Unit 4 Digital Life Understanding ideas Grammar课件 -2025-2026学年外研版八年级英语上册

该初中英语课件聚焦动词不定式作宾语补足语，围绕“Digital Life”主题展开。课堂导入通过视频观看（关注不定式）、生活化对话（如智能手机支付场景）激发兴趣，先复习不定式作宾语结构，再对比新授“动词+宾语+不定式”结构，用“主谓关系”黄金判断法则搭建学习支架，帮助学生清晰区分宾语与宾补。 其亮点在于融合语言能力与思维品质培养，通过语境化任务（如主题短文填空“Last month, my teacher asked us to research digital technologies”）让学生在真实情境中运用语法，设置“使役动词省略to”等思考问题提升分析能力。采用多元评价与分层作业（必做造句、选做家庭规则短文），学生能夯实语法应用能力，教师可借助清晰教学流程高效推进课堂。

Lead-in Pre-learning While-learning Post-learning Diversify assessment Page 130 Lead-in Pre-learning While-learning Post-learning Diversify assessment Review:动词不定式作宾语 定义：不定式直接跟在及物动词后，作动词的“动作对象”（宾语）。 结构：主语 + 谓语（及物动词） + to do（宾语） eg: He plans to ride a shared bike to school. They need to download the learning app. Lead-in Pre-learning While-learning Post-learning Diversify assessment 什么是“宾语补足语” 已知结构（不定式作宾语） 新结构 I decide to explore digital life. The teacher asks us to explore digital life. We hope to use digital payment. The shopkeeper allows us to use digital payment. 1. 新句子中，“us”是什么成分？ 2.“to explore/to use”在说明谁的动作？ 定义：补充说明“宾语”的动作、状态或身份的成分，让句子意思更完整。 核心逻辑：宾补是“宾语”发出的动作（如上述句子中，“to explore”是“us”的动作，“to use”是“us”的动作）。 Lead-in Pre-learning While-learning Post-learning Diversify assessment 宾语补足语： 放在宾语之后，补充说明宾语 “做什么” 或 “怎么样” ，使句意完整。 信息断裂 I want you. 你想让我做什么？句意不完整。 信息自洽 I want you to be happy. “to be happy”补充说明“你”要怎么样，句子意义完整。 什么是“宾语补足语” For example: Lead-in Pre-learning While-learning Post-learning Diversify assessment 宾语？ 宾补？ 宾语: her roommate 宾补: to turn down the music 宾语: the panda 宾补: to be its symbol 在“动词 + 宾语 + to do”结构中，动词不定式 to do 充当宾语补足语，对宾语进行补充说明。 Lead-in Pre-learning While-learning Post-learning Diversify assessment 宾补结构黄金公式 主语 (S) + 谓语 (V) + 宾语 (O) + 宾语补足语 (OC) I（主语） asked（谓语） the shopkeeper（宾语） to show the QR code（宾补）.

(看见他正在过马路) see sb do sth hear sb do sth feel sb do sth watch sb do sth notice sb do sth see sb doing sth hear sb doing sth feel sb doing sth watch sb doing sth notice sb doing sth 什么动词省略to？？ 感官动词 Lead-in Pre-learning While-learning Post-learning Diversify assessment Page 131 help help双规：to可省可留 Help 后接 to do，正式文体中保留 to，更显礼貌。 Help 后接 do，口语或非正式文体中省略 to，更简洁。 核心规则：help 后的 to 可省可不省，意思不变。 eg. Can you help me (to) carry this box? Lead-in Pre-learning While-learning Post-learning Diversify assessment 区分：宾语 (O) vs 宾补 (OC) A: I hope to see you.
