题目内容
20.Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly,flies like a fat chicken,eats green leaves,has the stomach of a cow and has claws(爪)on its wings when young.They build their homes about 4.6m above the river,an important feature(特征)for the safety of the young.It is called the hoatzin.In appearance,the birds of both sexes look very much alike with brown on the back and cream and red on the underside.The head is small,with a large set of feathers on the top,bright red eyes,and blue skin.Its nearest relatives are the common birds,cuckoos.Its most striking feature,though,is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip.Using these four claws,together with the beak(喙),they can climb about in the bushes,looking very much like primitive birds must have done.When the young hoatzins have learned to fly,they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20to 30birds,but in April,when the rainy season begins,they collect together in smaller living units of two to seven birds for producing purposes.

分析 在亚马逊河和奥利诺科河沿岸,居住着一种鸟,这种鸟在会飞前在河里游泳;飞起来像是一只肥肥的鸡;吃绿叶;有个像牛一样的胃并且在没长大时有在翅膀上长有爪子.它们在河上4.6米高的地方筑巢,这个重要特征是为了确保幼鸟的安全.这鸟的名字是麝雉.
从外观上看,雄鸟和雌鸟长的很相像,背上都是棕色的,下面都是乳白色和红色的.头很小,在头顶上有一大块羽毛,明亮的红眼睛,蓝皮肤.跟麝雉最近血缘关系的是平常的一种鸟,叫做杜鹃.它的最明显的特征,只是在年幼时才被发现.
麝雉幼鸟的爪子一个长在翅膀的前缘,一只长在翅膀尖.用这四只爪子和喙,它们可以在灌木丛中攀爬,看起来非常像原始的鸟类做的事情.当麝雉的幼鸟学会飞翔后,它们的爪子就不存在了.
在十二月和次年的三月的干旱期内,麝雉通常以20至30为一群在森林里飞翔.但是到了四月份雨季来临的时候,为了繁衍,它们就以二到七只这样更小的单位聚集在一起..
解答 28.D 推理判断题.根据四段大意,第一段"Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly…"引出介绍麝雉,第二段"In appearance,the birds of both sexes look very much alike…"介绍了麝雉外貌特征,第三段"Baby hoatzins have a claw on the leading edge of each wing.."介绍了年幼的麝雉外貌特征变化,第四段"During the drier months between December and March hoatzins…"介绍了麝雉旱季和雨季的活动,根据四个段落大意可知,本篇文章是关于麝雉这种鸟的外貌以及生活习性,D选项符合题意.A选项只在第四段"During the drier months between December and March hoatzins…"提及,用来概括整篇文章内容,有些片面,故排除.B选项只在第二段最后一句提及"Its nearest relatives are the common birds,cuckoos.Its most striking feature,though,is only found in the young.",用来概括整篇文章内容,过于片面,故排除.C选项中primitive birds 在文中没有介绍,只是在第三段一个句子中提及"looking very much like primitive birds must have done.",用来概括整篇文章内容,也过于片面,故排除.故选D.
29.B 细节理解题.根据第三段第一句以及第三句"Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip.""When the young hoatzins have learned to fly,they lose their claws."可知,年幼的麝雉有爪子,长大会飞之后就没有了,所以幼鸟与其父母之间的不同是,幼鸟翅膀上有爪子,故选B.
30.A 推理判断题.根据第三段"Using these four claws,together with the beak(喙),they can climb about in the bushes,looking very much like primitive birds must have done."可知,幼鸟用四只爪子和喙,可以在灌木丛中攀爬,看起来非常像原始的鸟类,原始鸟类有爪子,并用爪子攀爬.故选A.
31.D 细节理解题.根据最后一段最后一句"when the rainy season begins,they collect together in smaller living units of two to seven birds for producing purposes."可知,在雨季,为了繁衍,麝雉以二到七只这样更小的单位聚集在一起,故选D.
点评 本文介绍了麝雉及其外貌特征和生活习性,其中幼鸟外貌有很大不同.题目涉及多道细节理解题,做题时结合原文和题目有针对性地找出相关语句进行仔细分析,结合选项选出正确答案.推理判断题,在抓住关键句子的基础上进行合理正确的分析,切记胡乱猜测,做到有理有据.
