动物研究英语作文

Cats never fail to fascinate human beings. They can befriendly and affectionate towards humans, but they lead mysterious lives oftheir own as well. They never become submissive like dogs and horses. As aresult, humans have learned to respect feline independence. Most cats remainsuspicious of humans all their lives. One of the things that fascinates us mostabout cats is the popular belief that they have nine lives. Apparently, thereis a good deal of truth in this idea. A cat's ability to survive falls is basedon fact.Recently theNew YorkAnimalMedicalCentermade a study of 132 cats over a period of five months. All these cats had oneexperience in common: they had fallen off high buildings, yet only eight ofthem died from shock or injuries. Of course,New Yorkis the ideal place for such aninteresting study, because there is no shortage of tall buildings. There areplenty of high-rise windowsills to fall from! One cat, Sabrina, fell 32storeys, yet only suffered from a broken tooth. 'Cats behave like well-trainedparatroopers.' a doctor said. It seems that the further cats fall, the lessthey are likely to injure themselves. In a long drop, they reach speeds of 60miles an hour and more. At high speeds, falling cats have time to relax. Theystretch out their legs like flying squirrels. This increases theirair-resistance and reduces the shock of impact when they hit the ground. 猫总能引起人们的极大兴趣。它们可以对人友好，充满柔情。但是，它们又有自己神秘的生活方式。它们从不像狗和马一样变得那么顺从。结果是人们已经学会尊重猫的独立性。在它们的一生中，大多数猫都对人存有戒心。最使我们感兴趣的一件事情就是一种通俗的信念——猫有九条命。显然，这种说法里面包含着许多真实性。猫在跌落时能够大难不死是有事实作为依据的。 最近，纽约动物医疗中心对132只猫进行了为期5个月的综合研究。所有这些猫有一个共同的经历：它们都曾从高层建筑上摔下来过，但只有其中的8只猫死于震荡或跌伤。当然，纽约是进行这种有趣的试验的一个理想的地方，因为那里根本不缺乏高楼大厦，有的是高层的窗槛从上往下坠落。有一只叫萨伯瑞的猫从32层楼上掉下来，但只摔断一颗牙。“猫就像训练有素的跳伞队员，” 一位医生说。看起来，猫跌落的距离越长，它们就越不会伤害自己。在一个长长的跌落过程中，它们可以达到每小时60里甚至更快的速度。在高速下落中，猫有时间放松自己。它们伸展四肢，就像飞行中的松鼠一样。这样就加大了空气阻力，并减少了它们着地时冲击力带来的震动。 新概念3有许多类似文章的，如果你需要我可以发给你，当然网上也可以查到的

Dolphin In the vast ocean live many creatures with great intellectual and physical capacities. Dolphin is one of those great creatures, whose capacities to think and move at an astounding rate puzzle those who study their behaviors, Dolphins possess something that makes them different from all the other sea creatures. It is not strength or speed but the size of their brains. Dolphin' s brain is almost the same size as that found in the human head. They live for a ling time. Dolphins' babies are born in the water. They can grow up to three and a half meters long. Dolopins use sound to help them find their way, look for their food and talk with each other. Sound is just like their eyes and mouths.海豚 大海里住着许多智力发达、身体强健的动物，海豚就是其中之一。它反应灵敏、动作迅速，让那些研究它们行为的人们深感震惊。海豚拥有一些与其它海洋生物不同的地方，它的优势不在于它的力量和速度，而在于它的大脑。海豚的大脑与人脑大小一样大。它们的寿命很长。 海豚在水里生育，它们能长到三点五米长。 海豚利用声音帮助自己认路、觅食与彼此之间交谈。声音就像它们的眼睛和嘴一样。

In order to explore the mysteries of nature, expand human vision, increase wisdom and invent, animals should sometimes be regarded as teachers.为了探索大自然的奥秘，为了扩大人类的视野，为了增长智慧，为了发明创造，有时应当把动物当作老师。For example, the invention of radar was created step by step on the basis of the study of bats. Submarines are created on the basis of studying why fish sink into the water and why they float to the surface.比如雷达的发明，就是在研究蝙蝠的基础上一步步创造出来的。潜水艇是在研究鱼为什么会沉入水中、又为什么浮到水面的基础上创造出来的。The main reason for using model animals in research is the principle of evolution, that is, all organisms have a certain degree of correlation and genetic similarity due to their common ancestors.在研究中使用模式动物的主要原因是进化原理，即所有生物由于共同的祖先而具有一定程度的关联性和遗传相似性。Therefore, the study of Human Kinship classification can provide a lot of information about human mechanisms and diseases, which is useful in medicine.因此，对人类亲缘分类的研究可以提供大量关于人体内机制和疾病的信息，这些信息在医学上是有用的。

过去一个多世纪，医学和生命科学取得了飞跃式的发展，人类不仅建立了麻醉、安全输血、器官移植、人工心脏瓣膜等医疗技术和手段，还研发出了抗生素、疫苗和各种药物，从而消灭或控制了多种疾病，所有这些成就的取得都离不开动物实验的支持。

动物实验的意义

很多介入性的实验无法在人类身上进行，而诸如小鼠、大鼠、兔、猪、猫、狗和猴等实验动物不仅在遗传组成上与人类高度同源，而且具有和人类相似的器官和系统，并以大致相同的方式完成其生理功能，同时还会患与人类疾病类似的各种疾病。

因此科学家可以通过动物实验来模拟人类的生理活动及疾病发生和发展的过程。以诺贝尔生理或医学奖为例，截止到今年，在219位获奖者中，有183位的工作与动物实验相关。

比如本公众号前面介绍过的德国科学家冯贝林基于豚鼠实验，建立了白喉毒素抗血清和抗血清疗法，并因此获得了首届诺贝尔生理或医学奖豚鼠-早期感染实验的明星动物。
