The January fashion show, called FutureFashion, exemplified (例证) how far green design has come. Organized by the New York-based non-profit Earth Pledge, the show inspired many top designers to work with sustainable fabrics (纤维) for the first time. Several have since made pledges to include organic fabrics in their lines.
The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to find. "Most designers with existing labels are finding there aren’t comparable fabrics that can just replace what you’re doing and what your customers are used to," he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents.
Those who do make the switch are finding they have more support. Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs (企业家) who attend its two springtime shows in Los Angeles and New York and gave special recognition to designers whose collections are at least 25% sustainable. It now counts more than 50 green designers, up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative aimed at helping cotton farmers go organic: it will buy transitional (过渡型的) cotton at higher prices, thus helping to expand the supply of a key sustainable material. "Mainstream is about to occur," says Hahn.
Some analysts (分析师) are less sure. Among consumers, only 18% are even aware that ecofashion exists, up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted consumer. When asked if she owned any sustainable clothes, she replied: "Not that I’m aware of." Like most consumers, she finds little time to shop, and when she does, she’s on the hunt for "cute stuff that isn’t too expensive." By her own admission, green just isn’t yet on her mind. But—thanks to the combined efforts of designers, retailers and suppliers—one day it will be.
We learn from Paragraph 3 that designers who undertake green fashion ______.

A:can attend various trade shows free B:are readily recognized by the fashion world C:can buy organic cotton at favorable prices D:are gaining more and more support

Why Buy Shade-Grown Coffee? When people argue about whether coffee is good for health, they’re usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too. Traditionally, coffee bushes were planted under the canopy（树冠）of taller indigenous（土生土长的）trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t any trees. With increased production come increased profits. Unfortunately, deforesting for coffee production immediately decreases local-wildlife habitat. Native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there. Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink. Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But we’re paying for the health of the birds, the land, ourselves, and the planet. I think it’s worth it. What is the main idea of this passage?

A:Farmers are changing the way they grow coffee. B:Coffee is becoming more expensive to produce. C:Shade-grow coffee is more expensive than sun-grow coffee. D:People should buy shade-grown coffee.

Only the government can ensure that the American people have clean air and pure water. Congress must pass laws to stop manufacturers from polluting the air and water with the waste from their factories. Unless anti-pollution standards are enforced for all, companies that care about a clean environment will go out of business. For example, if Automobile Company X spends money to put an air-pollution control device on their automobiles, their cars will be more expensive than the cars produced by another company. People who don’t have the extra money or who don’t care about pollution will not buy the more expensive cars. Automobile Company X will go bankrupt(破产); that is, it won’t make enough money to pay its workers and to buy materials. It will then go out of business. Of course, no automobile company will make itself go bankrupt on purpose, and the pollution of the land and air and water will go on. But if the government says that all automobile manufacturers must make cars with air-pollution control devices, the cost of all manufacturers will be equal. So the government cannot let companies decide whether or not they want to stop pollution. The government must force manufacturers to clean up the environment by setting anti-pollution standards for everyone.If a company cares about a clean environment while others don’t, it will have to______.

A:change the anti-pollution standards for its products B:sell its products at a more expensive price C:buy materials at a higher price D:pay more money to its workers
