Section C 26 Adults are getting smarter about how smart babies

18、 are. Not long ago, researchers learned that 4-day-old could understand【 B1】 _and subtraction. Now, British research psychologist Graham Schafer has discovered that infants can learn words for uncommon things long before they can speak. He found that 9-month-old infants could be taught, through repe

But parents eager to teach their infants should take note: even without being taught new words, a control group【 B10】 _the other infants within a few months. “This is not about advancing development,“ he says. “Its just about what children can do at an ea

Teenagers in Australia,【 C3】_said that their mobile phones provided numerous benefits and were an【 C4】_part of their lives; some were so【 C5】 _to their phones that the researchers considered it an addiction.

30、)By 2075, the United Nations mid-range projection for global population is about 9.5 billion. This means that there could be an extra three billion mouths to feed by the end of the century, a period in which substantial changes are anticipated in the wealth, calorie intake and dietary preferences of

31、 people in developing countries across the world. Such a projection presents mankind with wide-ranging social, economic, environmental and political issues that need to be addressed today to ensure a sustainable future for all. One key issue is how to produce more food in a world of finite resources

32、 B)Today, we produce about four billion metric tonnes of food per year. Yet due to poor practices in harvesting, storage and transportation, as well as market and consumer wastage, it is estimated that 30-50% of all food produced never reaches a human stomach. Furthermore, this figure does not refl

33、ect the fact that large amounts of land, energy, fertilisers and water have also been lost in the production of foodstuffs which simply end up as waste. This level of wastage is a tragedy that cannot continue if we are to succeed in the challenge of sustainably meeting our future food demands. Where

34、 Food Waste Happens C)In 2010, the Institution of Mechanical Engineers identified three principal emerging population groups across the world, based on characteristics associated with their current and projected stage of economic development. Fully developed, mature, post-industrial societies, such

35、as those in Europe, characterised by stable or declining populations which are increasing in age. Late-stage developing nations that are currently industrialising rapidly, for example China, which will experience declining rates of population growth, coupled with increasing affluence(富裕 )and age pro

36、file. Newly developing countries that are beginning to industrialise, primarily in Africa, with high to very high population growth rates, and characterised by a predominantly young age profile. D)Each group over the coming decades will need to address different issues surrounding food production, s

37、torage and transportation, as well as consumer expectations, if we are to continue to feed all our people. E)In less-developed countries, such as those of sub-Saharan Africa and South-East Asia, wastage tends to occur primarily at the farmer-producer end of the supply chain. Inefficient harvesting,

38、inadequate local transportation and poor infrastructure(基础设施 )mean that produce is frequently handled inappropriately and stored under unsuitable farm site conditions. F)In mature, fully developed countries such as the UK, more-efficient farming practices and better transport, storage and processing

39、 facilities ensure that a larger proportion of the food produced reaches markets and consumers. However, characteristics associated with modern consumer culture mean produce is often wasted through retail and customer behaviour. G)Major supermarkets, in meeting consumer expectations, will often reje

40、ct entire crops of perfectly edible fruit and vegetables at the farm because they do not meet exacting marketing standards for their physical characteristics, such as size and appearance. H)Of the produce that docs appear in the supermarket, commonly used sales promotions frequently encourage custom

41、ers to purchase excessive quantities which, in the case of perishable foodstuffs, inevitably generate wastage in the home. Overall between 30% and 50% of what has been bought in developed countries is thrown away by the purchaser. Better Use of Our Finite Resources I)Wasting food means losing not on

42、ly life-supporting nutrition but also precious resources, including land, water and energy. As a global society, therefore, tackling food waste will help contribute towards addressing a number of key resource issues. J)Land Usage: Over the last five decades, improved farming techniques and technolog

43、ies have helped to significantly increase crop yields along with a 12% expansion of farmed land use. However, a further increase in farming area without impacting unfavourably on what remains of the worlds natural ecosystems appears unlikely. The challenge is that an increase in animal-based product

44、ion will require more land and resources, as livestock(牲畜 )farming demands extensive land use. K)Water Usage: Over the past century, human use of fresh water has increased at more than double the rate of population growth. Currently about 3.8 trillion m3 of water is used by humans per year. About 70

45、 of this is consumed by the global agriculture sector, and the level of use will continue to rise over the coming decades. L)Better irrigation can dramatically improve crop yield and about 40% of the worlds food supply is currently derived from irrigated land. However, water used in irrigation is o

46、ften sourced unsustainably. In processing foods after the agricultural stage, there are large additional uses of water that need to be tackled in a world of growing demand. This is particularly crucial in the case of meat production, where beef uses about 50 times more water than vegetables. In the

47、future, more effective washing techniques, management procedures, and recycling and purification of water will be needed to reduce wastage. M)Energy Usage: Energy is an essential resource across the entire food production cycle, with estimates showing an average of 7-10 calories of input being requi

48、red in the production of one calorie of food. This varies dramatically depending on crop, from three calories for plant crops to 35 calories in the production of beef. Since much of this energy comes from the utilisation of fossil fuels, wastage of food potentially contributes to unnecessary global

49、warming as well as inefficient resource utilisation. N)In the modern industrialised agricultural process which developing nations are moving towards in order to increase future yields energy usage in the making and application of fertilisers and pesticides represents the single biggest component. Wheat production takes 50% of its energy input for these two items alone. Indeed, on a global scale, fertiliser manufacturing consumes about 3-5% of the worlds annual
