💡 Simple HSK1 Lesson: 是 / 对 / 好 These 3 words are super common for beginners but easy to mix up! Here is the simplest rule: 1. 是 (shì) = Am / Is / Are Used to define, explain identity (who/what something is). Example: 我是学生。(I am a student.) 2. 对 (duì) = Correct / Right Used to judge if an answer or opinion is right. Example: 你是对的。(You are right.) 3. 好 (hǎo) = Good / OK / Fine Used to describe quality or agree with a suggestion. Example: 很好！(Very good! / OK!)
