Emperor penguins are the largest penguins on Earth. Each adult is over a metre tall, and can weigh up to 40 kilograms.

For many months each year, emperors live near the sea in large groups called colonies. However, in May, the weather gets colder and ice covers large areas of ocean. Each colony moves many kilomtres from the water.

Sharing the work

There, each mother penguin lays just one egg. Then all the hungry mothers must walk back to the ocean to find food. The father penguins put their eggs on top of the feet, under a special piece of skin called the brood pouch. For two months, the father penguins keep the eggs safe and warm. Antarctica. Most animals leave for warmer places, but the father penguins stay. In this time, without food, a father penguin can lose almost half of his weight.

New life

Then the babies begin to hatch! The mother penguin returns just in time to see her baby come out of its egg. The chick is then moved to her brood pouch. This can be difficult. If the chick falls, it can freeze quickly, so the penguin parents must be very careful! Once this is done, the father penguin can go back to the ocean to find food.

Growing up

Over the next few months, penguin parents take turns to go to the ocean for food. They each make the trip several times, bringing back food for the chick. The chick grows quickly and is always hungry.

Into the water

By December, winter is ending. The chick is five months old and can live on its own. Soon it enters the water for the first time. It will swim and eat until next April, and then return here. After a few more years, it, too, will start its own family.

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(拳头), 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(纳米粒) of titanium dioxide (二氧化钛). 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(催化剂) 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
