情态动词本身有一定的词义，表示说话人的情绪，态度或语气。

   
can是情态动词，表示“能，会”。

如果是询问某人能不能做某事,则要使用其疑问形式, 即将can提至句首, 用Yes或No进行回答。

    其肯定回答是:

   
Yes, 主语(人称代词形式)+ can。

    其否定回答是:

    
No, 主语(人称代词形式)+ can’t。

  —
Can he drive a car?

      
他会开汽车吗？

  —
Yes, he can. / No, he can’t.

      
是的,他会。/不,他不会。

(1) can表示体力和脑力方面的能力，或根据客观条件能做某种动作的"能力

"。例如：

 ___________________________________________  你会骑自行车吗？

 ___________________________________________  要帮忙吗？

(2) can用在否定句和疑问句中时有时表示说话人的"怀疑""猜测"或不肯定。例如：
