Green Energy
1.Green energy is energy that is produced in a manner that has, less of a negative impact to the environment than energy sources like fossil fuels,which are often produced with harmful side effects."Greener" types of energy that often come to mind are solar,wind,geothermal and hydro energy.There are several more,even including nuclear energy,that is sometimes considered a green energy source because of its lower waste output relative to energy sources such as coal or oil.
2.The goal of green energy is generally to create power with as little pollution as possible produced as a by-product. Every form of energy collection will result in some pollution,but those that are green are known to cause less than those that are not. Most people who advocate greener sources of energy claim that the result of worldwide use of green energy will result in the ability to preserve the planet for a longer time.Greenhouse gases,a by-product of traditional sources of energy such as fossil fuels are thought to be causing global warming,or the process of the Earth heating up at an accelerated pace.
3.It is not completely necessary for green energy sources to come from places like solar or wind fields,which are examples of green"power plants".A green energy source can be a building that is designed in a way that it keeps itself cool in the daytime and heated in the night through its architectural design rather than having an air-conditioning or a heating system. The conservation of energy through architectural（建筑学的）design becomes, itself, a green energy source. Similarly, many sources of green energy can come directly from the area in which the energy is needed rather than from an outside source.
4.One of the goals of green energy technology is to take existing fossil fuel energy technology and clean it up so it is produced more cleanly. One such case is that of clean coal technology,where scientists are trying to find ways to extract energy from coal and other fossil fuels without all of the harmful side effects.The success of such these types of green energy depend upon the ability to extract harmful by-products from fossil fuels while not only being energy efficient,but by being cost efficient as well.

A.global warming
B.carbon emission
C.lower waste output
D.a green energy source
E.fossil fuels

[单选题]Text 1 Of all the changes that have taken place in English-language newspapers during the past quarter-century,perhaps the most far-reaching has been the inexorable decline in the scope and seriousness of their arts coverage.It is difficult to the point of impossibility for the average reader under the age of forty to imagine a time when high-quality arts criticism could be found in most big-city newspapers.Yet a considerable number of the most significant collections of criticism published in the 20th century consisted in large part of newspaper reviews.To read such books today is to marvel at the fact that their learned contents were once deemed suitable for publication in general-circulation dailies.We are even farther removed from the unfocused newspaper reviews published in England between the turn of the 20th century and the eve of World War II,at a time when newsprint was dirt-cheap and stylish arts criticism was considered an ornament to the publications in which it appeared.In those far-off days,it was taken for granted that the critics of major papers would write in detail and at length about the events they covered.Theirs was a serious business,and even those reviewers who wore their learning lightly,like George Bernard Shaw and Ernest Newman,could be trusted to know what they were about.These men believed in journalism as a calling,and were proud to be published in the daily press.“So few authors have brains enough or literary gift enough to keep their own end up in journalism,”Newman wrote,“that I am tempted to define‘journalism’as‘a term of contempt applied by writers who are not read to writers who are.’”Unfortunately,these critics are virtually forgotten.Neville Cardus,who wrote for the Manchester Guardian from 1917 until shortly before his death in 1975,is now known solely as a writer of essays on the game of cricket.During his lifetime,though,he was also one of England’s foremost classical-music critics,a stylist so widely admired that his Autobiography（1947）became a best-seller.He was knighted in 1967,the first music critic to be so honored.Yet only one of his books is now in print,and his vast body of writings on music is unknown save to specialists.Is there any chance that Cardus’s criticism will enjoy a revival?The prospect seems remote.Journalistic tastes had changed long before his death,and postmodern readers have little use for the richly upholstered Vicwardian prose in which he specialized.Moreover,the amateur tradition in music criticism has been in headlong retreat.25.What would be the best title for the text?
A.Newspapers of the Good Old Days
B.The Lost Horizon in Newspapers
C.Mournful Decline of Journalism
D.Prominent Critics in Memory
