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 can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿动作) 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(投影仪),laptops with good picture capabilities,3D software and glasses for children to introduce animations(动作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use in schools and could be costly.He said,“While I think the idea of 3D technology is very interesting, I worry that 3D is a bit of an expensive gimmick(小玩意儿).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 as effective.”
In the US,one school district in Colorado 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 engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.

举一反三
Scientists are claiming that they have now separated unusual ingredients in a rare seaweed discovered by fishermen off the coast of Korea that offer incredible health benefits—including the ability to restore blood pressure to normal levels.
Dr. Haengwoo Lee, a famous biochemist conducted a clinical study on these two ingredients. The first is Seanol, an extremely rare seaweed extract(浓缩物) from Ecklonia Cava that"s proven to be 100 times more powerful than any land-based antioxidant(抗氧化剂). That"s because it stays working in your body for 12 hours, compared to land-based antioxidants that work for 30 minutes. "Its secret is its make-up of special chemicals that are a huge 40% fat soluble( 可溶的)," Dr. Lee explains. "Unlike nearly all land-based antioxidants that are water soluble, Seanol"s protective compounds can get into things like the fatty tissues of your brain and penetrate(渗透) all three layers of your cells, including the outside, the oil-based cell membranes(细胞膜), and your DNA." Indeed, Seanol is so powerful, it"s the only FDA-approved Ecklonia Cava marine-algae (海藻) extract in existence.
The second ingredient is Calamarine, a deep-sea omega-3 discovery that delivers 85% more DHA omega-3s to your heart, brain, joints, and eyes. It"s known to reduce the problems from tiredness and poor memory, joint pain, mood swings and depression.
With that research in mind, Dr. Lee combined Seanol and Calamarine with a high dose of vitamin D to form Marine-D3, the newest supplement in the fight against age-related illnesses and high blood pressure.
Dr. Lee found that Calamarine delivers some of the greatest concentration of omega-3s known to science. Combined with Seanol"s ability to reduce body inflammation(炎症), as well as help cells get the nutrients they need to thrive, stay healthy and protected, Marine-D3 is able to boost a body"s entire well being.
The makers of Marine-D3 are so confident that you"ll see fast dramatic results from this product, that if you aren"t happy after two full months, simply return the unused portion and they"ll buy it back. They"ll even give you ten dollars extra just for giving it an honest try! That kind of faith, combined with Dr. Lee"s exhaustive research, shows that Marine-D3 really is a one-of-a-kind product.

All of a sudden, a young man got inside the cab. He took her handbag in which she had put her visa, passport, and all the money for the trip.
The cab driver, who was in collusion with the robber, left her in the exactly middle of a dark street. She thought that she was rather unfortunate in the very situation.
During the very night, she was told a piece of shocking news. Tears came down her cheek. Flight 360, the plane that she should have got on board, had crashed. Had she not lost her important belongings, she could surely have lost the thing far more precious——her life.
Sometimes bad things really happen. There are times when nothing seems to go our way. So what should we do about it? We must get rid of all these frustrations and start all over again in the faith that we will get what we deserve.
Don’t waste your time and energy on things that can’t be changed. Continuous worrying will only affect your health and you’ll be doing much more damage than what was previously done.
What if it was the other way round? What if we never ran out of good luck?
There was a man who won the lottery. He became greedy and wasted all his money on everything he could get his hands on.
But when he one day made it to the front page of the newspaper again, it was a different story. He had been killed because of his riches. If you attain good luck, you can never be too secure about it. Life is so unpredictable. You never know what will happen next.
Live one day at a time. We sometimes subject ourselves to unnecessary emotional trouble. But please don’t forget: sometimes misfortune can be the source of happiness. Live for the moment. Do what must be done for the present and the future will turn out just fine. Believe me. And believe in yourself. As Captain Planet always says, “The power is yours!”

Probably TV really educates us. For example, we can learn a very useful medical fact: A man that has been shot always has time to speak a broken sentence when he is dying. “The killer was…” (dies)
But I suppose the biggest things that we learn from TV can be regarded as “Life Skills”. Bad things simply happen on either stormy or dark nights. Emotional breakdowns make people wander in the heavy rain without raincoats or umbrellas. And contrary to the scientists, the crack of lightning and the accompanying flash come on at exactly the same time, wherever the scenes are.
I’ve even got to know useful geographical facts from science-fiction shows: Aliens only speak the language of English no matter which planet they come from.
To make good use of something that we learn from TV can make our security better. Consider these truths. When you are really attacked by 20 bad guys, you needn’t worry about your being outnumbered. The criminals will hang back and take turns to approach you in ones and twos just so you can conveniently defeat them all. Bad guys who are completely covered in black clothes always remove their black masks to reveal that they are in fact, aha, women.
TV often teaches us a lot of important information as well about escaping from danger. Watch and learn. (1) If anyone is running after you down a passage, you will find that boxes have been conveniently placed near all the walls you need to jump over. (2) If you are tall and handsome, you can run from any number of armed criminals, and every shot will miss you.
Be warned, however, if your name card says “henchman” (帮凶) and you are part of a group of plain-looking people trying to catch a handsome individual, a single shot will kill you. But don’t be anxious: TV also delivers useful information for bad guys. All cars are inflammable (易燃的) and have amazing shock absorbers that enable them to fly into the air and land without damage — except police cars.
TV even teaches us about TV. Whenever anyone turns on a TV, it shows a news flash about someone they know. They then turn the box off immediately after that news item.
小题1: When the writer says “A man that has been shot always has time to speak a broken sentence when he is dying” (Paragraph 2), he shows his________.
A.humor | B.sympathy | C.deep concern | D.medical knowledge |
A.bad things cause people to break down in the rain |
B.bad things never happen on dark and stormy nights |
C.people with emotional problems like to walk in the rain without umbrellas |
D.you can’t hear the crack of lightning and see the accompanying flash exactly at the same time |
A.The program shown is always about the importance of TV. |
B.The person always turns off the TV when it’s time for news. |
C.The news shown is always about someone the person knows. |
D.TV always shows news about famous people. |
A.Life skills can be learned from TV. |
B.What happens in TV is quite different from reality. |
C.Watching TV makes people more creative. |
D.TV plays an important role in society. |
A.positive | B.casual | C.negative | D.indifferent |
Try it on, virtually (虚拟的).Want to shop online for a new pair of eyeglasses? You don"t need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you"re checking out on a picture of your face.But what if you want to buy something bigger? Thanks to Microsoft Kinect"s motion tracking camera, you can cover clothes on your screen body.You can even choose the background of your virtual fitting room to enrich your shopping experience.
Get a perfect, custom fit.Everyone"s body is shaped differently.To get a perfect fit, you sometimes have to get your clothes changed.But by using 3D scanning technology, all the clothes you buy will fit your body perfectly.Some companies scan your body using High-tech to get the most accurate measurements, so they can make special clothes just for you.
High-tech shopping carts and checkout counters.High-tech shopping carts could, in time, be a common sight in malls and supermarkets.Microsoft Kinect-enabled carts are currently under test.The cart can follow you along the aisles (通道), controlled merely by your movement and your voice.In China, a supermarket chain introduced tablet-equipped carts that guide shoppers around the stores" aisles.
In the United States, several supermarkets use a device called Scan It that gives buyers the freedom to scan purchases on their own while they shop.While it"s great not having to line up at a checkout counter, we wouldn"t mind it if the store used Toshiba"s new Object Recognition Scanner.The machine identifies a product as soon as it"s placed in front of a camera just by its shape and color, even if it has no bar code.
