1·Modern large-mouthed snakes, such as boas and anacondas, can eat large prey because their jaw joints are positioned well behind their skulls, allowing the snakes to open their mouths very wide.
现代阔口蛇，像蟒蛇和水蟒，能吃大的猎物是因为它们的颌关节恰位于头骨的后面，能使蛇的嘴张得非常宽。
2·Then they warmed up the rats, set the hearts pumping, and dangled them in front of hungry boas.
然后，他们把死鼠的身体弄热，安装上人造心脏泵，再把死鼠放在饥饿的蟒蛇面前。
3·And as long as that rat heart kept thumping, the boas kept tightening their coils and applying bursts of pressure, sometimes for more than 20 minutes.
只要老鼠的心脏还在不停跳动，蟒蛇就不断收紧身体并一阵阵地用力缠绕，有时超过20分钟。
4·For a person who has never been to this piece of land, Amazon represents shoals, swamps, bushes, Indian tribes, crocodiles, boas and unlimited adventures.
而在一个从未到达过这片土地的人心目中，“亚马逊”又代表着河滩、沼泽、丛林、印第安部落、鳄鱼、蟒蛇以及无穷尽的冒险与。
5·The grown-ups discouraged me in my painter's career when I was six years old, and I never learned to draw anything, except boas from the outside and boas from the inside.
这不是我的过错。 六岁时，大人们使我对我的画家生涯失去了勇气，除了画过开着肚皮和闭着肚皮的蟒蛇，后来再没有学过画。
