(疑问句语序错误) ✅ Did you watch TV? 记忆口诀： 否定疑问用did，动词原形跟后头。 错误六：be动词的否定形式写错 ❌ I weren't tired. (I应该用wasn't) ✅ I wasn't tired. ❌ She weren't at home. (She应该用wasn't) ✅ She wasn't at home. 记忆口诀： I/he/she/it用wasn't，you/we/they用weren't。 ✍️ 第二部分：精选练习题 一、单项选择 1. I ______ a movie yesterday. A. watch B. watched C. watches 2. She ______ at home last night.
