**Pronouns的定义**： Pronouns are words that are used in place of nouns in a sentence. They allow us to avoid repetition of the noun, or to emphasize a specific element in a sentence. **主要用法**： 1. **代替名词作为主语** (Subject Pronouns): They often appear before verbs in a sentence. For example, "I am a student." 2. **作为宾语** (Object Pronouns): They can function as the object of a verb or a preposition. For instance, "Please tell me where she has gone." 3. **作主语时，谓语动词需与主语保持一致** (Verb Agreement): The verb following a pronoun as a subject must agree with the pronoun's number. For example, "They were complaining about her." **例子**： 1. **人称代词** (Personal Pronouns): - Subject pronouns: I, you, he, she, it, we, they. - Object pronouns: me, you, him, her, it, us, them. 2. **指示代词** (Demonstrative Pronouns): this, that, these, those. **归纳**： Pronouns are versatile words that help us construct sentences more efficiently. They come in various forms, such as personal, demonstrative, and more, and serve distinct purposes in sentences, including replacing nouns and linking subjects with verbs. With a diverse set of pronouns in English, we can create clear and concise expressions.
