名词性物主代词：独立使用，相当于“形容词性物主代词+名词”（The book is mine.=The
book is my book.）。
特殊注意：its（它的）无名词性/形容词性区分，it’s是it is的缩写（It’s a dog. Its
name is Coco.）。

学习总结
核心语法点速记
1.频率副词：
频率排序（从高到低）：always > usually > often > sometimes > seldom > never。
位置规则：be动词后、实义动词前，sometimes可放句首/句中/句尾。
提问用How often（多久一次）。
2.物主代词：
形容词性+名词（my book），名词性=形容词性+名词（mine=my book）。
易错区分：its（它的）vs it’s（它是），your（你的）vs you’re（你是）。
学科网（北京）股份有限公司易错点警示
频率副词误用：sometimes（有时）≠ some times（几次），seldom无副词形式seldomly。
物主代词混用：形容词性物主代词后必须有名词，名词性物主代词独立使用（如不能说mine
book，应为my book或mine）。
