3.The long trunk of an elephant is a wonderful example of skill.The neck of four-footed animals is usually long,to have them reach their food without difficulty,but the elephant has a short neck,to make him more easily support the weight of his huge head and heavy teeth.His long trunk lets him get his food easily.The trunk of an elephant is to him what the neck is to other animals.It is also a nose to him,for at the end of it there is a empty place like a cup,and in the bottom of the cup are two holes,and the animal smells and breathes through them.It is an arm and a hand too,so that it has been said that the elephant carries his nose in his hand,and it might also have been said that he breathes by his hand.
At the end of the trunk,there is a strange part,about five inches long,which forms a finger.With this finger the animal can pick up the smallest piece of money from the ground,and he has been taught to make marks like letters with a pen.

分析 大象的长鼻子是一个很好的技能方面的例子.四脚动物的脖子通常是长的,毫不费力的够得着食物,但是大象有着很短的脖子,让它更加容易得支撑巨大头部和重重的牙齿.他的长鼻子让它容易地得到食物.
大象鼻子是给自己的,而脖子是给其他动物的.象鼻本身也是一个鼻子,因为在它的末端有一个空空的像杯子一样的地方,在杯子的顶端有两个洞,动物通过它们来呼吸闻味.它也是一个胳膊也是一只手,因此据说大象用手拿着鼻子,也可能是通过手来呼吸.
在鼻子的末端有一个奇怪的部分,大约5英寸长,一个手指的样子.有了这个手指,动物可以从地上捡起最小的钱币,而且一直被教给用钢笔来做像字母那样的符号.
一只成年大象的象鼻大约8英尺长.大象有着如此大的力量以至于它可以用鼻子来撞倒一个人.
