说明:涵盖七上核心语法点,含规则梳理、例句及专项练习,便于碎片化巩固!
一、名词:单复数变化(重点)
核心规则:1. 一般直接加-s(book→books);2. 以s/x/ch/sh结尾加-es(box→boxes,watch→watches);3. 以“辅音+y”结尾变y为i加-es(family→families);4. 不规则变化(man→men,child→children,sheep→sheep);5. 不可数名词无复数(water, rice, bread,前用some/much修饰)。
专项练习:写出下列名词复数形式 1. pen____ 2. bus____ 3. baby____ 4. foot____ 5. fish____
二、代词:人称/物主代词(基础)
人称 | 主格(作主语) | 宾格(作宾语) | 形容词性物主代词(+名词) | 名词性物主代词(代名词) |
|---|---|---|---|---|
我 | I | me | my | mine |
他 | he | him | his | his |

专项练习:用合适代词填空 1. ____(我)am a student. 2. This is ____(他的)pen. 3. The book is ____(我的). 4. Let ____(我们)go to school.
三、动词:be动词/实义动词(核心)
1. be动词用法:我用am,你用are,is连着他/她/它;单数名词用is,复数名词全用are。(否定:am not/isn't/aren't;疑问:提前be动词)
例句:He is a teacher. → Is he a teacher? → He isn't a teacher.
2. 实义动词(如like, play):主语是第三人称单数(he/she/it/单名)时,动词加-s/es(like→likes,play→plays);其他人称用原形。
专项练习:用be动词或实义动词适当形式填空 1. She ____(be)my sister. 2. He ____(like)apples. 3. They ____(play)football every day. 4. ____(be)you a student?
