寒假预习:专题06 Unit 3 Everyone’s got talent!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)。
3. 课本原句例句:
— What are you doing? (你正在做什么?)
→ I'm dancing. (我正在跳舞。)(dance → dancing,直接加-ing)
— What are you looking at? (你正在看什么?)
→ I'm looking at their clothes. (我正在看她们的衣服。)(look → looking)
4. 易错提醒:be动词要和主语一致(I用am,you用are,he/she/it/三单名词用is),动词-ing形式拼写无误。
核心语法点2:be good at 的用法(本单元重点)—— 描述擅长的事情、天赋
1. 语法含义:表示“擅长……”,专门用于描述某人的天赋、特长,后面接动作或事情。
2. 关键规则:be good at + 动词-ing形式 / 名词(不能直接接动词原形)。
3. 课本原句例句:
— I'm good at dancing. (我擅长跳舞。)(dance → dancing,去e加-ing)
— She is good at doing magic. (她擅长变魔术。)(do → doing)
— He is good at playing the piano. (他擅长弹钢琴。)(play → playing)
核心语法点3:情态动词can 的用法(深化应用)—— 表达请求、能力
1. 语法含义:本单元中,主要用于表达“请求帮助、请求教某事”,也可表示“能、会”(能力)。
2. 关键规则:can 后面永远接动词原形;一般疑问句直接把can提前,肯定回答用“Yes, ... can.”,否定回答用“No, ... can't.”。
3. 课本原句例句:
— Can you teach me to dance? (你能教我跳舞吗?)
→ Of course, I can. (当然可以。)
— He can do magic with a hat. (他能用帽子变魔术。)
核心语法点4:一般现在时(深化)—— 描述能力、习惯性表现
1. 语法含义:本单元中,用于描述某人的长期能力(如跳舞好、擅长某事),或习惯性的表现。
2. 关键规则:主语是第三人称单数时,动词加-s/-es;主语是复数/第一人称时,动词用原形。
3. 课本原句例句:
— She dances well. (她跳舞跳得好。)(主语she是三单,dance → dances)
— Lingling wins the show. (玲玲赢得比赛。)(主语Lingling是三单,win → wins)
