9、estions 1-13, which are based on Reading, Passage 1 below.The 9 Billion-People QuestionThe worlds population will grow from almost 7 billion now to over 9 billion in 2050. John Parker asks if there will be enough food to go round.A THE 1.6-hectare (4-acre) Broadbalk field lies in the centre of Rotha
10、msted farm, about 40km (25 miles) north of London. In 1847 the farms founder, Sir John Lawes, described its soil as a heavy loam resting on chalk and capable of producing good wheat when well manured. The 2010 harvest did not seem to vindicate his judgment. In the centre of the field the wheat is ab
11、undant, yielding 10 tonnes a hectare, one of the highest rates in the world for a commercial crop. But at the western end, near the manor house, it produces only 4 or 5 tonnes a hectare; other, spindlier, plants yield just 1 or 2 tonnes.B Broadbalk is no ordinary field. The first experimental crop o
12、f winter wheat was sown there in the autumn of 1843, and for the past 166 years the field, part of the Rothamsted Research station, has been the site of the longest-running continuous agricultural experiment in the world. Now different parts of the field are sown using different practices, making Br
13、oadbalk a microcosm of the state of world farming.C The wheat yielding a tonne a hectare is like an African field, and for the same reason: this crop has had no fertiliser, pesticide or anything else applied to it. African farmers are sometimes thought to be somehow responsible for their low yields,
14、 but the blame lies with the technology at their disposal. Given the same technology, European and American farmers get the same results. The wheat bearing 4 or 5 tonnes a hectare is, roughly, like that of the Green Revolution, the transformation of agriculture that swept the world in the 1970s. It
15、has been treated with herbicides and some fertilisers, but not up to the standard of the most recent agronomic practices, nor is it the highest-yielding semi-dwarf wheat variety. This is the crop of the Indian subcontinent and of Argentina. The extraordinary results in the centre of the field are ac
16、hieved by using the best plants, fertilisers, fungicides and husbandry. The yield is higher than the national average in Britain, and is as good as it gets.D But the Broadbalk field shows something else. A research paper recently published tracks its yields from the start, showing how the three diff
17、erent kinds of wheat farmingAfrican, Green Revolution and modernhave diverged, sometimes quite suddenly: in the 1960s with the introduction of new herbicides for Green Revolution wheat, and in the 1980s with new fungicides and semi-dwarf varieties. Worryingly, though, in the past 15 years the yields
18、 of the most productive varieties of wheat in Broadbalk have begun to level out or even fall. The fear is that Broadbalk may prove a microcosm in this respect, too.E At the start of 2011 the food industry is in crisis. World food prices have risen above the peak they reached in early 2008. That was
19、a time when hundreds of millions of people fell into poverty, food riots were shaking governments in dozens of developing countries, exporters were banning grain sales abroad and land grabs carried out by rich grain- importing nations in poor agricultural ones were raising awkward questions about ho
20、w best to help the poor. This time, too, there have been export bans, food riots, panic buying and emergency price controls, just as in 2007-2008. Fears that drought might ruin the current wheat crop in China, the worlds largest, are sending shock waves through world markets. Discontent over rising
21、bread prices has played a part in the popular uprisings throughout the Middle East. There are differences between the periods, but the fact that agriculture has experienced two big price spikes in four years suggests that something serious is rattling the worlds food chain.F The food industry has be
22、en attracting extra attention of other kinds. For years some of the most popular television programmes in English-speaking countries have been cooking shows. That may point to a healthy interest in food, but then again it may not. The historian Livy thought the Roman Empire started to decay when coo
23、ks acquired celebrity status.G At a meeting of the Group of Eight (G8) industrial countries in 2009 the assembled leaders put food alongside the global financial crisis on their list of top priorities, promising to find $20 billion for agriculture over three years. This year the current president of
24、 the Group of 20 (G20), Frances Nicolas Sarkozy, wants to make food the top priority. The Gates Foundation, the worlds richest charity, which had previously focused on health and development generally, started to concentrate more on feeding the world. At last months World Economic Forum, a gathering

29、rrect letter, A-H, in boxes on your answer sheet. As the epitome of world farming, Broadbalk field has three different kinds of wheat production: that with the lowest output represents U U 8 /U /Uand the reason is that there is no U U 9 /U /Uto use. The area with moderate yield implies U U 10 /U /U,
30、 which had happened during the U U 11 /U /Uin 1970s. The reason for this situation is that the fertilisers and pesticides used are all lower than the criterion in the U U 12 /U /U. The highest crop output happened in the centre of the Broadbalk and its yield is even higher than that in U U 13 /U /U.

32、battling more than a dozen blazes in southern California are having such difficulty containing the flames, despite better preparedness than ever and decades of experience fighting fires fanned by the notorious Santa Ana winds. The wildfires themselves, experts say, generally are hotter, move faster,
33、 and spread more erratically than in the past.B The short-term explanation is that the region, which usually has dry summers, has had nine inches less rain than normal this year. Longer term, climate change across the West is leading to hotter days on average and longer fire seasons. Experts say thi
34、s is likely to yield more megafires like the conflagrations that this week forced evacuations of at least 300,000 resident in Californias southland and led the president to declare a disaster emergency in seven counties on Tuesday.C Megafires, also called siege fires are the increasingly frequent bl

One of the current wildfires is the sixth biggest in California ever, in terms of acreage burned, according to state figures and news reports. The trend to more superhot fires, experts say, has been dri
36、ven by a century-long policy of the U.S. Forest Service to stop wildfires as quickly as possible. The unintentional consequence was to halt the natural eradication of underbrush, now the primary fuel for megafires. Three other factors contribute to the trend, they add. First is climate change marked
37、 by a 1-degree F. rise in average yearly temperature across the West. Second is a fire season that on average is 78 days longer than in the late 1980s. Third is increased building of homes and other structures in wooded areas.D We are increasingly building our homes.in fire-prone ecosystems, says Do
38、minikKulakowski, adjunct professor of biology at Clark University Graduate School of Geography in Worcester, Mass. Doing that in many of the forests of the Western U.S. .is like building homes on the side of an active volcano. In California, where population growth has averaged more than 600,000 a y
39、ear for at least a decade, housing has pushed into such areas. What once was open space is now residential homes providing fuel to make fires burn with greater intensity, says Terry McHale of the California Department of Forestry firefighters union. With so much dryness, so many communities to catch
40、 fire, so many fronts to fight, it becomes an almost incredible job.E That said, many experts give California high marks for making progress on preparedness since 2003, when the largest fires in state history scorched 750,000 acres, burned 3,640 homes, and killed 22 people. Stung then by criticism o

Firef
42、ighters unions that then complained of dilapidated equipment, old fire engines, and insufficient blueprints for fire safety are now praising the states commitment, noting that funding for firefighting has increased despite huge cuts in many other programmes. We are pleased that the Schwarzenegger ad
43、ministration has been very proactive in its support of us and come through with budgetary support of the infrastructure needs we have long sought, says Mr. McHale with the firefighters union. Besides providing money to upgrade the fire engines that must traverse the mammoth state and wind along serp
44、entine canyon roads, the state has invested in better command-and-control facilities as well as the strategies to run them.G In the fire sieges of earlier years, we found out that we had the willingness of mutual-aid help from other jurisdictions and states, but we were not able to communicate adequ

After a 2004 blue-ribbon commission examined and revamped those procedures, the statewide response has become far more professional and responsive, he says.H Besides ordering the California N
46、ational Guard on Monday to make 1,500 guardsmen available for firefighting efforts, Gov. Arnold Schwarzenegger asked the Pentagon to send all available Modular Airborne Fighting Systems to the area.
