一個人的一生中有許許多多的失敗與挫折，有時一點小事都可能讓一個人終身難忘。

There are many failures and frustrations in a person's life. Sometimes a little incident can make a person unforgettable.

一次，我數(shù)學小測試考的不好，情緒十分低落。這時，劉老師找到我，讓我到她的辦公室訂正試卷。我一看試卷，錯的正是那被我改了好幾遍的選擇題。我想起那天考試的情形：試卷做的很仔細，寫完后又認真地檢查了幾遍，老覺得選擇題有些不對于是就做了改動，把我自己都弄糊涂了感到自己學的還是不夠扎實。想到這里，我不禁流下了會很的眼淚，可是又有什么辦法呢？世上沒有后悔藥，現(xiàn)實就是現(xiàn)實，過去的事是永遠無法改變的?；氐郊?，媽媽知道后，不但沒有責怪我，反而鼓勵說：“這次別灰心，把基礎知識學好再闖下一關。”

Once, I did not do well in the math test, and I was very depressed. At this time, Miss Liu found me and asked me to revise the paper in her office. As soon as I look at the paper, the wrong one is the multiple choice question which I have changed several times. I think of the exam that day: the exam paper was carefully done, and I carefully checked it several times after I wrote it. I always felt that if the multiple-choice questions were not right, I had to make changes, which confused me, and I felt that what I learned was not solid enough. Thinking of this, I can't help but shed tears, but what can I do? There is no regret medicine in the world, reality is reality, and the past can never be changed. When I got home, my mother didn't blame me. Instead, she encouraged me to say," don't lose heart this time. Learn the basic knowledge well and go to the next level."

我聽了，心里的那片烏云就這樣被抹掉了。

When I heard it, the dark cloud in my heart was erased.
