问题     Last December’ s earthquakes in the Iranian city of Bam took a huge death toll—roughly 40,000 people—largely because of the collapse of thousands of mud-brick buildings. If a group of researchers in India are successful, the earthquake might not be as destructive. British and Indian engineers are developing earthquake-proof housing using a cheap, universal material: bamboo.
    They designed a model house built around waterproof bamboo-sheet roofing and bamboo-reinforced concrete walls. To test the structure, the engineers, sponsored by the U. K. Department of International Development, took it to the Earthquake Engineering and Vibration Research Centre in Bangalore, which has a state-of-the-art earthquake simulator(模拟装置). The researchers shook the house with five house with five successive 30-second pulses, being equal to 7. 8 on the Richter(里氏)scale. The simulation was more than 10 times as violent as the Bam earthquake, yet the house emerged undamaged. "We didn’t even crack the paint," says engineer Paul Follett, of Britain’s Timber Research and Development Association.
    By some estimates, more than a billion people already live in bamboo structures. The innovation lies in developing ways to exploit bamboo’ s spring. Easily pre-built, fire resistant, and far lighter than steel, bamboo-based structures could be assembled in three weeks and last 50 years. At five dollars a square foot, they would last roughly half as much as brick-and-block constructions. Follett says the project will follow an " open source" model: " Whatever is developed is freely available for the common good. "
Which of the following are the advantages of bamboos in building houses?
I . Cheap to get.
II. Light to carry.
III. Easy to build.
选项 A、I and II.
B、II and III
C、I ,II And III
D、I and III
答案D
解析 事实细节题。文章最后一段都在介绍竹子的优点，由“Easily pre-built， fire resistant，and far lighter than steel，bamboo—based structures could be assembled in three weeks and last 50 years．”可知，竹子具有容易建造，耐火，比钢结构轻，建造工期 短，使用时间长等特点。另外由第一段最后一句“…using a cheap，universal material： bamboo．”可知，竹子便宜、易得，是建造房子的好材料。故I和Ⅲ正确。而Light to carry(携带方便)并未提到，故选D。
