The environment pollution is more and more seriously today. We have no clean water to drink it because of water pollution. And when trees cut down, some animals disappear. There was more and more dirty smoke in the air. People’s health has been greatly affecting by air, noise and water pollution. Many people have died of disease caused by pollution. In order to live the better life, it’s time for us to protect our world.

Firstly, we shouldn’t throw away rubbish everywhere. And we should recycle, reduce and reuse things, what saves money and reduces pollution. Use things so long as possible. Don’t use plastic bags. Besides, we must plant more trees and stop people cut them down. We hope our world will be more and more beautiful.

2 . It was a perfect summer morning on the beach in Rio De Janeiro. A man set up his umbrella and chair near the water and was ready to read his book. Just then, when he looked toward the sea, he noticed a small shape that came out of the water. It slowly made its way out onto the sand and began to flap its wings. It was obviously weak and tired.

When the animal was just a few feet away, the man couldn’t believe his eyes. A penguin(企鹅)? Penguins don’t live in Rio. The man was amazed. He looked around to see if there was anyone else noticing this strange sight.

A jogger soon appeared, followed by another. They stopped and stared. It was clear that the penguin was having trouble breathing. The first jogger looked at the sea and said, “Poor thing, so far away from home.”

The penguin fell to its side. It had swum 2000 miles, trying to find the tiny fish that penguins like to eat. Why did the penguin need to travel so far? Perhaps it was confused (使糊涂) by moving ocean currents (水流) and temperatures—common effects of global (全球的) warming. The penguin needed help. It would not survive on the hot sand.

One of the joggers phoned for help, and soon some firemen arrived. The man was glad that the penguin would soon be safe, although he felt a little sad too.

The event on the beach at Rio happened some time ago. It was only the beginning of penguin migration (迁移) to Brazil. Since that time, hundreds of penguins have appeared on the coasts of Brazil. They come all the way from Patagonia and the Straits of Magellan, southern parts of South America. They land on the sands very tired and hungry, and many of them die. Some are shipped or flown back to colder waters farther south.

Perhaps the experience of the penguins will help us better understand the serious effects of human activities on climathte change and on the condition of our planet.
