肯定答：Yes, he does. 解析：主语是第三人称单数“Lucas”，谓语动词是“helps”，变一般疑问句需在句首加“Does”，并将helps还原为动词原形“help”。Lucas是男性，回答用he。 学生常见错误提醒：写成“Is Lucas often help...?” 或“Does Lucas often helps...?”。 5. 参考答案：问句：Does Wang Jun want to join the art club? 肯定答：Yes, he does. 解析：主语是第三人称单数“Wang Jun”，谓语动词是“wants”，变一般疑问句需在句首加“Does”，并将wants还原为动词原形“want”。Wang Jun是男性，回答用he。 学生常见错误提醒：写成“Is Wang Jun want to...?” 或“Does Wang Jun wants to...?”。 6. 参考答案：问句：Are the monkeys jumping in the tree? 肯定答：Yes, they are. 解析：现在进行时“are jumping”变一般疑问句，将be动词“are”提到句首。主语是复数，回答用they。 学生常见错误提醒：写成“Do the monkeys jumping...?” 或“Are the monkeys jump...?”。 7. 参考答案：问句：Do they have long tails and big ears? 肯定答：Yes, they do. 解析：题目要求用they的复数形式提问。原句是“She has...”，改成复数句为“They have...”。对“They have...”提问，用“Do they have...?”。同时，单数名词“a long tail, a big ear”要相应变为复数“long tails, big ears”。 学生常见错误提醒：忽略单复数转换，写成“Does she have...?”。或忘记将has改为have，写成“Do they has...?”。 8. 参考答案：What subjects do you like? 解析：对喜欢的学科“English and music”提问，用“What subjects...?”。主语I变为you，助动词用do。 学生常见错误提醒：写成“What do you like?”（不具体）或“What subjects you like?”（语序错误）。 9. 参考答案：What is he like? 解析：对人（He）的外貌或性格特征“a friendly boy”提问，用“What is ... like?”固定句型。 学生常见错误提醒：写成“How is he?”（询问状态）或“What does he like?”（询问喜好）。 10. 参考答案：What are the tigers doing? 解析：对正在进行的动作“running and playing”提问，用“What ... doing?”。主语是复数，be动词用are。 学生常见错误提醒：写成“What do the tigers do?”（问习惯）或“What the tigers are doing?”（语序错误）。 11. 参考答案：When do you have lessons? 解析：对时间“on Monday and Wednesday”提问，用“When...?”。主语We变为you，助动词用do。 学生常见错误提醒：写成“What time do you have lessons?”（具体时刻）或“When you have lessons?”（漏助动词do）。 12. 参考答案：Who is good at playing football? 解析：对人“Noah”提问，用“Who”。谓语动词是is，who作主语时视为单数，动词保持原形is。 学生常见错误提醒：写成“Who are good at...?”（误用复数动词）或“Who is good at playing football?”但忘了去掉原句主语“Noah”。 13. 参考答案：How often do you help your little sister with her homework? 解析：对频率副词“always”提问，用“How often...?”。主语I变为you，助动词用do。 学生常见错误提醒：写成“When do you help...?”（问时间点）或“How do you help...?”（问方式）。 14. 参考答案：We are good students. 解析：单数变复数，I变为We，am变为are，a good student变为good students。 学生常见错误提醒：student的复数直接加s，注意拼写。忘记将a去掉。 15. 参考答案：The birds are flying in the sky. 解析：单数变复数，The bird变为The birds，is变为are。 学生常见错误提醒：bird的复数直接加s。注意be动词也要随之改变。 16. 参考答案：These elephants have long noses. 解析：单数变复数，This变为These，elephant变为elephants，has变为have，a long nose变为long noses。 学生常见错误提醒：elephant和nose的复数直接加s。注意将a去掉，并且动词has要变为have。 17. 参考答案：问句：Is the rabbit cute? 否定答：No, it isn't. 解析：含有be动词“is”的肯定句变一般疑问句，将is提到句首。主语The rabbit用it指代回答。 学生常见错误提醒：写成“Does the rabbit cute?” 或答语“No, it doesn’t.”。 18. 参考答案：问句：Does Liu Yi have a new computer? 否定答：No, he doesn't. 解析：主语是第三人称单数“Liu Yi”，谓语动词是“has”，变一般疑问句需在句首加“Does”，并将has还原为动词原形“have”。Liu Yi是男性，回答用he。 学生常见错误提醒：写成“Is Liu Yi have...?” 或“Does Liu Yi has...?”。 19. 参考答案：问句：Are you playing computer games? 否定答：No, I'm not. 解析：现在进行时“are playing”变一般疑问句，将be动词“are”提到句首。主语You回答用I。 学生常见错误提醒：写成“Do you playing...?” 或答语“No, I don't.”。 20. 参考答案：问句：Does Emma often wash her clothes? 否定答：No, she doesn't. 解析：主语是第三人称单数“Emma”，谓语动词是“washes”，变一般疑问句需在句首加“Does”，并将washes还原为动词原形“wash”。Emma是女性，回答用she。 学生常见错误提醒：写成“Is Emma often wash...?” 或“Does Emma often washes...?”。 21. 参考答案：问句：Does Lucas want to join the music club?
