『壹』 鲨鱼的资料（英文）
鲨鱼属于脊椎动物门软骨纲(Chondrichthyes)板鳃亚纲，海生，少数种类进入淡水，为一群游速快的中大型海洋鱼类。
Sharks are vertebrates steel door cartilage (Chondrichthyes) elasmobranchii, Marine, a few species enter fresh water, as a group of large Marine fish speed is fast.
鲨内骨骼完全由软骨组成，常钙化，但无任何真骨头组织，外骨骼不很发达或退化，身体常被皮齿(质鳞)，牙多样化，具有硬肌，但膜骨则永不存在，脑颅无缝。

鲨鱼的起源不详，但其地质学纪录可追溯到泥盆纪(4.08亿～3.6亿年前）。鲨鱼化石在中泥盆世出现，在石炭纪（3.6亿～2.86亿年前）成为占优势的脊椎动物。现代鲨鱼出现于侏罗纪早期（2.08亿～1.87亿年前），到白垩纪（1.44亿～6,640万年前）已经发展成现存的各科。
总之，除觅食和游泳机制的改进外，进化对鲨鱼的形态改变甚微。无论对化石种和现存种类来说，牙齿在鲨鱼种类鉴别方面均有很重要作用。

『叁』 用英语介绍一种鲨鱼用6句话
鲨来鱼，被一些人认为是海自洋中最凶猛的鱼类之一。但鲨鱼中体型最大的鲸鲨却以小型海洋生物为食物，和须鲸差不多。由于食物具有某种相似性，经过漫长的生物演化，它们长得和须鲸很有相似点，这个叫做“趋同进化”。于是“鲸鲨”的名字就理所当然了。
The shark, considered by some to be one of the most ferocious fishes in the sea. But the shark in the largest whale sharks with small sea creatures for food, and whales almost. Because the food has some similarities, over a long period of biological evolution, they grow and whales very similar. This is called "convergent evolution." So the "shark" the name of behoove.

『伍』 鲨鱼皮泳衣英文介绍
鲨鱼皮泳衣是人们根据其外形特征起的绰号，其实它有着更加响亮的名字：快皮， 它的核心技术在于模仿鲨鱼的皮肤。生物学家发现，鲨鱼皮肤表面粗糙的V形皱褶可以大大减少水流的摩擦力，使身体周围的水流更高效地流过，鲨鱼得以快速游 动。快皮的超伸展纤维表面便是完全仿造鲨鱼皮肤表面制成的。此外，这款泳衣还充分融合了仿生学原理：在接缝处模仿人类的肌腱，为运动员向后划水时提供动 力；在布料上模仿人类的皮肤，富有弹性。实验表明，快皮的纤维可以减少3% 水的阻力，这在1%秒就能决定胜负的游泳比赛中有着非凡意义。1999年10月，国际泳联正式允许运动员穿快皮参赛。
而关于穿什么样的泳衣游得更快，人们已探索了许多年。泳者在水中遇到的阻力，与水的密度、泳者的正面面积、摩擦系数及泳者速度的平方成正比，因此减少正面面积和摩擦系数是设计低阻力泳衣的关键。
英文：：：The shark dried shark skin swim suit is the people according to the nickname which its contour characteristic gets up, actually it has a more resounding name: The quick skin, its core technologies lies in the imitation shark's skin. The biologist discovered that the shark skin surface roughness V shape folds may rece fluent greatly the friction force, causes around body's current of water to wind through highly effective, the shark can hover fast. The quick skin's ultra extension textile fiber surface is copies the shark skin surface to make completely. In addition, this model of swim suit also fully fused the bionics principle: Imitates humanity's tendon in the connecting point, delimits when backward the water for the athlete provides the power; Imitates humanity's skin on the cotton material, high resilience. The experiment indicated that the quick skin's textile fiber may rece 3% water the resistance, this in 1% seconds can decide that the victory and defeat in the swim meet has the extraordinary significance. in October, 1999, Guojiyonglian allowed the athlete to put on the quick skin participation officially.what swim suit but does about put on to tour quickly, the people have explored for many years. The swimming the resistance which meets in the water, with water density, swimming frontal face area, friction coefficient and the swimming speed's square is proportional, therefore reces the frontal face area and the friction coefficient designs the low resistance swim suit's key.
