My two sons have to go to school at seven o'clock every day对划线部分提问。划线部分也就是

go to schoo

你好，因为划线部分是go to school（去学校物嫌），所以对它（罩御手go to school）提问应该用what(什么）
所以问句是：
What do your two sons have to do at seven o'clock every day?
句子翻译是：你的两个儿子每天七点必须干什么？
have to：不得拆宽不，必须 every day：每天 at seven o'clock：七点钟
希望对您有用，祝你开心
望采纳谢谢
