寒假预习:专题08 Unit 4 Plant life语法讲义+知识演练2025-2026学年四年级下册英语(外研版) 核心语法点1:现在进行时—— 询问/描述正在进行的种植相关动作 1. 语法含义:表示此时此刻正在进行、发生的动作。 2. 关键规则:主语 + be动词(am/is/are)+ 动词-ing形式(动词原形加-ing);否定句在be动词后加not,一般疑问句将be动词提前。 3. 课本原句例句: — What are you doing? (你正在做什么?) — We're digging. (我们正在挖洞。) — Are your seeds growing? (你的种子在生长吗?) — Yes, they are. (是的,它们在生长。) — They're planting tomato seeds. (他们正在种西红柿种子。) 4. 易错提醒:be动词与主语一致(I用am,you用are,he/she/it/三单名词用is);dig→digging、plant→planting,动词-ing形式拼写无误。 核心语法点2:一般现在时—— 描述日常动作、植物生长规律或长期状态 1. 语法含义:表示经常性、习惯性的动作,或植物生长的规律、某人的长期状态(如爷爷经常在田里工作)。 2. 关键规则:主语是第三人称单数(he/she/it/单数名词)时,动词加-s/-es;主语是复数/第一人称(I/we/you/they)时,动词用原形。 3. 课本原句例句: — Grandpa often works in the fields. (爷爷经常在田里工作。)(Grandpa是三单,work→works) — The sunflower grows tall and strong. (向日葵长得又高又壮。)(sunflower是三单,grow→grows) — The seed grows into a small plant. (种子长成一棵小植物。)(seed是三单,grow→grows) 核心语法点3:情态动词will 的用法—— 描述将来会发生的动作或愿望 1. 语法含义:表示“将、会”,用于描述未来植物的生长变化,或某人的愿望、梦想(如爷爷的梦想)。 2. 关键规则:will 后面永远接动词原形;否定句在will后加not(缩写为won't),一般疑问句将will提前。 3. 课本原句例句: — He will grow tall rice plants. (他想种/将会种高大的水稻。)(grow用原形) — The seed will grow into a big tree. (这颗种子将会长成一棵大树。)(grow用原形) — I think his dreams will come true. (我认为他的梦想将会实现。)(come用原形) 核心语法点4:名词单复数—— 描述植物的组成部分 1. 语法含义:本单元重点考查植物部位相关名词的单复数变化,用于描述多棵植物或植物的多个部位。 2. 关键规则:大部分名词变复数加-s;以f/fe结尾的名词变复数,变f/fe为v再加-es(如leaf→leaves);不规则变化(如mouse→mice)。 3. 课本原句例句: —— Look at my roots. (看我的根。)(root→roots,加-s) —— My leaves are green. (我的叶子是绿色的。)(leaf→leaves,以f结尾,变f为v再加-es,规则变化) — I've got a mouse. (我有一只老鼠。) → They've got two mice. (他们有两只老鼠。)(mouse→mice) 核心语法点5:一般疑问句—— 询问植物生长情况或动作 1. 语法含义:本单元重点考查be动词(am/is/are)和助动词(do/does)引导的一般疑问句,用于询问种子生长、他人动作等。 2. 关键规则:be动词引导的疑问句,用be动词回答;do/does引导的疑问句,用do/does回答,动词用原形。 3. 课本原句例句: — Are your seeds growing? (你的种子在生长吗?) — Yes, they are. / No, they aren't. — Does Grandpa often work in the fields? (爷爷经常在田里工作吗? — Yes, he does. / No, he doesn't. 知识演练 一、语法填空 1. What are you doing?
