Pupils remember more and behave better when 3D images areused in lessons，research suggests.They are quicker to learn andabsorb 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(模仿動(dòng)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 technology­90 percent of those in the study had seen a 3D film.Schools would need 3D­enabled projectors(投影儀)，laptops with good picture capabilities,3D software and glasses for children to introduce animations(動(dòng)作) into classrooms.
But Danny Nicholson，an educationist，said the technology would be impractical to use inschools 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(小玩意兒)．There are a few cases where a true3D image might help，but most of the time，good 2D models that can be moved would be just aseffective.”
In the US，one school district in Colorado is already in the process of having 1,000 3Dprojectors 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.
小題1:What is the main idea of the first three paragraphs?
A．There are slight differences between 3D and 2D images.
B．Pupils perform better when 3D images are used in classes.
C．Schools have difficulties in making full use of 3D technology.
D．3D technology is always more effective than 2D technology.
小題2:Danny Nicholson holds the view that 3D ________.
A．is of no help in classes
B．has a bright future in classes
C．is more practical than 2D models

小題3:D
小題4:A

文章大意：本文講述了3D影響在教學(xué)中的應(yīng)用，雖然有人提出反對(duì)意見，但研究表明了3D用于教學(xué)的有效性，提高了教學(xué)效果：提高了學(xué)生的記憶效果、理解能力和接受能力，而且在美國的科羅拉多州的一個(gè)學(xué)校已經(jīng)投入使用。
小題1:B　主旨大意題。前三段的主題句是第一段第一句話，所以B項(xiàng)正確。
小題2:D　細(xì)節(jié)理解題。由倒數(shù)第二段的But可知，Danny Nicholson 持相反的觀點(diǎn)；再根據(jù)Danny Nicholson 的話“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)．”可知，Danny Nicholson認(rèn)為，3D是不切實(shí)際的，因?yàn)楹芏鄬W(xué)校負(fù)擔(dān)不起。
小題3:D　推理判斷題。根據(jù)最后一段第一句話“In Colorado, the US, one school district is already in the process of having 1,000 3D projectors fixed in classrooms”，得出在科羅拉多3D課堂會(huì)在一個(gè)學(xué)校開展，D項(xiàng)正確。
小題4:A　猜測(cè)詞義題。由劃線詞后的“and reported a general increase in their interest in science”可推知，觀看3D課堂的學(xué)生會(huì)更加注意力集中，而且會(huì)對(duì)科學(xué)越來越感興趣。所以劃線詞應(yīng)為“集中注意力的”。

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid --- we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard（蜥蜴）native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we’ll need huge feet that we could bring up to our ears in order to create adequate “hitting.”
But fortunately there is an alternative: cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now if the surface of the water is hit hard enough, particles（粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink --- and take a shower afterward!
小題1:Walking on water hasn’t become a reality mainly because humans _______.
A．a(chǎn)re not interested in it
B．have biological limitations
C．have not invented proper tools
D．a(chǎn)re afraid to make an attempt
小題2:What do we know about Basilicus basilicas from the passage?
A．It is light enough to walk on water.
B．Its huge feet enable it to stay above water.
C．It can run across water at a certain speed
D．Its unique skin keeps it from getting wet in water
小題3:What is the function of the cornflour according to the passage?
A．To create a thick liquid.
B．To turn the water into solid.
C．To help the liquid behave normally.
D．To enable the water to move rapidly.
小題4:What is the author’s attitude toward the idea of human’s walking on water?
A．It is risky but beneficial.
B．It is interesting and worth trying
C．It is crazy and cannot become a reality
D．It is impractical; though theoretically possible

“I can’t concentrate.” “My mind wanders when I try to study.” Lack of concentration is one of the most common complaints heard at school.
We all have the ability to concentrate. Think of the times when you were attracted to a super novel or the times when you were playing your guitar or piano. But at other times your mind races from one thing to another. Here are some tips.
Rest from time to time. Remember to take short breaks. Lectures are usually 50 minutes long, and that’s about the length of time most people can direct their attention to one task. But that’s just an average. Your concentration time might be shorter (20-35 minutes) or longer (perhaps 90 minutes).When you take a break, you get more oxygen to your brain! When we sit for long periods, blood tends to be pooled in our lower body and legs. Get up and walk around the room for a couple of minutes. As a result, more oxygen is carried to the brain and you can concentrate better.
_______________If you study one subject for a long time, you may find it hard to concentrate. Many students improve their concentration by changing one subject to another every one to two hours. In this way you can pay more attention to something that’s different.
Reward yourself. Give yourself a reward when you’ve completed a task. The task might be small, such as staying with a difficult paper until you’ve finished. But giving yourself a reward can help you be more interested in doing other tasks.
Increase your activity level. Your concentration wanders more easily if you just read an article straight through. Instead, take the heading for each part and turn it into a question. For this part, that would be, “How can I increase my activity level while studying?” Then study that part to answer that question. Do this routinely. The questions give us a focus for each part and increase our involvement(參與).
小題1:According to Paragraph 3, what’s the purpose of walking around?
A．To help us stay fit.
B．To benefit our lower body.
C．To provide the brain with more oxygen.
D．To increase our concentration time to 90 minutes.
小題2:What’s the best title for Paragraph 4?
A．Study for one hour each time.
B．Do something difficult.
C．Study in different ways.
D．Change subjects.
小題3:In the last paragraph, the writer suggests that______.
A．we just read the heading of some articles
B．we do our best to read an article straight through
C．we ask ourselves questions about what we are reading
D．we ask other people questions about the article we are reading
小題4:The writer wrote the passage to______.
A．encourage us to try to concentrate
B．teach us how to concentrate while studying
C．give us the reasons for a lack of concentration
D．list the benefits we can get from concentration

To most of us，school means classes，teachers，schedules，grades，and tests.But for the children at Sudbury Valley School in Massachusetts，school is very different.
Firstly，there are no lessons.All the children，aged between 4 and 19，do whatever they want.There are no teachers—only “staff members”．The idea behind this is that you do not need to make children learn，because children want to learn anyway.“You do not need to say to a three year­old，‘Go explore your environment.'You can't stop them！” says Daniel Greenberg，a founder of the school.“But if you make children do what you want all day，they will lose all taste for learning.”
At Sudbury Valley School，you will permit children to talk，read，paint，cook，work on computers，study French，play the piano，climb trees or just run around.Two boys spent three years just fishing!
The other way that Sudbury Valley School is different is that the children can decide the rules.Every week，there is a school meeting where both children and staff have one vote each—even the four­year­olds.They decide the school rules，how to spend the school budget，and even which staff they want and do not want any more.
When the school first opened in 1968，people said it would never work.But today，the school has 200 students，and 80%of its students go on to college. Even the two boys who went fishing all the time have successful careers today.One of them is a musician and the other is a computer scientist.
小題1:What is the main topic of the article?
A．An unusual school.B．Children's hobbies.
C．A school without rules.D．Education in the US.
小題2:What does the school believe?
A．Teachers cannot teach children Well.
B．Children learn best when they do what they want to do.
C．Learning is for adults—children should only play.
D．Children should only learn about one thing at a time.
小題3:What does Daniel Greenberg say about three­year­olds?
A．They love learning.
B．They are very naughty.
C．They want to be outside all the time.
D．They are too young to learn anything.
小題4:Who has the most power in the school meetings?
A．The older children have more power than the younger children.
B．A child has more power than an adult.
C．The younger children have more power than the older children.
D．Everybody has equal power.

In her new book, “The Smartest Kids in the World”， Amanda Ripley, an investigative journalist, tells the story of Tom, a high­school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Wroclaw, Poland. Poland is a surprising educational success story: in the past decade, the country raised students' test scores from significantly below average to well above it. Polish kids have now outscored American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Wroclaw is that the latter has no football team or teams of any kind.
That American high schools spend more time and money on sports than on math is an old complaint. In December, when the latest Program for International Student Assessment (PISA) results are announced, it's safe to predict that American high­school students will once again show their limited skills in math and reading, outscored not just by students in Poland but also by students in places like China, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D．C., which costs thirty thousand dollars a year. The tour leader ­ a mother with three children in the school ­ was asked about the school's flaws (瑕疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really？” one of them asked worriedly, “What do you mean？”
One of the ironies of the situation is that sports show what is possible. American kids' performance on the field shows just how well they can do when expectations are high. It's too bad that their_test_scores_show_the_same_thing._
小題1:Tom decides to spend his senior year in Poland because ________.
A．he intends to improve his scores
B．Polish kids are better at learning
C．sports are not supported at schools in Gettysburg
D．he wants to be the smartest kid in the world
小題2:According to Paragraph 2, we know that ________.
A．PISA plays a very important role in America
B．little time is spent on sports in Japanese schools
C．American students do better in both math and sports
D．too much importance is placed on sports in America
小題3:The underlined sentence in the last paragraph means ________.
A．low expectations result in American students' poor PISA performance
B．high expectations push up American students' academic performance
C．American students' academic performance worries their parents a lot
D．lacking practice contributes to American students' average performance
小題4:The purpose of this article is to ________.
A．compare Polish schools with those in America
B．call on American schools to learn from the Polish model
C．draw public attention to a weakness in American school tradition
D．explain what is wrong with American schools and provide solutions

Have you seen a yellow-and-black salamander (火蜥蜴)? How about a scarlet frog? Scientists haven’t spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct?
Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads(蟾蜍), and salamanders are amphibians.
The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They’re also looking for species in Africa, Asia and Australia.
Scientists are hopeful that they’ll find the amphibians—and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live.
“If researchers can find the missing creatures, they might be able to figure out how to save them,” explains expert Robin Moore. He began searching for the amphibians earlier this month.
“This search will tell us a lot about how amphibians are doing,” Moore told WR News. “I don’t know what we will find, but that makes the search even more exciting.”
Lost in the Wild
Scientists’ hunt for missing amphibians is under way. Read about some of the species they hope to find.
Turkestanian salamander
This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since.
Gastric brooding frog
Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss.
Rio Pescado stubfoot toad
Last sighting: 1995, in South America
Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease.
小題1: Which of the following animals hasn’t been seen for over a century?
A．Rio Pescado stubfoot toad.
B．Gastric brooding frog.
C．Turkestanian salamander.
D．Scarlet frog.
小題2:It can be learned from the passage that _____.
A．the scarlet frog used to live in Africa
B．researchers have no way to save amphibians
C．the scientists will search 14 countries at most
D．Robin Moore has begun his search for amphibians
小題3: Why do the scientists want to find the missing amphibians?

At first sight the planet Mars(火星)does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles(161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes(火山); the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists.

Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun’s heat in the planet’s atmosphere. With warmth, water and carbon dioxide, simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between
100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.

Reseachers at the University of Kansas say that people can accurately judge 90 percent of a stranger's personality simply by looking at the person’s shoes．“Shoes convey useful information about their wearers，’’the authors wrote in the new study published in the Journal of Research in Personality．
Lead researcher Omri Gillath said the judgments were based on the style，cost，color and condition of someone’s shoes．In the study，63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study’s participants.Volunteers in the study were photographed in their most commonly worn shoes，and then filled out a personality questionnaire．
Some of the results were expected：People with higher incomes most commonly wore expensive shoes，and flashier shoes were typically worn by outgoing people．However，some of the more specific results are strange enough．For example，“practical and functional’’shoes were generally worn by more“pleasant"people，while ankle boots were more linked with ‘‘a(chǎn)ggressive’’personalities．The strangest of all may be that those who wore‘‘uncomfortable looking” shoes tend to have “calm” personalities. And if you have several pairs of new shoes or take extreme care of them，you may suffer from“attachment anxiety"，spending lots of time worrying about what other people think of your appearance．There was even a political calculation in the mix with more liberal(主張變革的)types wearing“shabbier and less expensive” shoes．
The researchers noted that some people will choose shoe styles to mask their actual personalities，but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities．
小題1:What does this text mainly tell us?
A．People’s personalities call be judged by their shoes．
B．Shoes convey false information about the wearer．
C．People know little about their personalities．
D．Shoes Call hide people’s real personalities．
小題2:The participants were asked to       
A．look at pictures of different shoes
B．provide pictures of their shoes
C．hand in their commonly worn shoes
D．design a personality questionnaire
小題3:Which of the results is beyond people’s expectation?
A．Pleasant people like wearing uncomfortable shoes．
B．Wealthy people often wear expensive shoes．
C．Flahshier shoes are typically worn by outgoing people．
D．Aggressive people are likely to weal"ankle boots．
小題4:People suffering from“attachment anxiety” tend to       
A．become a political leader
B．have a calm character
C．worry about their appearance
D．wear strange shoes
小題5:The author wrote the text in order to      
A．teach how to choose shoes
B．describe different personalities

Dreams can be familiar and strange, fantastical or boring, but some dreams might be connected to the mental processes that help us learn. In a recent study, scientists found a connection between nap-time dreams and better memory in people who were learning a new skill.
In the study,99 college students between the ages of 18 and 30 each spent an hour on a compute, trying to get through a virtual maze（迷宮）.The maze was different place each time they tired—making it even more difficult. They were also told to find a particular picture of a tree and remember where it was.
For the first 90 minutes of a five-hour break, half of the participants stayed awake and an half were told to take a short nap .Participants who stayed awake were asked to describe their thoughts. Participants who took a nap were asked about their dreams before sleep and after sleep—and they were awakened within a minute of sleep to describe their dreams.
Stickgold, a neuroscientist（神經(jīng)科學(xué)家）,wanted to know what people were dreaming about when their eyes weren＇t moving during sleep.
Four of the 50 people who slept said their dreams were connected to the maze. Some dreamed about the music that had been playing when they were working ; others said they dreamed about seeing people in the maze. When these four people tried the computer maze again, they were able to find the tree faster than before their naps.
Stickgold suggests the dream itself doesn‘t  help a person learn—it＇s the other way around.He suspects that the dream was caused by the brain processes associated with learning.
All four of the people who dreamed about the task had done poorly the first time, which makes Stickgold wonder if the dreams show up when a person finds a new task particularly difficult. People who had other dreams, or people who didn＇t take a nap, didn＇t show the same improvement.
小題1:Before having a short nap, participants of the experiment were asked to       .
A．stay in a different place in the maze
B．design a virtual maze which is difficult to get through
C．experience the experiment and try to remember something
D．get through a virtual maze on a computer from the same place
小題2:What can we learn from the text?
A．Participants who took a nap were required to express their thoughts.
B．Some dreams may encourage people to invent something new.
C．Participants who dreamed about films could finish the task more easily.
D．Participants whose dreams had something to do with the maze could find the tree faster.
小題3:According to Stickgold,       .
A．every person may dream about what they learned
B．people＇s brain processes may still be connected with their learning in their dreams
C．once people＇s eyes stop moving, they are sure to dream about something
D．no matter how fantastical or boring, dreams are connected with people＇s life
小題4:What is the best title for this text?
A．Dreams Are StrangeB．Not All Dreams Are True
C．Dreaming Makes PerfectD．Stickgold, a Dream Expert
