In this way, I 2 a few tests. But one day something 3 happened. Our teacher changed our 4 for the exam and I was sitting beside a boy that I seldom 5 with before.

When he asked me what I wanted, I 8 asked him for the answers. To my surprise, he 9 without any hesitation (犹豫). Of course, I was really 10 at his behavior and thought badly of him. After the test he 11 me, telling me that I could get good grades in math and that all I needed was to put more 12 into studying the subject.

Time passed and I was getting many As in my math even till my higher studies. Till today, I am still 17 to my friend who didn' t allow me to copy his work. He 18 if he provided me with the "help" during the test, there would be no 19 for me to shine. So let others shine and don' t ever rob (掠夺) others of their opportunity to show their 20 . | ||||
