorge had cascading positive effects.The watershed,which provides drinking water for millions downstream,remained clean and healthy.Native species,from the barred owl to the red-backed salamander,continued to thrive.The preserve became an outdoor classroom,offering city dwellers a rare chance to connect with nature.It also served as a living laboratory for scientists studying climate change and ecosystem dynamics.The initial choice,driven by a sense of responsibility and long-term vision,created a ripple effect of benefits that continue to unfold decades later. In a world that often encourages us to think short-term,the story of the Mianus River Gorge is a powerful counter-nairative.It reminds us that the choices we make,especially those concerning our shared environment,have profound and lasting consequences.They can prevent a piece of wilderness from being lost forever,protect a vital resource,and create a legacy for our children and our children's children. The question before each generation remains the same:what choices will we make to shape the world we want to inherit? ()1.What is the main purpose of the Mianus River Gorge Preserve? A.To serve as a site for residential development. B.To provide drinking water for New York City C.To protect a natural area from being destroyed. D.To create a park for outdoor concerts and events ()2.The underlined word "pivotal\"in paragraph 1 is closest in meaning to A.risky B.critical C.difficult D.random ()3.Which of the following is NOT mentioned as a benefit of preserving the gorge? A.Ensuring a clean water supply B.Providing a site for scientific research. C.Increasing local property values. D.Protecting a habitat for wildlife. ()4.What is the author's attitude towards the choice made by the conservationists? A.Critical. B.Neutral C.Admiring. D.Doubtful ()5.What message does the story of the Mianus River Gorge convey? A.Individual choices have little impact on the environment. B.Collective action can lead to long-term positive outcomes. C.Economic development is always more important than nature. D.Only scientists and experts should make environmental decisions. 二、完形填空 I had a tough decision to make last summer.My best fiend,Leo,was moving to another city and invited me to spend his final weekend with him at a music festival.I was (1) about it,but there was a problem.The same weekend,my grandfather,who lives far away,was(2) a special award for his lifelong community service.He had asked me to be there to see him receive it.

The concept of a\"gap year\"-a break taken by students between high school and university-has become increasingly popular worldwide.Far from being a simple holiday,a well-planned gap year can be a transformative experience.It provides a crucial window for young people to step outside the familiar structure of academic life and into the broader world,forcing them to make independent choices that shape their character and future. Proponents argue that the benefits are immense.Firstly,a gap year offers invaluable opportunities for personal growth.By navigating unfamiliar environments,whether it's teaching English in a remote village or volunteering on a conservation project,students develop resilience,independence,and problem- solving skills that cannot be taught in a classroom.The necessity of making choices-from planning a travel budget to handling a cultural misunderstanding-builds confidence and maturity.Secondly,it provides clarity of purpose.Many students enter university feeling burnt out or uncertain about their chosen field.A gap year can offer a "reset button,"allowing them to explore different interests,gain practical experience,and return to their studies with renewed focus and motivation.For example, someone interested in medicine might volunteer at a healthcare clinic,confirming their passion before committing to years of study However,a gap year is not without its detractors.Critics point to the significant financial cost and the potential for it to become a \"lost year"without proper planning.Some students may find it difficult to readjust to academic discipline after a year of relative freedom,and there is a risk that the momentum of learning can be lost.Furthermore,the experience is undeniably a privilege not accessible to everyone, which can be a source of social inequality. Despite these concems,when approached with careful thought and clear goals,the choice to take a gap year can be one of the most significant and rewarding decisions a young person makes.It shifts the focus from passive learning to active living,equipping them not just with knowledge,but with the wisdom to use it. 1.According to the passage,what is a "gap year"and why is it more than just a holiday? 2.List two ways a gap year can help with personal growth,as mentioned in the passage. 3.How can a gap year provide "clarity of purpose"for students? 4.What are two main criticisms or risks associated with taking a gap year? 5.What is the author's overall view on the choice of taking a gap year? 四、短文填空 根据上下文，在空白处填入1个适当的单词或括号内单词的正确形式。 Making an informed choice often means looking beyond the immediate and obvious.This is particularly true when it comes to our food.The phrase \"you are what you eat\"is more than just a saying,it is a reminder that each meal is a choice that (1) affects our health and the planet. Consider the simple(2)between a locally grown apple and one imported from thousands of miles away.The former supports local farmers,requires less fuel for(3) ,and is often fresher. The latter offers variety but at an environmental cost.(4)we are not always aware of the background of our food,we(5)make a conscious effort to learn.Reading labels,(6) the season of produce,and choosing more plant-based meals are all small choices that add up Sometimes,the best choice requires us to resist marketing.A product(7)as \"healthy\"may be full of sugar and artificial ingredients.(8) ,a \"quick fix\"solution for a problem might create more issues later.The ability to analyze information and question sources is a skill worth (9) This not only applies to food but to all aspects of life,from(10) career we pursue to the news we consume. Ultimately,every choice reflects our values.By being more thoughtful about the decisions we face,we can steer our lives in a direction that is not only good for us but also for the world we share. 1. 2 3. 4. 5. 6. 7. 8. 9. 10. 五、写作 假设你是李华，你的朋友林涛来信说他暑假面临一个选择：是参加一个为期一个月的国际学生 交流项目（去英国学习英语与文化），还是去一家知名的科技公司做实习生。他认为两者都很 有价值，但时间上只能选其一。请你给他回信，内容包括： 1.表明你理解他的困境： 2.分析两种选择的利弊（各至少一点)； 3.给出你的建议及理由。 注意： 1.词数100左右； 2.可以适当增加细节，以使行文连贯： 3.开头和结尾已为你写好，不计入总词数。 Dear Lin Tao, I'm glad to hear from you and I fully understand the dilemma you're facing Yours, LiHua 参考答案 PassageA:1.B 2.B 3.C4.B;Passage B:5.C6. 一、 阅读理解 B7.C8.C9.B 1.A2.C3.B4.D5.A6.B7.B8.C9.D10.B 二、完形填空 11.C12.A13.D14.C15.B 三、阅读短文回答问题 1.A gap year is a break taken by students between high school and university.It is more than just a holiday because it provides a crucial window for personal growth and forces young people to make independent choices that shape their character and future 2.It helps develop resilience,independence,and problem-solving skills.It also builds confidence and maturity 3.It provides clarity of purpose by allowing students to explore different interests,gain practical experience,and retumn to their studies with renewed focus and motivation. 4.The significant financial cost and the potential for it to become a\"lost year"without proper planning.

On the one hand,the exchange program in the UK would be a great chance to improve your English and immerse yourself in a different culture.This experience could broaden your horizons and make you more independent.On the other hand,the internship at a top tech company would give you valuable,hands-on experience in a professional environment,which looks excellent on a resume. Considering your major,computer science,I think the internship might be more beneficial for your career prospects.Practical work experience is highly valued by employers these days.You can always travel or study abroad later,but this specific internship opportunity may not come again. Whatever you choose,I wish you all the best! Yours, LiHua
