As the monitor as well as one of the top students in my class, I am always a     1     (pride) boy. Sometimes I rely so much on myself that I won’t follow others’ suggestions. And it was because     2     my blind pride that I made     3     stupid mistake in a physics competition that needed not only personal ability but also teamwork. During the competition, I thought I performed     4     (well) than my partners and it was I that won the applause of the audience, so I forgot    5    (work) together with     6    (they). When our group were preparing for the last question, one of   my partners told me that there was something wrong with our last question’s answer and suggested     7    (check) it out. But I was so proud    8     I didn’t take his. To my surprise, our answer was wrong and we     9    (fail). If I had taken his advice at that moment, we would not have failed.    10    (experience) the failure, I realize that it is important to listen to others’ opinions.
