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（實驗） 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 （神經(jīng)科學(xué)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：
此篇文章講述的是關(guān)于青少年生物鐘和上課時間的研究情況．文章中指出，青少年感動早起很困難，因為他們的生物鐘比成年人要長．所以他們在早上不想起也不是因為晚上不睡覺的緣故．所以，學(xué)校應(yīng)該適當(dāng)將上午上學(xué)時間延后．
解答 6．D，詞義猜測題，文中提到"their alarm"他們的鬧鐘，所以應(yīng)該是重新設(shè)定，選擇D．
7．D，推理判斷題，文中提到"Instead of starting school at 9am，students will begin the school day at 10am．"以前通常是早上九點，可是在英國，學(xué)校要求學(xué)生10點上課，選擇D．
8．C，推理判斷題，根據(jù)倒數(shù)第二段第一句Teenagers'sleep cycles，on average，begin two hours afteradults．青少年感動早起很困難，因為他們的生物鐘比成年人要長，所以選擇C．
9．A，考查細節(jié)理解．根據(jù)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年實驗的目的是找出是否晚上課可以提高學(xué)生成績，由此確定選擇A．
10．B，考查細節(jié)理解．根據(jù)全文內(nèi)容和文中的實驗可以總結(jié)出中心話題，并且可以用第五段的But science is telling us that teenagers need to sleep more in the mornings．文章聚焦的中心話題是：在早晨，學(xué)生們需要更長時間的睡眠，選擇B．
點評 對于閱讀表達題，一定要記得首先通讀全文，了解文章大意，然后再根據(jù)文章關(guān)鍵詞，關(guān)鍵句，掌握細節(jié)問題，并進行推理判斷，再去回答具體的問題．
