Passage Three
There is a tale that straw is the worst material from which to build a house, particularly if you are a pig with a hungry wolf around. So the cards were stacked against Warren Brush when local officials learned that he had several buildings made of straw bales ( 大捆 ) on his land.
They have tried to fine him a lot. But the case is still unresolved. The problem is that California's building codes make no provision for the use of straw. And Mr Brush has many defenders--among them several university scientists and David Eisenberg, the chairman of the United States Green Building Council's code connnittee. They would like to see the prejudice against straw houses eliminated, for straw is, in many ways, an ideal building material.
It is, for one thing, a great insulator (绝缘体). That keeps down the heating bills in houses made from it. It is also a waste product that would otherwise be burned, and is therefore cheap, and very much to the point in a place like California, it is earthquake-resistant. Last year a test conducted at the University of Nevada showed that straw-bale constructions could' withstand twice the amount of ground motion recorded in the Northridge earthquake that hit LosAngeles in 1994.
There are other straws in the wind: a post office in suburban Albuquerque, a school in Maryland, and an office complex in suburban Los Angeles have all been built from straw. Even California is having a rethink, and may change its rules to adapt to straw-bale construction. As Mr Eisenberg observes, "the lesson of the Three Little Pigs isn't to avoid straw. It's that you don't let a pig build your house."
What is Paragraph 3 mainly about?
A、 The structure of straw houses.
B、 The possibility of building straw houses.
C、 The suggestions for building straw houses.
