Question

  The giraffe is the tallest land animal. It can be over 5. 5 metres tall. Its neck may be 1. 9 metres long. Yet the giraffe has only seven bones in its neck,the same number as in the human. Even a small bird has many more bones in its neck than in a tall giraffe. Each bone in a giraffe's neck is very long,while the bones in a human neck are small. That makes the difference. A female giraffe gives birth to one baby at a time. The baby,called a calf,is about 1. 9 metres tall at birth. By the age of eight,it is fullgrown. The giraffe eats mostly (主要地) leaves.

Answer 1

內(nèi)容簡介：長頸鹿是現(xiàn)在陸地上最高的動物，它的高度可達到5. 5米，頸長1. 9米，可如此長的脖子卻和人類一樣僅僅有7塊骨頭。

1. C由第四、五兩句可知長頸鹿的頸骨數(shù)量和人類頸骨數(shù)量相同，但鳥的頸骨數(shù)量比長頸鹿的頸骨數(shù)量多，所以正確答案為(：。

2. C由倒數(shù)第三句"By the age of eight it is fullgrown."可知C項正確。

3. D由文章倒數(shù)第四句"The baby,called a calf,is about 1. 9 metres tall at birth."可知選D.
