阅读理解。 Zoology (动物学) deals with the study of the animals' habitat and behavior. It has nothing to do with people, so many students are wondering why they have to learn it. Our nature includes not just the humans but plants and animals as well. Everything in our environment is connected in a complex cycle. If you have a better understanding of how animals behave, then you would value nature better. Some animals, like sharks and snakes, are often misunderstood by people. They are thought of as human killers, and this is mainly because we don't understand why they behave that way. Zoology would help you learn their natural behavior as well as their habits, so you would understand why they behave in a defensive manner when they feel threatened. Studying zoology would help people know the real facts about animals. One of the sad facts is the decreasing numbers of some species of animals. It makes people realize that there is a need for nature to be always balanced. We need animals to keep the balance in our environment and for humans to survive. Zoology helps us learn the needs that animals have and we can respond by thinking of solutions we can give to the endangered species of animals. Technological progress is needed for a country to grow in terms of its economy; however, it should not force us to destroy our rainforests and oceans. People should realize that our modern lives should include the lives of the animals. Animals should not be contained in zoos but live in their natural habitats. We will learn that every living creature on the earth has the right to own a habitat and we need to fight for them to have permanent habitats. 1.
