   There was a time when a trip to the supermarket in the United States often ended with a seemingly simple question from the cashier, "Paper or plastic？"Well, which type of bag would you choose？

While both types of bags have some influence on the environment, it has long been supposed that paper bags are kinder. They are made from a renewable source, are broken down easily, burn without giving off thick smoke and can be recycled. However, the producing process behind paper bags uses more energy than that of plastic ones. How can this be true？

Studies show that paper bag production requires four times as much energy as plastic bag production.

And the amount of water used to make them is twenty times higher. Besides, the influence on forests is very serious. It takes about fourteen million trees to produce ten billion paper bags, which happen to be the number of bags used in the United States yearly. In terms of recycling, the idea that paper bags are more environment friendly than plastic ones can be quickly discarded. Research shows it requires about 98% less energy to recycle plastic than it does to recycle paper.

Even though paper bags might be more harmful than plastic ones, plastic still seems to be considered as the more harmful of the two by governments. In Ireland, for example, a tax has been introduced to discourage the use of plastic bags. People have to pay 22 cents for every plastic bag, and as a result, their use has dropped quickly.

There’s no doubt that it makes more sense to reuse these bags. However, we don’t seem to be doing that at present. That may be because they fall apart quickly. If so, cloth bags are a better choice, but still, their production also has a bad influence on the environment. So what to do? How should we answer the question of “Paper or plastic?” It seems that we first need to ask ourselves one more general question: “What can I do to help the environment?”

   Most artists have a favorite material they like to work with. For Kristen Alyce, it happens to be trash (废物). The eco-conscious designer uses her talent to transform garbage like empty drink bottles and Skittles wrappers into wonderful outfits (全套服装) that sell for thousands of dollars.

Kristen says the idea came to her after she saw how much waste she and her three college roommates produced on a daily basis. The Fine Arts student began to dream about transforming the bags and packages into beautiful clothes. Her first dress made of plastic bags and rolled magazines was unusual, funny and even fascinating. However, she only made it to test how she could create a beautiful dress with trash.

The young designer did not consider starting a commercial business until she spent a week working at Couture Fashion Week in New York City. There she observed the excitement caused by new looks and decided to see if her unusual idea would result in as much enthusiasm. She began by creating a line of 12 garbage-inspired dresses. They were a big success and Garbage Gone Glam was born!

Today the company produces a wide variety of outfits that range from cocktail dresses to ballgowns. Kristen, of course, doesn’t search for trash cans as her material any more. Since the designer can work with anything from brochures to yellow pages, from directory pages to candy wrappers, finding “trash” is never a problem.

However, if you think the garbage-inspired women dresses come cheap, think again. The price for ready made creations sold on the company’s site varies from $500 to $1,500. Those seeking custom (定制的) dresses have to pay as much as $2,000. Though those may appear expensive, the designer says that she has no shortage of customers. In fact thanks to so many requests she now even has trash-inspired outfits for men that include jackets, ties, trousers and even board shorts! While most of the outfits are hard enough to bear various wearing methods, whether they can be cleaned is a little unclear.

【小题1】What was the purpose of Kristen’s first dress made of trash?

A．To earn money.	B．To recycle trash.
C．To test her creativity.	D．To amuse others.

【小题2】We can learn from the passage that Garbage Gone Glam (Paragraph 3) is the name of ______.

A．a company	B．a model
C．a dress	D．a school

【小题3】What do we know about Garbage Gone Glam according to the passage?

A．Its creations sell well at cheap prices online.

B．It was founded by Kristen and her college roommates.

C．It has little difficulty in finding the material for its products.

D．It produces various clothes only for women at present.

【小题4】Which of the following words can best describe Kristen Alyce?

A．Generous and creative.

B．Enthusiastic and sensitive.

C．Considerate and eco-friendly.

D．Creative and eco-friendly.
