　　ADHD Linked to Air Pollutants

　　Children have an increased risk of attention problems，seen as early as grade school , if their moms 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 in 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 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 woman's blood would also be available to the baby in her womb. Nine years later, the researchers investigated signs of attention problems in these children, now age 9. They asked each child's mother a series of questions. These included whether her child had problems doing things that needed sustained(長(zhǎng)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 10 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 as likely to have children who showed attention problems by age 9. The new findings were published November 5 in the journal PLOS ONE.

　　New research lights the way to super-fast computers

　　1)New research published today in the journal Nature Communications, has demonstrated how glass can be manipulated 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 Southampton, has found it is possible to change 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 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. Optical fibres are used to send information around the world at the speed of light, but these signals then have to be converted to electrical signal sonce 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 like 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 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 information. 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 developed and used in next-generation computer memory technology known as CRAM, which may ultimately be integrated with the advances reported.

　　Why Buy Shade-Grown Coffee?

　　When people argue about whether coffee is good for health, they're usually thinking of the health of the coffee drinker. Is it food for your heart? Does it increase blood pressure? Does 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(樹(shù)冠)of taller indigenous(土生土長(zhǎng)的)trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun coffees. At first, this increases production because more coffee bushes can be planted if there aren’t 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 the tall trees and migrating birds rest there.(環(huán)球網(wǎng)校2015職稱(chēng)英語(yǔ)考試?yán)砉ゎ?lèi)A級(jí)真題練習(xí)題)

　　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 poisoned 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 such labels as "shade grown" and "bird friendly." Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it's worth it.

　　31.What is the main idea of this passage?

　　A. Farmers are changing the way they grow coffee.

　　B. Coffee is becoming more expensive to produce.

　　C. Shade-grow coffee is more expensive than sun-grow coffee.

　　D. People should buy shade-grown coffee.

　　32. The function of the word "Traditionally" in Paragraph 2 is to show_____.

　　A. the positive effects of coffee.

　　B. a change of coffee growth.

　　C. something that is the most important.

　　D. how coffee production used to be

　　33.What does increased production of full-sun coffee bring about?

　　A. More insects.

　　B. Better quality coffee.

　　C. Larger farms.

　　D. Higher profits.

　　34.How do farmers find more land for growing full-sun coffee?

　　A. They buy more land from other farmers.

　　B. They cut down trees.

　　C. They move to another country.

　　D. They turn grassland into farmland.

　　35. The full-sun method may affect the following EXCEPT_____ full sun

　　A. insects.

　　B. air.

　　C. birds.

　　D. humans

　　Explore Jordan

　　Wadi Rum is the name given to a valley cut into the sandstone and hard rock in southwest Jordan. _______________46 The name Rum most likely comes from an Aramaic word meaning “high” or “elevated”, The area around Wadi Rum is now also one of Jordan’s most important tourist destinations, and attracts an increasing number of foreign tourists, particularly trekkers(越野者)，but also for camel safaris(旅行) or simply day-trippers from Aqaba or Petra. In contrast, there are almost no local or Arab tourists through nearby disi attracts young people from Amman at the weekends.

　　Popular activities in the desert environment include camping under the stars, riding Arab horses, and rock-climbing amongst the massive rock formations. Jebal Rum (Jebal means mountain) is 1,574 meters above sea level. ___________47

　　But Jordan is not simply a desert environment-----it also contains the area which is the lowest point to the face of the Earth----the incredible Dead Sea, popular with tourists for swimming. _______48 Once the waters reach the Dead Sea they are landlocked and have nowhere to go, so they evaporate, leaving behind a dense, rich cocktail(混合的) of salts and minerals that supply industry, agriculture and medicine with some of its finest products. Once again, tourists benefit and can participate in water spa treatments and water therapies.

　　The Dead Sea is located in the syro-African Rift, a 4,000-mile fault line in the Earth’s crust. The lowest point of dry land on Earth is the shoreline of the Dead Sea at 1,300 feet below sea level. Because the lake is at the lowest point, this means that water does not drain from it. ______49 Figures for the Dead Sea’s salinity(鹽度) today range from 25% to 35%.

　　But the greatest tourist attraction is the incredible city of Petra.______50 It is a vast unique city, carved into the sheer rock face by the Nabataeans, an industrious Arab people who settled here more than 2,000 years ago, turning it into an important junction for the silk, spice and other trade routes that linked China India and southern Arabia with Egypt, Syria, Greece and Rome. Today, visitors can marvel at the architecture and explore life as it was thousands of years ago.

　　A It is the largest wadi (riverbed) in Jordan.

　　B It is the second highest peak in Jordan, rising directly above the Rum valley opposite Jebal Urn Ishrin.

　　C This vast stretch of water receives a number of incoming rivers, including the River Jordan.

　　D The area has been used as a background setting in a number of films.

　　E Every day seven million tons of water evaporate from the lake, but the minerals remain causing the salt content to increase.

　　F It is without doubt Jordan’s most valuable treasure.
