Common indoor plants may prove to be a valuable weapon in the fight against rising levels of indoor air pollution. Those plants in your office or home are not only decorative, but NASA scientists are finding them to be surprisingly useful in absorbing potentially harmful gases and cleaning the air inside modern buildings.
NASA and the Associated Landscape Contractors of America(ALCA)have announced the findings of a 2-year study that suggest the common indoor plant may provide a natural way of helping combat "Sick Building Syndrome."
Research into the use of biological processes as a means of solving environmental problems, both on Earth and in space habitats, has been carried out for many years by Dr. Bill Wolverton, formerly a senior research scientist at NASA’ s John C. Stennis Space Centre, Bay St. Louis, Miss.
Based on preliminary evaluations of the use of common indoor plants for indoor air purification and revitalization, ALCA joined NASA to fund a study using about a dozen popular varieties of ornamental plants to determine their effectiveness in removing several key pollutants associated with indoor air pollution. NASA research on indoor plants has found that living plants are so efficient at absorbing contaminants in the air that some will be launched into space as part of the biological life support system aboard future orbiting space stations.
While more research is needed, Wolverton says the study has shown that common indoor landscaping plants can remove certain pollutants from the indoor environment. "We feel that future results will provide an even stronger argument that common indoor landscaping plants can be a very effective part of a system used to provide pollution free homes and work places" he concludes.
"Plants take substances out of the air through the tiny openings in their leaves," Wolverton said. "But research in our laboratories has determined that plant leaves, roots and soil bacteria are all important in removing trace levels of toxic vapours."
"Combining nature with technology can increase the effectiveness of plants in removing air pollutants," he said. "A living air cleaner is created by combining activated carbon with a potted plant. The roots of the plant grow right in the carbon and slowly
degrade
the chemicals absorbed there," Wolverton explains.
NASA research has consistently shown that living, green and flowering plants can remove several toxic chemicals from the air in building interiors. You can use plants in your home or office to improve the quality of the air to make it a more pleasant place to live and work—where people feel better, perform better, and enjoy life more. [br] The word "degrade"(Line 4, Para. 7)may be replaced by______.
选项
A、reduce
B、increase
C、neutralize
D、replace
答案
A
解析
语义题。原文第七段大意为:“把自然和技术结合起来能够增强植物清除空气污染物的效力,”他说。“把活性炭和盆栽植物结合在一起,一个活的空气清洁器就诞生了。植物的根就长在活性炭中,在那儿慢慢地将吸收的化学物质 ,”沃尔弗顿解释说。联系前一句内容,推断degrade应和remove意思相同,为“降低,降解”.A选项reduce接近,因此选A。
