15.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 (潜水服)created for this penguin to help him get back in the swimming pool.Unlike marine(海洋的)mammals,which have a layer of blubber to keep them warm,penguins depen 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 19peers 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.

分析 人们印象中,企鹅应该不怕冷.而生活在美国加利福尼亚州旧金山加州科学院水族馆的一只斑嘴环企鹅,由于羽毛脱落而无法忍受冰冷的池水.为此,加州科学院研究人员特地为这只企鹅穿上"防寒服",让它能够与同伴一样在水中游泳嬉戏.
解答 48.B.细节理解题.文章第一段Due to his old age,he was goingbald,which made him feel too cold to swim in the pool说明了Pierre怕冷的原因是年纪大了几乎没有羽毛;故选B.
49.B.细节理解题.文章第五段Iwould walk behind him and look at where there were any gaps,and cut and refitand cut and refit until it looked like it was extremely suitable说明了Pam跟踪Pierre的原因是看潜泳衣是否有需要改装的地方;故选B.
50.C.词义猜测题.根据第二段Without them,Pierre was unwilling to jump into the swimming pool and ended up trembling on the side of the pool while his 19peers played in the water可知没有羽毛,彼埃尔不愿意跳进游泳池,在泳池边颤抖;意为颤抖;故选C.
51.A.主旨大意题.根据第一段Therefore,biologists at the academy had a wetsuit (潜水服)created for this penguin to help him get back in the swimming pool可知全篇讲述的是生物学家给一只老企鹅做保暖夹克,帮它重返泳池的故事.因此A项正确.
点评 考察学生的细节理解和推理判断能力,做细节理解题时一定要找到文章中的原句,和题干进行比较,再做出正确的选择.在做推理判断题不要以个人的主观想象代替文章的事实,要根据文章事实进行合乎逻辑的推理判断.
