動(dòng)物英語(yǔ)作文 篇1
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.

animals are natural resources that people have wasted all through our history. animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. thousands of kinds of animals have disappeared from the earth forever. hundreds more are on the danger list today. about 170 kinds in the united states alone are considered in danger.
why should people care? because we need animals, and because once they are gone, there will never be any more.animals are more than just beautiful or interesting. they are more than just a source of food. every animal has its place in the balance of nature. destroying one kind of animal can create many problems. for example, when farmers killed large numbers of hawks, the farmers` stores of corn and grain were destroyed by rats and mice. why? because hawks eat rats and mice, with no hawks to keep down their numbers, the rats and mice multiplied quickly.
luckily, some people are working to help save the animals. some groups raise money to let people know about the problem. and they try to get the governments to pass laws protecting animals in danger. quite a few countries have passed laws. these laws forbid the killing of any animal or planton the danger list. slowly, the number of some animals in danger is growing.

In the morning, my grandmother woke me up. After breakfast, my grandparents took me to the zoo. We went there by bus.

Human beings are different from animals in many ways. One of the differences is the ability of human beings to build. It is true that many animals are builders. Birds make nests, and bees make hives. But no animal could build the pyramids or the Great Wall or the Eiffel Tower. The variety, size, and beauty of the structures built by human beings is simply unsurpassed.
Another difference is the ability of human beings to use intelligence. Many animals are probably more clever than we realize, but no animal has the ability to write, to reason, or to speak. Only human beings can invent computers, make use of solar energy. Only human beings paint, draw, compose music, and write poetry.
These are but a few of the differences between human beings and animals. It is our special abilities that give us power to affect the world for the benefit of all mankind. We should be thankful for those abilities and learn to use them in a more wise way.
