1、阅读理解专练(八)(限时30分钟)ARamen noodles have been a go-to(首选的)food for students for decades. After all, they only take eight minutes to cook in a dorm hotpot and are easy on the budget. Holly Grounds, a recent project design graduate of Ravensbourne University, in London, used to eat a lot of ramen noodles
2、when she studied. But it got her thinking that the packaging of a product that takes just minutes to cook and eat shouldnt take decades or more to decompose(分解). Thats why she decided to make eatable wrappers for noodles, avoiding the need for plastic. Grounds wanted to produce a product that the us
3、er could watch actually dissolve in the pot, unlike other bio-based films(包装膜)that are being developed. “While other bio-based alternatives to plastic claim to be compostable(可用作堆肥的), from a consumer perspective its not always that simple, ”she said. “Many of the emerging bio-based films only break
4、down in an industrial composter(堆肥机)at 50 degrees Celsius, so they often end up in the wrong place without the consumer really knowing that they caused damage to the planet. ”Now, instead of plastic packs of seasonings(调料), the dried spices and flavorings are part of a flavorless bioplastic film tha
5、t wraps the noodles and keeps them fresh. The film dissolves in less than a minute when it comes into contact with boiling water, according to Grounds, and the liquid becomes the sauce for the noodles and larger ingredients like dried shrimp. “The ingredients are blended and heated until the mixture
6、 is thick enough. At this point, I add the spices and flavorings before pouring it into a mold to set for 24 hours, ”Grounds said. These noodle parcels are then packaged in a wax-coated paper. With plastics taking hundreds of years to decompose and filling landfills and oceans globally, eatable pack

But a woman Mya Le Thai may have found
13、the answer to this problem. Thai was frustrated that the batteries for her wireless devices degraded(降级)over time, until they failed to charge fully. She did not like having to keep her laptop connected to an electrical outlet to keep it powered on. So, she decided to do something about that problem
14、. At first, she and her team at UC Irvine thought about inventing a new battery. But as they experimented, Thai discovered something that might permit lithium-ion(锂离子)batteries to last forever. Lithium-ion batteries power most wireless devices. Over time, the batteries lose the ability to hold a cha
15、rge. Most of these batteries have a life span of about 7, 000 charging cycles before they die. One of the reasons lithium-ion batteries degrade is their use of nanowires to carry electricity. Nanowires are extremely thin. A human hair is thousands of times thicker, for example. Nanowires are extreme
16、ly efficient carriers of electricity, which makes them useful in batteries. But, Thai had a theorythe nanowires might last longer if covered with a gel(凝胶). She and her team tested this theory. “It was a long process and a lot of work, ”Thai said. The team tried many coverings for the wires. PMMA, a
17、 type of plastic, was one of them. The nanowires were coated with PMMA and cycled through charges 200, 000 times. The PMMA-coated nanowires showed no evidence of damage. The results suggest that batteries could last forever, without losing charging ability. Thai hopes to continue her research to und
18、erstand why this gel works so well and to see if any other gel could create better results and she is enjoying the publicity about her discovery. She said she never expected her research to get media coverage. “Its kind of cool”, she said. “Im really glad people are showing interest in my work and n
