**Pronouns的定义**： Pronouns (代词) are words that are used to replace nouns (名词) or noun phrases (名词短语) in order to avoid repetition or for clarity. They can function as subjects, objects, determiners, or complements in a sentence. **主要用法**： 1. **作为主语**：主格代词（Subject Pronouns）用于代替名词作为主语，如 "I am a student." 2. **作为宾语**：代词可以用作动词或介词的宾语，如 "Please tell me where she has gone." 3. **所有格表示**：物主代词（Possessive Pronouns）用于表示所有关系，如 "This is my book." 4. **指代不确定性**：不定代词（Indefinite Pronouns）用于指代不确定的事物或人，如 "Some people like coffee." **例子**： * **主语用法**："He always helps me with my homework." (He is a subject pronoun.) * **宾语用法**："She gave me the book." (Me is an object pronoun.) * **所有格用法**："It's her cat." (Her is a possessive pronoun.) * **不定代词用法**："Anyone can succeed if they work hard." (Anyone is an indefinite pronoun.) **英语解释（约100词）**： Pronouns are linguistic tools that substitute for nouns to enhance the clarity and fluidity of speech or writing. They have various functions, such as acting as subjects, objects, or possessors. Common examples include "I", "she", "he", "it", "they", and possessive forms like "my", "your", "his", "hers". Indefinite pronouns like "someone" and "anything" are also part of this category, reflecting uncertainty or generality.
