7、ew 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 Health is New York C

8、ity. 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, Pereras team focused on

9、 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 pregnancy. The reason Any PAHs in a womans blood would also be available to the baby in her womb. Nine yea

10、rs later, the researchers investigated signs of attention problems in those children, now age 9. They asked each childs mother a series of questions. These included whatever her child had problems doing things that needed sustained（ 長期的 ）mental effort, such as homework or games with friends. The sc

11、ientists 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 th

12、e 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. The new findings were published Novem

17、cate documents on the Internet with far greater accuracy than ever before. 2）The new system, witch was tested on photos and is now being applied to videos, shows for the first time that a machine learning algorithm（ 運算法則 ）for image recognition and retrieval is accurate and efficienti enough to imp

18、rove large-scale document searches online. The system uses pixel（ 像素 ）data in images and potentially video — rather than just text — to locate documents. It learns to recognize the pixels associatedwith a search phrase by studying the results from text-based image search engines. The knowledge gle

19、aned（ 收集 ）from those results can then be applied to other photos without tags or captions（ 圖片說明 ）,making for more accurate document search results. 3） “Over the last 30 years, ” says Associate Professor Korenzo Torresani, a co -author of the study, ” the web has evolved from a small collection of

20、 mostly text documents to a modern, massive, fast-growing multimedia datastet, where nearly every page includes multiple pictures of videos. When a person looks at a Web page, he immediately get the gist（ 主旨 ）of it by looking at the pictures in it. Yet, sruprisingly, all existing popular search eng

28、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（ 樹冠 ）of taller indigenous（ 土 生土長的 ）trees. However, more and more farmers in Latin America are deforesting the land to grow full-sun cof

29、fees. 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

30、（ 捕食者 ）in the 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 bir

31、ds 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 buyi

32、ng coffee with such 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. What is the main idea of this passage? 文章的主旨是 A.Farmers are changing the way

33、they grow coffee. 農(nóng)民正改變他們種咖啡的方式 B.Coffee is becoming more expensive to produce. 種植咖啡越來越貴 C.Shade-grow coffee is more expensive than sun-grow coffee. 蔽光生長的咖啡比向光生長的咖 啡貴 D.People should buy shade-grown coffee. 人們應(yīng)該買蔽光生長的咖啡 32.

37、op scientist, said demand was growing at 2.5% per year but with modern technologies and the development of new ones, the world should be able to stay ahead. “The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reduci

38、ng malnutrition（ 營養(yǎng)不良 ）and poverty. ” he sa id. Research is needed to solve food production, land degradation（ 貧瘠化 ）and environmental problems. Secure local food supplies led to economic growth which is turn, slowed population growth. Dr. Fischer painted a picture of the world ’ s ability to feed

39、 itse lf in the first 25 years, when the world ’ s population is expected to rise from 5 X to X billion people. He said that things will probably hold or improve but there ’ ll still be a lot of hungry people. The biggest concentration of poor and hungry people would be in sub-Saharan Africa and s

40、outhern Asia in 2020, similar to the currenti pattern. If there is any change, a slighe improvement will be seen in southern Asia, but not in sub-Saharan Africa. The major improvement will be in East Asia, South America and South-East Asia. The debeloping world was investing about 0.5%, or $8 billi

41、on a year, of its agricultural gross domestic product（GDP）on research and developed world was spending 2.5% of its GDP. Dr. Fischer said more was needed from all countries. He said crop research could produce technologies that spread across many countries, such as wheat production research having s

42、pin-offs（ 有用的副產(chǎn)品 ）for Mexico, China or India. “Technologies still need to be refined for the local conditions but a lot of the strate gic research can have global application, so that money can be used very efficiently. ” Dr. Fischer said. Yields of rice, wheat ad maize（ 玉米 ）havegrown impressive

43、ly in the past 30 years, especially in developing countries. For example, maize production rose from 2 to 8 tonnes per hectare between 1950 and 1995. But technologies driving this growth such as high-yield varieties, fertilizers, and irrigation, were becoming exhausted. “If you want to save the lan

44、d for non-agricultural activities, for forests and w ildlife, you ’ re going to have to increase yield. ” Dr. Fischer said. 36. What is the passage mainly about? A. Shortage of food supplies. 食物供應(yīng)短缺 B. Development of agricultural technologies. 農(nóng)業(yè)技術(shù)的發(fā)展 C. Impact of agricultural research. 農(nóng)業(yè)研究的影響

50、h altitude Women who live in the worlds highest communities tend to give birth to under-weight babies, a new study suggests. These babies may grow into adults with a high risk of heart disease and strokes. Research has hinted that newborns in mountain communities are lighter than average. But it w

51、asnt clear whether this is due to reduced oxygen levels at high altitude or because their mothers are under-nourished — many people who live at high altitudes are relatively poor compared with those living lower down. To find out more, Dino Giussani and his team at Cambridge University studied the

52、records of 400 births in Bolivia during 1976 and 1998. The babies were born in both rich and poor areas of two cities: La Paz and Santa Cruz. L Paz is the highest city in the world, at 3.65 kilometers above sea level, while Santa Cruz is much lower, at 0.44 kilometers. Sure enough, Giussani found t

53、hat the average birthweight of babies in La Paz was significantly lower than in Santa Cruz. This was true in both high and low-income families. Even babies born to poor families in Santa Cruz were heavier on average than babies born to wealthy families in lofty La Paz. "We were very surprised by thi

54、s result," says Giussani. The results suggest that babies born at high altitude are deprived of oxygen before birth. "This may trigger the release or suppression of hormones that regulate growth of the unborn child," says Giussani. His team also found that high-altitude babies tended to have relat

55、ively larger heads compared with their bodies. This is probably because a fetus starved of oxygen will send oxygenated blood to the brain in preference to rest of the body. Giussani wants to find out if such babies have a higher risk of disease in later life. People born in La Paz might be prone t

56、o heart trouble in adulthood, for example. Low birthweight is a risk factor for coronary（ 冠狀的 ） heart disease. And newborns with a high ratio of head size to body weight are often predisposed to high blood pressure and strokes in later life. 41. What does the new study discover? A. Babies born to

57、 wealthy families are heaver. B. Women living at high altitude tend to give birth to underweight babies. C. Newborns in cities are lighter than average. D. Low-altitude babies have a high risk of heart disease in later life. 42. Giussani and his team are sure that . A. babies born in Lance Paz

58、 are on average lighter than in Santa Cruz. B. people living at high altitudes tend to give birth to underweight babies. C. the birthweight of babies born to wealthy families is Santa Cruz. D. mothers in La Paz are commonly under-nourished. 43. It can be inferred from what Giussani says in Parag

59、raph 4 that . A. the finding was unexpected B. he was very tired. C. the study took longer than expected. D. he was surprised to find low-income families in La Paz. 44. The results of the study indicate the reason for the underweight babies is . A. lack of certain nutrition. B. powerty of th

60、eir mother. C. different family backgrounds. D. reduction of oxygen levels. 45. It can be learned about form the paragraph that . A. high-altitude babies tend to have high blood pressure in later life. B. under-weight babies have a shorter life span. C. babies born to poor families lack hormon

61、es before birth. D. new born wealthy families have larger heads compared with their bodies. 第5部分：補全短文（第46?50題，每題2分，共10分） 下面的短文有 5 處空白，短文后面有 6 個句子，其中 5 個取自短文，請根據(jù)短文內(nèi)容將其分別放回原 有位置，以恢復(fù)文章原貌。 Saving a Citys Public Art Avoiding traffic jams in Los Angeles may be impossible, but the citys colorful free

62、way murals（ 壁畫 ）can brighten even the worst commute. Paintings that depict（ 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 combinat

63、ion of graffiti（ 涂鴉 ）, 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)T

64、he 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 Judi

65、th Bacas "The Great Wall," a 13-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 re

66、stored now is Kent Twitchells "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 peoples 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," s
