As many as 10 of the 17 kinds of penguins（企鹅）may be in danger of disappearing. The number of penguins have decreased(减少) by 30% since 1987.
　　Penguins are black and white birds that live in the southern part of the world. They are common in South America，New Zealand，Australia and South Africa. Many live near cold waters. But some live near warm waters in Galapagos Islands. Penguins cannot fly，but they are fine swimmers. Penguins eat fish and krill(磷虾).
　　The warming of the earth is the decrease in penguin populations. The heating of the air has caused ocean waters to become warmer. Higher water temperatures have reduced the supply of fish and krill. Some years later these birds are completely unable to reproduce(繁殖).　 Besides，many adult penguins die of hunger.
　　Widespread(广泛的) fishing，exploration for oil and oil leaks(漏) also make penguins be in danger. Poisonous organisms(生物) in ocean water are another danger. Penguins also have their enemies，including wild dogs，sharks，seals and sea lions.
　　News about penguins is not all bad，however. Several years ago，oil leaking from a ship hurt 40% of the penguins in South Africa. The penguins became covered with oil. But thousands of people helped clean and treat the birds well. Then they returned the penguins to the wild.　 Now these South African penguins are reproducing in higher numbers than before the oil leaking.

What does a policeman usually do? It is not an easy job to describe. After all, a policeman has a number of jobs in one. A policeman often has to control (控制) traffic, either on foot in the center of a town, or in a police car on the roads. In Britain, he might be in the Traffic Police and spend most of his time driving up and down main roads and motorways. A traffic policeman has to help keep the traffic moving and help when there is an accident.
　　A policeman has to keep peace, too. If there is a fight or some other disturbance, the police can come and restore order. And they often have to deal with situation at great risk（冒险） to their own safety.
　　We expect the police to solve crime, of course, so an ordinary policeman, even if he is not a detective (侦探), will have to help look for the criminals at times.
　　And who do we call when there is an emergency (紧急情况)---an crash, a fire, a road accident, or a robbery? We call the police. So a policeman has to be prepared to face any unpleasant emergency that may happen in the modern world.
The police do an necessary job, they do it very well and I support them, but I do not think that I could ever do the job of a policeman.
Different Roles of the Police
