Most people like animals because they have a wide range of practical values and add a lot of fun to our lives. We can find many different kinds of animals on the earth. Some animals, such as leopards, wolves, pandas and foxes, live in big forests. They are called "wild animals". Most of them are in danger. Most of them can pose a threat to human beings. We can only see them in the zoo. Some animals can live with humans, such as cows and dogs. They are called "livestock". Animals are very important to human beings. People catch "wild animals" to make fur products and eat them. Fox skin and crocodile skin can be used to make clothes and shoes. Now, in order to strengthen the protection of' wild animals', human beings have formulated relevant laws prohibiting the hunting of wild animals. Livestock can not only provide us with food, but also help us engage in agricultural production. Without them, our life will lack a lot of fun and increase many difficulties in production. Human meat comes from sheep and pigs, cows can provide milk for human beings, horses can become human means of transportation, and animals can help people cultivate in agricultural production. Without the help of animals, it will be difficult for human beings to survive. Let's love animals together! They are our best friends! ! !

Birds live in the Woods, squirrels live in the Woods, but you know what! Some frogs live in the Woods, too. Tree frogs are hard to find because they can change color with different environments. On the green leaves, they are the same color as the leaves. On the brown trunk, they turn brown. Some tree frogs can change from green to gold or blue because of the change of environment. Tree frogs have legs, flat toes and sticky paw pads at the ends of the toes. These sticky paw pads can prevent tree frogs from falling from trees. Tree frogs have different colors and stripes on their skin surface. Their eyes are also different in color. Some tree frogs have green eyes, some are gray, some frogs have golden eyes, and others are bright red. Their songs are different in spring and summer. One kind of tree frog makes a sound like a dog barking, and the other makes a sound like snoring. Even the chirping of some tree frogs sounds like whistling! !
