Unit1高分重点练 语法专题精练 2026-2027学年外研版英语七年级上册

外研版（2026）七年级上册 Unit 1 A new start Unit 1 A new start 高分重点练·语法专题精练（人称代词与物主代词） 姓名：____________　　班级：____________　　得分：____________ 【语法精讲】 要点一　基础规则（主格作主语、宾格作宾语） 人称代词主格（I / you / he / she / it / we / they）在句中作主语，放在动词前；宾格（me / you / him / her / it / us / them）在句中作动词或介词的宾语，放在动词或介词后。 例：I am a new student.　　　　　The teacher helps me with English. 要点二　进阶规则（形容词性 vs 名词性物主代词） 形容词性物主代词（my / your / his / her / its / our / their）后面必须接名词；名词性物主代词（mine / yours / his / hers / its / ours / theirs）本身相当于「形容词性物主代词＋名词」，后面不再接名词。 例：This is my book. = This book is mine.　　　　That is her pen. = That pen is hers. 要点三　特殊用法 ① it 可指代事物、动物、天气、时间等；② 复数 they / them / their / theirs 配对使用，复数名词一律用 their，不用 his/her。 例：Our school is big. It is beautiful.　　　　These are their books. = These books are theirs. 易错点 × I is a student.（be 动词与主格不搭配）　√ I am a student. × This pen is my.（误把形容词性物主代词当名词性用）　√ This pen is mine. × The teacher helps I.（动词后应用宾格）　√ The teacher helps me.
