鲨鱼的攻击
有将近400种不同种类的鲨鱼,但人们所知的攻击人类的鲨鱼仅有约30种。
许多人都知道最危险的鲨鱼是大白鲨,可能是因为他们看过电影《大白鲨》。
然而,还有其他两种危险的鲨鱼,它们是虎鲨和公牛鲨。
和人们所猜想的相反,有证据表明鲨鱼很少攻击人类。
鲨鱼(对人类)的攻击有三种方式。
在主要的情形中,鲨鱼攻击你是因为它把你错当成了鱼,但当它发觉是人肉的味道时,就会决定放弃并游开。
在第二种情形中,鲨鱼会用鼻子推搡你,以弄清你是否适合被食用,如果它觉得适合,便会咬你。
在第三种攻击中,鲨鱼只等你游过它身边,随即猛地发起攻击。
后两种攻击方式经常导致人类的死亡。
为了减少被攻击的危险,你应谨遵以下建议:
·不在黑暗处游泳。
(在黑暗处)鲨鱼可以看见你,而你无法看见它们。
·如果你有新伤口,就不要在海里游泳。
即使隔着很远的距离,鲨鱼仍能嗅到血腥味。
·不要穿鲜亮的服装或佩戴珠宝,因为色彩和发光的物体对鲨鱼很有吸引力。
·和大家待在一起,因为鲨鱼通常会避开人群。
最近,随着水上运动越来越受人们青睐,鲨鱼攻击(人类的事件)也在持续增长。
如果遭到鲨鱼攻击,请尝试以下一些建议进行自救:
·保持镇静不要惊慌失措。
·用拳头击打鲨鱼的鼻子。
·用手指戳鲨鱼的眼睛。
不要惧怕鲨鱼:
你被闪电击中的几率要比遭受鲨鱼攻击的几率大30倍。
鸽子的奇妙世界
万籁俱寂的夜晚,除了警卫员在监守敌军外,所有士兵都已睡去,突然传过枪声和火光,他们被偷袭了!
数百敌军向他们冲来。
除非他们得到援助,否则他们将面临死亡。
他们应该怎么办?
一个军官在一张纸片上迅速写下简短的信息:
“被偷袭!
赶快支援!
”
他把纸片卷起来,放进一个小盒子里,然后伸手探入一个笼子里,捉出一只鸟来。
把信息系到它的腿上,然后把鸟放飞。
它立刻飞向高空消失在黑暗中。
那只鸟能否及时到达?
他们会得救吗?
虽然这似乎令人难以置信,但那名军官所用的鸟儿和我们常在公园里看到的一种鸟是同样的——鸽子。
鸽子有奇妙的方向感,并且能在长距离之外找到回家的路。
确实,鸽子以能从1800千米之外飞回家而著名。
那就是鸽子从古代就被用来传递信息甚至邮件的原因。
然而,正是在战争期间他们发现了它们的最大用途。
在一战和二战中,鸽子被军队用来在前线之间传递信息。
因此,拯救了许多士兵的生命,甚至帮助一些重要战争取得了胜利。
鸽子是如何找到它们的方向的?
鸽子体内似乎有一只罗盘,告诉它们何处是北方。
这个罗盘究竟是如何工作的仍然是个谜。
当然,仅仅靠这个罗盘并不能让它们找到方向,它们似乎也利用它们的视觉和嗅觉来辨别它们应该怎么飞。
和人类不同的是,它们从不迷路,它们总是能找到回家的路。
