Unit 6 Beyond Earth 第3课时 Grammar Focus (4a~4c)(语法课)
基本信息 课题:Unit 6 Beyond Earth — Grammar Focus (4a~4c) 课型:语法课|课时:1课时(45分钟)|授课年级:九年级上册
核心素养目标 语言能力 观察并归纳一般将来时被动语态的构成与用法;掌握 require、cancel、publish、melt 等本课词汇,能用被动语态描述太空探索中的将来事件。 学习能力 通过观察例句、归纳规则、替换操练和语篇填空掌握语法结构,在小组互查中巩固。 思维品质 对比主动句与被动句的表达侧重,体会被动语态在客观描述科技事件中的作用。 文化意识 在系外行星、未来太空探索等话题中感受科技进步,继续保持对宇宙的好奇与探索热情。
教学重难点 教学重点 ①观察 4a 例句,归纳一般将来时被动语态“主语 + will be + 过去分词”的构成;②完成 4b 主动改被动、4c 语篇填空;③掌握 require、melt 等词汇及 require sb. to do 用法。 教学难点 ①主动句改被动句时主谓与时态保持一致;②在语篇中正确选用被动语态。
语言点
Language Points 1. This project will require students to do research on space exploration. 这个项目将要求学生进行太空探索方面的研究。(P55) require v. 需要;要求;requirement n. 所需的东西。 用法:require sth. 需要某物;require sb. to do sth. 需要/要求某人做某事;be required to do sth. 被要求做某事;require + that 从句 需要/要求……。 例句:The teacher required Tom to keep quiet. 老师要求汤姆保持安静。
教学环节 师生活动 活动观层次 评价要点
Step 1
Review & Lead-in ①话题导入:齐读上节课提到的 Space Dreams 小诗,回顾与太空有关的词汇。 ②师生互动:教师出示小诗(Far stars are watched through silver glass, / New rockets are launched to pass. / Data is sent back from dark space, / Mysteries are solved at a steady pace. / New bases will be built on the moon, / Our wild space dreams will be soon immune. / Great achievements have been made by us, / The unknown sky will never stop us.),学生齐读并圈出其中的动词,自然进入本课语法学习。 学习理解
感知与注意 话题导入与旧知激活
设计意图 用一首太空小诗回顾旧词,顺势引出今天要学的被动语态。
Step 2
Topic Vocabulary:
Present & Practice ①词汇(音形义):require v. 需要;要求 rocket n. 火箭 cancel v. 取消;终止 publish v. 刊登;出版 exoplanet n. 系外行星 solar adj. 太阳的;太阳能的;melt v.(使)融化;逐渐消失 pipe n. 管道;管子;烟斗 tunnel n. 隧道;地下通道 tourism n. 旅游业 gain v. 获得;取得 ②跟读与感知:教师带读音标,学生在例句中体会音形义与搭配。 ③检测:同桌互考认读与拼写,教师用闪卡或听写快速检查,及时纠正发音。 学习理解
感知与注意 新词认读与拼写
设计意图 先读准本课新词,为做语法练习和阅读系外行星短文扫清障碍。
Step 3
Observe Examples:
Discover Rules ①任务:Read the sentences and underline the verbs in the passive voice. Pay attention to how they are used in the simple future tense. ②素材:①New technology will soon be developed. ②Exploration of the planet Mars will be continued. ③International research stations will be built on the moon and Mars. ④Will life be found on another planet ⑤Will you be visited by other astronauts (均为一般将来时被动语态) ③教师出示五个例句,学生找出其中的被动语态动词,观察它们在一般将来时中的形式,自己归纳出 will be + 过去分词。 应用实践
观察与发现 语法观察与操练
设计意图 让学生先自己观察例句、发现被动语态的构成,而不是直接讲规则。
Step 4
Practice:
Active to Passive ①任务:Change these sentences from the active voice to the passive voice. ②素材:将下列主动语态改为被动语态: 1. This project will require students to do research on space exploration. → Students will be required to do research on space exploration (by this project). 2. Scientists will position more satellites in space. → More satellites will be positioned in space (by scientists). 3. Because of the bad weather, they will cancel the trip to the space museum. → The trip to the space museum will be cancelled (by them) because of the bad weather. 4. The magazine will publish an article about future space travel next month. → An article about future space travel will be published (by the magazine) next month. 5. Will the space centre launch a new rocket next month → Will a new rocket be launched (by the space centre) next month ③学生独立把五个主动句改成被动句,教师提醒 by 短语可省略;完成后同桌互查,教师点评易错处。 应用实践
观察与发现 语法观察与操练
设计意图 通过主动改被动的替换操练,巩固一般将来时被动语态的结构。
Step 5
Text:
Apply Passive Voice ①任务:Complete the passage with the correct forms of the words in brackets. Whatare exoplanets What are your views on finding life on another planet ②素材:Complete the passage with the correct forms of the words in brackets. What are exoplanets What are your views on finding life on another planet For a long time, scientists have known that the universe ________ (fill) with stars.(is filled) In more recent times, however, thousands of “exoplanets” have also been ________ (discover).(discovered) These are planets that ________ (move) around stars—just like in our own solar system.(move) So far, more than 5,000 exoplanets ________ (know) to us, and as technology improves, many more ________ (find).(have been known;will be found) Some exoplanets are similar to Earth. They are of a similar size and temperature, and they might have water. Scientists are excited about this. It ________ (think) that if there is water, there might also be alien life!(is thought) ③学生通读关于系外行星的短文,用括号内动词的正确形式填空,注意该用主动还是被动、用什么时态;完成后教师核对。 应用实践
观察与发现 语法观察与操练
设计意图 把刚学的被动语态放进真实语篇中运用,体会它在客观描述中的作用。
Step 6
Consolidation:
Diagnose & Fill Gaps ①独立完成:完成课内 Exercise——按要求完成句子: 1. According to the plan, we will plant more trees this spring.(改为被动语态)→ According to the plan, more trees will ________ ________ this spring.(答案:be planted) 2. Volunteers will collect the waste in the park this weekend.(改为被动语态)→ The waste in the park ________ ________ ________ by volunteers this weekend.(答案:will be collected) 3. 据说他的新书下个月将出版。(翻译句子)→ It is said that his new book ________ ________ ________ next month.(答案:will be published) ②互查订正:同桌互查、红笔订正,把拿不准的题标记出来。 ③精讲:教师统计错误集中的题目当堂讲评,学生立即订正。 应用实践
内化与运用 练习正确率
设计意图 通过改写和翻译当堂检测一般将来时被动语态,及时查漏补缺。
作业设计(分层) 基础 熟记 require、cancel、publish、melt 等词汇及 require sb. to do;朗读并背诵 4a 例句。 拓展 用一般将来时被动语态写一段不少于 80 词的短文,描述人类未来在太空会做哪些事。 探究 查阅一颗系外行星的资料,下节课用一两句英语向同学介绍。
板书设计 Unit 6 Beyond Earth — Grammar Focus (4a~4c) 话题词汇:require, rocket, cancel, publish, exoplanet, solar, melt, pipe, tunnel, tourism, gain 一般将来时被动语态:肯定 主语 + will be + 过去分词;否定 主语 + won’t be + 过去分词;疑问 Will + 主语 + be + 过去分词? 活动链:4a 观察例句 → 4b 主动改被动 → 4c 语篇填空 主题:用被动语态客观描述太空探索
教学评价与反思 1. 评价方式(教-学-评一体化): 语言能力——一般将来时被动语态的改写是否正确,词汇运用是否准确 学习能力——能否自己观察例句、归纳规则并完成操练 思维品质——能否说清主动句与被动句的表达侧重 文化意识——对系外行星等话题是否有兴趣 2. 课后反思:①语法规则是否由学生自己归纳;②主动改被动的易错点是否当堂讲评;③语篇填空是否先通读再做;④作业是否分层、便于检查。
