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.

Questions 62 to 66 are based on the following passage.
Scientists have devised a way to determine roughly where a person
23
has lived using a strand(缕) of hair , a technique that could help track the movements of criminal suspects or unidentified murder victims .
The method relies on measuring how chemical variations in drinking water show up in people‘s hair.
―You‘re what you eat and drink, and that‘s recorded in you hair,‖ said Thure Cerling, a geologist at the University of Utah.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as raid clouds move.
Most hydrogen and oxygen atoms in water are stable , but traces of both elements are also present as heavier isotopes (同位素) . The heaviest raid falls first .As a result, storms that form over the Pacific deliver heavier water to California than to Utah.
Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds to about two months.
Cerling‘s team collected tap water samples from 600 cities and constructed a mop of the regional differences. They checked the accuracy of the map by testing 200 hair samples collected from 65 barber shops.

They were able to accurately place the hair samples in broad regions roughly corresponding to the movement of raid systems.
―It‘s not good for pinpointing (精确定位),‖ Cerling said . ―It‘s good for eliminating many possibilities.‖
Todd Park, a local detective, said the method has helped him learn more about an unidentified woman whose skeleton was found near Great Salt Lake.
The woman was 5 feet tall. Police recovered 26 bones, a T-shirt and several strands of hair.
When Park heard about the research, he gave the hair samples to the researchers. Chemical testing showed that over the two years before her death, she moved about every two months.
She stayed in the Northwest, although the test could not be more specific than somewhere between eastern Oregon and western Wyoming.
―It‘s still a substantial area,‖ Park said ―But it narrows it way down for me.‖
62. What is the scientists‘ new discovery?
A) One‘s hair growth has to do with the amount of water they drink. B) A person‘s hair may reveal where they have lived.
