肯定答：Yes, I am. 解析：含有`be`动词`are`的肯定句变一般疑问句，将`are`提到句首。主语`you`回答时用`I`。 学生常见错误提醒：写成“You are from Chengdu?” (语序未变) 或回答“Yes, you are.” (主格混淆)。 6. 参考答案：问句：Does Wang Jun live in Jinan? 肯定答：Yes, he does. 解析：主语`Wang Jun`是第三人称单数，谓语动词`lives`是实义动词，变一般疑问句需借助助动词`Does`，并将`lives`还原为原形`live`。`Wang Jun`是男性，回答用`he`。 学生常见错误提醒：写成“Is Wang Jun live in Jinan?” (误用`be`动词) 或 “Does Wang Jun lives in Jinan?” (动词未还原)。 7. 参考答案：问句：Are they having lunch at twelve o’clock now? 肯定答：Yes, they are. 解析：现在进行时（`are + having`）的肯定句变一般疑问句，将`be`动词`are`提到句首。`They`回答用`they`。 学生常见错误提醒：写成“Do they having lunch...” (误用`Do`) 或 “Are they have lunch...” (动词形式错误)。 8. 参考答案：问句：Is there a new post office near your school? 肯定答：Yes, there is. 解析：`There be`句型（单数主语`a post office`）变一般疑问句，将`be`动词`is`提到`there`前面。`our`变为`your`。 学生常见错误提醒：写成“Does there have a new post office...?” (误用`have`) 或 “Are there a new post office...?” (主谓不一致)。 9. 参考答案：When do you get up in the morning? / What time do you get up in the morning? 解析：对具体时间点`at six thirty`提问，用`When`或`What time`。主语`I`变`you`，需借助助动词`do`提问，动词用原形。 学生常见错误提醒：写成“When you get up...?” (缺助动词) 或 “What time does you get up...?” (主谓不一致)。 10. 参考答案：What does Noah’s father do? / What is Noah’s father? 解析：对职业`a taxi driver`提问，常用`What does... do?`或`What is...?`。 学生常见错误提醒：写成“What job is Noah’s father?” (超纲) 或 “Who is Noah’s father?” (混淆who和what)。 11. 参考答案：What is your favourite day? 解析：对事物`Tuesday`提问，用`What`。`My`变`your`。 学生常见错误提醒：写成“What your favourite day is?” (语序错误) 或 “Which is your favourite day?” (虽然也可，但What更基础)。 12. 参考答案：What does Liu Yi usually do after school? 解析：对动作`does her homework`提问，用`What`。主语`Liu Yi`是第三人称单数，需借助助动词`does`提问，动词还原为原形`do`。 学生常见错误提醒：写成“What does Liu Yi usually does after school?” (动词未还原) 或 “What Liu Yi usually do after school?” (缺助动词)。 13. 参考答案：What time is it now? / What is the time now? 解析：对时间`seven twenty-five`提问，用`What time`或`What is the time`。 学生常见错误提醒：写成“When is it now?” (不够精确) 或 “What time it is now?” (语序错误)。 14. 参考答案：How many books are there on the shelf? 解析：对可数名词的数量`forty-five`提问，用`How many`。`There are`变疑问句，将`are`提到`there`前。 学生常见错误提醒：写成“How many books there are on the shelf?” (语序错误) 或 “How much books are there on the shelf?” (`books`是可数复数，不能用`how much`)。 15. 参考答案：Where is Emma running? 解析：对地点`in the park`提问，用`Where`。现在进行时变疑问句，将`be`动词`is`提到主语`Emma`前。 学生常见错误提醒：写成“Where Emma is running?” (语序错误) 或 “Where is Emma run?” (动词形式错误)。 16. 参考答案：We are pupils. 解析：单数变复数，`I`变`We`，`am`变`are`，`a pupil`变`pupils`。 学生常见错误提醒：写成“We are pupil.” (名词未变复数) 或 “I are pupils.” (主语未变)。 17. 参考答案：The children mustn’t play on the streets. 解析：单数变复数，`The child`变`The children`（不规则变化），`street`变`streets`。 学生常见错误提醒：写成“The childs mustn’t play on the street.” (`child`复数错误) 或 “The children mustn’t plays on the streets.” (动词未变)。 18. 参考答案：These are my new dictionaries. 解析：单数变复数，`This`变`These`，`is`变`are`，`a dictionary`变`dictionaries`（以y结尾变ies）。 学生常见错误提醒：写成“These are my new dictionary.” (名词未变复数) 或 “This are my new dictionaries.” (主语未变)。 19. 参考答案：They have blue schoolbags. 解析：单数变复数，`He`变`They`，`has`变`have`，`a schoolbag`变`schoolbags`。 学生常见错误提醒：写成“They has blue schoolbags.” (动词未变) 或 “He have blue schoolbags.” (主语和动词都未变)。 20. 参考答案：问句：May you use my pen? 否定答：No, I may not. 解析：含有情态动词`may`的肯定句变一般疑问句，将`may`提到句首。主语`you`回答时用`I`。否定回答用`may not`。 学生常见错误提醒：写成“Do you may use my pen?” (误用助动词) 或 “Can you use my pen?” (虽然意思接近，但题目要求是`may`)。 21. 参考答案：问句：Does she always come to school before seven thirty? 否定答：No, she doesn’t. 解析：主语`She`是第三人称单数，谓语动词`comes`是实义动词，变一般疑问句需借助助动词`Does`，并将`comes`还原为原形`come`。 学生常见错误提醒：写成“Is she always come...?” (误用be动词) 或 “Does she always comes...?” (动词未还原)。 22. 参考答案：问句：Are there any computer rooms in the building? 否定答：No, there aren’t. 解析：`There be`句型（复数主语`computer rooms`）变一般疑问句，将`be`动词`are`提到`there`前面。`some`变`any`。 学生常见错误提醒：写成“Do there have any computer rooms...?” (误用`have`) 或 “Is there any computer rooms...?” (主谓不一致)。 23. 参考答案：问句：Is he doing his maths homework now?
