Most teachers agree that the first lesson of a teacher is often unforgettable.I remember getting into the class with the   1   of a beginner teacher: nervous, careful, excited…etc.The school I   2   my first lesson in was well-known to hold the most troublesome (顽皮的)students in the city.With this in   3  , I was more nervous than I should be.But I tried my best not to   4   it out and went into the class.The first thing I did was taking a look at the whole class.My eyes   5   on a big black student.He was sitting in the back   6   of the class with no one in front of him.His body was much   7   than mine.I thought it would be better to   8   that boy untouchable.As soon as I started my lesson writing on the blackboard, I heard some noise from the back.I   9  the students to find out who did it, but the class looked very   10  .I went on writing and the noise went on.Then I stopped my lesson to   11    this problem because I believed that if I lost control of the class from the   12   I wouldn’t be able to get it back.I thought the big boy made the noise.To my   13  , a small boy was the source (根源)of trouble.Days went   14   and I discovered that the big boy was good and quiet and the great source of trouble came from a group of   15   students who became under control after some weeks.From then on, I realized that judging (判断)by appearance can often be wrong, not only with students!
