UNIT 3 Section Ⅰ Welcome to the unit & Reading-【正禾一本通】2025-2026学年高二英语选择性必修2同步课堂高效讲义配套课件（译林版）

UNIT 3　Fit for life 背话题金句，写高分文章 1．Not only can the clubs enrich your knowledge of Chinese traditional culture，but also make your school life colorful and interesting. 俱乐部不仅可以丰富你的中国传统文化知识，也使你的学校生活丰富多彩、有趣。 2．In our life we may meet many failures.As long as we try our best，there is no need to feel regret for these failures. 生活中我们可能会遇到许多失败，但只要我们尽力了，就没有必要为失败而遗憾。 3．While picking oranges，I realized how hard it was for farmers to work in the fields. 在摘橘子的时候，我意识到农民在农田里劳作是多么的辛苦。 4．Equipped with confidence，we can face any challenges and difficulties until we have achieved our goals. 充满自信心，我们可以面对任何困难和挑战，直到我们实现目标。 5．In order to encourage students to take outdoor exercise，our school organized a mountain climbing activity on April 10. 为鼓励学生参加户外锻炼，四月十日我们学校举办了一次爬山活动。 单元话题导入 There are many people who think that wealth is better than health.I used to think so until one day I read a story about Howard Hughes.He was an American billionaire who got anything he wanted.However，in the last twenty years of his life，his health began to deteriorate① and he was miserable.He had the best doctors and nurses. However，he could still find no relief②.I realized that health is worth all the money in the world.If you have millions of dollars but your health is poor，you will not be able to do what you want to do.So I would like to say don't hurt yourself trying to make money.Instead take care of your body and be happy with what you do have.Health is more important.Which is more important，health or wealth？It is a hot topic③ among people.I can hardly answer this question. I didn't realize that health is more important until I saw a businessman's real life. 单元话题导入 A successful businessman，one of my father's friends，devoted himself to④ his business. He works from morning to night every day.There is no weekends in his mind. He often says，“I must earn much money so that I can get what I want.”Lately，he is ill.Though he has a lot of money，he can do nothing but lie in the hospital's bed. So I think health is more important than wealth.People can do nothing if they are always in poor health，let alone happiness.No matter we are rich or not，we can not ignore⑤ the importance of health. 单元话题导入 语篇导读： 　　钱可以买到很多东西，所以很多人认为财富比健康更重要，可如果没了健康，财富还重要吗？ 阅读助手： ①deteriorate vi.恶化，变坏 ②relief n．(疼痛或不快的)减轻，缓解 ③a hot topic 热门话题 ④devote oneself to 献身于，致力于 ⑤ignore vt.忽略，忽视 Section Ⅰ　Welcome to the unit & Reading 内容索引 整体预习 1 语篇理解 2 课时精练 5 夯实双基 3 互动探究 4 整体预习 返回 ①gene n. 基因 ②over the course of在……的过程中 ③game-changing adj.改变游戏规则的(指彻底改变事态发展的) ④genome n．基因组，染色体组 ⑤scientific advance科技进步 原文呈现 名师圈点 The future is in our genes① 　　Good afternoon，ladies and gentlemen.Thank you all for coming to this lecture.Over the course of② my career，I have seen many wonderful scientific developments，but none are as game-changing③ as genome④ editing.I am full of excitement about the possibilities this scientific advance⑤ can bring and I hope to share my excitement with you today.【1】 【1】and连接两个并列句；this scientific advance can bring为省略了关系代词的定语从句，修饰先行词 the possibilities。 ⑥play a critical role in起关键性作用 ⑦shape vt.塑造，影响 ⑧lifespan n．寿命，有效期 ⑨affect vt.影响；侵袭，使感染；深深打动 ⑩contract vt.感染(疾病)；与……订立合同(或契约) n．合同，合约 ⑪virus n．病毒；(计算机程序中的)病毒 原文呈现 名师圈点 　　As many of you may already know，【2】genes play a critical role in⑥ shaping⑦ our lives.Everything from the colour of our eyes to our talent for maths depends on genes.The complete set of genes inside a cell or a living being is called a genome.Our own personal genome carries all the information needed to make us grow and develop.It also contains information that helps determine our lifespan⑧ and affects⑨ our chances of contracting⑩ certain diseases.【3】Some people，for example，carry a gene that makes them more likely to catch a certain virus⑪ or develop a particular form of cancer. 【2】as引导定语从句，as 指代整个句子的内容。 【3】that引导定语从句，修饰先行词 information；and连接两个并列谓语。 ⑫identify vt.找到，发现；确认，认出；显示，说明身份 ⑬relate vi.& vt.联系，使有联系；叙述，讲述 relate to涉及，与……相关 ⑭delete vt.删去，删除 ⑮apply...to...把……应用于…… ⑯a wide range of各种各样的 ⑰restore vt.恢复；修复；使复原，使复位 ⑱vision n．视力，视觉 ⑲ultimately adv.最终，根本上 ⑳fundamental adj.十分重大的，根本的；基础的，基本的 n．基本规律，根本法则，基础 原文呈现 名师圈点 　　Geneticists have been trying to identify⑫ which genes relate⑬ to which diseases，as they believe genome editing is an effective means of disease treatment and prevention【4】．It allows geneticists to make changes to the genome by correcting，adding，deleting⑭ or replacing specific parts of the genetic material. In the near future，geneticists hope to apply this technology to⑮ treat a wide range of ⑯health problems. Soon we may be able to use such treatments to restore⑰ a blind person's vision⑱ or give someone who was born deaf an excellent sense of hearing. Ultimately⑲，this new technology might even make it possible to prevent diseases from ever developing by correcting abnormal genes early on. Genome editing，serving as a new weapon in the fight against diseases，will lead to a fundamental⑳ change in our approach to health care. 【4】as引导原因状语从句，as 意为“因为，由于”。 ㉑at a fast pace快节奏地 ㉒arise vi.发生，出现；(由……)引起，(因……)产生 ㉓restrict vt.限制，限定；束缚，妨碍；约束，管束 ㉔prohibit vt.(尤指以法令)禁止；使不可能 ㉕enhance vt.增强，提高，改善 ㉖resistance n．抵抗力；抵制，反对；抵抗，反抗 ㉗characteristic n．特征，特点 adj.典型的，独特的 ㉘wrestle vi.&vt.奋力对付，努力处理；摔跤 wrestle with努力处理，全力解决 ㉙moral issues道德问题 ㉚figure out计算出；弄清楚，弄明白 原文呈现 名师圈点 　　As the technology continues to develop at a fast pace㉑，【5】however，questions arise㉒ about how to use it appropriately.Should we restrict㉓ our use of this technology to the treatment and prevention of diseases？Should we prohibit㉔ geneticists from using it to enhance㉕ healthy bodies？One day soon we will be able to use genome editing to increase the human resistance㉖ to colds and flu，to make people taller，to help their muscles develop faster，to sharpen all of their senses or to make them more intelligent.We will also be able to select specific characteristics㉗ for children before they are born，creating what some have called“designer babies【6】”．However，is this a good thing？What consequences might it have？Philosophers，geneticists and government officials have all started to wrestle㉘ with such moral issues㉙. 　　We have to figure out㉚ how to keep the technology from running wild. This means putting appropriate controls in place to make sure that genome editing will work to our advantage.Without them，genome editing could be as dangerous as a car out of control. 【5】as引导时间状语从句，as 意为“随着”。 【6】what引导宾语从句，作动词-ing 形式creating的宾语。 ㉛without doubt毫无疑问 ㉜in the history of在……的历史上 原文呈现 名师圈点 　　There is still much to be explored and debated on the subject of genome editing.

Without doubt㉛，genome editing is one of the greatest inventions in the history of㉜ science. Thank you for listening. 译文参考 未来就在我们的基因之中 女士们、先生们，下午好。感谢各位来到本场讲座。在我的职业生涯中，我见证过许多了不起的科研成果，但没有一项能像基因组编辑一样具有颠覆性。我对这项科学进展能够带来的可能性兴奋不已，并且希望在今天与各位分享这份兴奋之情。 在座的很多人可能已经知道，基因对于塑造生命起着决定性作用，从眼睛的颜色到数学天赋，一切都取决于基因。一个细胞或一个生物体内的一套完整的基因就称为一个基因组。每个人自己的基因组都携带着各自生长发育所需的全部信息。基因组包含的信息也有助于决定我们寿命长短并影响我们罹患某种疾病的概率。比如，有些人携带的某个基因会使他们更易感染某种病毒，或是患上某种特定类型的癌症。 遗传学家相信基因组编辑是治疗和预防疾病的一种有效手段，因此他们一直试图找出哪些基因与哪些疾病有关。基因组编辑使得遗传学家可以通过修正、嵌入、移除或替换基因材料的特定部分改变基因组。在不久的将来，遗传学家期待运用这项技术解决多种健康问题。也许我们很快就能用这些疗法帮助盲人恢复视力，或使先天性耳聋患者获得敏锐的听觉。最终，这项新技术甚至有可能通过及早修正异常基因来预防疾病。基因组编辑技术作为对抗疾病的一种新武器，将从根本上改变我们的医疗保健方式。 然而，随着基因组编辑不断迅猛发展，如何恰当地利用这项技术成为了问题。我们是否应该将其应用限制在治疗和预防疾病方面？我们是否应该禁止遗传学家利用它来优化健康的身体？不久之后，我们将能利用基因组编辑技术提高人体对感冒和流感的抵抗力，也能让人长得更高，肌肉生长得更快，让人体的各种感官更加灵敏或者智商更高。我们也将能够在孩子出生前就为他们选择特定的特征，制造出有些人所谓的“设计婴儿”。但这是一件好事吗？会有什么后果？哲学家、遗传学家和政府官员都已着手设法解决这些道德问题。我们必须想办法防止这项技术失控。这意味着我们需要采取恰当的管制措施，以确保基因组编辑对人类有利。否则，它可能会像失控的汽车一样危险。 对于基因组编辑这一话题，要探索和争论的还有很多。虽然公众对这项技术存在争论，但它蕴含的可能性让整个医学界和外界都感到非常兴奋。毫无疑问，基因组编辑是科学史上最伟大的发明之一。感谢各位聆听。 返回 语篇理解 返回 第一步　文本整体理解：理清文章架构 1．What does the text mainly talk about?

A．Deeply grateful. B．Quite concerned. C．A bit sorry. D．Rather frightened. 推理判断题。 根据第二段中的“I later learned that ... as they waited for the ambulance to arrive.”和“I know that ... do not receive CPR within the first six minutes die.”可知，那两名球员通过心肺复苏术救了作者的母亲，因此作者非常感激他们。故选A。 √ 2．In what way did the author's mother change? A．She made efforts to improve CPR. B．She realized the key importance of law. C．She paid more attention to her health. D．She became an active CPR supporter. 细节理解题。根据第三段中的“My mom has used this experience to spread ... their families through a difficult experience.”可知，作者妈妈的变化是她康复后变成了一名积极的心肺复苏术宣传者。故选D。 √ 3．What does Paragraph 4 say about the CPR training for students? A．It may be turned down by a lot of students. B．It requires little time and money. C．It will become a graduation requirement. D．It is difficult and dangerous. 细节理解题。 根据第四段中的“Just one or two days of health class each year will ensure that every student in the state will learn this important skill. This training is also nearly free.”可知，CPR培训花费的时间和费用都很少。故选B。 √ 4．What might the author's mother agree with? A．It is challenging for many students to master CPR skills. B．Every graduate should get an official CPR certification. C．CPR skills are more important than CPR certifications. D．High schools should make a special card for CPR learners. 推理判断题。 根据最后一段中的“This training will not get you the official CPR certification (证书)，but as my mom says，‘You don't need a little card to save someone's life.’”可知，作者的母亲应该会认为，心肺复苏术的技能比这种技术的证书更重要。故选C。 √ B 　　The start of a new school year brings lots of changes.One is the need to wake up earlier. Depending on when school starts，getting up early can turn teens into “zombies(僵尸)，” studies have shown.But when schools start later，teens get to class on time and find it easier to stay awake，a new study finds. 　　For years，researchers and doctors have pushed for later high school start times. Experts recommend kids and teens get an average of nine hours of sleep every day.As children reach their teen years，the clocks inside bodies that control their sleep timing naturally change.This makes it hard for them to fall asleep before 11：00p.m.So when they have to get up in time for an 8：00 a . m. class，they're missing out on valuable sleep time. Knowing this，schools in several places have begun to change their start times. Researchers have now begun looking at how this affects students.When all schools started early，many teens reported struggling to get enough sleep. After the change in start time，students in the late-start schools were less likely to oversleep. Compared to students at the early-start schools，they also were less likely to be late for class.Best of all，they reported felling less sleepy during the day. These changes reflected their getting more sleeping time.That much extra sleep on a daily basis seemed to have made a difference in these students' lives. Researchers believe the extra sleep will make it easier for students to actively take part in school. 　　Sleep is truly important，even though we live in a culture that acts like it's optional(可选择的).It's easier to focus on school，be a good friend and do well in sports when you aren't tired out. 语篇解读　本文是一篇说明文。文章主要介绍了专家建议青少年每天平均睡眠9小时，而由于青少年的身体特征，他们很难早睡，所以这就得需要学校早上晚上课。研究表明，晚上课可以使学生更加积极活跃。 5．Why does the author describe students as “zombies”？ A．Students are inactive for lack of sleep. B．School education makes students stupid. C．Students aren't interested in school at all. D．Teenagers are much quieter than before. 推理判断题。根据第一段中的“Depending on when school starts，... find it easier to stay awake，a new study finds.”可知，学生早起会变成“僵尸”，相反学校如果推迟上课时间，青少年不用起那么早就会更容易保持清醒，所以可以推断出，此处作者将早起的学生描述为“僵尸”，是因为早起的学生会因为缺觉而不活跃，故选A。 √ 6．What do experts think of teenagers' sleeping late as? A．A family rule. B．A personal habit. C．A body characteristic. D．An abnormal behavior. 细节理解题。根据第二段中“Experts recommend kids and teens ... they're missing out on valuable sleep time.”可知，专家认为是由于孩子们进入青春期，控制他们睡眠时间的体内时钟自然发生变化。所以这会导致他们睡觉很晚，由此可知，是青少年的身体特征导致他们睡觉晚，故选C。 √ 7．What advantage does late-start schools have for students? A．Students grow much stronger. B．Students become more active. C．Students go to bed much earlier. D．Students go to school at any time. 细节理解题。根据第三段中的“Best of all，they reported felling less sleepy ... will make it easier for students to actively take part in school.”可知，学校晚上课对学生的一个好处就是使得学生更加积极活跃，故选B。 √ 8．What is the text mainly talking about? A．School starting later makes students active. B．Zombie phenomenon appears in many schools. C．Teenagers should sleep nine hours every day. D．A law should be passed to improve students' health. 主旨大意题。通读全文，尤其是第三段最后“Researchers believe the extra sleep will make it easier for students to actively take part in school.”和最后一段“Sleep is truly important，... when you aren't tired out.”可知，文章主要介绍了专家建议青少年每天平均睡眠9小时，而由于青少年的身体特征，他们很难早睡，所以这就得需要学校早上晚上课。研究表明，晚上课可以使学生更加积极活跃。故选A。 √ Ⅱ.阅读七选五(每小题2.5分，共12.5分) As much as 80 percent of premature heart disease is preventable by making specific lifestyle choices. 1 ．But others may not have crossed your mind.“A small change in your everyday routine can potentially have a big impact in the long run，” says preventive cardiologist (心脏病学家) Dr.Beth Abramson，a spokesperson for the Heart and Stroke Foundation of Canada. 2 ． Engage in volunteer work.Doing good for others helps your self-esteem (自尊) and relieves stress.Research published in Psychosomatic Medicine in 2016 showed that a feeling of purpose in life is linked to a lower likelihood of heart attack and stroke.According to Dr.Arya Sharma，founder of the Canadian Obesity Network and a professor of medicine at the University of Alberta，loneliness is a risk factor for heart health. 3 ．Depending on the type of work you do，volunteering might even increase your physical activity.
