food with very little effort,no more effort than one bite.毒液不是生存竞争强加给它们，它们也能够不用毒液捕捉动物而生存，就像今天成千上万无毒蛇那样。毒液对毒蛇来说只不过是一个舒适生存优越伎俩，它使蛇不用费多大力气就能捕捉到食物，轻咬一口即可。Lesson 20 Snake poison26第26页Contents And why only snakes?Cats,for instance,would be greatly helped;no running fights with large,fierce rats or tussles with grown rabbits-just a bite and no more effort needed.In fact,it would be an assistance to all carnivores though it would be a two-edged weapon when they fought each other.为何只有蛇才有毒液呢？譬如说，假如猫有毒液，那对猫会大有帮助，它就无须再和又大又凶老鼠边跑边博斗了，也无须再和大兔子扭斗了，只要咬一口，就无须再费大力气。所以，任何食肉动物有了毒液，都能从中获益。不过，当它们相互撕打时，毒液就成了利弊参半武，能够杀死对方，也能够被对方毒液杀死。fierce adj.凶猛 tussle n.扭打Lesson 20 Snake poison27第27页Contents But,of the vertebrates,unpredictable Nature selected only snakes(and one lizard).One wonders also why Nature,with some snakes concocted poison of such extreme potency.In the conversion of saliva into poison,one might suppose that a fixed process took place.然而，在脊椎动物中，大自然神秘模测地只选择了蛇（还有一个蜥蜴），人们弄不清楚大自然为何在一些蛇身上调制出如此高效毒液来。人们可能认为，唾液转变成毒液，其中有固定程序。concoct v.调制 conversion n.转变potency n.效力Lesson 20 Snake poison28第28页Contents It did not;some snakes manufacture a poison different in every respect from that of others,as different as arsenic is from strychnine,and having different effects.One poison acts on the nerves,the other on the blood.其实没有。有些蛇产生毒液也在各方面与另外一些毒蛇产生毒液不一样，就像砒霜不一样于马钱子碱一样。不一样毒蛇产生毒液产生效果不一样.一个毒液作用于神经，另一个毒液作用于血液。arsenic n.砒霜strychninen.马钱子碱Lesson 20 Snake poison29第29页Contents The makers of the nerve poison include the mambas and the cobras and their venom is called neurotoxic.Vipers(adders)and rattlesnakes manufacture the blood poison,which is known as haemolytic.产生神经毒液蛇有一个非洲树眼镜蛇和眼镜蛇，它们毒液称为神经毒素。蝰蛇（蝮蛇）和响尾蛇产生血液毒素，称为溶血性毒液。mamba n.树眼镜蛇 viper n.蝰蛇 cobra n.眼镜蛇adder n.蝮蛇 rattlesnake n.响尾蛇 venom n.毒液 haemolytic adj.溶血性 neurotoxic adj.毒害神经Lesson 20 Snake poison30第30页Contents Both poisons are unpleasant,but by far the more unpleasant is the blood poison.It is said that the nerve poison is the more primitive of the two,that the blood poison is,so to speak,a newer product from an improved formula.Be that as it may,the nerve poison does its business with man far more quickly than the blood poison.这两种毒液都很可怕，但溶血性毒液尤其厉害。听说，神经毒液在两种毒液中是较为原始一个，而溶血性毒液，打个比喻说，是依据改良配方生产一个较新产品。不过，神经毒辣液比溶血性毒液在人身上起作用快得多。Lesson 20 Snake poison31第31页Contents This,however,means nothing.Snakes did not acquire their poison for use against man but for use against prey such as rats and mice,and the effects on these of viperine poison is almost immediate.不过，这没有什么关系，因为蛇有毒液不是用来对付人，而是对付它猎物，诸如鼠类，毒液对这些猎物会立刻起作用。viperine adj.毒蛇Lesson 20 Snake poison32第32页
