Unit 9 Section Ⅲ Grammar-(配套练习)【精讲精练】2025-2026学年高中英语选择性必修第三册(北师大版)

该高中英语课件聚焦英语时态（如现在完成时、过去完成时等）的综合运用及语篇理解能力，通过单句语法填空夯实基础，过渡到语篇语法填空整合语境，再结合阅读理解、七选五等题型，构建从基础到综合的学习支架，帮助学生衔接前后知识脉络。 其亮点在于采用分层训练（层级一基础语法、层级二综合语用），结合真实话题（如健康生活、AI医学应用），既提升语言能力（语法准确运用与语篇理解），又培养思维品质（分析推断与逻辑梳理）。学生能在语境中掌握时态用法，教师可依托分层设计实现精准教学，提高课堂效率。

[语篇解读]　本文是一篇记叙文。文章主要讲述了作者因为健康问题而决定改变生活方式，并通过结合规律的运动和均衡的饮食来改善健康状况。 1．What made the author decide to change his lifestyle? A．A friend's suggestion. B．Failing a physical test. C．Doctor's warning about his health. D．Seeing an inspiring movie. 解析　推理判断题。根据文章第一段“Last year，I realized I needed to make a change when I couldn't even run for the bus without getting out of breath.My doctor warned me about my rising blood pressure and suggested I adopt a healthier lifestyle.Determined to improve，I decided to combine regular exercise with a balanced diet.(去年，当我连赶公交时跑上几步都会气喘吁吁时，我意识到自己需要做出改变了。我的医生提醒我血压在升高，并建议我养成更健康的生活方式。我下定决心要有所改善，于是决定将规律锻炼和均衡饮食结合起来。)”可知，作者连赶公交跑步都会气喘吁吁，医生警告其血压升高并建议采用更健康的生活方式，之后作者决定改变生活方式，进行锻炼和均衡饮食。故选C。 答案　C 2．How did the author begin his exercise routine? A．By joining a gym. B．With morning walks. C．Through swimming lessons. D．By hiring a personal trainer. 解析　细节理解题。根据文章第二段“I started with simple morning walks，gradually increasing to jogging.(我从简单的晨练散步开始，逐渐增加到慢跑。)”可知，作者开始是进行简单的晨练散步，之后逐渐增加到慢跑。故选B。 答案　B 3．The word “stamina” (Paragraph 2) most likely means ． A．speed B．endurance C．strength D．flexibility 解析　词义猜测题。根据画线单词所在句“At first，it was exhausting，but within weeks I noticed my stamina improving.(一开始，这让我精疲力竭，但几周后我就注意到自己的……在提高。)”可知，一开始锻炼很让人疲惫，但是几周后作者注意到自己的某种能力得到了提升。结合前文作者开始进行锻炼，从简单的晨练散步逐渐增加到慢跑，可推测这里是说锻炼使自己的耐力得到了提高。选项B“endurance”意为“耐力”，符合锻炼后耐力得到提升的语境。故选B。 答案　B 4．What was the most difficult dietary change for the author? A．Eating more vegetables. B．Giving up takeout food. C．Drinking less coffee. D．Avoiding red meat. 解析　细节理解题。根据文章第二段“The most challenging part was cutting down on takeout，but learning to cook simple，nutritious meals made it easier.(最具挑战性的部分是减少外卖食品的摄入，但学会烹饪简单又营养的饭菜让这件事变得容易了些。)”可知，最具挑战性的部分是减少外卖食品的摄入，即放弃外卖食物。故选B。 答案　B B As artificial intelligence(AI) systems become more advanced，we can expect them to be used more often in the world of human medicine and healthcare.AI is designed to imitate the human brain in decision making and learning，so with the computing power to learn tasks in days or even hours，it is possible to create medical AIs that rapidly outperform doctors in certain tasks. Data plays a hugely important role in helping AI systems learn about human medicine.AI systems are trained on large data sets gathered from real­life cases.Providing detailed patient information in quantities is a crucial factor for their success. One of the most important areas for influencing global health is in the field of epidemiology(流行病学).Predicting disease outbreaks can save millions of lives by having resources ready should the worst happen.Startup AIME has successfully combined public health data with machine learning and AI to create a prediction engine capable of anticipating epidemics months in advance with great accuracy. Another field where medical AIs are making rapid advances is in diagnostics(诊断学).Doctors base a lot of decisions on information from X­ray，CT and MRI images.Speeding up diagnoses from patient scans can rapidly improve patient care and outcomes.Computer vision AIs use pattern recognition to work through these images with incredible speed and accuracy.They have been able to outperform junior doctors and even senior specialists in some tests. Cardiologist(心脏病专家) Rima Arnaout developed an AI that beat human experts at correctly interpreting echocardiograms(超声心动图) by 92 percent to 79 percent.She said that despite the result there is no prospect of AI replacing human doctors any time soon.“As cardiologists，we read the images and then go to see the patient，” she said.“So we're both reading images and practicing medicine.I don't think that the second piece will be taken over so quickly.” The acceptance of AI in medicine will continue to gather pace in the future as it becomes more widespread. [语篇解读]　本文是一篇说明文。文章介绍了人工智能(AI)系统在人类医学领域的应用。 5．What plays a big role in helping AI systems know of human medicine? A．Certain task. B．Large data. C．The skill to imitate. D．The increasing demand. 解析　细节理解题。根据第二段第一句可知，在帮助人工智能系统学习人类医学方面，大数据发挥了重要作用。故选B。 答案　B 6．Why is Startup AIME mentioned in paragraph 3? A．To illustrate predicting disease is possible. B．To call on doctors to focus on public health data. C．To prove it's a successful company in global health. D．To let readers realize the importance of early success. 解析　推理判断题。根据第三段最后一句可知，Startup AIME已经成功研发出可以提前几个月较准确地预测流行病的AI系统，由此可推知，这里提到Startup AIME是为了说明预测疾病是可能的。故选A。 答案　A 7．What do we know about computer vision AIs? A．They do better than doctors in some tests. B．They speed up diagnoses from patient scans. C．They can rapidly improve patients'conditions. D．They analyze information from X­ray，CT and MRI images. 解析　细节理解题。根据第四段最后两句可知，计算机视觉人工智能在一些测试中比医生表现得更好。故选A。 答案　A 8．What do Rima Arnaout's words in paragraph 5 imply? A．AIs are not so smart as human doctors. B．It's not easy for AIs to take the place of human doctors. C．A cooperation between AIs and human doctors is a must. D．Human doctors are playing a big role in practicing medicine. 解析　推理判断题。根据第五段中Rima Arnaout说的话可推断，Rima Arnaout认为尽管AI在诊断环节表现更好，但AI不可能轻易取代人类医生，尤其是在治疗环节。故选B。 答案　B Ⅱ.七选五 While no one can avoid all stress，you can work to handle it in healthy ways that increase your potential to recover. Eat and drink to improve your health.Some people try to reduce stress by drinking alcohol or eating too much. 1 But actually these may add to stress in the long run.Caffeine also can worsen the effects of stress.Consuming a healthy，balanced diet can help to prevent stress.

Reduce triggers(触发) of stress.If you are like most people，your life may be filled with too many demands and too little time. 4 You can free up time by practicing time­management skills like asking for help when it's appropriate，setting priorities，pacing yourself，and reserving time to take care of yourself. Study and practice relaxation techniques.Taking the time to relax every day helps to manage stress and to protect the body from the effects of stress.You can choose from a variety of techniques.These include deep breathing，imagery，progressive muscle relaxation，and mindfulness meditation.There are many online and smartphone apps that provide guidance on these techniques. 5 A．Examine your values and live by them.
