         Scientists have devised（发明） a way to determine roughly where a person has lived using a strand 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 your hair,” said Thure Cerling, a geologist at the University of Utah.
While U.S. diet is relatively identical（同一的）, water supplies vary. The differences result from weather patterns. The chemical composition of rainfall changes slightly as rain clouds move.
Most hydrogen and oxygen atoms in water are stable, but traces of both elements are also
present as heavier isotopes. The heaviest rain 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（同位素） along a strand of hair, scientists can construct a geographic timeline. Each inch of hair corresponds（相当） to about two months.
Cerling’s team collected tap water samples from 600 cities and constructed a map 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 rain systems.
“It’s not good for pinpointing（精确）,” Cerling said. “It’s good for eliminating many possibilities.”
Told 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”.
72. 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.
C. Hair analysis accurately identifies criminal suspects.
D. The chemical composition of hair varies from person to person.
73. What does the author mean by “You’re what you eat and drink” (Line 1, Para.3)?
A. Food and drink affect one’s personality development.
B. Food and drink preferences vary with individuals.
C. Food and drink leave traces in one’s body tissues（组织）.
D. Food and drink are similar to one’s existence.
74. What did Cerling’s team produce in their research?
A. A map showing the regional differences of tap water.
B. A collection of hair samples from various barber shops.
C. A method to measure the amount of water in human hair.
D. A chart illustrating the movement of the rain system.
75. 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.

Koeler took special notice of the tall woman who was nicely dressed, but she was wearing ugly, thick-soled(厚底) shoes.
　　Now the woman was taken to a room for questioning. There it was found that the soles of the shoes were hollow(中空的). They were opened. Some diamonds fell out on the floor. Their total weight was 3377 carats(克拉).
　　The young woman broke down in tears. Then she told her story. For years she had dreamed of coming to live in America, she said. At last she had managed to get the papers she needed to come to the U.S. Then a strange man called on her. He said he would pay for her trip and give her one hundred dollars. All she had to do was to smuggle the diamonds past the U.S. Customs. The man gave her the shoes and also bought her a plane ticket. Just before she got on the plane, he gave her an envelope. He said that it was the hundred dollars he had promised.
　 The weeping woman handed the envelope to Koeler. He tore it open. There was only eighteen dollars. She was cheated. In the end the woman was trialed and sentenced to eighteen months in prison for her part in the smuggling.

Doctors have known for a long time that extremely loud noises can cause hearing damage or loss.The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little mire than one second to be affected.

An American scientist has found that using aspirin (阿斯匹林) increase the temporary (暂时的)hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great.

The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise.

.One conclusion you can draw from the passage is that aspirin________.

A. makes hearing damage from loud noise worse

B. should never be taken more than four grams

C.can damage one’s hearing when it is given more than four grams daily

3..

. The American scientist did his experiment in order to find ________.
