T

5、hats the finding of a new study. Released when things arent 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 Universitys Mailman School of Public

6、Health in 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 in New York City. Because burning tobacco can spew（排放） PAHs into the air and lungs, Per

7、eras team focused on nonsmokers. The researchers wanted to probe（探查） other sources of PAHs, ones that would have been hard for an individual to avoid.The team started by testing the blood of each woman during pregnancy. The reason: Any PAHs in a womans blood would also be available to the baby in he

8、r womb. Nine years later, the researchers investigated signs of attention problems in these children, now age 9. They asked each childs mother a series of questions. These included whether her child had problems doing things that needed sustained（长期的） mental effort, such as homework or games with fr

9、iends. 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 10 U.S. children has ADHD.Among the women studied, traffic and home h

10、eating 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 as likely to have children who showed attention problems by age 9. The new findings were p

The main purpose of the research was to find out how exposure to PAHs played a role in harming the subjects physical health.18. Nonsmoking mothers w

12、ere selected because the effect of smoking on PAHs was unclear.19. The blood of each women was tested once a month during pregnancy.20. Kids with ADHD commonly fail in school.21. The women with high levels of PAHs in their blood were more likely to have kids with ADHD22. Traffic and home heating wer

13、e considered to be the biggest sources of PAHs for the subjects in the research.第三部分：概况大意与完成句子New research lights the way to super-fast computers1）New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated to create a material that will allow com

14、puters 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 Southampton, has found it is possible to ch

15、ange the electronic properties of amorphous chalcogenides, a glass material integral to data technologies such as CDs and DVDs. By using a technique called ion doping, the team of researchers have discovered a material that could use light to bring together different computing functions into one com

16、ponent, 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. Optical fibres are used to send information around the w

17、orld at the speed of light, but these signals then have to be converted to electrical signalsonce 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 light to carry information around a computer. Much l

18、ike how the web uses light to deliver information, we want to use light to both deliver and process 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 how a widely used glass can be manipulated to cond

19、uct 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 information. In doing so, this could transform the comput

Is it food for your heart? Does it increase blood pressure? D

24、oes it help you concentrate? However, coffee affects the health of the human population in other ways, too.Traditionally, coffee bushes were planted under the canopy（树冠）of taller indigenous（土生土长的）trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees

25、. At first, this increases production because more coffee bushes can be planted if there arent any trees. With increased production come increased profits.Unfortunately, deforesting for coffee production immediately decreases local-wildlife habitat. Native birds nest and hide from predators（捕食者）in t

26、he tall trees and migrating birds rest there.Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, but then the birds eat the poi

27、soned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with s

28、uch labels as shade grown and bird friendly. Sure, these varieties might cost a little more. But were paying for the health of the birds, the land, ourselves, and the planet. I think its worth it.31.【题干】What is the main idea of this passage? 文章的主旨是A.Farmers are changing the way they grow coffee. 农民正
