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!
