听力原文： Welcome to the Four Winds Historical Farm, where traditions of the past are preserved for visitors like you. Today giving this barn behind me a sturdy thatched roof able to , withstand heavy winds and last up to a hundred years．How do they do it？ Well，in a nutshell，thatching involves covering the beams'or rafters—the wooden skeleton of a roof—with reeds or straw．Our thatchers here have harvested their own natural materials for the job—the bundles of water reeds you see lying over there beside the barn．
Thatching is certainly uncommon in the United States today．I guess that's why so many of you have come to see this demonstration．But it wasn't always that way．In the seventeenth century, the colonists here thatched their roofs with reeds and straw, just as they had done in England. After a while, though, they began to replace the thatch with wooden shingles because wood was so plentiful. And eventually, other roofing materials like stones, slates, and clay tiles came into use.
It's a real shame that most people today don't realize how strong and long-lasting a thatched roof is. In Ireland, where thatching is still practiced, the roofs can survive winds of up to one hundred ten miles per hour. That's because straw and reeds are so flexible. They bend but don't break in the wind like other materials can. Another advantage is that the roofs keep the house cool in the summer and warm in the winter. And then, of course, there's the roofs' longevity--the average is sixty years, but they can last up to a hundred. With all these reasons to start thatching roofs again, wouldn't it be wonderful to see this disappearing craft return to popularity？

The Lure of a Big City Vacation
[From the Tower of London to Paris' Eiffel Tower, historic landmarks and one-of-a-kind attractions have long lured travelers to the world's great cities.]
"It becomes, at least for some people, a kind of pilgrimage in the sense that you want to finally see the Statue of Liberty and it's in New York and you have to go to New York to see it," said Witold Rybczynski, a professor of urbanism at The Wharton School of the University of Pennsylvania.
"There isn't a second version of it anywhere else."
This sort of unique attraction, combined with the excitement d city life and a concentration of cultural opportunities, fine dining, shopping and accommodations brings some visitors back again and again.
"There's such a vast range of riches in a small, pretty easily navigated space. That's definitely what attracts me to cities," said Don George, global travel editor for Lonely Planet Publications.
Few large cities have remarkable natural scenic attractions to build upon, so they tend to rely on heritage and cultural sites to set themselves apart, according to Douglas Frechtling, a professor of tourism studies at George Washington University.
Visiting cities gained popularity in the 18th and 19th centuries, as the landed aristocracy in Britain increasingly sent their sons — and occasionally their daughters — to round out their education on a Grand Tour of the celebrated sights and cities of continental Europe, Frechtling said. America's nouveau riche adopted this tradition in the late 19th and early 20th centuries, and later, less well-heeled travelers joined the tourist ranks.
"In terms of what we might call mass tourism or middle-class tourism, that really didn't develop until after World War II," Frechtling said. "It was just too difficult and too expensive to travel."
Navigation 101
Now the allure of big cities seems as potent as ever. The number of visitors to central Paris in 2004, for example, is estimated at 25 million, according to the Paris convention and Visitors Bureau.
New York City welcomed 39.9 million visitors to the five boroughs in 2004 and is expecting a tally of nearly 41 million for 2005, according to NYC & Company, the city's official tourism marketing organization.
Getting acclimated to the pace and logistics of a large metropolitan area can take a little time.
"I recommend when you get somewhere, you either ask a taxi driver to take you around or you get on one of the tourist buses that allow you to pay a one-day fee and travel in the circuit as often as you want, so that you get a visual idea of the city," said Ruth Jarvis, series editor for Time Out Guides, in a phone interview from her London office.
Whether you're visiting a big city for the first or 15th time, a good map is essential. Even locals carry maps to navigate London, Jarvis said, so there's no shame in standing on a street comer peering at yours.
In some cities, local volunteer guides will help guests discover the destination, Jarvis said. In New York, Big Apple Greeters offers this service.
Jarvis recommends walking as much as possible because it gives you more opportunities to discover the local culture and get a sense of a city's layout. When using public transportation, Jarvis suggests taking buses over subways for the same reason. "If you're just a little bolder and you get buses, then you're above ground and you can pick up where you are so you have the confidence to make your own explorations a little later."
Most cities offer discount transportation cards that can save you motley if you anticipate frequent bus or subway trips. Keep your hotel's address on hand and have the hotel give you the number of a reputable cab company to keep with you, Jarvis suggests. Renting a cell phone in an international de
