2．In the heart of Tokyo，a skyscraper，the Grand Prince Hotel Akasaka，is being demolished（拆除）．But there are no explosives in sight．Instead，all that can be seen is the roof slowly sinking as the building shrinks beneath it．
The Demolition is being carried out by the Taisei Corporation，which has developed what it claims is a cleaner and more environmentally friendly way to tear down high-rises．Called the Taisei Ecological Reproduction System，it works from the top down，breaking a building apart floor by floor．The once 140-metre tall hotel is now missing its top 30meters and by May it will disappear．The levels being pulled down are sealed within an enclosure that wraps around the building，while huge jacks（千斤頂 ）slowly lower the original roof down as floors are removed．Fully enclosing（ 圍 住 ）the demolition area reduces the dust emitted（散出）from the site compared with conventional methods，say Taisei's Hideki Ichihara．
Before the demolition begins，all non-structural elements of the building are removed by hand．Workers then take out beams（橫梁）and concrete flooring．By recycling building materials and getting rid of heavy machinery that runs on fossil fuels（礦物燃料），Ichihara says，the process reduces carbon dioxide emissions by as much as 85percent．"In Japan alone there are 797skyscrapers over 100meters tall，around 150of which will be between 30and 40years old in the next decade，"says Ichihara．This has historically been the age when such buildings are arranged for demolition，but conventional methods are not suitable for such tall skyscrapers．Taisei and its competitors Kajima and Takenaka Corporations need to develop new demolition systems．Kajima's"cut and down"method removes floors from the ground up，while Takenaka's approach is almost the same as Taisei's．
After Tokyo was shaken by earthquakes in March 2011，the billionaire Akira Mori called for the country to stop building skyscrapers over 100meters high．Instead he suggested lower，wider-based structures should be built．Takuro Yoshida，a professor at Kogakuin University in Tokyo，argues that newer engineering techniques could keep buildings safely standing for longer periods．"The idea that buildings are rebuilt on a 30-to 40-year cycle is itself about 20years old，"he says，adding that the ecological benefits of demolition．

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了一個更清潔，更環(huán)保的方式拆除摩天大樓，新拆遷有些工作必須手工完成．
解答 33．C．細節(jié)理解題．根據(jù)第三段：Before the demolition begins，all non-structural elements of the building are removed by hand可知新拆遷有些工作必須手工完成；故選C．
34．B．推理判斷題．根據(jù)第三段：Kajima's"cut and down"method removes floors from the ground up，while Takenaka's approach is almost the same as Taisei's可知kajima的拆除方法不同于Takenaka的；故選B．
35．C．主旨大意題．根據(jù)第二段：The Demolition is being carried out by the Taisei Corporation，which has developed what it claims is a cleaner and more environmentally friendly way to tear down high-rises可知主要講一個更清潔，更環(huán)保的方式拆除摩天大樓；故選C．
點評 考察學(xué)生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
