范文：
Polar bears mostly live on sea ice. They are good at swimming. At birth, they weigh only a few hundred grams. But when they become adults, they may weigh as much as 900 kilograms. They can live for up to 25 years. They eat some animals in the sea.
Nowadays, polar bears are in danger. There are many reasons for this. First, it’s because the Earth is becoming warmer and warmer and there is less and less ice. Polar bears are losing their homes. Second, people kill polar bears for their fur and meat, because their fur is thick enough to keep people warm in cold winter.
It is important for people to protect them. We must stop people from killing them.

Polar bears mostly live on sea ice. They are good at swimming. At birth, they weigh only a few hundred grams. But when they become adults, they may weigh as much as 900 kilograms. They can live for up to 25 years. They eat some animals in the sea.
Nowadays, polar bears are in danger. There are many reasons for this. First, it’s because the Earth is becoming warmer and warmer and there is less and less ice. Polar bears are losing their homes. Second, people kill polar bears for their fur and meat, because their fur is thick enough to keep people warm in cold winter.
It is important for people to protect them. We must stop people from killing them.
