Dozens of school districts around the country…阅读及答案
编辑:顺风考试网   来源:网络  更新时间: 10:39 
Dozens of school districts around the country have been looking at these studies and are considering ways to adjust their class schedules.
Eric Peterson is head of St. George’s School, a private boarding school for grades 9-12 in the northeastern state of Rhode Island.
After looking at the medical research on adolescent sleep needs and observing students in his own school, Peterson consulted with Dr. Judy Owen, a famous pediatrician(儿科医师)and sleep expert.
Armed with what he considered to be convincing data. Peterson decided to change his school’s start time from 8:00 am to 8:30 am on a trial basis to see if a 30-minute change would make a difference. He was surprised by the results.
“What was really astonishing was how many benefits and how significant the benefits were,” he says. “In the research itself, we saw just over a 50 percent decrease in health-center admissions for fatigue, or fatigue-related illness, or rest requests. We saw almost a 35 percent decrease in first-period lateness. Students reported that they were more attentive. They were less sleepy during the day.”
And, according to Dr. Patricia Moss, assistant dean for Academic Affairs at St. George’s School, students weren’t the only ones reporting better results in the classroom. She says virtually all the teachers almost immediately notice much more concentrated in the classroom, and there was definitely a more positive mood all around.
“Kids were happier to be there at 8:30 than they were at 8:00, ” she says. “So our experience across the total spectrum was, universally, extremely positive and surprisingly so.”
Headmaster Peterson says there was another unexpected area of change when the school changed its start time.
“We saw probably a greater then 30 percent increase in student attendance at breakfast, and of the food that they were eating. We ate more than doubled the amount of milk, eggs, fruit and cereal. So it was quality breakfast foods that the kids were eating. So they were better fueled as well as better rested.”
Ross and Peterson acknowledge that making schedule changes has been easier at a small, private boarding school than it might be for the larger U. S. public school system. But they are hopeful that others will find a way.
“In the end.” Says Peterson, “schools ought to do what’s the right thing for their students, first and foremost , and this element of the program is very clear---certain for us as a school---but I think as a general example to other schools, is pretty convincing, and so I would argue that it’s worth doing.”

Cities Across The Country Are Running Out Of It : NPR英语翻译As students across the country have their yearly flu shots(打流感疫苗),doctors around the world are preparing against a possible outbreak of bird flu that few current vaccines(疫苗) will guard against,The likelihood of a bird flu spreading among humans is very high,the World Health Organization warned recently.European countries worry about bird flu very much,Since many migratory birds(侯鸟) start to fly back from the North.There are at least 15 different types of bird flu virus around the world.The possible outbreak maybe caused by a virus known as H5N1.It was first found to have spread from a bird to a human in Hong Kong in 1997.In addition to Asia,this bird flu has been found among birds in Romania,Turkey,Russia and Kazakhstan.The outbreak in 1997 in Hong Kong was quickly controlled,at a cost of 18 people iii and six dead.About 1.5 million chickens were collected in an effort to remove the source of the virus,But scientists say that the virus can change itself rapidly.Also,if the virus mixes with the human flu virus,it could be spread through person -to-person contact in the same way as ordinary human flu is spread.Bird flu can cause fever,coughing,sore throats and muscle aches in humans.With the introduction of vaccines,flu is not as deadly as it used to be.But throughout history it was a huge cause of death around the world.The outbreak of Spanish flu in 1918-19 killed about 40 to 50 million people worldwide.Currently there is no vaccine against bird flu that can be used on humans,Scientists are working to develop one.This will probably take several months to complete and may not be ready in time to stop a widespread outbreak of the disease.
