阅读下面这首宋诗，完成下列小题。

秋夜二首(其一)

孔文仲①

孤枕夜何永，破窗秋已寒。

雨声冲梦断，霜气袭衣单。

利剑摧锋锷，苍鹯缩羽翰②。

平生冲斗气，变作泪汍澜③。

【注】①孔文仲生性狷直，为官廉洁，但他反对王安石变法，因而被罢官。此诗写于被罢官后。②苍鹯(zhàn)：一种猛禽。羽翰：翅膀。③汍澜：流泪的样子。

    The giraffe is the tallest modern land animal. It can be over 5. 5 meters tall. Its neck alone may be 1. 9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the humans'. Even a small bird has many more bones in its neck than a tall giraffe. Each bone in a giraffe's neck is very long, while the bones in a human's neck are short. That makes the difference. A female giraffe gives birth to one baby at a time. The baby, called a calf, is about 1. 9 meters 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 high leaves on the trees.
