语法点
本单元语法主要关于物主代词和频度副词等。
物主代词:
一)概念
物主代词 (Possessive Pronouns) ,用于表示所属关系,分为形容词性物主代词和名词性物主代词两类,功能不同:
类型 作用 示例
形容词性物主代词 修饰名词(必须+名词) This is my book.这是我的书
名词性物主代词 代替名词(独立使用) The book is mine. 这书是我的
二)物主代词分类表
人称 形容词性物主代词 名词性物主代词
第一人称单数 my(我的) mine(我的)
第二人称单数 your(你的) yours(你的)
第三人称单数 his/her/its(他的/她的/它的) his/hers(他的/她的)
第一人称复数 our(我们的) ours(我们的)
第二人称复数 your(你们的) yours(你们的)
第三人称复数 their(他们的) theirs(他们的)
注意:
its(它的)没有名词性物主代词形式,需用"its + 名词"结构。
The dog wagged its tail. (√)
The tail is its. (× 错误用法)
三)形容词性物主代词用法
规则:必须后接名词,不可单独使用。
功能:作定语,修饰名词。
例句:
1. Her dress is beautiful. (她的裙子很漂亮。)
2. Students should finish their homework. (学生应完成他们的作业。)
3. The cat is licking its paws. (猫在舔它的爪子。)
易错点:
This pen is my. (×)→ 形容词性不能独立使用
This is my pen. 或 The pen is mine. (√)
四)名词性物主代词用法
规则:独立使用,相当于"形容词性物主代词 + 名词"。
- Is this your bag No, it's hers(=her bag). (这是你的包吗?不,是她的。)
可以作主语/宾语/表语:
- Ours is the red car. (我们的车是红色的。→ 主语)
- I broke mine. (我弄坏了我的。→ 宾语)
- These keys are theirs. (这些钥匙是他们的。→ 表语)
对比下:
- This is my bike. (形容词性 + 名词)
- This bike is mine. (名词性独立使用)
五)of所有格(拓展)
Of所有格经常出现,主要表示无生命体和抽象概念时使用。
结构:名词A + of + 名词B(表示"B的A")
主要类型 示例 说明
无生命所属 the roof of the house 房子顶部 建筑部件
抽象概念 the cost of living 生活成本 抽象名词修饰
六)特殊用法与注意事项
1. 双重所有格:of + 名词性物主代词
- a friend of mine (我的一个朋友)
- 比较:my friend(特指)/ a friend of mine(泛指)
强调专属:of one's own
He wants a room of his own.(他想要个属于自己的房间)
2. 固定搭配:
- Do your best! (尽力而为!)
- Mind your own business! (管好你自己的事!)
3. its vs. it's:
- its:物主代词(它的)
- The dog wagged its tail.
- it's:it is 或 it has 的缩写
- It's raining. (= It is)
七)易错点辨析
1. 混淆形容词性与名词性:
This is mine book. (×)
This is my book. 或 This book is mine. (√)
2. 误用名词性物主代词:
The pen is your. (×)
The pen is yours. (√)
3. its 与 it's 混用:
The bird built it's nest. (×)
The bird built its nest. (√)
八)练一下
1. 用适当物主代词填空:
- She lost _____ (her/hers) keys. → her
- Is this calculator _____ (your/yours) → yours
- That idea of _____ (your/yours) is great! → yours
2. 改写句子:
- This is my umbrella. → This umbrella is _____ . (mine)
- Their house is bigger than our house. → Their house is bigger than _____ . (ours)
总结下:
语法点 核心规则 经典示例
形容词性物主代词 必须+名词 Our team won.
名词性物主代词 独立使用 The prize is theirs.
of所有格 无生命体/抽象概念 the end of the movie
双重所有格 of + 名词性物主代词 a student of hers
频度副词:
频度副词 (Adverbs of Frequency) 全面语法讲解
一)概念
频度副词用于表示动作发生的频率,回答"How often "的问题。它们在句中主要修饰动词,说明动作的规律性或重复性。
