If

7、 their noses inhaled(吸入)a certain type of air pollution when they were pregnant. Thats the finding of a new study. Released when things arent burned completely, this pollution is known as polycyclic aromatic hydrocarbons(多环芳烃), or PAHs. The biggest sources of these PAHs: the burning of fossil fuels,

8、 wood and trash.Frederica Perera works at Columbia Universitys Mailman School of Public Health is New York City. She researches how exposure to things in the environment affects childrens health in a new study, she and her team studied the exposure to air pollution of 233 nonsmoking pregnant women i

9、n New York City. Because burning tobacco can spew(排放)PAHs into the air and lungs, Pereras team focused on nonsmokers. The researchers wanted to probe(探查)other sources of PAHs, ones thats would have been hard for an individual to avoid.The team started by testing the blood of each woman during pregna

10、ncy. The reason Any PAHs in a womans blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs ofattention problems in those children, now age 9. They asked each childs mother a series of questions. These included whatever her child had problems doin

11、g 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 disordercalled Attention Deficit Hyperactivity Disorder(注意缺陷多动障碍),

12、 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. Others had high levels. Those with high levels were five times a

The new findings were published November 5 in the journal PLOS ONE.16.Perera and her team chose nonsmoking pregnant women all over America.A.RightB.WrongC.Not mentioned【答案】B 17.The main purpose of the research was to find out how expos

17、d to create a material that will allow computers to transfer information using light. This development could significantly increase computer processing speeds and power in the future.2)The research by the University of Surrey, in collaboration with the University of Cambridge and the University of S

18、outhampton, has found it is possible to change the electronic properties of amorphous chalcogenides(非晶硫), a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping(离子掺杂), the team of researchers have discovered a material that could use light tobring

19、 together different computing functions into one component, leading to all-optical systems.3)Computers currently use electrons to transfer information and process applications. On the other hand, data sources such as the internet rely on optical systems; the transfer of information using light. Opti

20、cal fibres are used to send information around the world atthe speed of light, but these signals then have to be converted to electrical signals once they reach a computer, causing a significant slowdown in processing.4)The challenge is to find a single material that can effectively use and control

21、light to carry information around a computer. Much like how the web uses light to deliver information, we want to use light to both deliver andprocess computer data, said project leader, Dr.Richard Curry of the University of Surrey.5)This has eluded researchers for decades, but now we have now shown

22、 how a widely used glass can be manipulated to conduct negative electrons, as well as positive charges, creating what are known as pn-junction devices. This should enable the material to act as a light source, a light guide and a light detector -something that can carry and interpret optical informa

23、tion. In doing so, this could transform the computers of tomorrow, allowing them to effectively process information at much faster speeds.6)The researchers expect that the results of this research will be integrated into computers within ten years. In the short term, the glass is already being devel
