Unit3 My school 名词所有格 & 双重所有格
语法总结
1. 名词所有格:
单数名词:加’s(如:Tom’s book)。
复数名词以s结尾:加’(如:students’ desks)。
无生命物体:多用of结构(如:the color of the car)。
2. 双重所有格:
结构为“of + 名词所有格”,强调所属关系中的一部分(如:a friend of my father’s)。
不可省略所有格符号(如:a friend of my father’s ≠ a friend of my father)。
3. 常见错误:
混淆复数所有格的’s和’(如:children’s vs. students’)。
双重所有格中未正确使用所有格形式(如:a friend of my father → a friend of my father’s)。
比较对象的所有格缺失(如:the dog’s tail vs. the dog)。

名词所有格 & 形容词性物主代词
语法总结与提升
1. 形容词性物主代词 vs. 名词所有格:
形容词性物主代词(my/your/his...)必须后接名词:
This is her book.
名词所有格(Tom’s/students’)直接表示所属关系:
This is Tom’s book.
2. 混合使用规则:
当句子同时涉及“所属人”和“所属物”时,需灵活搭配:
A friend of my sister’s gave me her old bike.(双重所有格 + 形容词性物主代词)
3. 高频易错点:
混淆名词性物主代词(mine/yours)与形容词性物主代词(my/your);
双重所有格中遗漏所有格符号(如:a friend of my father → a friend of my father’s);
比较句中所有格缺失(如:the dog’s tail vs. the dog)。
