题目内容
20.This September the 2014winners of the Ig Nobel awards came out!Research into why bananas are slippery(滑的) won the Ig Nobel for physics.
A team of scientists from Japan,tested 12different banana skins.They then used sensors to measure the friction(摩擦力) between the slippery side of"Banana skin"banana skin and the ground.They found that when someone steps on a banana skin,a special chemical,polysaccharide follicular gel(囊泡多糖凝胶),is set off.This chemical reduces friction by one-fifth.Later,scientists also compared banana skin with apple skin and orange skin and showed why apple and orange skins are not quite so dangerous.Friction was about 60per cent higher on an apple peel.
Polysaccharide follicular gel is also found in the membranes (薄膜) where our bones meet."This idea will help to design a joint prosthesis (人工关节),"Kiyoshi Mabuchi,the lead scientist,told the BBC news.
The Ig Nobel Prize in Medicine went to doctors from the Detroit Medical Center,US.They used salt pork to stop a young child's nose bleed.Other interesting research includes whether owning a cat was bad for your mental health and looking at ugly art can be painful.
While Ig Nobel Prizes are mostly funny,great scientific breakthroughs(突破) can be made.In 2006,a team found that a type of mosquito(蚊子) is equally attracted to the smell of feet and cheese.As a result,mosquito traps were made using cheese to fight against malaria in Africa.

A.chemistry B.Science C.medical research D.Arts

As we know,stone is easy to get on the earth,so it's cheap.And the stone paper is about 20% to 30% cheaper than ordinary paper.The stone paper causes little pollution and helps protect the environment,because it makes tree and water free.The following table shows what is needed to make one ton of stone paper and one ton of ordinary paper.
| Trees | Water | Bleach (漂白剂) | Stone | Additives (添加剂) | |
| Stone paper | No | No | No | 0.8ton | 0.2ton |
| Ordinary paper | 5tons | 72M3 | Yes | 0.2-0.3ton | 0 |
