Question

jack does his homework with his new pen改一般疑问句

Answer 1

一般疑问句是:
Does Jack do his homework with his new pen？
分析:
句子中的does是谓语动词，意思是“做”，是实义动词，不是助动词。
此句是一般现在时态，主语Jack是第三人称单数形式，谓语动词does也是第三人称单数形式。
变成一般疑问句时，要在句子前加助动词does，原句子中的does要变成原形do.原句中的does不能去掉。

Answer 2

改一般疑问句：Does Jack do his homework with his new pen？

Answer 3

Does Jack do his homework with his new pen ？第一个does 为助动词，第二个do 就是做作业does 变为动词原形。
