初中英语语法(名词篇)

初中英语语法(名词篇)
语法不用死记硬背,吃透这一套,搞定名词核心考点✨
一、名词
(一)名词的分类与数
1. 可数名词与不可数名词的基本区分
可数名词有单复数形式,可用 a/an 修饰,可用 many/few 修饰;
不可数名词没有复数形式,用 much/little 修饰,需借助量词表达数量。
这是名词学习的基础,也是语法填空、短文改错高频考点。
①I have a book and many pens.
②There is much water in the bottle.
③She gave me a piece of advice.
2. 可数名词复数的不规则变化
英语中有大量名词复数变化不规则,需逐个记忆。
✅以-f/fe结尾变-ves(如leaf→leaves)
✅以-o结尾部分加-es(如hero→heroes)
✅元音变化(如man→men)
✅单复数同形(如sheep→sheep)
①The children are playing in the garden.
②Three women doctors came to help.
③There are many deer in the forest.
3. 复合名词的复数形式
复合名词变复数时,通常在核心名词上加复数。若无核心名词,则在词尾加-s。
👉passer-by→passers-by(过路人),sister-in-law→sisters-in-law(嫂子)
👉grown-up→grown-ups(成年人),在词尾变化
①Two passers-by witnessed the accident.
②All the lookers-on were excited.
4. 集体名词的单复数用法
集体名词如family、team、class、audience等:
🔹强调整体时 → 作单数
🔹强调个体成员时 → 作复数
police、cattle等总是用作复数。主谓一致重要考点!
①My family is a large one.(整体)
②My family are all music lovers.(个体)
③The police are searching for the thief.
5. 不可数名词的具体化用法
某些不可数名词在特定语境中可转化为可数名词,表示“一种/一场/一份”。
👉a success(一个成功的人/事)、a beauty(一个美人)、a heavy rain(一场大雨)
①The party was a great success.
②What a surprise you gave us!
③She is a beauty in everyone’s eyes.
6. 常考不可数名词归纳
🔥必背不可数名词(不能直接加a/an)
advice、information、news、furniture、equipment、luggage、progress、weather、work(工作)、knowledge
①I need some information about the train schedule.
②The furniture in this room is very expensive.
③What fine weather we have today!
7. 名词作定语时的单复数规则
名词作定语修饰另一名词时,通常用单数形式,哪怕含义是复数。
👉apple trees(苹果树)、shoe shops(鞋店)
⚠️特殊:man/woman作定语,要和后面名词的数保持一致
①There are many apple trees in the orchard.
②Two women doctors are on duty today.
③I bought a pair of sports shoes yesterday.
8. 双重所有格的用法
双重所有格: of+名词’s  或  of+名词性物主代词 
含义:其中之一,常带有感情色彩
👉a friend of my father’s(我父亲的一个朋友)
👉that lovely dog of yours(你那条可爱的狗)
①He is a friend of my brother’s.
②That car of yours is really cool.
③I love this beautiful painting of Li’s.
9. 名词所有格的省略用法
名词所有格修饰的名词,若前文出现,或是店铺、住所、教堂,可以省略。
👉at the doctor’s(在诊所)、go to my uncle’s(去我叔叔家)
①I’m going to the butcher’s to buy some meat.
②We had dinner at the Smiths’ last night.
10. 名词后缀与词性转换
名词后缀,动词/形容词变名词核心:
▫️-tion/-sion(education)
▫️-ment(movement)
▫️-ness(kindness)
▫️-ity(reality)
▫️-ance/-ence(importance)
①Education is the key to success.
②Your kindness will never be forgotten.
③The importance of health cannot be overstated.
(二)名词的格与功能
11. ’s所有格与of所有格的使用场合
▫️’s所有格:多用于有生命名词;时间、距离、国家、城市也可用
例:today’s newspaper、China’s economy
▫️of所有格:多用于无生命名词
①Mary’s dress is more beautiful than mine.
②The roof of the house needs repairing.
③Tomorrow’s meeting has been canceled.
12. 名词在句中的语法功能
