考题 共用题干 第二篇Around 45%of the UK's carbon dioxide emissions come from the energy people use every day-at home and when they travel.In order to generate that energy,fossil fuels(coal oil,and gas)are burnt,and these produce greenhouse gases-in particular carbon dioxide(CO2).Car emissions are a major problem, but the truth is that more CO2 comes from the energy used at home.The average household creates aroundfive and a half tonnes of CO2 a year,and it is the same CO2 that is changing the climate and damaging the environment.CO2 and various other gases wrap the earth in an invisible blanket helping to prevent heat from escaping.Without this greenhouse effect,the average temperature on Earth would be around-18℃, compared with the current average of around+15℃.The composition of this blanket of gases has remained relatively constant for many thousands of years.However,since the industrial revolution began around 200 years ago,people have been burning increasing amounts of fossil fuels,thus releasing more CO2 and other greenhouse gases in the process.This has increased the heating effect of the blanket,trapping more of the sun's energy inside the Earth's atmosphere in turn the Earth's temperature has increased more rapidly in a shorter period of time than it has for thousands of years.In 2008,the total UK CO2 emissions were 533 million tonnes.27%(144 million tonnes)of those emissions came from the energy used to heat,light,and power homes.Transport emissions caused by passenger cars,buses and motorcycles accounted for a further 16%(87 million tonnes)of the UK's CO2 emissions.These figures show that a significant amount of CO2 results from ordinary citizens carbon footprint in their daily activities and lifestyle.The effects of climate change can be seen all around us.Weather patterns are becoming more and more fractured and uncertain,and over the last century trends in warm weather have become increasingly common.In the UK in the last 40 years,winters have grown warmer,with much heavier rainfall.One of the clearest shifts over the last 200 years is towards summers that are hotter and drier,causing pervasive(普遍的)water shortages.Recent years have been the hottest since records began and during August 2003,the hottest ever outdoor temperature in the UK was recorded-38.5℃.Which of the following is the best title for the passage?A:Ways of reducing the UK's CO2 emissions.B:UK citizen's carbon footprint.C:The effect of industry on climate change in the UK.D:Changes in weather patterns in the UK.

考题 共用题干 Ear BreakthroughNew research published in the journal Current Biology has added significantly to understand-ing of how the ear works,giving hope to millions of deaf and hard of hearing people.The latest research,conducted by Dr. T. Albet,a Deafness Research UK research fel-low at the UCL Ear Institute,together with scientists at the University of Cologne,shows that fruit flies have ears which mechanically amplify sound signals in a remarkably similar way to the senso- ry(感觉的)cells found in the inner ear of vertebrates(脊椎动物)including humans. The finding means that the wealth of genetic techniques already available to study the fruit fly can now be used to target how the ear works.Dr. Albert says.“The biophysical parallels between the ways both fruit flies and humans convert sound into nerve signals are truly amazing.We may be allowed to hope that these mecha- nistic(机械学的)similarities extend further down to the genes and molecules that bring about hearing.But even if it finally should turn out that hearing in fruit flies relies on different mole-cules than does hearing in humans,the little fruit fly can help us find answers to some key ques-tions of hearing research and -what is sometimes even more important -will surely help us ask the right questions.”The work is welcomed by Deafness Research UK,the country's only medical research charity for deaf people.Vivienne Michael,chief executive of Deafness Research UK.says,“This is an important advance that paves the way toward a clear understanding of the genetics of deafness.The charity will continue to support culling-edge(尖端的)research through its Fellowship programme at the UCI.Ear institute and at other top research centres in the UK to achieve our goal of secu-ring audial improvements in the prevention,diagnosis and treatment of all forms of hearing impair-ment.”There are nine million deaf and hard of hearing people in the UK and in most cases deafness results from loss of sensory cells in the inner ear known as“hair” cells.The cells can be damaged and lost through ageing,noise,genetic defects and certain drugs and,because the cells don't re- generate,the result is progressive— and irreversible—hearing loss .Damage to these cells can al-so lead to tinnitus(耳鸣),which affects around five million people in the UK. Hearing loss caused by damage to the sensory cells_______.A:.can affect five million people in the UKB:.can be progressively repairedC:cannot be curedD: cannot lead to tinnitus

考题 资料:2014 has been a landmark year for Alibaba. Just last week, the Chinese e-commerce juggernaut set a world-record selling US$9.3 Billion worth of goods in 24 hours on Singles Day. A few months back, Alibaba claimed the title of the world's biggest IPO, raising US$25 Billion on the NYSE. Things will only get bigger for Alibaba. On the back of the historic signing of the China-Australia Free Trade Agreement yesterday, Alibaba announced in Melbourne their continued commitment to bringing Australian products, brands and businesses closer to China's online consumers via it's Alipay payment platform and Taobao Marketplace. Alipay is the largest online payment service provider in China. With more than 800 million Chinese accounts, Alipay is already the biggest mobile payment processor in the world. It clears 80 million transactions per day, including 45 million transactions through it's Alipay Wallet mobile app and processed US$780 billion worth of transactions in the year ended June 30. Alipay is one of six financial services entities that will fall under the umbrella of Ant Financial Serviced Group, a rebranding of Alipay Financial Services. There are plans to take this money making machine public too. Alipay Australia has been established as a local entity that will work with its joint venture partner, pay bang to help Australian businesses and merchants access Alipay's cross-border payment solutions. Alipay has also been working with Australia Post to sell, distribute and promote the Alipay Purchase Card across 4,400 retail outlets for Australian shoppers to use on the Tmall.com and Taobao Marketplace platforms. Alipay's extension into Australia, follows its move into the U.S with the launch of its ePay payment program, which handles everything from payment processing and currency translation for U.S. retailers. How many transactions does Alibaba clear every day without using Alipay Wallet mobile app? A.35 million. B.45 million. C.780 million. D.80 million.

考题 共用题干 1.Tired of social networking?Logging off Facebook?You're probably not the only one.Fearing for their privacy or perhaps just bored with using the site,100,000 Britons are said to have deactivated(注销)their accounts last month. And Facebook fatigue seems to be catching. Six million logged off for good in the U.S.too,figures show.Worldwide,the rate of growth has slowed for a second month in a row一and as it aims to reach its goal of one billion active users,Facebook is having to rely on developing countries to boost its numbers.The figures suggest that there could be a"natural limit" for Facebook's saturation(饱和).There is even speculation on blogs that, as is feared for its failing rival MySpace,the website could one day "pass into oblivion"(被人遗忘).2.Earlier this year,executives announced that the number of Facebook accounts held in the UK had reached 30 million,accounting for about half the population.The milestone was an increase of four million from last July and represented the highest saturation of any country in Europe.3.But times change一and last month more than 100,000 in the UK stopped using the website, figures show.In the U.S.,user numbers dropped from 155.2 million to 149.4 million throughout May.In Canada there was also a fall,of about 1.5 million users,while in Russia and Norway num-bers also fell by more than 100,000 users.4.It's not all bad news for the site.Worldwide,Facebook is still expanding and has around 600 million users,thanks to strong growth in countries such as Mexico and Brazil.5.According to Eric Eldon,of the website Inside Facebook,which obtained the figures through analysis of the company's advertising tools,there is a point at which the site can no longer grow, once it has established itself in a country."By the time Facebook reaches around 50 percent of the total population in a given country,growth generally slows to a halt,"he explained.Facebook had strong growth in countries such as_________.A:around 50 percent of the total population in a given countryB:highest saturationC:5.8 millionD:Britain,Canada and the U.S.E:fear for privacy or perhaps just being bored with using the siteF:Mexico and Brazil
