简答题。

     阅读下面短文，根据第1-3小题的具体要求，简要回答问题。

     A barn is where farmers keep animals and equipment. Over time as fewer and fewer people worked

on the land, more and more barns were torn down to make way for developers. Others that remained

might have fallen into poor condition. Or perhaps they just no longer satisfy the needs of modern farmers. Keeping an old barn in good condition might not be seen as worth the cost if it doesn't serve much

purpose. But Americans with historic barns are being urged to save them. The magazine Successful

Farming and the National Trust for Historic Preservation are working together on a program called

Barn Again! The National Trust is a non-profit organization that works to provide protection for places

of historic importance in America.

     The Barn Again program advises hundreds of barn owners every year. Awards are given for the

projects that best succeed in restoring a barn for continued farm use. Winning buildings are used to

demonstrate methods of preservation.

     The organization suggests how problems with things like stone and concrete block foundations can be

fixed. With many old barns, the foundation they are built on is falling apart. Barn Again also offers advice

for other repairs, like how to replace siding and how to use a power washer to remove loose paint. And

farmers are given suggestions about how to calculate costs.

     Leo Fitzpatrick of Beaverton, Michigan won the 2004 Barn Again Award. He made one

improvement at a time. The work took more than nine years. He did it himself, even though for a while he

held another job in addition to farming. He says it cost him fourteen thousand dollars, much less than a

new barn of similar size. The improvements include strengthening the barn. There are no structural

supports inside the building; instead, its sizes hold it up.
