题目内容
5．As many as 10of the 17kinds of penguins（企鹅）may be in danger of disappearing．The number of penguins have decreased（减少） by 30% since 1987．Penguins are black and white birds that live in the southern part of the world．They are common in South America，New Zealand，Australia and South Africa．Many live near cold waters．But some live near warm waters in Galapagos Islands．
Penguins cannot fly，but they are fine swimmers．Penguins eat fish and krill（磷虾）．The warming of the earth is the decrease in penguin populations．The heating of the air has caused ocean waters to become warmer．Higher water temperatures have reduced the supply of fish and krill．Some years later these birds are completely unable to reproduce（繁殖）．Besides，many adult penguins die of hunger．Widespread（广泛的） fishing，exploration（探测） for oil and oil leaks（漏） also make penguins be in danger．Poisonous organisms（生物）in ocean water are another danger．Penguins also have their enemies，including wild dogs，sharks，seals and sea lions．
News about penguins is not all bad，however．Several years ago，oil leaking from a ship hurt 40% of the penguins in South Africa．The penguins became covered with oil．But thousands of people helped clean and treat the birds well．Then they returned the penguins to the wild．Now these South African penguins are reproducing in higher numbers than before the oil leaking．

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了现在有很多的企鹅处于绝迹的危险中，自从1987年企鹅的数量已经减少了30%．
解答 8．B．细节理解题．根据第二段Many live near cold waters．But some live near warm waters in Galapagos Islands．Penguins cannot fly，but they are fine swimmers．Penguins eat fish and krill（磷虾）．许多企鹅生活在冷水附近，但是也有一些生活在加巴格拉群岛的温暖的水域，它们不能飞，但是游泳非常好，它们吃鱼和磷虾．故选B．
9．C．细节理解题．根据文章最后一段thousands of people helped clean and treat the birds well．Then they returned the penguins to the wild．Now these South African penguins are reproducing in higher numbers than before the oil leaking．成千上万的人们帮助清理和非常好地治疗企鹅，然后把它们送回大自然．现在南美企鹅的数量比起石油泄漏之前已经上升到了更高的数量．故选C．
10．C．细节判断题，根据文章第三段第四段Higher water temperatures have reduced the supply of fish and krill．Some years later these birds are completely unable to reproduce．Widespread fishing，exploration for oil and oil leaks also make penguins be in danger．可知，海水的升温，人们的滥捕杀戮鱼类，石油勘测和石油泄漏是造成企鹅数量减少的原因．可知捕杀企鹅不是导致它数量减少的原因．故选C．
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．
