One night last February, a seventeen-year-old Duffy drove home along a winding road, he saw a strange light thrown against the tree. “I knew it wasn’t the moon”, he said. “I drive this road all the time and I notice little things out of place.”
Duffy stopped his car and got out to examine. Below him far down in the deep valley lay a broken car with its headlights on. Thirty minutes earlier, a man had driven off the edge of the road, which has no guardrail. His car fell and rolled end over end, landing on its top more than two hundred feet below.
Duffy rushed to call for help, then returned and got down to reach the injured driver. Snow covered the valley and the temperature was below freezing. After struggling back up the cliff, Duffy took off his jacket and shirt and wrapped the injured man in time, along with the blankets from his car.
Life-saving deeds are starting to become usual action for Duffy, the oldest of seven children. When he was 12, he saved his ten-year-old brother from drowning. Two years ago, his three-year-old sister ate rat poison, and Duffy cleaned out her mouth, make her drink milk to protect her stomach and called doctors.
“We have tried to teach the children good values, and it looks like we have got some reward for it.” His father says.

A Brown University sleep researcher has some advice for people who run high schools: Don’t start classes so early in the morning. It may not be that the students who nod off at their desks are lazy. And it may not be that their parents have failed to enforce (确保) bedtime. Instead, it may be that biologically these sleepyhead students aren’t used to the early hour.
“Maybe these kids are being asked to rise at the wrong time for their bodies,” says Mary Carskadon, a professor looking at problem of adolescent (青春期的) sleep at Brown’s School of Medicine.
Carskadon is trying to understand more about the effects of early school time in adolescents. And, at a more basic level. she and her team are trying to learn more about how the biological changes of adolescence affect sleep needs and patterns.
Carskadon says her work suggests that adolescents may need more sleep than they did at childhood, no less, as commonly thought.
Sleep patterns change during adolescence, as any parent of an adolescent can prove. Most adolescents prefer to stay up later at nigh and sleep later in the morning. But it’s not just a matter of choice –their bodies are going through a change of sleep patters.
All of this makes the transfer from middle school to high school—which may start one hour earlier in the morning ---- all the more difficult , Carskadon says. With their increased need for sleep and their biological clocks set on the “sleep late, rise late” pattern, adolescent are up against difficulties when it conics to trying to be up by 5 or 6 a.m. for a 7:30 a.m. first hell. A short sleep on a desktop may be their body’s way of saying. “I need a timeout.”
