19.At most schools,"going green"means generating less trash or making an attempt to recycle.But at New York's Riverdale Country School,it means being encouraged to run and even jump in the hallway.That's because the school was the first to install ( 安裝 ) the specially-designed Pavegen floor tiles (地磚) in America.
The tiles use kinetic energy (動能) expanded by the kids and transform it into electricity that can be used to power classroom lights,science projects and charge electronic devices.The first US installation of Pavegen tiles near the school's student center is thanks to 14-year-old Zach Halem,who managed to convince the officials to purchase them.
Besides providing fun green energy,the tiles also serve as a learning tool.Every time a student steps on one,a brightly-lit LED board provides instant feedback (反饋信息) on how much energy was generated.Depending on the force,every step results in between one to seven watts-enough power to light an LED street lamp for about 30seconds.
Made largely from rubber and other recycled materials the tiles are invented by the 26-year-old British industrial designer Laurence Kembell-Cook.While new to the US,they have been installed in numerous places in Europe,ranging from a London underground station to a marathon track in Paris.However,it was not until Pavegen started getting popular in London schools that Laurence realized that his invention not only saved energy,but was also fun!
Though the young inventor will not give too many details about the technology behind this green tile,he says that it is very different from other kinetic energy harvesting systems.
Whatever the secret,let's hope more US schools decide to install these fun tiles.In fact,why stop at schools?These tiles could be installed everywhere,from sidewalks to homes.Then we could all be"green"and have fun!Who knew that was even possible?

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Laurence發(fā)明了一種新的節(jié)能方式,可以利用人走路跑跳的動能轉(zhuǎn)化為電能提供電力,這種方式不僅環(huán)保節(jié)能還很有趣,深受大眾歡迎.
解答 13.C.細節(jié)理解題.根據(jù)文章第一段"That's because the school was the first to install ( 安裝 ) the specially-designed Pavegen floor tiles (地磚) in America"可知New York's Riverdale Country School首次安裝新型地板,可知該校采取了一種新的節(jié)能方式;故選C.
14.A.細節(jié)理解題.根據(jù)文章第四段"it was not until Pavegen started getting popular in London schools that Laurence realized that his invention not only saved energy,but was also fun!"可知直到Pavegen開始在倫敦學(xué)校,勞倫斯意識到他的發(fā)明不僅節(jié)約能源越來越受歡迎,還很有趣,可推測他發(fā)明的初衷是節(jié)能;故選A.
15.A.推理判斷題.通讀全文,可知文章講述的是Laurence發(fā)明了一種新的節(jié)能方式,深受大眾歡迎,既然是發(fā)明,應(yīng)該屬于科學(xué)類的;故選A.
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.
