Tyler was enrolled in my senior class for a semester.He had impulse-control（克制沖動(dòng)）and anger management issues.He had been suspended（停課）many times in previous years.When he entered my class，I assumed the worst.
    Tyler sat in the back row.Every time I talked in the front of the class，I would ask students questions，calling them by name.Unfortunately，every time I called on Tyler，he would respond with a glib（未經(jīng)思考的）answer.If he got an answer wrong，he would become angry.
    About a month into the year，I was still trying to connect with Tyler.I can usually get students involved in class discussions or at the least motivate them to sit quietly and attentively.By contrast，Tyler was just loud and offensive.
    He had been in so much trouble through the years.He expected his teachers to know about his referrals（移交）where he was sent to the office，and suspensions（停課），where he was given compulsory days to stay out of school.I had rarely found referrals to be effective because students would return from the office behaving worse than before.
    One day，Tyler was talking while I was teaching.In the middle of the lesson，I said in the same tone of voice， "Tyler，why don't you join in our discussion instead of having one of your own？" With that，he got up from his chair，pushed it over and yelled something.I can't remember what he said other than that he included several impolite words.I sent Tyler to the office with a discipline referral，and he received a week's out-of-school suspension.
    To this point，this was one of my worst teaching experiences.Tyler's anger was almost too much for me.The week Tyler was out of school was a wonderful time，and we got a lot accomplished as a class.However，the suspension week would soon come to an end，and I was fearful of his return.

Paragraph 2：
    A spark of surprise flashed across his face._________________
