Tyler was enrolled in my senior class for a semester. He had impulse-control (克制冲 动)and anger management issues. He had been suspended(停课)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（未经思考的）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, 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.
On the day of Tyler's return, I stood at the door awaiting him.

Childhood obesity puts kids at risk for cardiovascular disease, bone and joint problems, sleep apnea, and potential social and psychological problems. 1.
Of course, the CDC recommends healthy lifestyle choices—healthy eating, physical exercise. 2. That is to provide a safe and supportive environment where healthy lifestyle choices can be made.
What don't kids need?3.Too much focus on overweight leads toward more weight gain.
A new data analysis of two studies found that children whose parents considered them to be “overweight" tended to gain more weight over 10 years than children whose parents considered them “normal weight". Children whose parents label them as “overweight" had a negative self-perception about their bodies. They were engaged in more attempts to lose weight. 4.
The clear message from this study is that dieting is more likely to lead to weight gain, not weight loss, in both children and adults. Psychology researchers Eric Robinson and Angelina Sutin argue that the stigma of being labeled overweight as a child might actually gain weight in the future.
5. For the study, children's height and weight were measured at age 4 or 5, and parents were asked to describe whether they thought the children were best described as underweight, normal weight, overweight or very overweight. When the children were 12 or 13, they used images to best depict what they perceived their bodies to look like and were asked whether or not they engaged in any dieting behavior. Height and weight measurements were taken again when the children were 14 or 15 years old.
A.Labels and pressure around weight and weight gain.
B.Left untreated, these problems can continue into adulthood.
C.They also point out another important way to keep kids healthy.
D.The researchers cannot be certain about what is driving.
E.They analyzed the data from a study of Australian children.
F.But it actually contributed to weight gain over the 10-year period.
G.A number of mothers in this study suffer from depression and anxiety.
