The Amazing Camel
Camels are large animals with long necks and humps on their backs. They are usually brown and have thick fur to keep them warm at night.
What makes camels amazing is their ability to live in deserts. They can survive without water for over a week and go without food for several days. Their humps store fat, which can be turned into energy when needed. They also have thick foot pads to walk on hot sand easily.
I think camels are really wonderful. They are like "ships of the desert" and help people carry things across deserts. I admire their strong ability to adapt to harsh environments.Unit 4 Amazing Plants and Animals Section B 练习作业

My Favorite Amazing Animal
My favorite amazing animal is the chameleon. What makes it amazing is its ability to change its color according to its surroundings. It can turn green to hide in leaves, or brown to match tree trunks, which helps it avoid enemies and catch insects easily.
Chameleons are now facing danger because their living places are being destroyed. We should protect their natural habitats and stop buying them as pets. It's important to let these amazing creatures live freely in the wild. I hope more people can learn about chameleons and join in the protection work.
