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

8、nonsmoking pregnant women in New York City. Because burning tobacco can spew（排放 ）PAHs intothe 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

9、of each woman during pregnancy. 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 of attention problems in those children, now age 9. They asked each childs mother a series of questions. These included whatever

10、 her child had problems doing things that needed sustained（長(zhǎng)期的 ）mental effort, such as homework or gameswith 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 Hype

11、ractivity 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 level

26、rchF.description of the HTML page第四部分：閱讀理解第一篇 Why Buy Shade-Grown Coffee?When people argue about whether coffee is good for health, theyre 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 a

27、ffects 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 becau

28、se 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 migratingbirds rest the

29、re.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

30、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 friendl

31、y. 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.

35、 鳥(niǎo)D.humans 人類第二篇More Rural Research is NeededAgricultural research funding is vital if the world is to feed itself better than itdoes now. Dr. Tony Fischer, crop 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

36、 to stay ahead.“The global decline in investment in international agricultural research must be reversed if significant progress is to be made towards reducing malnutrition（營(yíng)養(yǎng)不良 ）andpoverty. ” he sa id.Research is needed to solve food production, land degradation（貧瘠化 ）and environmentalproblems. Secu

37、re 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 itself in the first 25years, when the world s population is expected to rise from 5 X to X billion people. He said that things will probably hold or imp

38、rove 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 southern 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.

39、The major improvement will be in East Asia, South America and South-East Asia.The debeloping world was investing about 0.5%, or $8 billion 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 co

40、untries.He said crop research could produce technologies that spread across many countries, such as wheat production research having spin-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 appl

41、ication, so that money can be used very efficiently.”Dr. Fischer said.Yields of rice, wheat ad maize（ 玉米 ）havegrown impressively 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

42、 this growth such as high-yield varieties, fertilizers, and irrigation, were becoming exhausted.“If you want to save theland for non-agricultural activities, for forests and wildlife, you re going to have toincrease yield. ” Dr. Fischer said.36.

48、s await babies with altitudeWomen 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 ave

49、rage. But it wasnt 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 st

50、udied the 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

51、 found that 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

52、 by this 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

53、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 to he

54、art trouble in adulthood, for example. Low birthweight is a risk factor for coronary（冠狀的 ） heart disease. And newborns with a highratio 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 wealthy fa

55、milies 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 are on average lighte

56、r 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 Paragraph 4 that.A. the finding was

57、 unexpectedB. 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 their mother.C. different family backgrounds.D.

58、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 hormones before birth.D. new born wealthy families have larger he

Paintings that depict（

60、描述 ）famous peopleand 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（涂鴉 ）, pollution, and hot sun has left many L.A. muralsin terrible

61、 condition. （46）in the past, experts say, little attention was given tocaring 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.U

62、ntil 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 Bacas The Great Wall, a 13-foot-high(4- meter-high)painting that runs for half a mile (0.8 k

63、ilometer) 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 Twitchells Seventh StreetAltarpiece. which he painted for the Los Angeles Olympics in

64、 1984. (50) Twitchellsaid, 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
