Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste-disposal problem becomes increasingly difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot as a dumpsite. Residents or trash haulers(垃圾托运者) would transport household rubbish, rotted wood, and old possessions to the site. Periodically(定期的) some of the trash was burned and the rest was buried. The unpleasant sights and smells caused no problem because nobody lived close by.

    Factories, mills, and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted remains into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices unacceptable to modern society. The first problem is space. Dumps, which are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. Property is either too expensive or too close to residential(住宅区的)neighborhoods. Long-distance trash hauling has been a common practice, but once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is almost nonexistent.

    Awareness of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    Recycling efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    Belgium is divided into three communities. Each one has its own language and traditions. But the people of Belgium are untied in their love for Belgian potato fries. The fries are prepared and sold the same way in all area of the country.

    The Reuters news service reports that potatoes reached Belgium in the 16^th century. But it was not until the 19^th century that restaurants and others began selling fried potatoes throughout the country as a separate meal.

    Recently, a Belgian group launched a campaign aimed at getting the United Nations (UN) to recognize the popular treat. The group wants the UN's Educational, Scientific and Cultural Organization to place the food on its cultural heritage (遗产) list.

    The UNESCO list recognizes more than 300 objects, beliefs and practices. They include Turkish coffee and the traditional Chinese theater known as Peking opera. The list also includes a dance, the Argentinian tango, and the singing of the Aka pygmies of the Central African Republic. UNESCO says the list is “made up of intangible heritage elements (非物质文化遗产元素) that help show the diversity of heritage and raise awareness about its importance”.

    Belgian potato fries are traditionally sold in a paper wrapper，or cone, in a “fritkot” There are about 5,000 frikots in Belgium. That means they are 10 times more common as a percentage of the population as McDonald's restaurants in the United States. The national organization of fritkot owners says the small, often unfurnished buildings are much like Belgium itself. It says these buildings combine the country's acceptance of disorder with a dislike of structures that all look the same. The group says 95 percent of Belgians visit a fried potato hut at least once a year.

    Chinese consumers' crazy appetite for luxury goods and services appears unstoppable,with just 2 percent of the Chinese population responsible for one-third of the world's luxury items.

    As China's economic miracle develops,the market opportunities for all sorts of luxury goods and services are increasing.Luxury consumption in China now extends ways beyond well-known car,clothing and jewelry brands.For example,the luxury jet market in China is the fastest-growing in the world,even outstripping that of the United States, with a market share of 25 percent.This trend appears to continue,with 20 to 30 percent growth expected in China, compared with only 2 to 3 percent in the US.But more importantly,China's luxury jet market growth represents a major development in the private consumption of luxury items.

    China's high-quality red wine market also provides evidence of the growth in private consumption of luxury goods.In 2013,China became the largest market for red wine in the world,even overtaking France,with l.86 billion bottles consumed in China last year.Over the past five years,China's red wine consumption has grown 136 percent.

    According to my ongoing consumer research in this area while working at the University of International Business and Economics in Beijing,public consumption of such expensive global luxury brands such as Prada and Armani is easily explained by the desire to "gain face" and publicly display social climbing through material possessions.On the other hand,it is "self-reward" that lies behind consumer motivation in this area.Chinese consumers who have experienced rapid financial and economic gains appear particularly prone to the need to reward themselves for their success.But this has little to do with "gaining face" and impressing others and much more to do with the need for personal contentment.

    Finally,the growth in private luxury consumption in China is set to continue in part due to the maturity of the Chinese consumer and advancement of Chinese consumer culture generally.

    People have always wanted to know what the future will look like. Then, how can we? {#blank#}1{#/blank#} The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago, such as food, sleep, the feeling of being appreciated and loved. {#blank#}2{#/blank#} No. In addition, generally speaking, the inventions for the last 150 years have been a human effort for freedom and communication, to be able to get in control of the time and world. Since there is still much to do in this area, this will be the focus at least for the next 150 years.

    But why do we need to predict the future? Predicting the future is important for two reasons: First, we need to start to think about what kind of future we would like for ourselves and to pass on to the next generation. {#blank#}3{#/blank#}

    How about the virtual worlds? It might be in the future to experience the sand between your toes, and hear the waves, just lying in your bed at home. {#blank#}4{#/blank#} So, even if a great invention is there for an affordable price, it'll never take the place of the common experience if it is not real.

    {#blank#}5{#/blank#} What we'll see in the next 50 years is the transition (过渡) from an oil-dependent society to a new society. Here there'll be new medicine, continued exploration of space, challenges in the climate change, and new inventions that make life a little easier.

A. So what will the future look like then?

B. Will this change in the next 150 years?

C. Predicting the future can help us in many ways.

D. However, you'll never get the feeling of being there.

E. Well, to understand the future, you must know the past.

F. However, no matter how real the experience will feel, it doesn't happen for real.

G. Then we need to know what decisions we need to make today that will give the best result in the future.

Any schoolchild knows that a whale breathes through its blowhole. Fewer know that a blowhole is a nostril （鼻孔） slightly changed by evolution into a form more useful for a mammal that spends its life at sea. And only a dedicated expert would know that while toothed whales, such as sperm whales, have one hole, baleen （鲸须） whales, such as humpback and Rice whales, have two. 

Even among the baleen whales, the placing of those nostrils differs. In some species they are close together. In others, they are much further apart. In a paper published in Biology Letters Conor Ryan, a marine biologist at the Scottish Association for Marine Science, suggests why that might be. Having two nostrils, he argues, helps whales smell in stereo （立体空间）. 

Many types of baleen whales eat tiny animals known as zooplankton （浮游动物）， which they catch by filtering （过滤） them from seawater using the sheets of fibrous baleen that have replaced teeth in their mouths. But to eat something you first have to find it. Toothed whales do not hunt by scent. In fact, the olfactory bulb-the part of the brain that processes smell-is absent in such creatures. But baleen whales still have olfactory bulbs, which suggests smell remains important. And scent can indeed give zooplankton away. Zooplankton like to eat other tiny creatures called phytoplankton （浮游植物）. When these are under attack, they release a special gas called dimethyl sulphide, which in turn attracts baleen whales. 

Most animals have stereoscopic senses. Having two eyes, for instance, allows an animal to compare the images from each in order to perceive depth. Having two ears lets them locate the direction from which a sound is coming. Dr Ryan theorized that paired blowholes might bring baleen whales the same sorts of benefits. 

The farther apart the sensory organs are, the more information can be extracted by the animal that bears them. The researchers used drones to photograph the nostrils of 143 whales belonging to 14 different species. Sure enough, baleen whales that often eat zooplankton, such as the North Atlantic right whale, have nostrils that are farther apart than do those, such as humpback whales, that eat zooplankton occasionally. Besides allowing them to breathe, it seems that some whales use their blowholes to determine in which direction dinner lies. 

Not only is second-hand shopping good for the planet and your wallet, but new research finds that the more conscious(关注的) of style you are, the more likely you are to shop for second-hand clothes.

It is often assumed that those who shop for second-hand clothes do so to save money or reduce their impact on the environment. In fact, according to the research. style-consciousness is a bigger predictor of second-hand shopping than frugality or eco-consciousness.

Style-consciousness is very different from fashion-consciousness. Fashion is all about the "new" , and is constantly evolving. Style, on the other hand, is about expressing long-term individual identity.

Fashion shoppers are used to a continuous supply of new trends and fast fashion products. Fast fashion works quickly to replicate ( 复制) an ever-moving stream of fashion trends, generating large volumes of low-quality clothes. The impact of fast fashion on the environment is significant and well-documented. Globally ,the fast fashion industry creates 92 million tons of waste per year. Less than 15 percent of clothes are recycled or reused.

A style-conscious person expresses themselves through their clothes. These shoppers want second-hand clothes that show their personal style and values. They look for authentic and original pieces and avoid mainstream trends and fast fashion. They buy clothes that are timeless, well-made and all ow them to express their individual identity.

Going against the fast fashion trend, growing numbers of people are shopping for second-hand clothing. And the number of second-hand stores is also increasing. The research suggests much of this growth is due to shoppers considering themselves to be style-conscious.

We hope with increasing numbers of second-hand stores, markets and online platforms selling a range of quality, pre-loved clothes at different price points for different budgets—coupled with the growing acceptance of second-hand shopping—shoppers will consider buying second-hand more often. Not only are you helping the planet, you are also likely to be doing it with style.
