Unit 3 The Internet Discovering Useful Structures 导学案 -2026-2027学年高中英语人教版必修第二册

人教版必修2单元3　Discovering Useful Structures 现在完成时被动语态（Present Perfect Passive Voice） 人教版（2019）必修第二册　|　情境主线：变化中的武汉（Changes in Wuhan） 学习目标 1. 通过观察成对例句，归纳现在完成时被动语态的构成：have / has + been + done。 2. 能说出被动语态的使用场景：不知道或不必说出动作的执行者、强调动作的承受者。 3. 能在“武汉变化”这一话题中正确使用现在完成时被动语态，并完成一段小语段写作。 学习重难点 重点：现在完成时被动语态的构成（have / has been + done）及其基本用法。 难点：have / has 与主语保持一致；被动结构中 been 不遗漏；主动句转换为被动句时，主语与动词形式的调整。 学情分析 学生在初中和本单元前几课时已接触过现在完成时的主动语态，以及一般现在时、一般过去时的被动语态；但把“完成时”和“被动”合在一起使用时，常出现 been 漏写、have / has 与主语不一致的问题。学生对武汉本地话题熟悉，用城市变化的情境容易调动开口与写作的兴趣。 Part Ⅰ　Observation and Discovery Activity 1　Read and compare.

Part Ⅳ　Production: Write a "Wuhan Calling Card" Activity 1　Follow the example poem and write 4-6 sentences about the changes in Wuhan (or your hometown). Use at least 3 present perfect passive verbs. Example: Look at the way the riverbank has been rebuilt, Look at the way the cherry trees have been planted, Look at the way the old factory has been changed, Look at the way Wuhan has been renewed. My writing: 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 Activity 2　Check your work with the checklist below. [ ] I have used at least 3 present perfect passive verbs [ ] have / has agrees with the subject [ ] I have not missed "been" [ ] My writing is about changes in Wuhan or my hometown 参考答案 Reference Answers Part Ⅰ Activity 1：被动句 = have / has + been + done，动作的承受者作句子主语。 Activity 2：按空格顺序（表格行内从左到右、逐行往下）依次为 been；done；been；been；Have；Has；have / has；has。 Part Ⅱ Activity 1： 1. The Yellow Crane Tower has been repaired recently. 2. About 500,000 trees have been planted along the Yangtze River. 3. The old factory has been turned into a creative park. 4. A new riverside park has been opened this spring. 5. Many stories about the changes in Wuhan have been written. Activity 2：B 更自然。谈话的焦点是“图书馆已建成”这件事（承受者），执行者是谁无关紧要；当不知道、不必说出或不强调执行者时，用被动语态。 Part Ⅲ have been rebuilt；has been repaired；has been opened；have been planted；have been attracted；have been added；has been turned。 说明：every spring 通常是一般现在时的时间标志，此处用现在完成时被动（have been attracted）强调“到目前为止已经吸引了大量游客”这一已发生的结果及其对现在的影响，而非每一年的常规动作。 Part Ⅳ 开放性任务：能正确使用 3 个及以上现在完成时被动语态、内容扣题即可。 学科网（北京）股份有限公司 $
