资料：Up to 80 per cent of the world’s middle classes will live in developing countries by 2030 thanks to surprising recent gains in poverty reduction, according to a United Nations report published on Thursday. “Never in history have the living conditions and prospects of so many people changed so dramatically and so fast.” concludes the UN’s latest Development Report. “The world is witnessing an epochal ‘global rebalancing’.” Underpinning the improvements in the human development index（HDI） was rapid growth in countries such as China, India and Brazil, with China and India having doubled per capita economic output in less than 20 years. But the study stressed that growth and improvements in HDI spread far beyond the four Bric countries of Brazil, Russia, India and China, and included at least 40 countries that had accompanied greater economic dynamism with effective poverty-reduction policies. Afghanistan, Sierra Leone, Ethiopia, Rwanda and Angola were among 14 countries that have recorded gains in HDI of more than 2 per cent a year since 2000. Partly as a result, the report found that worldwide extreme income poverty has plunged from 43 per cent in 1990 to just 22 per cent in 2008, including more than 500m being lifted out of poverty in China alone. The report stated that such gains had already helped the world achieve the main poverty eradication goal of the so-called Millennium Development Goals, which called for the share of people living on less than $1.25 a day to be cut by half from 1990 to 2015. Underpinning this poverty reduction was developing countries’ increasing share of global trade, which grew from 25 per cent to 47 per cent between 1980 and 2010. “The south as a whole is driving global economic growth and societal change for the first time in centuries,” says the report. The report found that trade among developing countries was the biggest factor in that expansion, increasing from less than 10 per cent of total global trade to more than 30 per cent. “Trade between countries in the south will overtake that between developed nations,” the report said.The word “underpinning” in the passage refers to ______.A.blocking B.undergoing C.supporting D.stressing

资料：Economic performance is improving in most of the world's leading economies but is still short of a self-sustaining upswing, the Organization for Economic Cooperation and Development said on Wednesday. In an update to its economic forecasts, the Paris-based international organisation representing advanced economies said that more private sector investment was needed for the expansion to endure, for wages to rise sustainability and for inequalities to be tackled. Although all leading economies are now recording positive growth, Catherine Mann, the OECD's chief economist, urged governments to “curb your enthusiasm [ because] strong and sustained medium-term global growth is not yet secured”. The OECD's economic outlook shows upgrades to the 2017 growth forecasts in China, Russia and Europe excluding the UK with the world outlook also appearing stronger in 2018. World growth should rise from a low of 3.1 per cent in 2016, to 3.5 per cent this year and 3.7 per cent in 2018, the OECD forecast, with the US, the Eurozone, Brazil and Russia contributing most to the improved global outlook. China's predicted growth rate of 6.8 per cent in 2017 and 6.6 per cent in 2018 has been revised higher by 0.2 percentage points in both years and although India's growth rate has been revised down, reflecting adjustment to its new goods and services tax, it is likely to remain the fastest growing large economy in the world. Only the UK, which remains embroiled in Brexit negotiations, has a deteriorating outlook. Responding to the OECD's forecast that the British economy will be the slowest growing in the Group of Seven in 2018 having been near the top of the league table in 2016, the British Treasury said it was not complacent.What is the best title for the passage？A.The prosperity of the leading economies B.The engine of the world economy C.China，the trail blazer of the world economy D.Global economy improving but lacks self-sustaining upswing

共用题干 American DreamsThere is a common response to America among foreign writers:the US is a land of extremes where the best of things are just as easily found as the worst. This is a cliche（陈词滥调）.In the land of black and white,people should not be too surprised to find some of the biggest gaps between the rich and the poor in the world.But the American Dream offers a way out to everyone._______(46)No class system or government stands in the way.Sadly,this old argument is no longer true.Over the past few decades there has been a fundamental shift in the structure of the American economy.The gap between the rich and the poor has widened and widened._______( 47)Over the past 25 years the median US family income has gone up 18 per cent.

There are now 37 million Americans living in poverty.At 12.7 per cent of the population,it is the highest per centage in the developed world.Yet the tax burden on America's rich is falling,not growing._______(50)There was an economic theory holding that the rich spending more would benefit everyone as a whole.But clearly that theory has not worked in reality.__________（48）A:Nobody is poor in the US.B:The top 1 per cent of households has seen its tax bite fall by a full 25 percentage points since 1980.C:For upper class families they have risen 41 per cent.D:Now it is 9.8 times.E:As it does so,the possibility to cross that gap gets smaller and smaller.

共用题干第二篇Home HeatingCentral heating became popular only after the Civil War.Typically,coal-burning furnaces（火炉）fueled the early systems.Natural gas had developed into the leading fuel by 1960.Its acceptance resulted in part from its wide uses.Because it comes primarily from U.S.and Canadian fields , natural gas is also less vulnerable（脆弱的）than oil is to war.Oil remains the most important fuel in a few areas,such as New England.Electric heating dominates most areas with mild winters and cheap electricity,including the South and the Northwest.It was made popular at least in the South by the low cost of adding electric heating to new houses built with air-conditioning.Bottled gas,which is somewhat more expensive than utility gas,is the fuel of choice in rural areas not served by utility pipelines.Wood is the leading heating fuel in just a few rural counties.Home heating,which accounts for less than 7 per cent of all energy consumed in the U.S.,has had a commendable（值得赞扬的）efficiency record : from 1 978 to 1 997 , the amount of fuel consumed for this purpose declined 44 per cent despite a 33 per cent increase in the number of housing units and an increase in house size.TheU.S.Department of Energy,however,forecasts that energy used in home heating will rise by 14 per cent over the next two decades.That rise is small considering an expected 21 per cent increase in the number of houses and the trend toward larger houses.Natural gas and electricity will probably dominate the home heating market for the next two decades.Solar（太阳的）heating never became popular because of cost and limited winter sunlight in most areas;in 2000 only 47,000 homes relied on it.What fuel is the dominant fuel in New England?A:Gas.B:Electricity.C:Wood.D:Oil.
