Unit 1 课时6 Section B 2a-2c（大单元教学课件）英语新教材人教版九年级上册

该初中英语课件围绕“生态与乡村”主题，聚焦复合词构词特点、重点词汇及塞罕坝治理故事，通过“Let's Guess”复合词示例导入，经2a练习、2b句子填空到2c语篇复述，搭建从词到句到篇的学习支架。 其亮点是以塞罕坝“绿色奇迹”为语境，融合语言能力与文化意识培养，如视频问答理解故事，语篇填空运用词汇，对比今昔变化提升思维品质。构词法分类教学和分层作业助力学习能力发展，总结短语列表便于梳理，让学生提升语言运用与环保意识，为教师提供素养导向教学路径。

英语的常见构词分为合成词、派生词、转化词。其中合成词顾名思义就是用两个或两个以上的词组合起来的，具有与组成部分意义完全不同的新词，称作为合成词。合成词又称为复合词。常见的比如C表示海洋，food表示食物，那合在一起c food就是海里可以吃的食物，就是老师超爱的海鲜了。还有foot表示脚，ball表示球，加在一起你们就懂了。Football就是足球，快看，足球被踢飞了。英语中真的有这种学一词会多慈的好诗吗？当然有的话不多说，咱们继续剖析剖析合成词。暑假开学的前一天，王美丽在家疯狂的赶着老师布置的功课，家是home，功课是work，在家做的功课，家庭作业就是home work。这时候老妈给她送来了一杯水，说女儿放假还要赶作业，真的是太辛苦了，问她还要不要吃瓜瓜什么大瓜，我可是吃瓜小能手呢。老妈哈哈大笑，说是甜瓜melon，但water和melon放在一起，就能联想到西瓜watermelon。说完了王美丽，再来说说树下乘凉的弟弟王大强。突然，远方飞来了一个纸飞机，纸是paper，打开一看，上面有各种各样的新闻news。写满新闻的纸是啥？报纸、newspaper. 突然，上课铃声响了，大强回到教室，发现老师已经在上课了。上课是close，这个房间是room，那用于上课的房间就是教室classroom。那同一个道理，黑板是blackboard，黑色的是black，就是board的等等。你以为这就完了？还有话说北方的冬天那是有看不完的。雪雪是snow。这个时候跑过来一个小胖，小胖当然是人了，我们就用man，那他在干嘛呢？当然是堆雪人，看这个用雪堆成的人就是雪人。我们用还有电视剧里总说的小心火烛。森林一不小心着火了，fire火跑过来一个人，man救火的人，你懂的，就是fireman、消防员。一不小心说了这么多词，合成词大家都学会了吗？简单粗暴的理解就是由两个或两个以上的词构成的新词就叫做合成词。英语词汇千千万，掌握好合成词，分分合合。我不再是我，你不是你，单词再也不用死记硬背。今天的英语小课堂就到这儿了，下期不见不散拜。 Unit 1 The Changing World Section B 2a-2c Learning Objectives 通过本节课的学习，学生能够： 1.识别并梳理生态、乡村主题下常见复合词，理解复合词构词特点，结合语境读懂词义，能够在句子练习中正确运用复合词（学习理解）。 2.依托语篇掌握本课重点词形变化，提取塞罕坝治理故事关键信息，借助提示，使用正确词形完整复述塞罕坝生态治理故事，对比环境的今昔变化（应用实践）。 3.体会劳动付出和政府扶持对荒漠化治理的重要意义；可以结合自身认知简单谈论家乡生态或乡村发展，树立爱护环境、建设家乡的意识（迁移创新）。 感 谢 观 看 01 New Words narrow /ˈnærəʊ/ adj.狭窄的 villager /ˈvɪlɪdʒə(r)/ n.村民 the Olympics/əˈlɪmpɪks/ (=the Olympic Games) 奥林匹克运动会 lead /liːd/ v.带领 n.领先地位 man-made /ˌmæn ˈmeɪd/ adj.人造的;非天然的 miracle/ˈmɪrəkl/ n.奇迹 (led/led,led) village n. 乡村 man + made =man-made 反：wide n.宽阔的 02 Word Building egg +plant pineapple  firefly pine +apple  Let's Guess eggplant fire +fly Compound words man-made  man +made  Let's learn.
