9.Imagine being a crew member,hundreds of years ago,sailing in southern waters.Your captain is searching for food while exploring unfamiliar waters.Your job is to watch the sea off the ship's side for ice.The wind is cold on your face.Alongside the ship,a fish darts past.Another slows to a stop and raises its head above the water to look at you.How could a fish do that?
Did the sailors see fish with feathers or swimming birds?Today,we know that the sailors saw birds that developed the ability to swim.Their wings became flippers,and they could"fly"through the water with amazing speed.
There are many types of penguins.Only two kinds raise their young on the continent of Antarctic.Adelie penguins grow up to 29inches tall and have a white ring around each eye.Emperor penguins have yellow orange color near their necks.Standing about 35inches tall,they are the tallest penguins living today.
Emperor penguins have nests on top of their feet.Father Emperor penguins keep the egg on top of their feet for more than two months,until the egg is ready to hatch.The mother penguin goes out for food during that time.Imagine holding an egg on your feet for two months until someone returns with food!
Male and female penguins are both good parents.Once the chicks hatch,both parents travel long distances to find food for them in the sea.It may be days before the parents return and the chicks eat again.When they return with food,the fun really begins.Chicks chase their parents,begging for food.Penguin chicks eat huge amounts at one time.
Eventually,the adult penguins stop feeding the chicks.This is nature's way of forcing children to grow up.When the penguin chicks are hungry enough,they find their way to the sea.Without any swimming lessons,they make their way into the icy waters and swim as only penguins do.

分析 文章描述了企鹅的发展演变、外貌、生活习性、哺育后代等内容,让我们更多地了解企鹅.
解答 29.C 推理判断题.根据作者第一段对当时场景的描述"Did the sailors see fish with feathers or swimming birds?(水手看到带羽毛的鱼或者会游泳的鸟了吗?)"可知,当第一次看到企鹅时感觉不同寻常,认为企鹅是会游泳的鸟,故选C.
30.B 细节理解题.根据第二段中"we know that the sailors saw birds that developed the ability to swim.Their wings became flippers,and they could"fly"through the water with amazing speed."和对企鹅的描述可知,几百年前见到的企鹅是学会了游泳的鸟,故选B.
31.B 推理判断题.根据下面的描述"When they return with food,the fun really begins.Chicks chase their parents,begging for food.Penguin chicks eat huge amounts at one time."可知,父母觅食回来后,小企鹅追着父母要吃的特别有意思,故选B.
32.C 细节理解题.根据最后一段"This is nature's way of forcing children to grow up.When the penguin chicks are hungry enough,they find their way to the sea."可知,等小企鹅稍大点父母就不再喂它,强迫它自己去觅食,这是自然生存法则,故选C.
