Culture helps human societies survive in changing natural environment£®For example, the end of the last Ice Age, beginning about 15,000 years ago, brought a big challenge to which humans had to adapt£®Before this time, large parts of the northern hemisphere were covered in great sheets of ice that contained much of the earth' s water£®In North America, large animals that wandered the vast tundra £¨±ùÔ£© provided people with food and materials for clothing and simple shelters£®When the earth became warm, large Ice Age animals disappeared, and many land areas were covered by rising sea levels from melting ice£®But people survived, they developed new technologies and learned how to survive on new plant and animal species£® Finally some people settled into permanent villages, durable houses and farms£®
Cultural adaptation has made humans one of the most successful species on the planet£® Through history, major developments in technology, medicine, and nutrition have allowed people to reproduce and survive in ever-increasing numbers£®The global population has risen from 8 million during the Ice Age to about 6 billion today£®

This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again.
It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic(µØÐÎѧµÄ) factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions(ÅÅ·Å). But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country's power plants are located in the eastern region and China's coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world's total coal consumption. And with coal occupying nearly 70 percent of the country's primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation's overall air pollution problem.
In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on.
However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier.
This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority(ÓÅÏÈȨ)given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity(ÄÜÁ¦) fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation.
Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth.

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without many living things.
Pollution in water is not simply a matter of ¡°poisons¡± killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms (ÉúÎïÌå) to be affected are either plants or plankton (¸¡ÓÎÉúÎï). These organisms are the food of fish, birds, and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river¡¯s edge or on the sea shore that people realize what is happening.
Where do the substances which pollute water come from? There are two main sources, sewage(ÎÛË®) and industrial waste. As more detergent (Ï´µÓ¼Á)is used in homes, more of it is finally put into our rivers, lakes and seas. Detergents harm water birds by breaking down the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous materials in it, such as copper and lead.
So if we want to stop this pollution, the answer is simple. Sewage and industrial waste must be made clean before flowing into the water reservoirs. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.

Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills(·ç³µ) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(ÄëËé) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost. Today, there is a global movement to supply more and more of our electricity through the use of wind.

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, ¡°Can I invent a pair of glasses that could be changed by the wearer?¡± He designed two plastic lenses£¨Í¸¾µ£©that are filled with a special liquid. Using syringes£¨×¢ÉäÆ÷£©you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don¡¯t have electricity and cannot afford batteries, to use it. The radio has a generator (·¢µç»ú) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (Õæ¿Õ) cleaner which uses something called ¡°cyclonic separation¡± to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It¡¯s possible to jump to incredible heights out of the water ¡ª over 30 feet. The basic fly-board model comes in at ¡ê4,200.
So keep dreaming and inventing. One day you might get it right.

A victim of climate change
A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July£®

Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals£® That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April£®
Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change£®

To get a chocolate out of a box requires a lot of unpacking: the box has to be taken out of the paper bag in which it arrived, the cellophane (²£Á§Ö½) wrapper has to be torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not limited to luxuries. It is now becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.
The package itself is of no interest to the shopper, who usually throws it away immediately. Useless wrapping accounts for much of the refuse put out by the average London house-hold each week. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up valuable energy and resources and polluting the environment.
Recycling is already happening with milk bottles which are returned to the dairies (Å£Ä̳¡£©, washed out, and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles.
The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to throw away plastic altogether in the shops, a suggestion unacceptable to many producers who say there is no alternative (Ìæ´úÆ·) to their handy plastic packs.
It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers rather than producing new ones. Unnecessary packaging, intended to be used just once, and to make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of throwing away packaging as using it wisely. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.

Motherhood may make women smarter and may help prevent dementia(³Õ´ô) in old age by bathing the brain in protective hormones(ºÉ¶ûÃÉ) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may beprotected against diseases such as Alzheimer¡¯s(ÔçÀϳմôÖ¢). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
¡°Our research shows that the hormones of pregnancy(»³ÔÐ) are protecting the brain, including estrogen(´Æ¼¤ËØ),which we know has many neuroprotective (±£»¤Éñ¾µÄ) effects,¡± Kinsley said. ¡°It¡¯s rat data but humans are mammals just like these animals are mammals,¡± he added in a telephone interview. ¡°They go through pregnancy and hormonal changes.¡±Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer¡¯s and other forms of age-related brain decline.
¡°When people think about pregnancy, they think about what happens to babies and the mother from the neck down,¡±said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.¡°They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant¡ªthat is a great change in her behavior that showed in genetic alterations(¸Ä±ä) to the brain.¡±

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
¡°Humans constantly attribute(¹éÊô) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,¡± said Dr Kaminski.
¡°These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
¡¾Ð¡Ìâ1¡¿According to the passage, which of the following is TRUE?
| A£®The researchers made the test on dogs in eighty-four countries. |
| B£®Dogs always obey and don¡¯t steal forbidden food. |
