根据短文内容,选择最佳答案。

    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 possible!

    A 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 stains (污渍) that don't belong on your clothes.

    The nanostructures don't break down the actual clothing because cotton and the other clothing materials are too strong to be broken 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.

    So 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.

    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 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.

    “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 convincing (说服) clothing makers to treat the clothing with the solution while clothes are being made.

阅读下面的文言文,完成问题。

    栾布者,梁人也。始梁王彭越为家人时,尝与布游。穷困,赁佣于齐,为酒人保。数岁,彭越去,之巨野中为盗,而布为人所略卖为奴于燕。为其家主报仇,燕将臧荼举以为都尉。臧荼后为燕王,以布为将。及臧荼反汉击燕虏布梁王彭越闻之乃言上请赎布以为梁大夫。

    使于齐,未还,汉召彭越,责以谋反,夷三族。已而枭彭越头于洛阳下,诏曰:“有敢收视者,辄捕之。”布从齐还,奏事彭越头下,祠而哭之。吏捕布以闻。上召布,骂曰:“若与彭越反邪?吾禁人 勿收,若独祠而哭之,与越反明矣。趣烹之。”方提趣汤,布顾曰:“愿一言而死。”上曰:“何言?”布曰:“方上之困于彭城,败荥阳、成皋间,项王所以遂不能西,徒以彭王居梁地,与汉合从苦楚也。当是之时,彭王一顾,与楚则汉破,与汉而楚破。且垓下之会,微彭王,项氏不亡。天下已定,彭王剖符受封,亦欲之万世。今陛下一征兵于梁,彭王病不行,而陛下疑以为反,反形未见,以苛小案诛灭之,臣恐功臣人人自危也。今彭王已死,臣生不如死,请就烹。”于是上乃释布罪,拜为都尉。

    孝文时,为燕相,至将军。布乃称曰:“穷困不能辱身下志,非人也!富贵不能快意,非贤也。”于是尝有德者厚报之,有怨者必以法灭之。吴、楚之乱,以军功封俞侯,复为燕相。燕齐之间皆为栾布立社,号曰栾公社。

    景帝中五年薨。子贲嗣,为太常,牺牲不如令,国除。

    太史公曰:“栾布哭彭越,趣汤如归者,彼诚知所处,不自重其死。虽往古烈士,何以加哉!”

(《史记•季布栾布列传》)
