If their noses inhaled(吸入)a certain type of air pollution when they were pregnant. That's the finding of a new study. Released when things aren't burned completely, this pollution is known as polycyclic aromatic hydrocarbons, or PAHs. The biggest sources of these PAHs: the burning of fossil fuels, wood and trash.Frederica Perera works at Columbia University's Mailman School of Public Health is New York City. She researches how exposure to things in the environment affects children's health in a new study, she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women in New York City. Because burning tobacco can spew(排放)PAHs into the air and lungs, Perera's team focused on nonsmokers.

The reason Any PAHs in a woman's blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs of attention problems in those children, now age 9. They asked each child's mother a series of questions. These included whatever her childhad problems doing things that needed sustained(长期的)mental effort, such as homework or games with friends. The scientists also asked if the kids had trouble following instructions or made frequent, careless mistakes. All of these can be symptoms of a disorder called Attention Deficit Hyperactivity Disorder, or ADHD. About one in U.S. children has ADHD.Among the women studied, traffic and home heating were the primary sources of air pollution exposure, Perera and her team suspect. Some of these women had low levels of PAHs in their blood. Ohters had high levels. Those with high levels were five times as likely to have children who showed attention problems by age 9.

Paintings thatdepict(描述)famous people and historical scenes cover office buildings and freeway walls all access the city. With a collection of more than 2,000 murals, Los Angeles is the unofficial mural capital of the world.But the combination of graffiti(涂鸦), pollution, and hot sun has left many L.A. murals in terrible condition. _____(46)in the past, experts say, little attention was given to caring for public art. Artists were even expected to maintain their own works, not an easy task with cars racing by along the freeway._____(47)The work started in 2003. So far, 16 walls have been selected and more may be added later.Until about 1960, public murals in Los Angeles were rare. But in the 1960s and 1970s, young L.A. artists began to study early 20th-century Mexican mural painting_____(48)The most famous mural in the city is Judith Baca's "The Great Wall," a13-foot-high(4-meter-high)painting that runs for half a mile (0.8 kilometer) in North Hollywood, _____(49)it took eight years to complete—400 underprivileged teenagers painted the designs—and is probably the longest mural in the world.One of the murals that will be restored now is Kent Twitchell's "Seventh Street Altarpiece." which he painted for the Los Angeles Olympics in 1984. _____ (50) Twitchell said, "it was meant as a kind of gateway through which the traveler to L.A. must drive. The open hands represent peace."Artists often call murals the people's art. Along a busy freeway or hidden in a quiet neighborhood, murals can teach people who would never pay money to see fine art in a museum, "Murals give a voice to the silent majority," said one artist.A. The city trying to stop the spread of graffiti, has painted over some of the murals complete.B. This striking work depicts two people facing each other on opposite sides of the freeway near downtown Los Angeles.C. Artists like murals because they like the work of Mexican artists.D. Now the city is beginning a huge project to restore the city's murals.E. The mural represents the history of ethnic groups in California.F .Soon, their murals became a symbol of the city's cultural expressions and a showcase for L.A.'s cultural diversity.更多职称英语考试免费资料请访问“新东方在线职称英语频道”。
