動物英語作文 篇1

  As is often read in the newspaper reports, wild life especially the rare species is threatened with extinction. Human beings are making attempts to hunt wild animals for a big profit.

  which, of course, results in a sharp decrease in the number of animals. So it is high time for us to take quick action to protect them. First of all, it’s quite necessary for every citizen to realize the importance of animal protection. Only by knowing its importance can people develop a sense of .

動物英語作文 篇2

  Animals were friends or foes of humanity at different stages of the human history. In modern times, experiments upon animals have been a breeding ground for spirited debate. Some animal rights activists argue that we should ban animal experiments altogether because subjecting animals to experimentation is unwarranted on moral grounds, whereas some other people contend that the advancement of science necessitates animal testing. Personally, I am in favor of the latter view.

  Granted, mounting empirical evidence suggests that many animal experiments are performed callously without any heed to the discomfort or pain that laboratory mammals endure. For one thing, improper confinement of test animals such as locking them up in cramped cages is inhumane; and this, in turn, can severely disrupt natural biological functions of the test animal. For another, the effects of vaccination or vivisection conducted on live mammals can be chilling. In extreme cases, they constitute sheer torture of animals.

  Nevertheless, from a more pragmatic standpoint, evidence abounds that animal subjects are still an indispensable part of scientific research at this phase of human development. In the first place, drug experimentation on live mammals is, indisputably, far more effectual than experimentation on bacteria or on other lower species in determining drug safety. Medical history informs that drugs that can potentially exert grave side effects on homo sapiens must be tested by pharmaceutical companies on live mammals first to ascertain their toxicity. In the second place, in the realm of space research, live animals are still practical alternatives on a flight not considered to be sufficiently safe for human astronauts. And I would be hard-pressed to imagine the scenario that human lives should be put at stake when the objective of a space mission is merely to identify living creatures reaction to outer space experience. Lastly, lab research about the behavioral tendencies of chimpanzees, gorillas or other members of the primate group is also a worthy endeavor, in light of the fact that it generates outcomes consistently advancing anthropological and genetic sciences.

動物英語作文 篇4

  Zoos are often controversial because many people believe they are necessary or even harmful .If properly managed, I feel that zoos have a lot of value. In fact, I believe zoos are useful in two main ways: educating the general public and advancing scientific research.

  Zoos can be wonderfully educational places. They provide a safe, controlled environment to learn about a specific species. Children can feel safe exploring the world of the chimpanzee there, and adults can learn about and see types of birds they’ve never seen before . Unlike in the wild , there’s no worry of being physically harmed by an animal.

  Zoos are also important for the research opportunities they provide. Research is safer and easier to conduct than in the wild. Scientists can feel secure in the confined area of the Zoo. For example, while conducting a medical experiment in an open field ,scientists have to worry about both the animal they have to worked with, and also other animals nearby .In zoos, however ,they need only worry about the research subject.

  In the wilderness, animals are also much harder to track and monitor. Zoos make research less time-consuming and expensive. Long term follows-ups are easier too, since even with monitors, wild animals often are killed and disappear. In zoos, researchers can observe an animal’s entire life span.

  Overall , I feel that properly managed zoos provide excellent opportunities for education and research, and are therefore very useful .

  Wild yak is also named wild ox, and the Tibetan pronunciation is Yagui, which is of the same species with domesticated yak. As a typical alpine animal which can endure extreme cold, it is a first class national protected animal unique to the Qinghai-Tibet Plateau. Located in Qinghai, Tibet, southern Xinjiang, northwestern Gansu, western Sichuan and other places. It inhabits the alpine meadow strips at an altitude of 3000-6000 meters, inaccessible mountains and large peaks, mountain basins, alpine grasslands, alpine deserts, etc.
