Article: 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 ( ) the specially-designed Pavegen floor tiles in America. The tiles use kinetic energy 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 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 30 seconds. 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? Question: Which of the following statements is TRUE about Laurence Kembell-Cook? Options: 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.

The most popular type of Eurail Pass amongst young people, according to Zhao Jiaji, from China Air Service Ltd, is the Eurail Selectpasses. With this you can design your own trip by selecting three, four or five neighbouring countries from a total 18 nations including Liechtenstein, Monaco, Hungary and Romania. "There is plenty of choice with this pass: in total this range offers over 400 different combinations of countries to choose from!" said Zhao. The Eurail Selectpass gives 5 to 10 travel days within a 2-month period. For more flexibility there are the Eurail Passes which allow you to take trains in 17 countries on any day you like. It is valid for a period of either 15 or 21 days, one, two or three months. If you just want to travel in one or two countries to learn more about the local culture, Eurail Pass also offers two-country passes such as Spain-Portugal, France-Switzerland and Belgium-Luxemburg. And countries like Britain, France and Germany offer a kind of Eurail Pass which allows unlimited train travel in their country. Before buying the Eurail Pass, you should know some tips to save money. The 2nd class train travel ticket is cheaper than 1st class. And youths under 26 years old or groups of 2 or more people traveling together can enjoy discounts. For more information, please check out...
