人生的试金石

  著名的亚历山大图书馆在一次大火中被毁,人们在废墟中发现了残存的一本书。可惜这本书没有什么学术价值,拍卖时,没有人愿意买这本书。最终,一个穷学生以3个铜币的低价购得了这本书。

  这本书不但没有学术价值,内容也枯燥无味。那名穷学生在少有书读的情况下,还是经常把这本书拿出来翻阅。翻到后来,书被翻破了,书脊里掉出了一个小纸条,上面写着试金石的秘密:试金石是能把任何金属变成纯金的一种小鹅卵石,它看起来和其他的鹅卵石没有什么两样,静静地躺在沙滩上,然而,一般的鹅卵石较冷,只有试金石摸起来是温暖的。

  穷学生获知这个秘密后欣喜若狂,立即赶到大海边寻找试金石。穷学生满怀信心地挑选鹅卵石,可是那些石头摸起来都是凉凉的。穷学生渐渐地有些失望了,他愤怒地把捡来的鹅卵石朝大海深处扔去。日复一日,年复一年,他扔鹅卵石的力气越来越大,那些鹅卵石也被越扔越远。

  多年后的一天,穷学生捡到一块温暖的鹅卵石。然而,他已经形成了到手就扔的习惯,当他意识到那是块温暖的鹅卵石时,那块鹅卵石已被他扔到了深海中。他懊恼地潜入海底,寻找了许多天,还是找不到他扔出的那块试金石。

  穷学生终于失望了,他一无所获地回到了首都。当时,国内正在举行建国百年庆典,国王一时开心摆擂台寻找全国力气最大的人。冠军将被封为伯爵,并可获得黄金和良田的赏赐。穷学生想起这么多年来在海边扔鹅卵石的经历,觉得机会来了。穷学生随着众人去看热闹,看来看去,觉得那些人的力气都没有自己的力气大。于是他上台去比试,结果把参赛者一个个打败了,获得了大力士冠军,得到了国王的赏赐。

  穷学生变成了富裕的伯爵,他感谢那本给他带来好运的书,决定把那本书重新装订并保存起来。他拆开书脊以便重新装订,却在书脊里发现了夹藏的另外一张纸条,上面写着:世界上没有真正的试金石,你对人生的态度就是试金石。当你老是抱怨没有机会的时候,或许机会真的到了手边你也把握不了。

1、这篇具有很浓童话色彩的小品文,情节大致可分为五个阶段,下面已概括了首尾两个阶段。请根据文章内容,用短语补写出中间三个阶段的情节。

获知书中秘密→(                     )→(                 )→(               )→重新装订获真谛

填空题

In homes and workplaces around the world it’s hard to find someone who is not celebrating the imminent arrival of football’s World Cup, except for many green activists who are concerned about the environmental impact of the gathering of football’s global tribe.
(41) ______. Even allowing for the fact the study included the impact of transport to and from the World Cup, which Germany didn’t, it still represents a hefty carbon footprint.
In response, the South African authorities have initiated substantial offsetting programs including urban tree-planting, but for local environmental activists that’s not enough.
"Once carbon is produced, claiming that offsetting is ’neutralizing’ the carbon footprint is nothing more than ’greenwash’," Bobby Peek, Friends of the Earth South Africa, told CNN. "Sadly, Friends of the Earth South Africa believes nothing can be done to lessen the carbon footprint, despite the reassurances made by the various cities. "
(42) ______.
"In Durban the construction of an entirely new stadium was not necessary considering that there were two stadiums along side each other which could have been redeveloped rather than one completely demolished to make way for a new construction," he said. "Thus the ’savings made’ were negated by the need for virgin cement. The cement industry is one of the main producers of CO2. For every ton of cement there is one ton of carbon produced. "
(43) ______.
"I think South Africa has missed a trick in not seeking, of its own volition, to host the first ’carbon neutral’ mega-event," Anton Cartwright, co-founder of Promoting Access to Carbon Equity told CNN.
"It would have cost them about $ 25 million had they mobilized a national effort, but this did not happen. Had South Africa spent this money, they would have secured the event’s legacy and kick-started South Africa’s renewable energy and energy efficient sector, and I am not sure there is enough public awareness or political leadership on this issue in South Africa to appreciate quite what an opportunity has been passed up."
(44) ______.
"For the department and South Africa, this is a milestone along the country’s sustainable development growth path," Albi Modise, South African Department of Environmental Affairs, told CNN.
He says that while resources have been tight, there have been 200,000 trees planted in Johannesburg as part of a carbon-offsetting program, 25,000 in Rustenberg, 86,000 in Durban, and a target of 400,000 in Tshwane/Pretoria.
There have also been carbon reduction projects focusing on energy efficiency in street lighting in Durban, Cape Town, Johannesburg, Tshwane, Rustenburg, Polokwane and Port Elizabeth.
Some activists concede there may be some indirect environmental benefits from the World Cup. "(45) ______. In the City of Cape Town transport accounts for almost 50 percent of greenhouse gas emissions, and efforts to reduce this are important. The other important legacy is public awareness— awareness is a prerequisite for the solutions that we so badly need, and what has been most lacking. " said Cartwright.
[A] Peek also claims that there have been unnecessary construction projects using thousands of tons of concrete—one of the most carbon-intensive industries.
[B] Others believe the World Cup is a lost opportunity for South Africa to be a world leader in making sport greener.
[C] One of the most positive legacies will probably come about inadvertently in the form of improved public transport and the bus-rapid-transport system specifically.
[D] Money has been passed from FIFA to national government to host cities, and at the local level not enough is being done in spite of a few brave but small exceptions. Host city efforts have been variable, with a general over-reliance on tree planting.
[E] However, the South African authorities remain adamant they have done all they can with the resources available, although, there is always room for improvement and learning from past mistakes.
[F] A study conducted by the Norwegian government on behalf of the South African authorities estimates the 2010 competition will have a carbon footprint 6 times the size of the last World Cup in Germany.
[G] Cartwright admits that some host cities, most notably Durban and Cape Town, have tried to initiate projects, but says in general it has been left too late.
