Many environmentalists and entrepreneurs are looking for ideas on how to “capture gold” ― that is, how to collect and convert plastic waste into new plastic or fuel.
OK, describing plastic waste as potential “gold” may be overdoing it. But the campaigners say that publicizing the notion that plastic is worth something may help reduce the amount of waste that ends up in oceans and the bellies of sea creatures.
To that end, they have set up a competition inviting members of the public to submit ideas online. Organizers will take the best ones to the Rio+20 Earth Summit (峰会) in Rio de Janeiro next month, where they are planning a daylong side event called Plasticity focusing on issues related to plastic pollution.
The plastic waste problem is gaining broader attention as environmentalists, scientists, manufacturers and the public become more aware of the sheer volume of the stuff that finds its way into the sea.
More than 260 million metric tons of plastic are now produced per year, according to the trade association PlasticsEurope. The majority of that is not recycled. Most of it ends up in landfill, and a significant amount ends up as litter on land, in rivers and in the oceans.
Technological advances have made clear that it is possible to reuse much of this plastic by turning it into fuel or new products. Yet the companies that have come up with such solutions have not achieved the economies of scale that would allow them to function profitably. Insufficient waste-collection and recycling systems in most countries also stand in the way of “ trash to cash” concept, said Doug Woodring, an environmental entrepreneur in Hong Kong who is among the organizer of the Plasticity forum(论坛) in Rio.
Rather than breast-beating, the form aims to highlight some of the technologies and ideas out there for collection and reuse. My personal favorite for now is a vacuum cleaner with plastic parts made from plastic waste.

Two new studies suggest that modern running shoes could increase the risk of injuries to runners.
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week. The runners were observed on a treadmill machine (跑步机). Sometimes they wore running shoes. Other times they ran barefoot (赤脚).
Researchers from the JKM Technologies company in Virginia, the University of Virginia and the University of Colorado did the study.
They found that running shoes create more stress that could damage knees, hips and ankle joints than running barefoot. They observed that the effect was even greater than the effect reported earlier for walking in high heels.
The study appeared in the official scientific journal of The American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They divided the runners into three groups. One group had always run shoeless. Another group had always run with shoes. And the third group had changed to shoeless running.
Runners who wear shoes usually come down heel first. That puts great force on the back of the foot. But the study found that barefoot runners generally land on the front or middle of their foot. That way they ease into their landing and avoid striking their heel.
Harvard’s Daniel Lieberman led the study. He says the way most running shoes are designed may explain why those who wear them land on their heels. The heel of the shoe is bigger and heavier than other parts of the shoe, so it would seem more likely to come down first. Also, the heel generally has thick material under it to soften landings.
But the researchers do not suggest that runners immediately start running barefoot. They say it takes some training. And there can be risks, like running when your feet are too cold to feel if you get injured.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website. What’s the main idea of the passage?
| A．Walking in high heels could cause less serious effects than running barefoot. |
| B．Two new discoveries encourage people to run in high heels. |
| C．Running in shoes is partly good to runners. |
| D．Two new studies prove running without shoes is beneficial to runners in most cases. |

“Cleverness is a gift while kindness is a choice. Gifts are easy – they’re given after all. Choices can be hard.” –– Jeff Bezos.
I got the idea to start Amazon 16 years ago. I came across the fact that the Internet usage was growing at 2,300 percent per year. I’d never seen or heard of anything that grew that fast, and the idea of building an online bookstore with millions of titles was very exciting to me. I had just turned 30 years old, and I’d been married for a year. I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn’t work since most start-ups don’t, and I wasn’t sure what to expect. MacKenzie told me I should go for it. As a young boy, I’d been a garage inventor. I’d always wanted to be an inventor, and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people, and I had a brilliant boss that I much admired. I went to my boss and told him I wanted to start a company selling books on the Internet. He took me on a long walk in Central Park, listened carefully to me, and finally said, “That sounds like a really good idea, but it would be an even better idea for someone who didn’t already have a good job.” That logic made some sense to me, and he convinced me to think about it for 48 hours before making a final decision. Seen in that light, it really was a difficult choice, but ultimately (最后), I decided I had to give it a shot. I didn’t think I’d regret trying and failing. And I suspected I would always be haunted by a decision to not try at all.
After much consideration, I took the less safe path to follow my passion, and I’m proud of that choice. For all of us, in the end, we are our choices.What inspired the author with the idea of building an online bookstore?

Men are spending more and more time in the kitchen encouraged by celebrity (名人) chefs like Gordon Ramsay and Jamie Oliver, according to a report from Oxford University.
The effect of the celebrity role models, who have given cooking a more manly picture, has combined with a more general drive towards sexual equality and men now spend more than twice the amount of time preparing meals than they did in 1961.
According to the research by Prof. Jonatahn Gershuny, who runs the Centre for Time Research at Oxford, men now spend more than half an hour a day cooking, up from just 12 minutes a day in 1961.
Prof. Gershuny said, “The man in the kitchen is part of a much wider social trend. There has been 40 years of sexual equality, but there is another 40 years probably to come.”
Women, who a generation ago spent nearly two hours a day cooking, now spend just one hour and seven minutes—a great fall, but they still spend far more time in the kitchen than men.
Some experts have named these men in aprons as “Gastrosexuals (men using cooking skills to impress friends)”, who have been inspired to pick up a kitchen knife by the success of Ramsay, Oliver as well as other male celebrity chefs such as Hugh Fearnley-Whittingstall, Marco Pierre White and Keith Floyd.
“I was married in 1974. When my father came to visit me a few weeks later, I was wearing an apron when I opened the door. He laughed,” said Prof. Gershuny. “That would never happen now.”
Two-thirds of adults say that they come together to share at least three times a week, even if it is not necessarily around a kitchen or dining room table. Prof. Gershuny pointed out that the family meal was now rarely eaten by all of its members around a table—with many “family meals” in fact taken on the sofa in the sitting room, and shared by family members. “The family meal has changed a lot, and few of us eat—as I did when I was a child—at least two meals a day together as a family. But it has survived in a different format.” What is one reason behind the trend that men spend more time cooking than before?
| A．The improvement of cooks’ status. |
| B．The influence of popular female chefs. |
| C．The change of female’s view on cooking. |
| D．The development of sexual equality campaign. |
What does the author think about the time men and women spend on cooking?
| A．Men spend more time cooking than women nowadays. |
| B．Women spend much less time on cooking than before. |
| C．It will take 40 years before men spend more time at the stove than women. |
| D．There is a sharp decline in the time men spend on cooking compared with 1961. |
How did Prof. Gershuny see the family meal according to the passage?
| A．It has become a thing of the past. |
| B．It is very different from what it used to be. |
| C．It shouldn’t be advocated in modern times. |
| D．It is beneficial to the stability of the family. |
Which is the best title for the passage?
| A．The Changes of Family Meals |
| B．Equality between Men and Women |
| C．Cooking into a New Trend for Men |
| D．Cooking—a Thing of the Past for Women |
The extraordinary Eastgate Building in Harare, Zimbabwe’s capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound(白蚁堆).
Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building—the country’s largest commercial and shopping complex—uses less than 10% of the energy of a conventional building of its size. The Eastgate’s owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn’t have to be imported.
The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium(天井) open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents(通风口). As it rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys.
During summer’s cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents.
This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature changes—days as warm as 31℃ commonly drop to 14℃ at night. “You couldn’t do this in New York, with its hot summers and cold winters,” Pearce said.
The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23℃ and 25℃, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh—far more so than in air-conditioned buildings, where up to 30% of the air is recycled. Why was Eastgate cheaper to be built than a conventional building?
| A．It was designed in a smaller size. |
| B．No air conditioners were fixed in. |
| C．Its heating system was less advanced. |
| D．It used rather different building materials. |
What does “it” refer to in Paragraph 3?
| A．Fresh air from outside. | B．Heat in the building. |
| C．Hollow space. | D．Baseboard vent. |
Why would a building like Eastgate Not work efficiently in New York?
| A．New York has less clear skies as Harare. |
| B．Its dampness affects the circulation of air. |
| C．New York covers a larger area than Harare. |
| D．Its temperature changes seasonally rather than daily. |
The data in the last paragraph suggests Eastgate’s temperature control system_____.
| A．allows a wide range of temperatures |
| B．functions well for most of the year |
| C．can recycle up to 30% of the air |
| D．works better in hot seasons |
