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．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． |
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 |
| D．may not be affordable for schools |
What can we learn from the last paragraph?
| A．3D technology will replace 2D models in the future． |
| B．Many pupils are now more Interested In science than before． |
| C．Teachers will use the 3D technology through specific training． |
| D．3D will soon be put into use in one school district in Colorado． |
The underlined word “engrossed” in the last paragraph means_____.
| A．absorbed | B．annoyed |
| C．relaxed | D．confused |
In the decade（十年）of the 1970s, the United Nations organized several important meetings on the human environment to study a very serious problem．We humans are destroying the world around us．We must learn to protect them, or life will be very bad for our children and grandchildren．
There are several major aspects to this problem．
Population
Most problems of the environment come from population growth．In 1700 there were 635 million people in the world; in 1900 there were 1．6 billion; in 1950, 2．5 billion; and in 1980, 4．4 billion．In the year 2010 there will be 7．3 billion．More people need more water, more food, more wood, and more petroleum．
Distribution
Scientists say there is enough water in the world for everyone, but some countries have a lot of water and some have only a little．Some areas get all rain during one season．The rest of the year is dry．
Petroleum
We are using up the world’s petroleum．We use it in our cars and to heat our buildings in winter．Farmers use petrochemicals to make the soil rich．They use them to kill insects on those plants．These chemicals go into rivers and lakes and kill the fish there．Thousands of people also die from these chemicals every year．Chemicals also go into the air and pollute it．Winds carry this polluted air to other countries and other countries．
Poverty
Poor farmers use the same land over and over．The land needs a rest so it will be better next year．However, the farmer must have food every year．Poor people cut down trees for firewood．In some areas when the trees are gone, the land becomes desert．However, people need wood to cook their food now．Poor people cannot save the environment for the future．
We now have the information and the ability to solve these huge problems．However, this is not a problem for one country or one area of the world．It is a problem for all humans．The people and the nation of the world must work together to protect the world’s resources．No one controls the future, but we all help make it．According to the passage, our world is being destroyed mainly because ______．
| A．pollution is getting worse and worse |
| B．population are increasing greatly |
| C．we humans are using up all of our natural resources |
| D．distribution is not reasonable． |
Good distribution means ________．
| A．having things in the right place at the right time． |
| B．cutting down forests and selling them to other countries． |
| C．building water systems to carry water to farms． |
| D．conserving our natural resources |
The best title of the passage should be ________
| A．The World Being Destroyed |
| B．A Serious Problem We Should Pay Attention to |
| C．Aspects That Destroyed Our World |
| D．Conserving the World’s Natural Resources |
Love, success, happiness, family and freedom----how important are these values to you? Here is one interview which explores the fundamental questions in life．

Misbah, 27 years old．I was born in a war-torn area．Right now I’m a web designer．
Q: What are your great memories?

Every day we experience one of the wonders of the world around us without even realizing it．It is not the amazing complexity of television, nor the impressive technology of transport．The universal wonder we share and experience is our ability to make noise without mouths, and so transmit ideas and thoughts to each other’s minds．This ability comes so naturally that we tend to forget what a miracle （奇迹） it is．
Obviously, the ability to talk is something that marks humans off from animal．Of course, some animals have powers just as amazing, Birds can fly thousands miles by observing positions of the stars in the sky in relation to the time of day and year．In Nature’s talent show, humans are a species of animal that have developed their own special act．If we reduce it to basic terms, it’s an ability for communicating information to others, by varying sounds we make as we breathe out．
Not that we don’t have other powers of communication．Our facial expressions convey our emotions, such as anger, or joy, or disappointment．The way we hold our heads can indicate to others whether we are happy or sad．This is so-called “body language”．Bristling （直立的） fur is an unmistakable warning of attack among many animals．Similarly, the bowed head or drooping tail shows a readiness to take second place in any animal gathering．
Such a means of communication is a basic mechanism that animals, including human beings, instinctively acquire and display．Is the ability to speak just another sort of instinct? If so, how did human beings acquire this amazing skills ? Biologist can readily indicate that particular area of our brain where speech mechanisms function, but this doesn’t tell us how that part of our bodies originated in our biological history．According to the passage, the wonder we take for granted is．
| A．our ability to use language |
| B．the miracle of technology |
| C．the amazing power of nature |
| D．our ability to make noises with mouth |
What feature of “body language” mentioned in the passage is common to both human an animals?
| A．Lifting heads when sad． |
| B．Keeping long faces when angry． |
| C．Bristling hair when ready to attack． |
| D．Bowing heads when willing to obey． |
What can be inferred from Paragraph 3?
| A．Body language is unique to humans． |
| B．Humans are no different from animals to some degree． |
| C．Humans have other powers of communication． |
| D．Animals express emotions just as humans do． |
This passage is mainly about．
| A．the development of body language． |
| B．the special role humans play in nature |
| C．the power to convey information to others |
| D．the difference between humans and animals in language use |
Many people take it for granted that black is a color 
of bad things while white should always mean something good．This may be because, in their opinion, black is related to darkness and white to purity（纯洁）．
However, that is not always the case．Did you know that the same colour may mean differently in different places of the world?
In the English-speaking world, black is the colour of mourning（哀悼）．People wear black clothes at the funeral．Red is concerned with danger or bloodshed (流血)．Yellow is the word for fear．If you are afraid, you are yellow．Yet none of these sayings is true outside the English-speaking world．In China and Korea white is the colour of mourning．In Russia, China and some other countries, red stands for beauty, life and excellence．In Italy and Germany, you are yellow with anger, not with fear．
Even within the English-speaking area it is not difficult to find colour contradictions (矛盾)．A redcap in the United States is a porter in a railway station．In Britain, however, a redcap is a military policeman．Both names are logical because both men wear red caps．Similarly, the British term for an American white collar worker is sometimes called a black-coated worker．
One does not have to cross an area to find color differences．Would you rather be red-blooded? If we go back to the origin, we find that both terms are logical as both names suggest．The expression “blueblood” comes from Spain, where some noble（贵族）families proudly said that they had “blue blood”．But then why “blue” blood? Because they were fair-skinned, and it is only natural that their blood vessels (血管) stood out appearing blue．Yellow is concerned with anger in ______.
| A．Russia | B．Britain | C．Germany | D．China |
Both Britain and America would probably agree that ______.
| A．black is the color of mourning | B．a black-coated worker is employed in an office |
| C．red stands for beauty and excellence | D．a redcap is a porter in a station |
The best title for this passage is ______.
| A．The Origin of Blue Blood | B．The Development of the Use of Colors |
| C．Colors that Carry Bad Meanings | D．The Meaning Concerned With Certain Colors |
When some Spanish called themselves “blueblood”, they actually meant ______.
| A．they had heart trouble and their faces looked blue | B．they came from a noble family |
| C．they had blue blood in their vessels | D．they were fair-skinned |
