阅读下列短文，根据短文内容选择最佳答案。

①Some days, don’t you think, “Wouldn’t it be nice if the clothes just washed itself?” Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this possible!②A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures (纳米结构) into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and marks that don’t belong on your clothes.③The nanostructures don’t break down the real clothing because cotton and the other clothing materials are too strong to break down. According to CNN, the researchers cover the clothing in a solution made of silver and copper(铜) nanostructures. All it takes is 40 minutes of sunlight and your clothes will look as good as new. ④So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean by the time you go inside. It not only makes your life easier, but it can also be good for the environment.⑤According to the US Department of Energy, washing a piece of clothing uses about25 gallons of water. Water is a very important resource, so using less of it to wash clothes is better for the environment. But one of the scientists at RMIT University knows more needs to be done.⑥“There’s more work to do before we can start throwing out our washing machines,” said Dr Rajesh Ramanathan, “but this is a strong foundation(基础).”So what’s the next step? Ramanathan wants to either start selling the solution by itself or asking clothing makers to treat(处理) the clothing with the solution while clothes are being made.1.
