根据短文理解，选择最佳答案。 Do you think there is a ghost(鬼) in the world? More than 20 years ago, a student jumped from the top of the clock tower in the University of Birmingham. He did this only because he failed his final exam.
After his death, a superstition(迷信)began: Anyone who walks under the clock tower will have bad luck in his exam. Years later, students there still remembered the story of the tower. Although Birmingham is the second largest city in Britain, the university is green and quiet. The grass around the tower has been worn away by the feet of students who refuse to pass underneath the tower.
The university had to pave(铺)extra paths, so students could walk to their classrooms without passing under the most terrible area. But, one day just before an important exam, a top student in the university walked under the clock tower because he was lost in thought.
However, he got high marks in the exam the next day. Quickly students all knew about it. Then they realized that the most important thing is working hard.
Whenever I go under the clock tower, I will tell myself, “Working hard is the key to success.”
