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 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 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.
小题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

小题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

小题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.

小题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.

There has been a dramatic increase in the number of natural disasters over the past few years, and it is assumed that global warming and climate change could cause even more disasters in the future. Some of the world’s leading cities are facing disasters like floods and heat waves.
London
London’s flood defences are getting older. Since 1982, the Thames Barrier(水闸)has protected the city from the threat of flooding, but it was only designed to last until 2030 and close once every two or three years. About 26 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.
There are 26 underground stations, 400 schools, 16 hospitals, an airport and 80 billion worth of property in London’s flood risk area, so large scale flooding would be disastrous.
Paris
Over a six week period in July and August 2003, more than 1 1,400—mainly elderly people—died in France from dehydration(脱水)and extremely high body temperature in a deadly heat wave. Heat waves of similar intensity(强度)are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?
One solution is to have air-conditioners installed in elderly care homes. But this is considered a short-term solution, as the increase in demand for electricity also increases carbon emissions(排放).
In Paris the local authorities are encouraging architects to design new types of buildings such as the building “Flower Tower,” which uses a covering of bamboo to act as a natural air-conditioner.
Shanghai
Shanghai is the fastest growing city on Earth. It has a population of 18 million and is only 4 meters above sea level. Sea levels are predicted to rise by 20 cm within the next century.
An estimated 250，000 people move to Shanghai every year in search of work, placing extra demands on energy consumption. China relies heavily on coal—fired power stations, but these emissions increase temperatures and, in turn, warmer seas increase the risk of typhoons.
小题1:What problem should be settled now in London?

A．How to protect the city’s property

B．Where to build its flood defences

C．How to use the Thames Barrier to protect the city

D．How to improve the function of the old flood defences

小题2:Which of the following measures can’t solve the heat wave disaster in Paris?

A．Putting up new types of buildings with a covering of bamboo

B．Having air-conditioners installed in elderly care homes

C．Forbidding the city to build“Flower Tower”

D．Encouraging architects to design new types of buildings

小题3:The major threats to Shanghai are ．

A．increasing population and coal-fired power stations

B．rising sea levels and typhoons

C．extremely high temperature and rising sea levels

D．extra demands on energy consumption and typhoons

小题4:The purpose of the passage is ．

A．to tell us how to protect the big cities

B．to give advice on how to defend natural disasters

C．to explain what causes flood and heat waves

D．to warn us of the increasing natural disasters in big cities

小题5:Which of the following would be the best title for the passage?

A．Big Cities Facing Big Disasters

B．Big Disasters in the Future

C．The Increase of Natural Disasters

D．Solutions to Natural Disasters

Educating girls quite possibly gets a higher rate of return than any other deal available in the developing world．Women's education may be unusual field for economists, but increasing women's contribution to development is actually as much an economic as a social project．And economics, with its emphasis on incentives （激励）, provides an explanation for why so many girls lose the chance of education．
Parents in low-income countries don't send their daughters to school because they do not expect them to make an economic contribution to the family: girls grow up only to marry into somebody else's family and bear children．Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school----the prophecy （预言） becomes self-fulfilling, trapping women in a vicious circle （恶性循环）of abandonment．
An educated mother, on the other hand．has greater earning abilities outside the home and faces an entirely different set of choices．She is likely to have fewer but healthier children and can insist on the development of all her children, ensuring that her daughters are given a fair chance．The education of her daughters then makes it much more likely that the next generation of girls, as well as of boys．will be educated and healthy. The vicious circle is thus transformed into a virtuous circle （良性循环）．
Few will argue that educating women has great social benefits．But it has enormous economic advantages as well．Most obviously, there is the direct effect of education on the wages of female workers．Wages rise by 10 to 20 per cent for each additional year of schooling．Such big returns are impressive by the standard of other available deal, but they are just the beginning．Educating women also has a significant impact on health practices， including family planning．
小题1:The author argues that educating girls in developing countries is _______．

A．expensive	B．troublesome
C．rewarding	D．labor-saving

小题2:What does the author say about women's education?

A．It has developed the interest of a growing number of economists

B．It is in the first place in many developing countries

C．It deserves greater attention than other social project

D．It will get greater returns than other known deal

小题3:The passage mainly discusses ______．

A．unequal treatment of boys and girls in developing countries

B．the economic and social benefits of educating women

C．the major contributions of educated women to society

D．the potential earning power of well-educated women

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!
The Biggest and the Smallest Frogs
Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.
The Best Jumpers
Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.
The Cryogenic Animal
Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.
小题1:The earliest frogs lived about ________ million years ago.

A．20

B．30

C．50

D．190

小题2:The Gold Frog is one of the ________ frogs on the earth.

A．smallest

C．strongest

D．weakest

小题3:________ can jump over 2m.

A．The Goliath Frog	B．The Common Wood Frog
C．The Poison Frog	D．The Australian Rocket Frog

Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe. Geographers predict that within the next eighty years, current world climate zones could shift and some could completely disappear. Polar regions will get colder while tropical regions will get even hotter, forcing animals to migrate (迁徙) north.
Climate changes like these could lead to the spread of diseases. Tropical storms and hurricanes will not only increase but may also become more intense. If the changes come too quickly, animal and plant species may not be able to adapt fast enough and could disappear.
According to Science Daily, a new study predicts that by the year 2100, many of today’s familiar climates will be replaced by climates unknown in today’s world. It is urgent that we reduce the risks of these far-reaching consequences for the whole world. The planet itself has been showing signs of change. In 2004, a serious tsunami created by a major earthquake killed thousands in Sumatra and in 2008, thousands died in China because of another severe earthquake. Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.
Within just the last few months, new reports from around the world have been coming in and most agree that our climate situation is much worse than previously thought. At this point, it doesn’t matter what is causing it, but rather, what can be done about it. What’s more, our world is getting more and more unstable every year. There is war and threat of war everywhere. Natural disasters are becoming more frequent and serious.
However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this. No one knows anything for sure at this point because there is simply not enough data.
小题1: Which of the following would be the best title for the Passage ?

A．Ways to protect our planet.	B．Solutions to climate change.
C．Be prepared for climate change.	D．Climate change and its effects.

小题2: What is the author’s purpose in using the examples of earthquakes?

A．To show the damage earthquakes caused.

B．To remind people to prevent future earthquakes.

C．To show major changes are taking place on the planet.

D．To tell us more earthquakes will happen in the future.

小题3: What does the underlined word “devastated” in Paragraph 3 mean?

A．Separated.

B．Destroyed.

C．Removed.

D．Affected.

小题4: What can be inferred from the Passage?

A．Animals and plants won’t die out as long as climate changes slowly.

B．There’s enough data for us to predict the future of climate change.

C．The world is getting more unstable because of animal migration.

D．The earth is not the only planet that is experiencing climate change.

Poor Oral Health Leads to Social and Emotional Problems
A new report says nearly four-billion people have major tooth decay, or cavities. That number represents more than half of the world's population. Health officials are warning that failure to repair cavities can lead to social and emotional problems.
Wagner Marcenes is with the Institute of Dentistry at Queen Mary, University of London. He led a team of researchers as part of the Global Burden of Disease 2010 study. About 500 researchers attempt to collect and examine studies about all major diseases. They used the information to estimate rates of the infection.
The report says untreated tooth decay is the most common of all 291 major diseases and injuries. Professor Marcenes says cavities or holes in permanent teeth are also known as caries.
"Caries is a chronic disease that shares the same risk factors as cancer, cardiovascular disease. What we're having now is an increase in disease from highly developed countries happening in sub-Saharan Africa and probably it will be in other areas of Africa, too."
He says an increase in tooth decay in Africa could be a result of developing countries becoming more like Western nations.
"It is likely to be related to a change in diet. Our industrialized diet leads to chronic disease, which includes caries. And that may be the main explanation."
Western diets are rich in sugar, a leading cause of health problems in the mouth. Wagner Marcenes says oral health problems can have a major effect on a person's quality of life. First, cavities make eating difficult. Second, people may change what they eat. They may eat softer foods that are not hard to chew. However, softer foods are often fattier foods.
But professor Marcenes says the biggest issue in tooth decay is both social and mental. He says the researchers found strong evidence that the mouth has a big influence on socialization. He says many people want to hide bad teeth. They smile less and communicate less.
Wagner Marcenes is calling for an "urgent, organized, social response" to the widespread lack of oral health. He believes in a natural method to fight tooth decay by having a healthier diet. He is also calling for the development of new and less costly dental materials and treatments.
小题1:From the passage, we know that Wagner Marcenes ______.

A．works as the leader of the Institute of Dentistry at Queen Mary, University of London.

B．and his researchers accumulate some studies to find out some ways to cure all major disease.

C．is in charge of the activity to estimate the infection rate with the collected and examined studies about all major studies.

D．thinks that the most serious problem caused by tooth decay is cancer that will last for a long time.

小题2:Caries is a disease that ______.

A．is listed in the most common of all 291 major diseases and injuries which will last for a long time..

B．is closely related to industrialized diet which calls for people to eat slowly.

C．increases in Africa now because developing countries are becoming developed countries.

D．will cause phychological disorder which will affect people’s communication.

小题3:The writer wrote this passage in order to ______.

A．arouse people’s concern about caries and take measures to deal with it.

B．tell the result of the Global Burden of Disease 2010 study.

C．warn people in Africa to adjust their diet to prevent caries.

D．tell doctors that caries affects a person’s quality of life.

小题4:What is the writer’s attitude towards tooth decay?

A．indifferent

B．concerned

C．angry

D．negative

In July 1994 Jupiter, the largest planet in our solar system, was struck by 21 pieces of a comet (彗星). When the fragments (碎片) landed in the southern part of the giant planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?
　The year is 2094. It has been announced that a comet is heading towards the Earth. Most of it will miss our planet, but two fragments will probably hit the southern part of the Earth. The news has caused panic.
　On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the speed of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and millions of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.
　Millions of people are already dead in the southern part of the Earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosions. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.
　Could it really happen? In fact, it has already happened more than once in the history of the Earth. The dinosaurs were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?
小题1:55.Which of the following is NOT TRUE according to the author's description of the disaster in 2094?

A．The whole world becomes extremely cold

B．All the coastal cities in Africa are destroyed

C．The visit of the comet results in wars

D．The whole mankind becomes extinct

小题2:56.Why does the author mention dinosaurs at the end of the passage?

A．Because they could only live in the warm climate

B．Because their extinction indicates future disasters

C．Because they once dominated the earth

D．Because dinosaurs and humans never live in the same age

小题3:57.In writing the passage, the author intends to ______.

A．give an accurate description of the possible disaster in the future

B．prove that humans will sooner or later be destroyed

C．warn of a possible disaster in the future

D．tell the historical development of the Earth

小题4:58.It can be concluded that the passage is most probably part of a(n) ______.

One might expect that the ever-growing demands of the tourist trade would bring nothing but good for the countries that receive the holiday-makers. Indeed, a rosy picture is painted for the long-term future of the holiday industry. Every month sees the building of a new hotel somewhere, and every month another rock-bound Pacific island is advertised as the 'last paradise(天堂) on earth'.
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of sea-side holidays, over-crowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holiday-makers traveling through the forest land. Ancient tacks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The one-time farmer is now the servant of some multi-national organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning world-wide tourism can preserve the market for these companies. If not, in a few years’ time the very things that attract tourists now may well have been destroyed.
小题1:What does the author indicate in the last sentence of Paragraph 1?

A．The Pacific Island is a paradise.	B．The Pacific Island is worth visiting.
C．The advertisement is not convincing.	D．The advertisement is not impressive

小题2:The example of Nepal is used to suggest _________.

A．its natural resources are untouched

B．its forests are exploited for farmland

C．it develops well in health and education

D．it suffers from the heavy flow of tourists.

小题3:What can we learn about the farmers from Paragraph 4?

A．They are happy to work their own lands.

B．They have to please the tourists for a living.

C．They have to struggle for their independence.

D．They are proud of working in multi-national organizations.

小题4:Which of the following determines the future of tourism?

A．The number of tourists	B．The improvement of services.
C．The promotion of new products.	D．The management of tourism

小题5:The author’s attitude towards the development of the tourist industry is __________.

A．optimistic

B．doubtful

C．objective

D．negative
