Right，the topic of today's lecture is“The Brain”．Well，the brain is an 1.absolutely amazing organ.It consists of grey and white matter.It 2.weighs just over a kilo—just imagine that，like a kilo of potatoes.But this is a very special kilo.It uses 3.twenty percent of the body's energy and it contains over one hundred billion 4.cells. One hundred billion cells! These make up nerve cells，which are connected by 5.electrical impulses.The brain sends messages using electrical impulses，the same way as a computer works.But there are more possible 6.connections in one brain than there are 7.atoms 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? 学生用书第89页 So，what do we know about this 8.organ 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.functions．We now know which parts of the brain are 10.related 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.feelings from it，like pain.Incredible，isn't it? You also have different areas for different kinds of 12.thinking．For example，you have one area for your first 13.language and another area for a foreign language that you learn when you are older.Interesting，isn't it？...But even more interesting than 14.locating different areas of the brain is... Listening to Conversation 9.4，fill in the blanks. (P＝Presenter　K＝Professor Kim　A＝Anna　J＝John　B＝Bella) P：Good morning and welcome to Healthy Living.This morning we're here to discuss the brain.This is Professor Kim，a brain 15.expert．Welcome，Professor. K：Thank you for having me. P：Let's turn to our first caller now.Anna，are you there? What would you like to ask Professor Kim? A：Oh hi，good morning.Yes，I've noticed that my 16.memory isn't as good as it used to be，and I've read about brain 17.exercises—you know，crossword puzzles，games，quizzes，that kind of thing.But do they really work? Should I try them? P：What's your advice，Professor Kim? K：Well，the answer is yes and no.Puzzles and games are good for us to keep our brain 18.active．However，to really exercise the brain，you need to 19.challenge it.That means doing something new，something that perhaps you are not good at.This keeps the brain 20.flexible and helps improve memory. P：So what kinds of activities do you suggest? K：You could try learning a new language，learning to dance or learning to paint...anything that takes you outside your 21.comfort zone． P：Great.Can we have our next caller，please? Hi，John，what's your question，please? J：Oh，hi.I've got some big exams coming up next month，and I was just 22.wondering if there are certain foods that are good for the brain.What do you suggest? K：Great question.Your diet can 23.definitely improve your brain health.If your brain has the correct fuel，it can work at its best.One thing you can do is to cut down on 24.junk food．Foods that help the brain are natural foods：fruit，vegetables，and so on.It might also be a good idea to increase your 25. intake of Omega-3 fats，which are an important brain food.These are found in food like oily fish and eggs. P：Great advice.And finally，can we hear from Bella? B：Oh，hello.My question is about 26.physical exercise.Is there any particular kind of exercise that can improve the health of my brain? What should I do? 学生用书第90页 K：I advise you to do exercise that is good for your heart，such as walking and 27.running．These kinds of exercise increase the 28.amount of oxygen in the blood，which is also good for the brain. P：Fascinating stuff.Join us after the break... 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. 学生用书第91页 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！ 核心词汇练全 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。 (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 container(contain)and mix with water. ②This little book contains(contain)all the information that you need. ③We heard that at least 80 persons were injured，five policemen included(include)． ④Hearing 30 children were poisoned，I was so angry that I couldn't contain myself(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 it contained were a worn-out photo and a business card. [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…… (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 is located(locate)conveniently within the walking distance of the downtown. ②Are you all clear of the location(locate)of your accommodation? ③As it is located on the top of a big hill，the city offers a good view of the ocean. →Located on the top of a big hill，the city offers a good view of the ocean.(动词-ed形式作状语) 学科网（北京）股份有限公司 $
