5、knesses tailored to specific sound requirements. Most of these foams, however, are made from a type of plastic material and other chemical substances that are obtained from natural oil or petrol. To avoid petrochemicals, researchers have explored more renewable sources and biodegradable sound-absorb
6、ing alternatives. But many current options are made from plant fibers that dont effectively decrease noises in the most useful range of sound frequencies, or they are too thick or difficult to produce. So, Chindams team wanted to develop a biodegradable material from a plant, which would be simple t

After running the materials through a battery of tests, the researchers measured how well the f
8、ilms reduced sound across a range of frequencies. To do this, the team created a sound tube in which a speaker is placed at one end, and the test film is fitted over the other end. Microphones in the middle of the tube measured the amount of sound sent by the speaker and the amount of sound reflecte

These experiments showed that the films with many small holes made with the highest concentrations of agar had the greatest sound-absorbing qualities and performed similarly to traditional sound-absorbing foams. The researchers plan to explore ways to change the agar films to give th

13、 SoundsC. A Tube fbr Measuring the Amount of Underwater SoundsD. Seaweed: a Better Sound-absorbing Underwater Plant【答案】12.D13. A 14. B 15. A【解析】【导语】这是一篇说明文。现在,研究人员在ACS可持续化学与工程杂志上报告称,他们从海藻中提 取了种可生物降解的薄膜,可以有效地吸收这一范围内的声音。文章介绍了泡沫塑料的缺点以及这种环 保吸音材料的开发过程。【12题详解】细节理解题。根据第一段中“But most of the sound-absorbing m
14、aterials that can cancel out human voices, traffic noise and music are made from plastic foams (泡沫)that arent easily recycled or degraded.(但大多数能消除人声、 交通噪音和音乐的吸音材料都是由不易回收或降解的泡沫塑料制成的)”可知,泡沫塑料的缺点是它们难以 实现可持续利用。故选D。【13题详解】细节理解题。根据第二段中 “ So, Chindams team wanted to develop a biodegradable material from a
15、plant, which would be simple to produce and could absorb a range of sounds.(所以,Chindam 的团队想要从植物中开发出一 种可生物降解的材料,这种材料生产简单,可以吸收一系列的声音)”可知,Chindam的团队会开发很容易 就能得到的吸音材料。故选A。【14题详解】主旨大意题。根据最后段“Theleam created films of agar (琼脂),a material that comes from seaweed, along with other additives developed from pl
