31、gue 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 affects the health of the human population in other ways, too.Traditionally, coffee bush

32、es 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. At first, this increases production because more coffee bushes can be planted if there arent any trees. With increased production c

33、ome 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.Furthermore, in the long term, the full-sun method also damages the ecosystem because mo

34、re 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 eventua

35、lly 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 were paying for the health of the bi

36、rds, the land, ourselves, and the planet. I think its 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 co

37、ffee.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

38、.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

Dr. Tony Fischer, crop scientist, said demand wasgrowing at 2.5% per year but with modern technologies and

40、 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 reducing malnutrition(营养不良)and poverty.” he said.Research is needed to solve food production, l

41、and degradation(贫瘠化)and environmental problems. Secure local food supplies led to economic growth which is turn, slowed population growth. Dr. Fischer painted a picture of the worlds ability to feed itself in the first 25 years, when the worlds population is expected to rise from 5 X to X billion pe

42、ople. He said that things will probably hold or improve but therell 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 see

43、n 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 billion a year, of its agricultural gross domestic product(GDP)on research and developed world was spending 2.5% of it

44、s 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 spin-offs(有用的副产品)for Mexico, China or India.“Technologies still need to be refined for the local conditions but a lo

45、t of the strategic research can have global application, so that money canbe 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 b

46、etween 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 land for non-agricultural activities, for forests and wildlife, youre going to have to increase yield.” Dr. Fischer said.36、 What is

47、the passage mainly about?A 、 Shortage of food supplies.B 、 Development of agricultural technologies.C 、 Impact of agricultural research.D 、 Expectation of population growth.37、 Which of the following statements is true about the worlds agricultural research funding?A 、 It is increasing among develop

48、ed countries.B 、 It is decreasing worldwide.C 、 Less is demanded from developing countries.D 、 Most of it is spent very efficiently.38、 What is the picture of Asias food supplies in the first 25 years?A 、 Food shortage will not be a problemB 、 There will be more hungry people in southern Asia.C 、 Po

49、pulation growth will result in more hungry people.D 、 There will be fewer hungry people in East Asia.39、 What does Dr. Fischer say about technologies?A 、 They are costly.B 、 They have to be improved to meet local needs.C 、 Their application is limited.D 、 They have to be applied locally.40、 It can b

50、e infered from the last paragraph that_.A 、 there is a demand for saving land for non-agricultural activities.B 、 crop production is growing faster in developing countries.C 、 maize production reached its peak in the 1990s.For example, maize production rose from 2 to 8 tonnes per hectare between 195

51、0 and 1995D 、 technologies improving maize production have been well developed.根据材料，回答题。第三篇Dangers 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 d

52、isease and strokes.Research has hinted that newborns in mountain communities are lighter than average. But it wasnt clear whether this is due to reduced oxygenlevels at high altitude or because their mothers are under-nourished many people who live at high altitudes are relatively poor compared with

53、those living lower down.To find out more, Dino Giussani and his team at Cambridge University studied the records of 400 births in Bolivia during 1976 and 1998. Thebabies 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 kilome

54、ters above sea level, while Santa Cruz is much lower, at 0.44 kilometers.Sure enough, Giussani found that the average birthweight of babies in La Paz was significantly lower than in Santa Cruz. This was true in bothhigh and low-income families. Even babies born to poor families in Santa Cruz were he

55、avier on average than babies born to wealthy families in lofty La Paz. We were very surprised 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 ofhormones that regulate growth of the un

56、born child, says Giussani.His team also found that high-altitude babies tended to have relatively larger heads compared with their bodies. This is probably because a fetusstarved of oxygen will send oxygenated blood to the brain in preference to rest of the body.Giussani wants to find out if such ba

57、bies have a higher risk of disease in later life. People born in La Paz might be prone to heart trouble inadulthood, for example. Low birthweight is a risk factor for coronary(冠状的) 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 wealthy families are heaver.B 、 Women living at high altitude tend to give birth to underweight babies.C 、 Newb
