人教PEP五年级上册英语核心语法精讲精练
Unit 3 Work and play
单元主题:工作与课余生活(日常作息、职业行为、课余活动)
核心语法清单(本单元必考4大语法)
1.一般现在时(主语三单vs非三单)动词变化规则
2.一般现在时一般疑问句(Do/Does 提问)及答语
3.频度副词用法(always/usually/often/sometimes/never 位置+用法)
4.时间介词 on 的用法(星期/具体日期前用on)
语法一:一般现在时——动词第三人称单数变化(单元重中之重)
【语法精讲】
一般现在时表示经常性、习惯性的动作或常态,本单元用于描述:日常工作、周末活动、课余爱好。
1.什么时候用三单?
主语为第三人称单数:he / she / it / 单个人名(Tom, my mother)/ 单数名词
2. 动词三单变化规则
①一般动词:直接加-s 例:work→works, play→plays, like→likes
②以 s/x/ch/sh/o 结尾:加-es 例:watch→watches, go→goes, do→does
③辅音字母+y 结尾:变 y 为 i,加 -es 例:study→studies
④ 特殊不规则变化:have → has(单元最高频考点)
3.非三单主语(I/you/we/they/复数人名):动词用原形
【易错点拨】
1.Does 后面、don’t/doesn’t 后面,动词必须还原原形,不能加s/es;
2.只有一般现在时、肯定句、三单主语动词才变形,否定、疑问大多还原。
【语法一专项练习】(15分)
一、写出下列动词的第三人称单数形式(每空1分,8分)
1.play ________ 2.work ________ 3.watch ________
4.do ________ 5.go ________ 6. have ________
7.study ________ 8.take ________
二、用动词正确形式填空(每空1分,7分)
1. My father ________ (work) in a hospital.
2. Tom often ________ (play) football after school.
3. They ________ (have) PE class on Monday.
4. She ________ (have) lunch at school.
5. He ________ (do) his homework every evening.
6. We ________ (not watch) TV on school days.
7. Amy ________ (not go) to the park on weekends.
语法二:一般现在时一般疑问句(Do / Does 提问)
【语法精讲】
1. 句型结构
非三单:Do + 主语 + 动词原形…?
三单:Does + 主语 + 动词原形…?
2. 标准答语
Do 提问:Yes, 主语 do. / No, 主语 don’t.
Does 提问:Yes, 主语 does. / No, 主语 doesn’t.
核心口诀:Does出现,动词还原;问答一致,单复对应
【易错点拨】
很多同学易错:问句用Does,回答误用don’t;或者问句里动词依然加s。
【语法二专项练习】(15分)

2. I often play basketball.(改为一般疑问句并否定回答)

语法三:频度副词用法(单元必考情景语法)
【语法精讲】
1. 频度副词梯度(频率从高到低)
always(总是100%)> usually(通常)> often(经常)> sometimes(有时)> never(从不0%)
2. 黄金位置口诀
实前系后,助后情后
✅ 实义动词之前:I often play football.
✅ be动词/情态动词/助动词之后:She is always happy. / Do you usually get up early?
【易错点拨】
sometimes 位置最灵活,可放句首、句中、句尾;never 本身含否定意义,不再加not。
