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 studied the effectiveness of 3D content in 15 schools across seven countries. In each school, one class studied science in 2D classes and another did the same lesson using 3D resources. Pupils in 3D classes could remember more than those in 2D classes after four weeks, improving test scores by an average of 17 percent compared with 8 percent for 2D lessons.
The researchers commented that the pupils in the 3D groups had deeper understanding, increased attention span, more motivation and higher engrossment in the lessons.
One teacher in the study said, “ In class with 3D you have the ‘wow’ effect. The pupils are too interested to be disruptive(制造混乱的). They get involved and forget to be naughty.” Another said, “The class certainly pay more attention to the learning in the 3D classes. They are more focused. That is important in this class --- eight out of the 26 pupils in this class have attention problems, so I am thrilled with the impact of 3D. They are really attentive.” The study also found that teachers could use the 3D animations without specific training. Schools would need 3D-enabled projectors(放映机), laptops with good graphic capabilities, 3D software and glasses for children to introduce animations into classrooms.
But Danny Nicholson, from the Association of Science Education, 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 --- and I’m speaking as a fan of interactive whiteboards and projectors as a technology in the classroom --- 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 a lot of the time, good 2D models that can be moved, would be just as effective.”
In Colorado, the US, one school district is already in the process of having 1,000 3D projectors installed in classrooms. And the University of California, which carries out scientific research into the Lake Tahoe 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.What method did Professor Bamford use to prove the advantages of 3D lessons?

Barack Obama has really gone wild. The US president has taken part in the survival television show Running Wild With Bear Grylls, which will air on NBC later this year. In the show, Obama goes on an adventure with host Bear Grylls, learning how to survive in the Alaskan wilderness.
Edward Michael “Bear” Grylls, 41, has become known around the world as one of the most famous outdoor adventurers. The Briton has appeared on a number of wilderness survival shows in which he has climbed, sailed, and eaten bugs or cow tongue.
Obama doesn’t have to eat bugs or cow tongue on his adventure with Grylls. But he does have to eat leftovers - a bloody salmon (三文鱼). It was partly enjoyed by a bear that left some meat behind.
Although he is far from the White House kitchen, Obama seems to enjoy the outdoors. “As president, I am in what’s called the bubble（保护膜）, and the Secret Service makes sure that I’m always out of danger ... but I sometimes want to get out,” he said in a video.
However, Obama’s appearance on the show isn’t just for fun. He took part to raise awareness of the effect global warming has had on the US’s largest state, Alaska.

When I was having a walk through the park today, I met a friend I hadn’t seen for ages. She stared at me curiously. “You have kept this umbrella for years; it's old and out of date. I wonder why you keep it and take it wherever you go.” I smiled, “it means a great deal to me.” I simply gave her my shortest answer. Honestly speaking, I, either, could not understand the reason why I kept it.
Then all of a sudden, fallen leaves darkened my eyes with a strong wind. I grabbed the umbrella instinctively. The rain poured down. Thanks to my umbrella, I didn’t get wet at all.
“Why have I kept it for so long?” I asked myself, staring at my umbrella. I couldn’t remember when and where I bought it, for I’m always tired and lazy to answer questions. It could protect me from the heavy rain, I told myself eventually. Looking at the people rushing through the street, I felt safe. This might be another reason.
It is always so. We know a thunderstorm comes unexpectedly and goes without a warning. The sky cleared up. The sun shone brightly. Just as usual, I seized the umbrella with my left hand. Still there’s water dropping down. I walked among the noisy crowd and listened to what they were murmuring in their heart. “Today I will ask for a rise, or I'll leave this company.” Good luck to you, I smiled to him. “I’ll manage to make you live forever.” A little boy held a pet dog close to him. “She’ll be all right, because she is blessed.” I heard angels singing in this city.
The moment my fingertips touched the umbrella, I felt it’s dry, and it’s warm. Soon it became hot. I held it up to avoid harmful sunshine. Do I need a reason to explain why? Maybe I should think about it. I need my umbrella when it is sunny as well as when it is rainy.Which of the following words best describes the author?

Many gardeners believe that “talking” to their plants helps them grow---it turns out that they may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language.
For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase(虫荧光素酶), which is what makes fireflies(萤火虫) glow in the dark.
When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”.
While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators(捕食者) like caterpillars(毛虫) away.
What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other.
However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot!What’s the best title of the passage?
| A． Plants Can Send Some Gas |

Why are so many people afraid to fail? Quite simply because we forget that failure is part of the human life and that every person has the right to fail. Every person is able to fight failure and finally succeed.
Most parents work hard at preventing failure or protecting their children from the knowledge that they have failed. One way is to lower standards(标准). When a child finishes making a table, the mother describes it as “perfect” even though it doesn’t stand still. Another way is to blame others. If John fails in science, his teacher is unfair or stupid.
There’s a problem with the two ways. It makes a child unprepared for life in the real world. Young children need to learn that no one can be best at everything, no one can win all the time, and that it’s possible to enjoy a game even when you don’t win. A child often feels terrible, of course, when he is not invited to a birthday party, or is not chosen into a football team. But parents should not say “It doesn’t matter.” quickly. The young should be allowed to experience failure and be helped to come out of it.
Failure never gives people pleasure. It hurts both adults and children. But it can be really good to your life when you learn to use it. You must learn to ask “Why did I fail?” Don’t blame anyone else. Ask yourself what you did wrong and how you can improve. If someone else can help, don’t be shy about asking them. Success just repeats what has been done. It is not as good a teacher as failure. You can learn how to give a good party from an unsuccessful one. How do most parents prevent their children from failure?
| A． They give them some presents. |
| B． They don’t tell them that they have failed. |
| C． They don’t blame others. |
| D． They help them to come out of failure. |
Which of the following does a person need to learn when he fails?
| A． It’s impossible to enjoy a game if he misses it. |
| B． He is the worst of all. |
| C． It’s natural not to win a game and no one can win all the time. |
| D． His teammates are not good enough. |
Which would be the best title for the passage?
| A． Learning from Failure |
| B． Ways of Preventing Failure |
| C． Reasons of Failure |
| D． Getting Pleasure from Failure |
Now many young people are traveling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.
Kristina Wegscheider from California first traveled alone when she was at college and believes that it is something everyone should do at least once in their life. “It opens up your mind to new things and pushes you out of your comfort zone.” Wegscheider has visited 46 countries covering all seven continents.
In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can make it on their own.
Chris Richardson decided to leave his sales job in Australia to go traveling last year. He set up a website, The Aussie Nomad, to document his adventures. He says he wished he had traveled alone earlier. “The people you meet, the places you visit, or the things you do, everything is up to you and it forces you to grow as a person,” said the 30-year-old man.
Richardson describes traveling alone like “a shot in the arm”, which “makes you a more confident person that is ready to deal with anything”. He said, “The feeling of having overcome something on my own is a major part of what drives me each day when I’m dealing with a difficult task. I walk around with my head up because I know deep down inside that nothing is impossible if you try.”
The great 19thcentury explorer John Muir once said, “Only by going alone in silence can one truly get into the heart of the wilderness.”Which of the following will Kristina Wegscheider agree with?
| A． Traveling alone is a necessary experience for everyone. |
| B． It is more meaningful to travel in foreign countries. |
| C． It is comfortable to travel around without a friend. |
| D． Traveling abroad helps people to find new things. |
Traveling alone is challenging because ________.
| A． you have to make things on your own |
| B． it is hard for you to prove yourself to others |
| C． you can only depend on yourself whatever happens |
| D． it will finally build your character |
What can we infer about Chris Richardson?
| A． He started traveling alone at an early age. |
| B． He was once shot in the arm. |
| C． He used to work as a salesman. |
| D． His website inspires others a lot. |
What is the best title for the passage?
| A． Travel Abroad | B． Travel Alone |
| C． Travel Light | D． Travel Wide and Far |
