分析 这篇短文主要描述了长颈鹿的一些生理特点及其生活习性.长颈鹿是陆地上最高的动物.它可以高于5.5米.脖子能够达到1.9米长.但是脖子上只有九块骨头.和人是一样的.甚至是小鸟也比长颈鹿脖子上的骨头要多.长颈鹿脖子上的每块骨头都很长.这个使得长颈鹿与众不同.雌性长颈鹿一次生产一只小长颈鹿,长颈鹿宝宝出生时1.9米高.9岁时完成成长.长颈鹿因为脖子长可以吃更多的叶子.
解答 46.B 词义猜测题.根据下文Its neck alone may be 1.9meters long它的脖子长1.9米,结合常识可知此处指的是长颈鹿,故选B.
47.C 细节理解题.根据the same number as in the humans'.Even a small bird has many more bones in its neck than a tall giraffe.可知鸟类脖子上的骨头要比人多,故选C.
