6 完形填空。 I hated math and was really bad at it when I was young, so I found others to allow me to copy their work. Even though they knew they were 1 me, there were lots of people who were glad to"help". In this way, I 2 a few tests. But one day something 3 happened.

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. I was still 13 with him, but I couldn"t get his words out of my mind. From that day on, I began to 14 more time to my math.
