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 ( 安装 ) the specially-designed Pavegen floor tiles (地砖) in America.The tiles use kinetic energy (动能) 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 (反馈信息) 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?
13.What can we learn from the first paragraph?C
A.American students are encouraged to run and jump as much as possible.
B."Going green"means generating less trash or making an attempt to recycle.
C.New York's Riverdale Country School took a different way to go green.
D.New York's Riverdale Country School is the first US school to try new ways to go green.
14.Which of the following statements is TRUE about Laurence Kembell-Cook?A
A.His original motive to invent the Pavegen tiles was to save energy.
B.He believed his invention would be popular with students.
C.He keeps all the technology behind this green tile a secret.
D.He persuaded the school to install Pavegen tiles.
15.Which part of a website is the passage probably taken from?A
A.Science.B.Architecture.
C.Education.D.Agriculture.
分析 本文属于说明文阅读,作者通过这篇文章主要向我们描述了Laurence发明了一种新的节能方式,可以利用人走路跑跳的动能转化为电能提供电力,这种方式不仅环保节能还很有趣,深受大众欢迎.
解答 13.C.细节理解题.根据文章第一段"That's because the school was the first to install ( 安装 ) the specially-designed Pavegen floor tiles (地砖) in America"可知New York's Riverdale Country School首次安装新型地板,可知该校采取了一种新的节能方式;故选C.
14.A.细节理解题.根据文章第四段"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开始在伦敦学校,劳伦斯意识到他的发明不仅节约能源越来越受欢迎,还很有趣,可推测他发明的初衷是节能;故选A.
15.A.推理判断题.通读全文,可知文章讲述的是Laurence发明了一种新的节能方式,深受大众欢迎,既然是发明,应该属于科学类的;故选A.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
