Question

【題目】根據(jù)短文內(nèi)容，選擇最佳答案。 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 (納米結(jié)構(gòu)) into clothing, which can then clean the clothes. When sunlight hits the nanostructures, they break down the dirt and stains (污漬) 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 (銅) 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 (基礎(chǔ)).”
So what's the next step? Ramanathan wants to either start selling the solution by itself or convincing (說服) 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】文章大意：這篇短文主要介紹了澳大利亞研究人員找到了一種能讓衣服自潔的方法。通過這種方法不僅能使人們生活更安逸而且還會節(jié)約水資源。
（1）細(xì)節(jié)理解題。根據(jù)When sunlight hits the nanostructures, they break down the dirt and stains that don't belong on your clothes.故選C。
（2）歸納理解題。根據(jù)短文的第四段主要描述的是自潔性的衣服能使生活簡易，第五段主要描述自潔性衣服能節(jié)約水資源，所以四五段主要描述的是自潔性衣服的優(yōu)點(diǎn)，故選A。
（3）詞義猜測題。根據(jù)上下文可知不是指機(jī)器，銀，而是指和衣服相關(guān)解決方案，即設(shè)計(jì)，故選D。
（4）推理判斷題。根據(jù)短文最后兩段可以推斷這種衣服還沒有投入使用，故選B。
