小狗:小狗的警惕性非同寻常,它有一个特别灵敏的鼻子,能闻到3里以外东西的气息,吃食物时,它总要低下头闻一闻。它还有一双耳朵,每当听到特别的声音,它的耳朵总会竖起来,认真地倾听着外面的动静!因而,人们养它来看大门,它是人类的忠实的朋友。小狗有一张宽而大的嘴巴,嘴里有一排洁白而又锋利的牙齿,它一口就可以将一只大老鼠咬死! 小狗的眼睛不很好,大约只能看一里的距离。那么,它为什么能看准东西呢?它主要靠得是它的鼻子。参考资料:无

Polar bears have an extraordinary sense of smell. They can detect a seal’s breathing hole under three feet of snow or ice from more than half mile away. Their sense of smell is their most important sense for detecting prey on land. A polar bear can smell a seal on land 20 miles away.热心网友 时间:2024-12-14 15:20
