Pierre is a 25-year-old penguin at the California Academy of Sciences. Due to his old age, he was going bald, which made him feel too cold to swim in the pool. Therefore, biologists at the academy had a wetsuit created for this penguin to help him get back in the swimming pool.
Unlike marine mammals, which have a layer of fat to keep them warm, penguins depend on their waterproof feathers. Without them, Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19 peers played in the water.
"He was cold; he would shake," said Pam Schaller, a senior biologist. Schaller first tried a heat lamp to keep Pierre warm. Then she got another idea: if wetsuits keep humans warm in the cold Pacific, why not make one for Pierre?
Schaller designed the suit, which covered Pierre’s body and had small openings for his flippers.
“I would walk behind him and look at where there were any gaps, and cut and refit and cut and refit until it looked like it was extremely suitable,” she said.
One concern was that the other penguins would reject Pierre in his new suit, but in fact, they accepted his new look. He swam freely and got along with others well, although he was the only penguin with a black stomach.
Schaller couldn’t say for sure whether the wetsuit allowed Pierre to recover his fine feathers, but “certainly we were able to keep him comfortable during a period of time that would have been very difficult for him to stay comfortable”.
Pierre will take off his suit after his new feathers grow back.

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。
I felt encouraged by his words and began to swim more calmly.But my clothes stuck to me like a heavy weight.I could hardly stay above the surface.
Counsel saw this.“Shall I cut them?”he asked.
With a knife he cut my clothes from top to bottom and took them of quickly while I swam for both of us.
Then I did the same for Counsel,and we continued to swim near each other.
But we were in serious trouble.The crew(船员)might not have noticed our disappearance.
And if they had,they could not return because the rudder(舵)had broken.Counsel thought of all this,and calmly made his plans.We decided to wait for the ship as long as possible,because we had no other hope of safety.I suggested that we save our strength so that both of us would not be tired out at the same time.This was how we did it:While one of us lay on his back,quite still,with arms crossed and legs stretched out(伸直),the other would swim and push him along.We changed every ten minutes or so.In this way we could swim for hours,perhaps till daylight.The crash(破裂声)of the ship and the whale(鲸)had appeared at about eleven o’clock.We had about eight hours to swim before daylight.This seemed possible,if the sea remained calm.
