朋友,假如问你,敢向比你年龄小的同学挑战吗?你肯定不屑思考地说:敢。假如问你,敢向与你同龄的同学挑战吗?你也能自信地回答:敢。再假如问你,敢向比你年龄大的同学挑战吗?你恐怕得壮壮胆子,选选项目,才能说出:敢。那么假如竟然问你,敢向你的老师挑战吗?你将如何回答呢?是敢,还是不敢? If you ask friends, dare to challenge the younger classmates than you, you must say with daring thought: dare. If you are asked to dare to challenge your peers of the same age, you can also answer with confidence: dare. If you ask again, dare to challenge the older classmates, you may be courageous enough to choose the project before you can say: dare. So if you even ask you, dare to challenge your teacher? How would you answer it? Dare to dare or dare?
