Unit 3 单元核心语法精讲精练（专项训练）-2026-2027学年人教PEP版英语五年级上册

新人教版英语五年级上册单元核心语法精讲精练 Unit 3 Work and play 第一部分 核心语法梳理 本单元围绕“Work and play”（学习与娱乐）主题展开，核心语法包括以下三个方面： 语法一：一般现在时第三人称单数（动词三单变化） 基本用法：一般现在时表示经常发生的动作或存在的状态。当主语是第三人称单数（he, she, it, 单数人名，如Binbin, Chen Jie等）时，谓语动词要用第三人称单数形式。 动词三单变化规则： （1）一般情况下直接加-s：play→plays, like→likes, work→works, visit→visits （2）以s, x, ch, sh, o结尾的动词加-es：teach→teaches, wash→washes, go→goes, do→does （3）以“辅音字母 + y”结尾的动词，变y为i再加-es：study→studies, try→tries, fly→flies （4）特殊变化：have → has 例句： - Binbin goes to the Robot Club on Wednesdays after school. - Chen Jie does her homework on Saturday mornings. - She tidies her room on Saturday afternoons. - He has music class on Wednesday and Thursday mornings. 语法二：频度副词的用法（usually / often / sometimes） 基本用法：频度副词用来表示动作发生的频率，按频率从高到低排序为： -usually（通常）＞ often（经常）＞ sometimes（有时） 句中位置：频度副词通常放在实义动词之前，be动词/助动词/情态动词之后。 例句： - I usually have pipa lessons on Sundays. - I often play football at the weekend. - Sometimes I play Chinese chess with my father. - She often washes her clothes on Sunday afternoons. 易错提醒：频度副词不能放在动词后面。 ❌ I play usually football. → ✅ I usually play football. 语法三：星期名词与介词 on 的搭配 基本用法： -星期名词（Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday）均为专有名词，首字母必须大写。 - 表示“在星期几”用介词on：on Monday / on Mondays。 -on Mondays（带-s）表示“每逢周一”，强调习惯性活动；on Monday表示“在某个周一”，指具体某一天。 核心句型： - What do you have on Wednesdays? 你星期三有什么课？ — I have Chinese, maths, music and PE. - What do you usually do at the weekend? 你周末通常做什么？ —I often play football. Sometimes I play Chinese chess with my father. - Does Chen Jie do her homework on Saturday evenings? 陈杰星期六晚上做作业吗？ — No, she doesn’t. She does her homework on Saturday mornings. 第二部分 对应练习 练习一：用所给动词的适当形式填空。（10分） 1. Binbin __________ (go) to the Robot Club on Wednesdays. 2.
