Surveys of American teenagers find that about half of them do not get enough sleep on school nights. They get an average of 60 to 90 minutes less than experts say they need.

Experts say teens are biologically programmed to go to sleep later and wake up later than other age groups. Yet many schools start classes as early as seven in the morning.

As a result，many students go to class feeling like Danny，16 years old. He plays two sports，lacrosse and football. He is an active teen—except in the morning. DANNY：“Getting up in the morning is pretty terrible. I’m just very out of it and tired. And through first and second period I can hardly stay awake.”

Michael Breus，a clinical psychologist with a specialty in sleep disorders says：“These aren’t a bunch of lazy kids—although，you know，teenagers can of course be lazy. These are children whose biological rhythms，more times than not，are off.”Teens，he says，need to sleep eight to nine hours or even nine to ten hours a night. He says sleepy teens can experience a form of depression that could have big effects on their general well-being. It can affect not just their ability in the classroom but also on the sports field and on the road because any tired driver is dangerous，especially a teenager with a lack of experience.

So what can schools do about sleepy students？The psychologist says one thing they can do is start classes later in the morning.

Eric Peterson，head of St.George’s School in the northeastern state of Rhode Island，says，“In the end，schools ought to do what’s the right thing for their students，first and foremost.”And he wanted to see if a 30-minute delay would make a difference. It did.

A. Persona haibits.                    B. Early school hours.

C. Sports activities.                    D. Too much home work.

According to Michael Breus，          .

A. Teenagers are too lazy to get up early for school.

Watch out, Yahoo．There’s search engine out there with super speed and accuracy．It’s really cool．

Google is the Web’s largest search engine．In just two years it has gained a reputation for surprising speed and accuracy, delivering exactly what you’re looking for in a second．The site now does this 40 million times a day – a number achieved without spending a penny on a TV or newspaper ad．

Google doesn’t need them．In the past six months alone, the site has won a Webby （the online version of the Oscar） for technical excellence, set a new record for search engines by indexing a billion Web pages．

Yahoo still has 10 times the audience, but Google consistently ranks first in customer satisfaction: 97% of users find what they’re looking for most or all the time．“You see people smile when they use it, like they’ve found something no one else knows about,” says Danny Sullivan, editor of an online newsletter．

No one is smiling more than Larry Page, 27, and Sergey Brin, 26, who seem certain to become billionaires when the company goes public, probable sometime next year．They make a great comedy duo．When they first met as Ph．      D．students, the pair say, they found each other horrible – “I still find him horrible,” adds Brin – but were driven together by a computer – science project aimed at coming up with better ways of searching the Web．

The idea behind Google is that traditional search engines are stupid．They think relevance is based on repetition; if you type in a request for Tiger Woods, say, you’ll get websites listed according to how many times those words appear．Not only is this no guarantee of quality, but it’s also open to abuse．If you own a Tiger fan site and want to lead more people to it, simply type his name thousands of times in the site’s source code．

Pupils remember more and behave better when 3D images are used in lessons, research suggests. They are quicker to learn and absorb new concepts, and display higher levels of concentration.

Professor Anne Bamford, of the University of the Arts, London, studied the effectiveness of 3D content in 15 schools across seven countries, including the UK. Pupils in 3D classes could remember more than those in the 2D classes after four weeks, improving test scores by an average 17 percent compared with eight percent for 2D lessons. They gave more detailed answers to the tasks and were more likely to think in 3D, using hand gestures and mime (模仿動作) to answer the test questions successfully.

 

 

The teachers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engagement in the lessons

Children are used to 3D with the rise of computer games that use the technology—90 percent of those in the study had seen a 3D film. Schools would need 3D-enabled projectors（投影儀）, laptops with good picture capabilities, 3D software and glasses for children to introduce animations (動作) into classrooms.

But Danny Nicholson, an educationist, said the technology would be impractical to use in schools and could be too expensive. He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick (小玩意兒). There are a few cases where a true 3D image might help, but most of the time, good 2D models that can be moved , would be just so effective.”

In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms. And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils. Those who watched the 3D presentations were more engaged and reported a general increase in their interest in science compared with students who watched the 2D version.

1.Teachers think pupils in 3D classes       .

A. are naughtier than those in 2D classes        B. have less motivation

C. find it hard to concentrate                 D. have deeper understanding

2.Danny Nicholson tends to think that       .

A. many pupils prefer 2D models

B. 3D is a bit expensive for some schools

C. true 3D images would not help in classes

D. 3D technology has a bright future in classes

3.What can we learn from the last paragraph?

A. 3D classes will soon be given in one school district in Colorado.

B. Teachers will use the 3D technology through specific training.

C. Many pupils are now more interested in science than before.

D. 3D technology will replace 2D models in the future.

4.What is the text mainly about?

A. 2D models are always more effective than 3D images.

B. The differences between 3D and 2D images.

C. How schools can make full use of 3D technology.

D. Pupils behave better when 3D images are used in classes.

5.Where is the text most probably taken from?

A. A history book.    B. A news story

C. A science magazine.   D. A school report.

 

 

 Danny________ hard for long to realize his dream and now he is popular.

A. works           B. is working            C. has worked           D. worked

A Special Relationship

This novel is about a woman whose entire life is turned upside down in a very foreign place despite the fact that people there speak her language. Sally Good child is a 37-year-old American who, after nearly two decades as a highly independent journalist, finds herself pregnant and in London. She married an English foreign correspondent, Tony Thompson, whom she met while they were both on assignment in Cairo. From the beginning, Sally’s relationship with both Tony and London is an uneasy one: She finds her husband and his city to be far more foreign than imagined. But her adjustment problems soon turn into a nightmare(噩夢). She discovers that everything can be taken down and used against you, especially by a spouse (配偶) who now considers you an unfit mother and wants to prevent you from ever seeing your child again.

       When the young officer investigating(調查) the case notes that some of the evidence points to murder rather than suicide(自殺), Sayre finds herself unable to leave Destiny.
