1.It's a scene in many homes around the world:tired-eyed teens wake to the sound of their alarm clock.Another school day begins,and we all wish we could have just one extra hour of sleep.
For lucky high school students in England,they're now going toreset their alarm and get an extra hour of sleep.Instead of starting school at 9am,students will begin the school day at 10am.
This is part of a huge study by Oxford University.The experiment(实验) will see whether later classes can improve exam results.
More than 100schools across England will join the four-year experiment,which includes tens of thousands of students.It is based on scientific evidence that teenagers are out of step with traditional school hours.
"We know that something funny happens when you're a teenager,"lead sleep researcher Colin Epsie told The Telegraph."Your parents think it's because you're lazy and everything would be OK if you could get to sleep earlier.But science is telling us that teenagers need to sleep more in the mornings."
Another experiment in 2009saw an improvement of 19percent in exam scores for major subjects-such as math and science.
Teenagers'sleep cycles,on average,begin two hours after adults.Neuroscientists (神经科学家) say teens have a built-in clock,which makes them more likely to go to sleep around midnight.As well as not feeling fully awake until between 9am and 10am.This body clock stays until the age of 19for females and 21for males.
Schools are places for learning,as well as education laboratories-finding out the best ways to learn and increase knowledge.Yet we'll have to wait until 2018to find out these exciting results!

分析 文章大意:
此篇文章讲述的是关于青少年生物钟和上课时间的研究情况.文章中指出,青少年感动早起很困难,因为他们的生物钟比成年人要长.所以他们在早上不想起也不是因为晚上不睡觉的缘故.所以,学校应该适当将上午上学时间延后.
解答 6.D,词义猜测题,文中提到"their alarm"他们的闹钟,所以应该是重新设定,选择D.
7.D,推理判断题,文中提到"Instead of starting school at 9am,students will begin the school day at 10am."以前通常是早上九点,可是在英国,学校要求学生10点上课,选择D.
8.C,推理判断题,根据倒数第二段第一句Teenagers'sleep cycles,on average,begin two hours afteradults.青少年感动早起很困难,因为他们的生物钟比成年人要长,所以选择C.
9.A,考查细节理解.根据第六段A similar experiment in 2009 saw an improvement of 19 percent in examscores for major subjects-such as math and science.2009年实验的目的是找出是否晚上课可以提高学生成绩,由此确定选择A.
10.B,考查细节理解.根据全文内容和文中的实验可以总结出中心话题,并且可以用第五段的But science is telling us that teenagers need to sleep more in the mornings.文章聚焦的中心话题是:在早晨,学生们需要更长时间的睡眠,选择B.
点评 对于阅读表达题,一定要记得首先通读全文,了解文章大意,然后再根据文章关键词,关键句,掌握细节问题,并进行推理判断,再去回答具体的问题.
