Recently scientists have worked out a way to judge roughly where a person has lived using strands(缕) of hair, a technique that could help track the movements of criminal suspects or unidentified bodies .
The method depends on measuring how chemical variations in drinking water show up in people’s hair.
While U.S diet is relatively identical, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as 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（列阵）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 establish 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 frame 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),” he said. “It’s good for ruling out many possibilities.”
64. What can we learn from the passage about the latest 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.
C. Hair analysis identifies criminal suspects accurately.
D. The chemical composition of hair varies from person to person.
65. What does the underlined word “identical” in paragraph 3 probably mean?
A. similar B. fantastic C. beneficial D. healthy
66. What is the practical value of Cerling’s research?
A. It helps analyze the quality of water in different regions.
B. It helps the police determine where a crime is committed.
C. It helps the police narrow down possibilities in detective work.
D. It helps identify the drinking habits of the person under investigation.
The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site.
Web sites offering cheap goods and services should be regarded with care.
On-line shoppers who enter their credit-card information may never receive the goods they thought they bought.

ot lucky. Their names, addresses and credit-card numbers were posted on a Web site after the retailer refused to pay US $157, 828 to get back the information.
Credit-card firms are now fighting against on-line fraud. Mastercard is working on plans for Web — only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated.

And shop only at secure sites; Send your credit-card information only if the Web site offers advanced secure system.
If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The Website address may also start https: //—the extra “s” stands for secure. If in doubt, give your credit-card information over the telephone.

Watercolor is the o
ldest paints known. It dates back to the early cave men who discovered they could add lifelike qualities to drawings of animals and other figures on the walls of caves by mixing the natural colors found in the earth with water.
Fresco (壁画), one of the greatest of all art forms, is done with watercolor. It is created by mixing paints and water and applying these to wet plaster （灰泥）. Of the thousands of people who stand under Michelangelo’s heroic ceiling in the Sistine Chapel, very few know that they are looking at perhaps the greatest watercolor painting in the world.
The invention of oil painting by the Flemish masters in the fifteenth century made fresco painting go downhill, and for the next several centuries watercolor was used mainly for doing sketches（草图）or as a tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have a widely-known love for outdoors and also small private pictures. The softness of watercolor had a remarkably strong attraction for them.
The popularity of watercolor continued to grow until the twentieth century. The United States passed England as the center for watercolor, producing such well-known watercolor artists as Thomas Eakins and Andrew Wyeth.The purpose of the passage is to introduce ________.
| A．the gradual weakness of fresco painting |
| B．oil’s power or influence over watercolor |
| C．the discovery of watercolor in England |
| D．the start and development of watercolor |
In the 16th and 17th centuries the artists thought ________.
| A．watercolor was softer, and thus better. |
B．Oil pai nting lasted longer, and was better. |

| D．Watercolor was too hard to use in any works. |
According to the passage, watercolor painting was put back in England because ______.
| A．it was easy to use outdoors | B．it was a strong medium（媒介） |
