Question

【题目】【2016山东泰安中考】阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

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.

【1】 How do the clothing with the nanostructures get cleaned?

A. Cotton clothes wash easily

B. This kind of clothing washes it by itself.

C. The dirt and stains are broken down in the sunlight.

D. Silver and copper help to get off the dirt in the dark.

【2】 What do Paragraphs 4-5 talk about?

A. What advantages the self-cleaning clothes have.

B. How the self-cleaning clothes work.

C. How the self-cleaning clothes are made.

D. What helps the self-cleaning clothes work.

【3】What does the underlined word “solution”in the last paragraph mean?

A. Machines B. Clothes.

C. Silver. D. Design.

【4】What can we learn from the passage?

A. Silver and copper sell well.

B. The solution is not put into practice.

C. Clothing makes certainly like the solution.

D. We don’t need washing machines any more.

Answer 1

【答案】

【1】C

【2】A

【3】D

【4】B

【解析】

试题分析：这篇短文主要介绍了澳大利亚研究人员找到了一种能让衣服自洁的方法。通过这种方法不仅能使人们生活更安逸而且还会节约水资源。

【1】C细节理解题。根据When sunlight hits the nanostructures, they break down the dirt and stains that don’t belong on your clothes.故选C。

【2】A归纳理解题。根据短文的第四段主要描述的是自洁性的衣服能使生活简易，第五段主要描述自洁性衣服能节约水资源，所以四五段主要描述的是自洁性衣服的优点，故选A。

【3】D词义猜测题。根据上下文可知不是指机器，银，而是指和衣服相关解决方案，即设计，故选D。

【4】B推理判断题。根据短文最后两段可以推断这种衣服还没有投入使用，故选B。
