- she:特指女性人物;
- it:特指非人物
(动物、物品、天气、时间等)
单数名词 / 不可数名词 ① 单数可数名词
(如 my father、the cat、a pen);
② 不可数名词
(如 water、bread、milk) - 单数可数名词:单个具体的人 / 物,需搭配限定词(my/your/the/a 等)或直接表特指;
- 不可数名词:无复数形式,表 “整体 / 不可拆分的事物”,视为单数
单数人名 / 地名 / 机构名 ① 人名(如 Tom、Lucy、Miss Li);
② 地名(如 Shanghai、the zoo);
③ 机构名(如 the school、Sunny Primary) 特指单个、独一无二的人 / 地点 / 机构,无复数形式
不同第三人称单数的区别
不同第三人称单数
的核心用法
一、第三人称单数代词(he/she/it)
指代提前出现的人或物,直接作主语,无需额外修饰,动词必须变三单。
he/she 只能指代人,it 指代非人生物、物品、天气、时间、距离等。
用法口诀:男用 he,女用 she,非人事物全用 it。
he
she
it
二、单数名词 / 不可数名词
明确具体对象,强调 “单个 / 整体”
单数可数名词:必须是 “单个” 的人或物,常搭配限定词(my/your/the/a),动词变三单。
不可数名词:无论数量多少,都视为第三人称单数,动词变三单(无复数形式)。
关键:复数名词(如 dogs)、可数名词复数形式(如 apples)不算三单。
单数可数名词
1. 单个家人(my father)
2. 单个物品(the book)
3. 单个职业
(the teacher)
不可数名词
1. 食物(rice/milk)
2. 液体(water/juice)
3. 抽象事物(music/fun)
三、单数人名 / 地名 / 机构名
专属指代,独一无二
直接作主语,无需加 a/an(本身表特指),动词变三单。
多人名 / 多地名单数并列时(如 Tom and Lucy),视为复数,动词用原形。
机构名(如 the school)、地名(如 the park)也按此规则。
人名
地名
单个机构
