Unit 6 Man and Animals新编大学英语第二版第三册教案

Animals Should be Trained

There are a wide variety of animals in the world. And many of them are highly intelligent. So if we train some animals to work for human beings, we can save a lot of money and manpower.

First, some kinds of animals can be trained based on their capacity to do certain types of jobs better than humans. For example, since dogs have a superior ability to track down odors, we can train them to find illegal things, earthquake victims, or even ancient tombs.

Second, some animals can even lend us their hands. The monkey is a good example. Monkeys can be trained to learn to open doors, fetch tools, bring books, etc. So they can help those who cannot move about freely because of some physical problems. Monkeys make the lives of these people happier and more comfortable.

Finally, in some cases, using animals not only saves money but also trouble. Using dolphins as underwater guards can be better and cheaper than any man-made tracking devices.

In a word, animals should be trained to help humans. If we train animals in the proper way, both humans and animals can get along very well. (194 words)

Give Animals Their Freedom

Humans and animals are both creatures of nature, so we are equals. We have no right to take advantage of them. However, many animals are now being trained to work for us. Monkeys are trained as servants, dogs as hunters and sniffers, and dolphins as soldiers.

Beasts should be allowed to run freely over great distances and birds, fly freely in the blue sky. When they are in nature, they are active and able to live a normal life. But when they are kept in captivity, they are bored and frustrated.

If we have the right to choose our fate, so do animals. So when we force them to serve us, they have no freedom and are like slaves. What’s more, a lot of animals lose their lives when they help humans. But most of them don’t care about their lives at all. As we know, life belongs to us only once and therefore is priceless, and it is also true with animals. But we show no mercy to animals when they have done so much for us. We are cold-blooded creatures and we should criticize ourselves.

In brief, we should treat animals in the same way we treat other people. Give animals their freedom. (205 words)
