(4个)___________ _________________ _________________ ________________Keys: may/have to/need/dare/had better等情态动词小笑话一美国教授在上课,有个学生问道: “Can I go to the bathroom?”教授回答: “I don't know. You must know if you can go to the bathroom.”这里学生想表达的意思很明显:我能去上厕所吗?教授当然也明白他的意思,只是故意逗他玩的.Can 也有表示"人具有某种能力",比如上厕所的能力。
所以教授说“我不知道(你有没有这个能力),你自己应该知道你有没有能力上厕所。
”其实跟人提请求用can是不太礼貌的,最好是说Could/May I或者Would you mind...等等,这也是教授跟他开玩笑的原因。
