Question

Some days, don't you think, "Wouldn't it be nice if the laundry would just do itself?" Self-cleaning clothes may sound crazy. But Australian researchers have found a way to make something like this _______!

A team at RMIT University in Melbourne, Australia, found a way to put special nanostructures (納米結(jié)構(gòu)) into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down dirt. The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be _______.

According to CNN, the researchers covered the clothing in a solution made of silver and copper (銅) nanostructures. _______ it takes is 40 minutes of sunlight and your clothes will look as good as new.

So if you spill on yourself during lunch, you can step outside for a walk, and it will be clean _______ the time you go inside. It not only makes your life easier, but can also be good for the climate.

According to the US Department of Energy, the average load of laundry uses about 25 gallons (about 94 liters) of water. Water is a very important resource, so using _______ of it to wash clothes is better for the environment. So one of the scientists at RMIT University knows more needs to be done.

"There's more work to do before we can start _______ our washing machines," said DiRajesh Ramanathan, "but this is a strong foundation (基礎(chǔ))."

So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing clothing makers to treat their clothing with the solution.
