根据短文内容，回答下列问题。
Life is full of regrets. The most
regrettable moment of my past years happened in my junior high school. At that
time, I failed my English exam.
On a winter afternoon, I sat on my seat and
waited for the English exam. It was the last exam of the semester. After the exam,
we would enjoy our winter holidays. I didn't worry about the exam because I was
good at English. And I was the so-called top student in my class. I thought it
was not necessary to review English. In my opinion, it would be easy.
Soon the teacher entered the classroom
several minutes in advance（提前）. Then
she gave out the test papers to us. At first, I thought it was easy. However, when
I finished half the paper, I felt it was increasingly difficult. I had ever
learned some words but I just could not remember them.
What's worse, I was influenced by these
difficulties and my brain was in a mess. I knew that I would fail the exam. I
regretted not preparing well for it. And I regretted being too proud of myself.
Two hours passed quickly, and we all had to
hand in our test papers. After school, I walked on the way home with a heavy
heart. The experience taught me a lesson, "Hard work is the only key to
good results."
