A penguin (企鹅) is an unusual bird that stands upright on short legs and walks with an amusing,clumsy waddle.Penguins live in the southern half of the world.Several kinds live on the frozen ice of the Antarctic.Others are located farther north in areas touched by cold ocean currents that originate in Antarctica.Penguins are popular attractions on zoos but are difficult to keep in captivity because they catch diseases easily.
Penguins lost the ability to fly 9 years ago 10 their wings developed into flippers(鳍)which serve as paddles(桨) in the water.These flippers,along with webbed (退化的) feet,make penguins fantastic swimmers and divers.Their short,dense feathers form a waterproof coat,and thick layers of fat keep them from cold weather.
Penguins eat fish,and spend much of their lives in Antarctic waters,but lay eggs and raise their young on land.While on land they make their nests in enormous colonies called rookeries.A single rookery may contain as many as a million penguins.Most species make their nests on bare ground,and lay their eggs in shallow hollows scraped in the icy dirt.Some of the species lay eggs in tunnels dug in the ground.

企鹅是一种非同寻常的鸟类.通过两个短腿站立,蹒跚步行的方式有趣而笨拙.企鹅居住在南半球.部分种类居住在南极洲冰层上.其他则生活在南极洲的远距离区域,这些区域被来自南极洲的海洋流所包围.企鹅在动物园中很受欢迎,但是由于其容易生病,圈养起来非常的困难.
企鹅在9年前失去了飞行能力,他们的翅膀退化成了鳍,在水中充当浆的功能,这些鳍,连同退化的脚,使得企鹅成为了极佳的游泳能手和跳水能手.他们短小和紧密的羽毛成为了一个防水外膜,厚厚的脂肪层使得他们能够在冷水中不感觉到寒冷.
企鹅食用鱼类,大部分时间都生活在南极洲水中,但是在陆地上产卵以及养育小企鹅.在陆地上的时候,他们在成为群栖地的大面积区域中筑巢.一个群栖地可以容纳上百万个企鹅.大部分品种的企鹅在露天地上筑巢,将卵产在浅滩凹陷处,埋入冻土层中.部门种类的企鹅将卵产在土地上挖出的道槽中.
