肯定答：Yes, it is. 解析：含有 be 动词`is`的肯定句变一般疑问句，将`is`提到主语`the classroom`前面。回答时主语`the classroom`用`it`代替。 学生常见错误提醒：写成“The classroom is clean and tidy?” (语序未变) 或 “Does the classroom clean and tidy?” (误用助动词`does`)。 5. 参考答案：问句：Do you have a new bag? 肯定答：Yes, I do. 解析：含有实义动词`have`的肯定句变一般疑问句，主语是`you`，需借助助动词`Do`放在句首。回答时主语`you`用`I`。 学生常见错误提醒：写成“Have you a new bag?” (不符合实义动词变疑问句规则) 或 “Are you have a new bag?” (误用`are`)。 6. 参考答案：问句：Does Emma want to visit the zoo? 肯定答：Yes, she does. 解析：含有实义动词`wants`（第三人称单数形式）的肯定句变一般疑问句，需借助助动词`Does`，并将`wants`恢复为原形`want`。`Emma`是女孩名，回答用`she`。 学生常见错误提醒：写成“Is Emma want to visit the zoo?” (误用`is`) 或 “Do Emma want to visit the zoo?” (主语是第三人称单数，不能用`Do`)。 7. 参考答案：问句：Are they glad to see you?
