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 (纳米结构) 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 (铜) 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 (基础)."

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.

【解析】

文章主要介绍了科学家们研究如何让衣服可以自我清洁。

1.

句意：但是澳大利亚的研究人员已经找到了一种方法，可以让这样的事情成为可能。

考查动词辨析。true 事实；possible可能；close靠近；special 特别。根据“But Australian researchers have found a way to make something like this_______！”，可知是讲但是澳大利亚的研究人员已经找到了一种方法，可以让这样的事情成为可能，故选B。

2.

句意：纳米结构不会破坏衣物，因为棉花和其他衣物材料都很坚固，不会被破坏。

考查动词辨析。destroyed毁灭；divided划分；broken打破；damaged损坏。根据“The nanostructures don't break down the actual clothing”纳米结构不会破坏衣物，可知此处讲因为棉花和其他衣物材料都很坚固，不会被破坏，故选C。

3.

句意：它所需要的只是晒40分钟的阳光，你的衣服就会像新的一样。

考查代词辨析。All所有；Everything每件事；Something一些事；This这是。根据“the researchers covered the clothing in a solution made of silver and copper nanostructures”研究人员将衣服浸泡在由银和铜纳米结构制成的溶液中。可知此处是讲所有的只需要晒40分钟的阳光，你的衣服就会像新的一样，all指代所有的时间，故选A。

4.

句意：所以，如果你在午餐时溅到自己身上，你可以走出去散散步，到你进去的时候它就会干净了。

考查介词。for 为了；as作为；by通过；with和。根据“the time you go inside”，可知是讲等你进去的时候，它就干净了，by the time ……的时候，固定搭配，符合语境，故选C。

5.

句意：水是一种非常重要的资源，所以少用它来洗衣服对环境更有利。

考查副词。more 更多；most最多；fewer更少；less最少。根据“Water is a very important resource”，可知此处是讲：水是一种非常重要的资源，所以用更少的水来洗衣服对环境更好，故选D。

6.

句意：在我们开始扔掉洗衣机之前还有更多的工作要做。

考查动词短语。putting down放下；working on解决；throwing away扔掉；dealing with处理。根据“There's more work to do”，可知是讲在我们开始扔掉洗衣机之前还有很多工作要做，故选C。
