Unit 4 Our Memory Section B (2a-Reflecting) 课件 2026-2027学年人教版英语九年级上册

该初中英语课件围绕“Our Memory”主题，聚焦核心词汇（如increase、wound）、词缀构词规律（前缀改义、后缀改性）及记忆策略，通过词根扩展练习导入，衔接Billy日记阅读提取关键信息，搭建“词缀学习—阅读分析—策略迁移—写作实践”的学习支架。 其亮点在于以核心素养为导向，通过词根词缀归纳培养思维品质中的逻辑分析能力，借助“制订计划—执行追踪—日记反思”闭环模式提升学习能力，结合动物记忆科普短文渗透文化意识。如词缀练习从act派生出react、action等，日记写作提供结构模板，助力学生语言运用与策略内化，也为教师提供系统教学路径。

Section B (2a-Reflecting) Unit 4 Our Memory 01 Teaching Objectives 语言能力:学生掌握 increase、blood、wound、divide、recognize、outline 等核心词汇的音形义及短语搭配;通过词缀构词练习掌握前缀改变词义、后缀改变词性的规律,并能据此从 act、forget、effect 等词根扩展词汇量;读懂Billy关于演讲记忆方法的日记,提取关键信息;运用相关语言点完成句子填空与动物记忆语篇填空;仿照Billy日记格式撰写个人记忆挑战日记。 思维品质:学生通过词根词缀归纳构词规律,培养分类对比与逻辑分析能力,理解"前缀改义、后缀改性"的本质区别;阅读Billy日记时梳理"挑战—目标—方法—结果"叙事逻辑,分析三种记忆策略的适用场景与内在关联;在3b制定个人记忆计划时,需辩证思考自身记忆短板并选择最适合的方法;在 Reflecting 环节回顾单元所学,进行批判性自我评价,发展元认知与反思性思维能力。 学习能力:学生运用词缀法这一核心词汇学习策略,由已知词根推导生词词义与词性,提升词汇自主习得效率;通过阅读Billy日记学习"创建纲要—关键词联想—分块练习—保持自信"的演讲记忆法,并迁移至实际学习场景;3b至3c环节以"制订计划—执行追踪—日记反思"的闭环模式进行自我监控与学习管理;Reflecting 环节引导学生回顾本单元知识体系,养成定期反思与动态调整学习策略的习惯。 文化意识:学生通过科普短文了解松鼠储食、大雁迁徙、海豚辨声等自然中的记忆奥秘,感受科学探索精神与生命智慧;从Billy克服演讲焦虑的经历中体会"方法比努力更重要"的学习理念,认识到找到适合自己的学习策略是个人成长的关键;通过制定个人记忆计划与同伴分享交流,尊重学习方法的多样性;Reflecting 环节引导学生在自我反思中树立科学用脑、高效学习、勇于实践的积极价值观。 02 Teaching Points 教学重点:掌握 increase、blood、wound、divide、recognize等核心词汇的音形义及 divide sth into 短语搭配;理解并运用词缀构词规律,能从 act、forget、effect 三个词根派生出 react、action、active、forgetful、forgettable、effective、effectively 等新词;在语境中正确运用keep in mind、run out、happen to、go through 等语言点完成句子填空与动物记忆语篇填空;读懂Billy日记并提取三种记忆方法关键信息;完成3b记忆计划表格与3c日记写作。 教学难点:掌握increase名词与动词的重音区分及词性转换运用;在语境中准确判断词缀派生词的词性与词义并选择正确形式完成填空;one-size-fits-all等复合词的理解与灵活运用;将Billy日记中的记忆策略迁移至个人实际学习场景,制定切实可行而非泛泛而谈的记忆挑战计划;用英语完整撰写记忆挑战日记,做到结构清晰、语言连贯、方法具体、反思有深度;在Reflecting环节中用英语进行有深度的自我评价与学习策略调整反思。 03 Section B (2a-3c) unforgettable Use affixes to create as many new words as possible. Use your dictionary. act re- -ion -ive -or forget -ful -able -ness un- react action active actor forgetful forgetfulness forgettable effect -ive effective effectively effectiveness -ly -ness 词缀 一、什么是词缀? 英语单词并不是凭空出现的,它们大多由「词根 + 词缀」组合而成。词缀是加在词根上、用来改变单词含义或词性的那部分字母组合。就像中文里的「偏旁部首」一样,掌握了词缀,我们就能「望词生义」,遇到生词也能猜出个大概。 词缀分为两大类:一类叫「前缀」,加在单词前面,主要用来改变单词的意思;另一类叫「后缀」,加在单词后面,主要用来改变单词的词性(比如把动词变成名词、把形容词变成副词等),有时也会改变意思。 二、常见前缀 1. un- 表示「不、非、相反」(加在形容词、副词前面) 词缀 happy(高兴的) unhappy 不高兴的 lucky(幸运的) unlucky 不幸的 usual(平常的) unusual 不寻常的 able(能干的) unable 不能的 friendly(友好的) unfriendly 不友好的 true(真实的) untrue 不真实的 2. dis- 表示「不、否定、相反」(多加在动词、形容词前面) like(喜欢) dislike 不喜欢 agree(同意) disagree 不同意 appear(出现) disappear 消失 honest(诚实的) dishonest 不诚实的 believe(相信) disbelieve 不相信 3. in- / im- / il- / ir- 表示「不、非」 in- 加在大多数字母前,如 in + correct = incorrect(不正确的)。 词缀 im- 加在以 b、m、p 开头的词前,如 im + possible = impossible(不可能的)、im + polite = impolite(不礼貌的)。 il- 加在以 l 开头的词前,如 il + legal = illegal(非法的)。 ir- 加在以 r 开头的词前,如 ir + regular = irregular(不规则的)。 记忆口诀:b、m、p 前用 im;l 前用 il;r 前用 ir;其余用 in。 4. re- 表示「再、有一次、重新、回」(加在动词前) write(写) rewrite 重写 build(建造) rebuild 重建 turn(转) return 返回、归还 use(使用) reuse 重复使用 tell(告诉) retell 复述 cycle(循环) recycle 回收利用 词缀 5. pre- 表示「在……之前、预先」 view(看) preview 预览 pay(支付) prepay 预付 pare(准备) prepare 准备 history(历史) prehistory 史前 6. mis- 表示「错误、误」 understand(理解) misunderstand 误解 take(拿) mistake 弄错 7. over- 表示「过度、过分、在上方」 weight(重量) overweight 超重的 work(工作) overwork 过度工作 time(时间) overtime 加班 come(来) overcome 克服 8. under- 表示「在……下面、不足」 词缀 ground(地面) underground 地下的 water(水) underwater 水下的 9. inter- 表示「在……之间、相互」 national(国家的) international 国际的 view(看) interview 面试、采访 10. 其他常见前缀 sub- 表示「在下面、次」 subway 地铁(地下的路) subtitle 副标题、字幕 super- 表示「超级、超过」 supermarket 超市 superman 超人 auto- 表示「自己、自动」 词缀 autograph 亲笔签名 automatic 自动的 bi- 表示「双、两」 bicycle 自行车(两个轮子) bilingual 双语的 fore- 表示「在前面、预先」 forehead 前额 foresee 预见 ex- 表示「前任、向外」 ex-husband 前夫 export 出口 三、常见后缀 (一)名词后缀:把别的词变成名词 词缀 1. -er / -or 表示「做某事的人」 play(玩) player 选手、运动员 act(表演) actor 演员 direct(指导) director 导演、主任 visit(访问) visitor 访问者 2. -ist 表示「从事……的人、……家」 art(艺术) artist 艺术家 science(科学) scientist 科学家 piano(钢琴) pianist 钢琴家 tour(旅游) tourist 游客 3. -ian 表示「……的人」 music(音乐) musician 音乐家 history(历史) historian 历史学家 4. -ment 把动词变成名词 词缀 develop(发展) development 发展 move(移动) movement 运动 agree(同意) agreement 协议、同意 punish(惩罚) punishment 惩罚 5. -ness 把形容词变成名词 happy(高兴的) happiness 高兴 sad(悲伤的) sadness 悲伤 ill(生病的) illness 疾病 kind(善良的) kindness 善良 6. -tion / -sion 把动词变成名词 educate(教育) education 教育 inform(通知) information 信息 invent(发明) invention 发明 pollute(污染) pollution 污染 7. -ity 把形容词变成名词 词缀 able(能干的) ability 能力 possible(可能的) possibility 可能性 8. -th 构成名词 true(真实的) truth 真相 grow(生长) growth 生长 heal(治愈) health 健康 long(长的) length 长度 9. -ing 构成动名词(名词) meet(见面) meeting 会议 build(建造) building 建筑物 (二)形容词后缀:把别的词变成形容词 1. -ful 表示「充满……的、有……的」 help(帮助) helpful 有帮助的 use(使用) useful 有用的 词缀 2. -less 表示「无、没有」 help(帮助) helpless 无助的 use(使用) useless 无用的 care(小心) careless 粗心的 home(家) homeless 无家可归的 3. -y 表示「有……特征的、充满……的」 -sun(太阳) sunny 阳光充足的 cloud(云) cloudy 多云的 rain(雨) rainy 多雨的 wind(风) windy 多风的 4. -al 表示「……的」 nation(国家) national 国家的 nature(自然) natural 自然的 education(教育) educational 教育的 person(人) personal 个人的 词缀 5. -able / -ible 表示「可……的、值得……的」 comfort(舒适) comfortable 舒服的 enjoy(享受) enjoyable 令人愉快的 6. -ous 表示「具有……的」 danger(危险) dangerous 危险的 humor(幽默) humorous 幽默的 7. -ive 表示「有……倾向的」 act(行动) active 活跃的 create(创造) creative 有创造力的 8. -en 表示「由……制成的」 wood(木) wooden 木制的 wool(羊毛) woolen 羊毛的 9. -ly 表示「像……的、有……性质的」 词缀 注意:-ly 加在名词后构成形容词,表示「具有……品质的」 friend(朋友) friendly 友好的 love(爱) lovely 可爱的 day(天) daily 每日的 week(周) weekly 每周的 10. -ish 表示「有点……的、像……的」 self(自己) selfish 自私的 child(孩子) childish 幼稚的 fool(傻瓜) foolish 愚蠢的 11. -ic / -ical 表示「……的」 base(基础) basic 基本的 history(历史) historical 历史的 (三)副词后缀:把形容词变成副词 词缀 -ly 表示「……地」 quick(快的) quickly 快地 slow(慢的) slowly 慢地 careful(小心的) carefully 小心地 happy(高兴的) happily 高兴地 (四)动词后缀:把别的词变成动词 1. -en 表示「使变得……」 wide(宽的) widen 加宽 short(短的) shorten 缩短 strong(强壮的) strengthen 加强 length(长度) lengthen 加长 2. -ize / -ise 表示「使……化、使变成」 real(真实的) realize 意识到 organ(组织) organize 组织 词缀 3. -fy 表示「使……」 simple(简单的) simplify 简化 beauty(美) beautify 美化 (五)数词后缀 1. -teen 表示「十几」 three thirteen 十三 five fifteen 十五 2. -ty 表示「几十」 two twenty 二十 four forty 四十(注意不是 fourty) 3. -th 表示「第几」 four fourth 第四 six sixth 第六 Exercise. 1.

Then complete the table. Friday, 20 November In the past, I always felt stressed when I had to give a speech. I used to spend lots of time trying to memorize my speech, but I still forgot some parts. Last week, I decided to find out what the right way is to memorize a speech. I looked online and asked friends, and I found many useful methods. I learnt how to create a speech outline. Instead of trying to remember every word of my speech, I remembered the key words first. Then I formed images of these key words in my mind, and linked them in order. Another method is to divide the speech into short sections. I practised the first section until I could fully recall it. Then I moved on to the next. This helped me to find out which parts of the speech I needed to work on the most. Finally, a friend told me that I should have confidence in myself. Nobody knows my speech except me. If I do forget some words, I shouldn't panic. Just remember the key words and continue! I followed all these great methods and my speech today was a great success!

In my opinion, we still need to memorize important knowledge. The Internet cannot work all the time. If we depend too much on the Internet, we may become lazy. Basic memorization helps us understand new things better. When we keep knowledge in our mind, we can use it quickly without checking the Internet. I think we need a balance. We should memorize basic and useful knowledge, such as new words and key rules. But we don't have to remember every little detail. We can look up those less-important facts online. Memorization builds our brain, while the Internet helps us save time. We need both. I don't think we need to memorize many things. We can easily get all kinds of information online. Whenever we need facts or numbers, we can just search for them in seconds. Memorizing takes a lot of time. We should spend more time learning how to think creatively instead. Form two groups based on different opinions. Add at least three reasons to support your opinion. Have a debate on the question, Each student takes turns to speak. 05 Reflecting Can you talk about memories that are important to you? Can you use object clauses to express your opinions?
