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.

Scientists have devised a way to determine roughly where a person 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 your hair,” said Thure Ceiling, 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 rain 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 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 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 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 (精确定位),” Ceding 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.”
61. According to the passage scientists’ new discovery is that          .
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.

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.
D. Food and drink are indispensable to one’s existence.

A. There is much more rainfall in California than in Utah.
B. The water it delivers becomes lighter when it moves inland.
C. Its chemical composition is less stable than in other areas.

My father came to the United States as a Ukrainian immigrant (移民) when he was 14 years old. Unable to speak English but willing to do anything to succeed, he learned the language, became a barber, and opened up his own business in a small town. He put my sister and me through college during a time when most people thought that women didn’t need an education and that they should be satisfied with getting married and having children. He gave us values and ambition. But this story didn’t really start until my father was 60 years old.

    I was preparing to get married and my father was attempting to practice the polke, a must at any Ukrainian wedding. But he just couldn’t do it! He had lost mobility in his leg and was diagnosed with a brain tumor (肿瘤). After surgery, this energetic, hard-working man was forced to retire as a result of significant paralysis (瘫痪) in his right arm and leg. My dad had always worked two jobs and spent his spare time working around the house. Now that kind of life came to a sudden stop. Yet never once did he complain. He bought rubber balls and spent his days trying to regain his hand mobility by squeezing those balls over and over.

    After his last operation, he chatted with me pleasantly in the hospital room until a nurse flew into the room, waving her finger at me, and yelling, “You’d better tell your father to stay in bed. He is paralyzed and will never walk again. He needs to stop trying to get out of bed and accept the fact that he can’t walk now or ever. I am sick of picking him up and you’d better warn him to stay put!” My father smiled. He spent a great deal of time on the floor that year, but he eventually got up and walked.

    My father lived nineteen more years after that operation. He bought himself a motor scooter (小型摩托车) and spent years zipping around the streets of Philadelphia. He was proud, free, and always smiling.
