在疑问句中不需要借助助动词。将can直接提前，变为疑问语序。
语法概述：
1.can是常见的情态动词，不能独立作谓语，其后需接动词原形。
2.它没有人称和数的变化。
3.can的否定形式为can not, 其缩略形式为can’t/cannot, can’t多用于口语，cannot更加正式。
4.can可表示能力、推测、允许、请求等，本单元主要讲解can表示能力的用法。
情态动词can的用法
can表示能力时，意为“能；会”。
“can+动词原形”表示“（某人）能/会做某事”;
其否定形式为“can’t/cannot+动词原形”，表示“（某人）不能/不会做某事”。
can表示能力的用法
I can play basketball, and my brother can play football. 我会打篮球，我哥哥会踢足球。
She can play the piano, but she can’t/cannot dance.
她会弹钢琴，但不会跳舞。

否定句 主语 + can’t/cannot + 动词原形+其他.
He can’t/cannot play the piano. 他不会弹钢琴。
一般疑问句 Can + 主语 + 动词原形 + 其他
肯定回答：Yes, 主语 + can.
否定回答：No, 主语 + can’t.
—Can he play the piano 他会弹钢琴吗？
—Yes, he can. 是的，他会。/No, he can’t. 不，他不会。
