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_____to sudden temperature changes. Therefore it makes an excellent habitat for a_______animal. Another advantage is the water's ability to easily support body weight.________has________the same density as water, so a fish in water is almost______. This "weightlessness" in turn means two things: One, a fish can get along with a light weight and simple bone structure, and two,_______to a fish's size are practically removed. Yet there is one basic difficulty to living in water—the fact that it's______. For a fish to move through water, it must actually_______it aside. Most can do this by_______back and forth in_____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_____itself forward. The fact that water is incompressible has______shaped the development of fish. A flat and______shape can be moved through water only with difficulty.

【参考译文】

对我们来说，鱼居住的环境总像是冷的，黑的，神秘的。但是住在水里是有很多好处的，这些好处使鱼成为他们所应该成为的东西。一个是因为水是不易受温度的突然变化而影响，它为冷血动物制造了一个很好的繁殖地。另一个好处是，水可以很容易地支撑身体的重量。原生质和水有近似相同的密度，所以鱼在水里会失重。反过来，这种失重意味着两件事情，一是，一条鱼有很轻的体重和简单的骨骼结构，二是，对于鱼尺寸大小的限制实际上已经消失了。但是住在水里一个最基本的难题还没有解决---不能压缩的事实。对于一条在水中穿梭的鱼来说，它必须用它的鳍来推动水。大多数可以通过蛇形摆动来实现。鱼通过向前移动它的头，随着它的身体和尾部灵活的曲线摆动来实现推动水来运动。接下来，水顺着鱼回流的方向靠近鱼的尾巴，然后帮助推动鱼前进。水是不能压缩的这个事实，逐渐地使鱼的发展成形。一个平面的和有角的形状只能在水里被困难得移动。由于这个原因，鱼有一个基本的形状可以完美的适应和处理这个特质。

祝大家每天进步一点点！
