And of course I39。d never thought of how they actually got them 39。cos you can39。t imagine having a pine nut farm. So what he said happens is that private firms like his buy a license off the Italian State for the right to go round places like Pompeii archaeological sites and things and systematically collect all the pine cones that e off the trees and similarly in the ... in the forests. Liz: And of course they have to go up the tree because by the time it39。s fallen food isn39。t any good. Sara: That39。s right. They39。re pulling them down and he said they were very good at urn ... recognizing which ones were ready and which ones were a bit hard and etc, and each of them had a sort of stick with a hook at the end which they were using to pull the pines off ... off the trees but clearly it wasn39。t enough to sit around and wait till they fell down. You ... you had to do something about it. There they were. So that was er ... the end of my looking at the ruins for about half an hour. I was too fascinated by this er .. , strange form of er ... agriculture. Liz: Well, what you don39。t intend to see is always the most interesting. Sara: Much more interesting. Exercise Directions: Listen to the dialogue and choose the best answer to each of the following questions. Part 2 PassageWindmills1. Now, windmills are poised to break into a new frontier: the modern city center, often fused into building designs and barely noticeable from a distance. 2. Lighter, quieter, and often more efficient than their rural counterparts, they take advantage of the extreme turbulence and rapid shifts in direction that characterize urban wind patterns. 3. But so far, the current models are being designed more for public or mercial buildings than for private homes, and the smallest weigh roughly 200 kilograms. 4. The recent liberalization of European energy markets also has allowed customers to choose what kind of sustainable energy they want to purchase, with wind energy among the most popular. 5. In the classrooms down below, there39。s no palpable sign that a steel windmill up above is continually feeding kilowatts to the local power grid. The graceful wooden windmills that have broken up the flat Dutch landscape for centuries a national symbol like wooden shoes and tulips yielded long ago to ungainly metalpole wind turbines.* Now, windmills are poised to break into a new frontier: the modem city center, often fused* into building designs and barely noticeable from a distance. Though still in its teething stages, the urban turbine is a hightech windmill designed to generate energy from the rooftops of bustling cities. Lighter, quieter, and often more efficient than their rural counterparts, they take advantage of the extreme turbulence* and rapid shifts in direction that characterize urban wind patterns. Prototypes* have been successfully tested in several Dutch cities, and the city government in the Hague has recently agreed to begin a largescale deployment in 2003. These very visible projects also improve the public profile of wind power, making energy panies look environmentally correct. Current models cost US$8,000 to US$12,000, and can generate between 3,000 and 7,000kilowatt hours of electricity per year. A typical Dutch household uses 3,500 kilowatt hours per year, while in the United States, this figure jumps to around 10,000 kilowatt hours. But so far, they are being designed more for public or mercial buildings than for private homes. The smallest of the current models weigh roughly 200 kilograms and can be installed on a roof in a few hours without using a crane. Germany, Finland and Denmark have also been experimenting with the technology, but the everpractical Dutch are natural pioneers in urban wind power, mainly because of the lack of space there. The Netherlands, with 16 million people crowded into a country twice the size of Slovenia, is the most densely populated in Europe. The scarcity of land also is felt in the countryside, forcing traditional wind farms to seek new locations. Offshore wind farms are more mon, but remain pricey and difficult to service. Various European initiatives to increase the viability* of sustainable energy also have given the urban turbine a boost, leading to heightened interest in zeroenergy buildings that generate their own power. The recent liberalization of European energy markets also has allowed customers to choose what kind of sustainable energy they want to purchase, with wind energy among the most popular. Windmills are usually noisy, though the latest models are considered quiet enough to blend into the background noise that already exists in the urban environment. In the Dutch town of Ede, whose old wooden mill now generates more tourism than energy, the new windmill on the roof of the ROVC Technical School hardly makes a whisper as its blades spin in a brisk winter breeze. If the wind is blowing really hard, you can usually hear it a little bit on the roof. But in the classrooms down below, there39。s no palpable* sign that a steel windmill up above is continually feeding kilowatts to the local power grid. Nor is there the kind of visual blight* often associated with modern windmills.But in the classrooms down below, there’s no palpable sign that a steel windmill up above is cont
