                                                                  The Giraffe

      The giraffe is the tallest modem land animal. It can be over 5.5 metres tall. Its neck bone may be 1.9 metres

long. Yet the giraffe has only seven bones (骨) in its neck, the same number as in the human (人类). 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 (雌的) 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 full-grown. The giraffe

eats mostly leaves. Because it has a long neck, it can reach the leaves high up on the trees.
