【題目】
What is the best way to help control air pollution in our towns and cities? Choose public transportation instead of private cars, or reduce the total amount of cars on the street. These can be useful. But here is a more creative way—write a poem.
"I write in praise of air. I was six or five, when a magician opened my fist(拳頭), and I held in my hand the whole of the sky."
Professor Tony Ryan (the science expert) and Professor Simon Armitage(the words expert), from the University of Sheffield, UK, came up with the idea.
But in fact, the poem is not the key part. It is the poster that the poem was written on that plays the biggest part. The poster is 10 meters by 20 meters. It is coated with nanoparticles(納米粒) of titanium dioxide (二氧化鈦). It can absorb the waste from around 20 cars each day if you put it by a busy road. The poster is now displayed on one of the University of Sheffield's buildings.
It doesn't get rid of all the pollutants from traffic, but it will eat up things called nitrogen oxides (氧化氮). These play a part in breathing problems, including asthma(哮喘).
The technology is cheap. "It would add less than 100 to the cost of a poster and would turn advertisements into catalysts(催化劑) in more ways than one," Ryan told the BBC.
He's also working on another idea, which is to add the nanoparticles to washing powder, so that your clothes soak up these poisons while you walk along. And you wouldn't be able to see or feel anything different.
【1】Why can the poem help control air pollution?
A.Because it can warn people of the dangers of pollution.
B.Because the poster that the poem was written on is special.
C.Because it has pictures that explain air pollution.
D.Because Professor Tony Ryan and Professor Simon Armitage are famous.
【2】Which of the following is NOT true of the poster?
A.It is 10 meters by 20 meters.
B.It is coated with nanoparticles.
C.It can absorb the waste from cars.
D.It's widely used in the UK.
【3】From the last two paragraphs, we learn that .
A.the technology costs too much
B.it would make advertisements cheaper
C.washing powder may one day soak up poisons
D.you would feel different wearing the clothes
