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？
