When a big exam is coming up, you probably feel anxious about any wasted time and want to begin school as soon as you probably can.
But tens of thousands of British high school students will soon be getting up later. They’re taking part in a new experiment by Oxford University to see if later classes can improve their exam results.
Grades 10 students in the UK have to take the nationwide General Certificate of Secondary Education (GCSE) exams. They have to pass these exams in order to study more advanced courses, and later apply for universities.
The Oxford University project means that GCSE students from more than 100 schools across England will start school at 10 am, more than one hour later than the current start time (8:50 am).
The project is based on scientific evidence that teenagers are “out of sync(同步)” with traditional school hours, the Telegraph reported. And what they need is more sleep in the morning.
“We know that something funny happens when you’re a teenager, in that you seem to be out of sync with the world,” said professor Colin Epsie, who is leading the study. “Your parents think it’s because you are lazy and opinionated(固执己见的)and everything will be OK if you could get to sleep earlier. But science is telling us that teenagers need to sleep more in the mornings.”
Everyone follows a natural cycle of sleep and wakefulne ss. Biology has decided that teenagers go to sleep around midnight and don’t feel fully awake until 9-10 am, according to scientists. That’s two hours later than adults. And their body clocks stay like this until the age of around 21 for males, and 19 for females.
“Society provides school for learning, but the brain provides sleep. So we are exploring the possibility that if you delay the schools start time until 10 am, that will improve learning performance,” said Epsie.
The results could be positive, based on previous studies.
An early study at the UK’s Monkseaton High School in 2009 found that starting an hour later improved grades in core subjects by 19 percent.
The Oxford project is expecting to publish the results in 2018. It’s time to wait and see whether scientists will give us an excuse to get up late.
24. According to the article, students who take part in the Oxford University project_______.
A. will start school one hour earlier
B. will no longer have to take GCSE exams
C. will perform better academically than those who don’t participate
D. will be guaranteed more sleeping time in the morning
25.The underlined phrase “out of sync”in Paragraph 5 probably means _____________ .
A. breaking the habit of doing something B. getting used to doing something
C. having no idea of something D. having trouble keeping up with something
26. What is the author’s attitude toward the Oxford University project ?
A Critical B. Optimistic C. Doubtful D. Uninterested
27. What’s the best title of the article ?
A. Wake up late to excel B. It’s never too late to learn
C. The later you get up, the better you’ll learn D. An excuse to get up late

徐梦莘,字商老,临江人。幼慧,耽嗜经史,下至稗官小说,寓目成诵。
绍兴二十四,年举进士。历官为南 安军教授。改知湘阴县。会湖南帅括田,号增耕税,他邑奉令惟谨。梦莘独谓邑无新田,租税无从出。帅恚其私于民,欲从簿书间攈摭其过,终莫能得,由是反器重之。
寻主管广西转运司文字。时朝廷议易二广盐法,遣广西安抚司干官胡廷直与东西漕臣集议于境。梦莘从行,谓:“广西阻山,止当仍官般法,则害不及民。广东诸郡并江,或可容客贩,未宜遽以二广概行。”议与廷直不合。廷直竟遂其说,以客贩变法得为转运使。梦莘既知宾州,犹以前议为梗法,罢去。不三年,二广商贾毁业,民苦无盐,复从官般法矣。
梦莘恬于荣进,每念生于靖康之乱,四岁而江西阻讧,母襁负亡去得免。思究见颠末,乃网罗旧闻,荟萃同异,为《三朝北盟会编》二百五十卷,自政和七年海上之盟,讫绍兴三十一年完颜亮之毙,上下四十五年,凡曰敕、曰制、诰、诏、国书、书疏、奏议、记序、碑志,登载靡遗。帝闻而嘉之,擢直秘阁。zxxk
梦莘平生多所著,有《集补》,有《会录》,有《读书记志》,有《集医录》,有《集仙录》,皆以“儒荣”冠之。其嗜学博文,盖孜孜焉死而后已者。开禧元年秋八月卒,年八十二。

High-tech machines have made life easier for millions around the world.However, some people still prefer low-tech ways of doing things.Here’s an example of why this is happening.You can microwave a frozen hamburger in 60 seconds.However, it won’t taste as good as one you cook on the stove.And if you’re in that much of a hurry, you probably won’t take time to toast the bun.High-tech cooking saves time, but it doesn’t make for better-tasting meals.
Most people get their news from high-tech sources like television or the Internet.This has many advantages.For example, electronic news is more up to date than newspapers or magazines.It’s also more exciting to see live and videotaped news events than photographs.However, newspapers and magazines have some important advantages.They give more background and details.They also let you read the parts that are important to you and skip the rest.
Other high-tech timesavers have similar disadvantages.For example, most people use the phone or e-mail to stay in touch with friends and family members who live in other places.But when you use the Internet or the phone, you won’t always think carefully about what you are saying, and sometimes you forget the important things you want to communicate.Similarly, when you word-process a homework assignment instead of handwriting it, you can check your spelling electronically and put in fancy headings.However, some students are so busy with the computer that they don’t pay enough attention to the actual words they are writing.
21.Which of the following statements is TRUE according to the passage ?
A.The writer likes high-tech cooking
B.Low-tech cooking produces better-tasting meals.
C.High-tech news programs always keeps you reading what is important to you.
D.Handwritten homework is better than word-processed homework.
22.How does the writer feel about high-tech tools?
A.Better late than never. B.Easy come, easy go.
C.Every coin has two sides. D.Learn to walk before you run.
23.What is the main subject discussed in the text?
A.High-tech vs low-tech.
B.Advantages vs disadvantages.
C.Newspapers and magazines vs television and the Internet.
D.Word-processing vs handwriting.
24.How is the text organized?
A.Main idea-Argument-Explanation
B.Opinion-Discussion-Description
C.Topic-Comparison-Supporting examples.
D.Introduction-Supporting examples-Discussion.

Mike was one of my father’s younger brother. He has been died of cancer for two years. When I was a teenager, he taught us how to hunt in the woods used the hours before dawn. We usually left home at three o’clock in the morning, stayed in local restaurant for breakfast, and then travel on to one of his hunting destinations. Just after dawn, he would find the right spot in the woods. He would show me how not to make a sound and a movement. Though I never hunted an animal successfully, but I learned to be brave and patiently through the experience.

啃指甲这种“小毛病”,常常有人会无意识地去犯。很多分析人士都认为说话摸鼻子是撒谎,① 。但现在有研究表明,啃指甲并不一定是因为压力而带来的“小习惯”。其实,② 。因为他们太追求完美了,③ ,所以很难让自己放松下来,不能以平和的心态去完成一件事,或是某个工作事项及相关任务。当无法完成心中所想达到的目标时,他们就会比普通人更容易产生挫败感,缺少耐心,也就更感无聊。而此时他们的身体就会做出一些强迫的重复性动作,而啃指甲则是最常见的行为。
