Unit1 Understanding ideas-Grammar 课件2025-2026学年外研版英语八年级下册

该初中英语课件核心围绕被动语态（一般现在时和一般将来时）展开，从Robert工作回忆的对话导入，通过主动与被动句对比引出语法规则，再经例句分析、阅读找句、填空练习等搭建从理解到应用的学习支架。 其亮点在于融合语言能力与思维品质培养，通过学生会海报填写、职业挑战与乐趣讨论等任务型活动，让学生在真实情境中运用被动语态。采用例句对比、思维导图总结等方法，提升学生语言表达和逻辑分析能力，也为教师提供系统教学流程和多样化互动素材。

U1Career Talks Understanding ideas——Grammar 1 Think and answer. What will Robert keep in his memory? He will keep all my days up high in the air in his memory. All his days up high in the air will be kept in his memory. I will keep all my days up high in the air in my memory. All my days up high in the air will be kept in my memory. 动作的执行者 动作的承受者 主动语态 被动语态 Read the sentences and summarise the grammar rules. 主语（动作承受者）助动词be + 动词的过去分词 主动语态：主语（动作执行者） + 谓语 + 宾语 这两个句子表达的重点有所不同。 第2个句子侧重动作的执行者，强调某人做了什么。 第1组句子侧重动作的承受者，强调某事/事物如何。 因此当我们要突出某个动作的执行者时，应使用主动语态(第一组句子)来表达而要强调动作的承受者时，就要使用被动语态(第二组句子)来表达。 Now find one more sentence with these structures in the reading  passage. 助动词be + 动词的过去分词 4 Make a summary. 被动语态（Passive） The past 30 years were filled with both challenges and joys. All my days up high in the air will be kept in my memory. I’m reminded of some other friends I met through the glass. Window cleaning is not always considered a good job, but I’ll never regret it. 强调动作对象：句子主语是动作的承受者。 执行者可省略：当执行者未知、不重要或无需说明时，常省略“by + 执行者”。 被动语态是语法中的一种语态形式，用于强调动作的承受者（接受动作的人或事物），而非动作的执行者。它的核心是将句子的焦点从“谁做了某事”转移到“什么事被做了”。 Make a summary. 被动语态（Passive） I’m reminded of some other friends I met through the glass. Window cleaning is not always considered a good job, but I’ll never regret it. 一般现在时被动语态的各类句式总结如下: (1)肯定句:主语+am/is/are+动词过去分词(+by+动作执行者) (2)否定句:主语+am/is/are+not+动词过去分词(+by+动作执行者) (3)一般疑问句:Am/ls/Are+主语+动词过去分词(+by+动作执行者) (4)特殊疑问句:特殊疑问词+am/is/are+主语+动词过去分词(+by+动作执行者) 常见时间标志：频率副词（如：always、often、never）和every day等。 一般现在时： 主语+am/is/are+done (+by+动作执行者) Fill in the blanks. 1.
