These make up nerve cells，which are connected by 5. impulses.The brain sends messages using electrical impulses，the same way as a computer works.But there are more possible 6. in one brain than there are 7. in the universe.Just think about that again.There are more possible connections in your brain than there are atoms in the universe.Amazing，isn't it？ Makes a normal computer look simple，doesn't it？ electrical connections atoms So，what do we know about this 8. called“the brain”？ Scientists who study the brain have learnt a lot about it in the last ten years.Like explorers exploring the world，they've found that there are different areas in the brain and these areas are responsible for different 9. ．We now know which parts of the brain are 10. to different parts of our body and feelings from them.A good example of this can be seen in people who have lost an arm or a leg in an accident.Though they don't have an arm or a leg，they can still have 11. from it，like pain.Incredible，isn't it？ organ functions related feelings You also have different areas for different kinds of 12. ．For example，you have one area for your first 13. and another area for a foreign language that you learn when you are older.Interesting，isn't it？...But even more interesting than 14. different areas of the brain is... thinking language locating Listening to Conversation 9.4，fill in the blanks.

P：Fascinating stuff.Join us after the break... running amount Step Ⅲ 　Post listening 听力技巧点拨——抓关键信息 在英语听力考试中，提出意见或征求建议的题型十分常见。以下是“常见问法及应对策略”的系统总结，帮助您快速识别和解答这类题目： 一、听力中常见的征求意见/建议的问法 1．直接征求意见 What do you think(about)...？ 你觉得……怎么样？ How do you feel about...？ 你对……有什么看法？ What's your opinion on...？ 你对……的意见是什么？ 2．直接征求建议 What should I do(about)...？ 我该怎么做……？ Can you give me some advice on...？ 你能给我一些关于……的建议吗？ Do you have any suggestions for...？ 你对……有什么建议吗？ 3．间接征求建议(隐含需求) I'm having trouble with... 我在……方面遇到困难。→隐含需要建议 I'm not sure whether to... 我不确定是否要……→隐含需要意见 Do you think it's a good idea to...？ 你觉得……是个好主意吗？ 二、听力中常见的回答方式 1．给出建议的句型 明确建议： You should.../Why don't you...？ 你应该……/你为什么不……？ I recommend.../It might be better to... 我建议……/……可能更好。 委婉建议： Have you considered...？ 你考虑过……吗？ If I were you，I'd... 如果我是你，我会…… 2．表达意见的句型 同意：I agree(that).../That's a good point. 不同意：I'm not sure about that.../Actually，I think... 中立态度：It depends on.../There are pros and cons... 三、处理这类试题的解题技巧 1．预判问题类型 听到“What do you think...？”或“What should I do？”等信号词时，立刻预判接下来会涉及建议或意见。 2．抓关键回答词 一则，重点听should/could/recommend/suggest等词后的内容，答案常在此处；二则，注意转折词(如but/however)，后面可能是否定或修正意见。 3．排除干扰项 选项中若出现与对话无关的具体细节(如时间、地点)，通常是干扰项。正确答案往往是对问题的直接回应，而非旁支信息。 4．例题分析 听力原文： W：I can't decide whether to take the job in New York or stay here. M：Well，the salary is higher in New York，but the cost of living is too.Have you considered the work-life balance？ 问题：What does the man suggest？ 正确选项： Think about lifestyle factors，not just salary. 四、常见陷阱 ①答非所问：回答未针对问题核心(如问意见却回答事实)。 ②过度推断：选项添加了原文未有的结论。 ③部分正确：只截取对话片段，忽略否定词(如“but it's not worth it”)。 通过熟悉这些问法、回答模式及解题技巧，您能更高效地应对听力中的意见/建议类题目。练习时注意总结高频句型，强化信号词敏感度！ 返回 提能力 语基讲练 返回 contain vt.包含，容纳，装盛 (教材原句)The brain contains about one billion cells.大脑包含约十亿个细胞。 核心词汇练全 1 归 纳 (1)contain vt.　　　 克制；控制 contain oneself　　　　 克制自己 (2)container n.　　　　 容器 单句语法填空/补全句子/完成句子 ①Put a small amount of powder into a (contain)and mix with water. ②This little book (contain)all the information that you need. ③We heard that at least 80 persons were injured，five policemen___________ (include)． ④Hearing 30 children were poisoned，I was so angry that I couldn't (控制我自己)． ⑤好奇心促使我把手伸入钱包，但里面只有一张破旧的照片和一张名片。 Curiosity led me to dig in the wallet，but the only other things _____________ were a worn-out photo and a business card. container contains included contain myself it contained 辨析比较　contain/include 易混词 辨析 contain 意为“包含；含有”，侧重于“整体内有”，也可指在某一范围或容器内能容纳某物，不用于进行时态。 include 意为“包括”，侧重于被包含者只是整体中的一部分。 locate vi.&vt.找出……的准确位置 (教材原句)But even more interesting than locating different areas of the brain is... 但比定位大脑的不同区域更有趣的是…… 2 归 纳 (1)be located in/on/at　 位于；坐落于 (2)locate vt.　　　　 把……安置在(或建造于) (3)location n.　　　　 地点；位置 单句语法填空/句式转换 ①Your hotel (locate)conveniently within the walking distance of the downtown. ②Are you all clear of the (locate)of your accommodation？ ③As it is located on the top of a big hill，the city offers a good view of the ocean. → ，the city offers a good view of the ocean.(动词-ed形式作状语) 返回 is located location Located on the top of a big hill 课时测评 返回 维度一　根据汉语及首字母提示填入单词的适当的形式(每小题1分，共8分) 1．Try to avoid foods which (包含)a lot of fat. 2．The area has been declared a disaster (地区)． 3．All day she had fought off the (冲动)to telephone her boss. 4．Each bone is an (器官)with certain shape，structure and function. 5．One chocolate bar like this is equal to a large meal in calorie (摄入量)． 语境基础练 contain zone impulse organ intake 6．All substances，whether they are gaseous，liquid or solid，are made of (原子)． 7．Quizzes and (纵横字谜)puzzles can be great ways to stimulate your brain. 8．N cells transmit electrical signals throughout the body at a high speed. atoms crossword erve 维度二　单句语法填空(每小题1分，共5分) 1．The hotel is centrally (locate)for all major attractions. 2．Food will last longer if kept in an airtight (contain)． 3．There's (absolute)nothing more the doctors can do. 4．What's the (connect)between bird and dinosaur behavior？ 5．Most of us need to lead more balanced lives to be (health)and happy. located container absolutely connection healthy 维度三　完成句子/同义句转换(每小题4分，共12分) 1．虽然困难重重，但没有什么比通过挑战自己所获得的成就感更有价值了。(as...as...)

If you have a camera stand，that's great; otherwise，try to get someone to take your photos—don't worry，he or she doesn't have to be a professional photographer! Choose a well-lit area in front of a plain wall.The simpler the background is，the more attention will be on you and your transformation. Dress Code (密码) A swimsuit or form-fitting workout clothes work best.You should show as much of your body as you're comfortable with，but please keep it appropriate for public consumption. Photo Composition Take full-body photos and make sure your face can be clearly seen. Try to take the photos from different angles，such as a front view and a side view. Whatever you do，consistency is key! Ideally，your “before”and“after”photos will show you doing the same poses，wearing the same clothes，in the same place both before and after your transformation.This way，your body is the only thing that can be seen changing. Timing Make sure to take the photos at the beginning，during，and end of your program so that you can see your progress over time.If you're doing a 90-day program，for example，you could take photos on Day 1，and then on Day 30，Day 60，and Day 90 until you're done. 语篇解读　本文是一篇应用文。文章详细介绍了拍摄高质量“前后”对比照片的实用指南，包括设备选择、着装要求、拍摄构图及时间规划等要素，旨在帮助读者有效记录身体变化过程。 1．What is the aim of a set of“before”and“after”photos？ A．To record a touching story. B．To remember a trip. C．To share a workout method. D．To show a transformation. √ 细节理解题。 根据第一段“Suppose you're about to start a weight-loss or body-shaping journey that will change your body and your life，nothing shows the results of this experience better than a set of‘before' and ‘after' photos.”可知，(拍摄)一组“之前”与“之后”的对比照片的目的是展示你的改变。故选D项。 2．What is needed before taking“before”and“after”photos？ A．A plain setting. B．A fashionable dress. C．A high-tech camera. D．A well-trained photographer. √ 细节理解题。根据Camera，Photographer，and Location部分的“Choose a well-lit area in front of a plain wall.The simpler the background is，the more attention will be on you and your transformation.”可知，在拍摄“之前”与“之后”的对比照片之前需要一个不加修饰的背景。故选A项。 3．Which of the following can probably guarantee high-quality “before” and “after” photos？ A．Taking photos every day. B．Adopting a unique angle. C．Making your face visible. D．Wearing a consistent smile. √ 细节理解题。根据Photo Composition部分的“Take full-body photos and make sure your face can be clearly seen.”可知，拍摄全身照并确保面部清晰可见大概率可以保证获得高质量的“之前”与“之后”的对比照片。故选C项。 B (2025·安庆一中模拟考) If you've ever found yourself scratching(挠)your head over a decision when the answer is obvious，now there's a scientific reason behind it.“The problem is‘decision fatigue'—a psychological phenomenon that influences the quality of your choices after a long day of decision-making，causing indecision or poor choices，”says Evan Polman，assistant professor of marketing at the Wisconsin School of Business. Physicians who have been on the job for several hours，for example，are more likely to prescribe antibiotics(开抗生素)to patients when it's unwise to do so.“Probably it's because it's simple and easy to write a prescription and consider a patient case closed rather than investigate further，”Polman says. But interestingly，decision fatigue won't be an issue when you're making choices on another's behalf.By taking upon the role of adviser rather than decision maker，one does not suffer the consequences of decision fatigue.It's as if there's something fun and relieving about making someone else's choice. Getting the best advice，however，will rely on the personality of your adviser.Surprisingly，the best person to ask is someone relatively cool-headed to your circumstances; someone who doubts others and thinks highly of themselves.That's because a person who cares deeply about others can also suffer from decision fatigue when advising others，presenting the potential for bad advice.“For example，research has found that nurses who are particularly high in sympathy experience career burnout more often than nurses who are less sympathetic，”Polman says. Getting input from others not only offers a fresh perspective and thought process，but it often also includes riskier choices.While this sounds undesirable，it can be quite good.“People with decision fatigue will likely choose to go with the current situation，while a change in the course of action can sometimes lead to a positive outcome.”he says.“That's not to say that risk is always good，but it is related to taking action while decision fatigue certainly leads to inaction.” 语篇解读　本文是一篇说明文。文章主要介绍了决策疲劳的心理现象、其影响及如何通过他人建议缓解这一问题。 4．Which of the following is an example of decision fatigue？ A．A lawyer makes weaker judgments after a day of cases. B．A manager approves a project without thorough review. C．A chef follows the usual recipe to make an evening meal. D．A physician advises a patient to drink water after check-up. √ 推理判断题。根据第一段可知，决策疲劳是一种在长时间决策后影响选择质量，导致优柔寡断或糟糕选择的心理现象。A选项中“一名律师在处理了一天的案件后做出了较弱的判断”，符合长时间决策后出现判断质量下降的情况，是决策疲劳的例子。故选A。 5．When do people experience less decision fatigue？ A．When they take decision shortcuts. B．When they guide others' decisions. C．When they encounter major choices. D．When they have advisers to turn to. √ 细节理解题。根据第三段中“But interestingly，decision fatigue won't be an issue when you're making choices on another's behalf.By taking upon the role of adviser rather than decision maker，one does not suffer the consequences of decision fatigue.”可知，当人们指导他人的决策时，经历的决策疲劳较少。故选B。 6．What makes a better adviser according to the text？ A．Experience in giving advice. B．Deep sympathy for others. C．Particular nursing professions. D．Less emotional involvement. √ 推理判断题。根据第四段中“Surprisingly，the best person to ask is someone relatively cool-headed to your circumstances; someone who doubts others and thinks highly of themselves.”可推知，情感卷入较少的人能成为更好的顾问。故选D。 7．What does Polman say about taking risks in decision-making？ A．It often ends in regret. B．It promotes taking action. C．It encourages creativity. D．It causes serious consequences. √ 推理判断题。根据最后一段中“That's not to say that risk is always good，but it is related to taking action while decision fatigue certainly leads to inaction.”可推知，波尔曼认为在决策中冒险能促进采取行动。故选B。 Ⅱ.完形填空(每小题1分，共15分) (2025·成都一中4月月考) Whenever my child caused me to change my schedule，I thought to myself，“We don't have time for this.”__1__，the two words I most commonly spoke to my child were：“Hurry up.”But my promise to __2__ was made almost three years ago，and I began my journey to grasp what matters in life.My younger daughter is my living __3__ of why I must keep trying.In fact，the other day，she reminded me once again.
