Wild animals like lions, squirrels, hippos and many others live in their natural habitats, in the wild. Domestic animals live alongside humans for generations — for example, cats, horses, roosters. Many domestic animals are useful to humans, for instance, dogs protect people and houses, and can hunt with humans. Domesticated animals are often called pets.

There are several groups of animals. Reptiles are air-breathing animals covered in special skin made up of scales (crocodiles, lizards, snakes and others). Birds are covered in feathers and typically are able to fly (however, penguins and ostriches can't fly). Insects are tiny animals with wings and twelve legs. Mammals (like bears, cats and seals) are warm-blooded animals that give birth to live young and feed them on milk. Humans are mammals too.

Dogs are mammals as well. Their fur can be of different length or colour (that depends on the breed). Dogs can see and smell far better than humans, but they are colour-blind. Usually pet dogs are friendly, loyal and protective of their owners. They are good companions. The average lifespan depends on the breed (small dogs often live longer than big ones).

I've got a dog, his name is Rex and he's 8 years old. He's a German shepherd and an ex-military dog. We adopted him a year ago. He likes to run and play with me and other dogs in the park. He's very smart and calm. He never bites anyone, but he can growl if a stranger gets too close to him. Everyone in the family loves Rex and he loves us in his own way.

Write one word into each phrase form the text:

1. several
of animals

2. give birth to live young and
them on milk

3. average
depends on the breed
