杜甫三别
Swimming Machines
Tunas, mackerels, and billfishes (marlins, sailfishes, and swordfish) swim continuously. Feeding, courtship, reproduction, and even "rest" are carried out while in constant motion. As a result, practically every aspect of the body form and function of the swimming "machines" is adapted to enhance their ability to swim.
Many of the adaptations of the fishes rve to reduce water resistance (drag). Interestingly enough, veral of the hydrodynamic adaptations remble features designed to improve the aerodynamics of high-speed aircraft. Though human engineers are new to the game, tunas and their relatives evolved their "high-tech" designs long ago.
不准打架 Tunas, mackerels, and billfishes have made streamlining into an art form. Their bodies are sleek and compact. The body shapes of tunas, in fact, are nearly ideal from an engineering point of view. Most species lack scales over most of the body, making it smooth and slippery. The eyes lie flush with the body and do not protrude at all. They are also covered with a slick, transparent lid that reduces drag. The fins are stiff, smooth, and narrow, qualities that also help cut drag. When not in u, the fins are tucked into special grooves or depressions so that they lie flush with the body and do not break up its smooth contours. Airplanes retract their landing gear while in flight for the same r
eason.
Tunas, mackerels, and billfishes have even more sophisticated adaptations than the to improve their hydrodynamics. The long bill of marlins, sailfishes, and swordfish probably helps them slip through the water. Many supersonic aircraft have a similar needle at
物理英文 托福tpo阅读文字版part1参考译文：游泳机器
金枪鱼，鲭鱼，和长嘴鱼(或者说成是枪鱼、旗鱼和箭鱼)的游动从不停止。它们的进食，求偶，繁殖，甚至“休息”都在不断的运动中进行。事实上，这些游泳“机器”身体结构的每个部位及其功能都有利于它们更好地游行。
为了减少在水中前行的阻力，这类鱼身上产生了很多适应性变化。非常有趣的是，人类为了降低空气阻力加快高速飞机运行速度所进行的设计和这些鱼的适应性变化非常相似。这种设计只是人类工程师的初步尝试，但金枪鱼和他们的同类们已经拥有这种“高科技”设计很久很久。
男人的担当 金枪鱼、鲭鱼和长嘴鱼的流线体型简直就是一件工艺品。他们的身体光滑而坚实。从工程师的角度
来看，金枪鱼的体型近乎完美。很多鱼类的绝大多数皮肤上是没有鱼鳞的，特别光滑。它们的眼睛和身体处于同一平面，根本不会凸显出来。身体表面还覆盖着一层光滑透明的外衣，鱼鳍部分坚硬、平稳而狭窄，这些特征都有助于降低前行中的阻力。当鱼儿们不使用鱼鳍时，会将它们折回到特殊的沟槽或者凹陷的地方，与身体保持同一平面，以维持它们平滑的外形。飞机收回起落装置，和这是同样的道理。
出租司机 给我你的手
和上述特征相比，金枪鱼、鲭鱼和长嘴鱼们拥有更加精明的手段来增加它们在水中的适应性，比如他们的大长嘴。很多超音速飞机的头部就有类似的针状设计......
