阅读下面短文，按要求完成下列各题。
Zoology is everything about animals. And people who study it are called zoologists. They want to learn about the difference between different kinds of animals, where they come from, and how they live.
What do zoologists do?
There are many different kinds of zoologists. Some try to learn everything about one animal, and some learn about a group of animals, some try to understand where new kinds of animals come from and other zoologists are interested in how animals can get sick. Many zoologists study what animals do when they are with other animals.
A famous zoologist
Charles Darwin is probably the most famous zoologist. He showed that animals are all one big family and that every kind of animal changes slowly to match the place where they live. This is called “evolution（进化）”. During his life, people laughed at Darwin, saying that people and animals couldn’t come from the same family. However, many zoologists today agree that Darwin was right.
Why is it important?
Understanding animals is important because people are animals. When we study animals, we learn about ourselves.
Do you know?
•Frogs can breathe（呼吸）without their mouths! When frogs are not in water, their bodies can take air through their skin.
•Some people say sharks never get sick, but that is not true. Sharks get sick, just like any other animal.
