一、將下列英文翻譯成中文。（20 分） 
 Although mutations do occur naturally in organisms over the course of many generations, research has shown that environmental factors—radiations and chemicals—increase the rates and types of mutations. A prime example of this is the enormous increase in animal deformations in areas surrounding the Chernobyl nuclear plant. Since the accident, 197 deformed calves and about 200 abnormal piglets have been born. The severity of these deformities is frightening, including animals with no eyes, deformed skulls, and distorted mouths.

生物突變雖然有可能會自然地發生在有機生命中藉由許多世代的傳遞，但研究已發現環境因素–輻射與化學物–能增加突變的種類和機率。最主要的例證在車諾比核能發電廠的附近，發現大量增加動物畸形的情況。自從發生意外以來，已生出197隻畸形的小牛與大約200隻畸形的小豬。這些嚴重的畸形案例是如此的驚悚，包含沒有雙眼、頭顱變形、嘴部扭曲的動物。
