　　To us, the environment in which fish dwell often seems cold, dark, and mysterious. But there are advantages to living in water, and they have played an important role in making fish what they are. One is that water isn't subject to sudden temperature changes. Therefore it makes an excellent habitat for a cold-blooded animal. Another advantage is the water's ability to easily support body weight. Protoplasm has approximately the same density as water, so a fish in water is almost weightless. This "weightlessness" in turn means two things: One, a fish can get along with a light weight and simple bone structure, and two, limitations to a fish's size are practically removed.

　　Yet there is one basic difficulty to living in water --- the fact that it's incompressible. For a fish to move through water, it must actually shove it aside. Most can do this by wiggling back and forth in snakelike motion. The fish pushes water aside by the forward motion of its head, and with the curve of its body and its flexible tail. Next, the water flows back along the fish's narrowing sides, closing in at the tail, and helping the fish propel itself forward.

　　The fact that water is incompressible has literally shaped the development of fish. A flat and angular shape can be moved through water only with difficulty. And for this reason, fish have a basic shape that is beautifully adapted to deal with this peculiarity.

　　【听力精解】

　　在听写部分没有过多地难为大家，把生词都放过去了，主要是针对了一些容易混淆听力的词汇。那么在此我就重点提一提那些生词，可能有一些大家听过去觉得很陌生。

　　cold-blooded animal 冷血动物

　　Protoplasm 是原生质的意思

　　incompressible 意为 不能压缩的(compress是压缩的意思，听到这个词的时候就要有反应)

　　forward motion 向前移动

　　peculiarity 特性 这个有点类似character

　　【参考译文】

　　对我们来说，在鱼住的环境往往显得寒冷，黑暗，神秘。但也有生活在水中的优势，他们都起到了重要作用，在鱼，它们是什么。其一是，水是不是受到突然的温度变化。因此，它使一个冷血的动物的优良栖息地。的另一个优势是的水的的的能力，到很容易地支持的身体的重量。原生质有大致相同的密度为水，所以在水中的鱼几乎是失重。反过来这种“失重”意味着两件事情之一，一条鱼可以和睦相处，具有重量轻和简单的骨骼结构，二，限制鱼的大小几乎删除。

　　然而，有一个基本的困难生活在水中的---事实上，它不可。为移动通过水的鱼，它实际上必须推一边。较可以做蛇形运动中来回摆动。推水的鱼，除了其头部向前运动，它的身体曲线，其灵活的尾巴。下一页的的，水流回沿该鱼的收窄双方的中，关闭在在的尾巴，和帮助的鱼推动本身的向前。

　　水是不可压缩的事实，已在无形中形成了鱼的发展。通过水，只有困难的，可移动平面和棱角分明的形状。基于这个原因，鱼有一个基本的造型精美适应处理这个特点。
