Animal
is so
Lovely,
But……
Wild animals have no place in the 21st c.
Human is the creature which is the closest to God. It means we have more duties and rights for this world. Biological diversity have been damaged by the developing of modern society, which have threatened to the life of animals as well as the life of human. The extinction of animal is an alarm to human beings.
With the process of human civilization, our life become more and more comfortable and convenience, it may be a good news to man but a bad news to animals. Exhaust gases are emitted to the atmosphere, which react with each other and combine with water vapor ,and finally lead to form acid rain. Acid rain fall into lake and kill the frogs and the fishes. Time will tell you, although the recent acid rain may not directly harm to us, we would not escape from the doom if we ignore the alarm from animals. We are a part of the food chain.
Dogs exist in a wide range of sizes, colors, and temperaments. Some, such as the Doberman pinscher and the German shepherd, serve as alert and aggressive watchdogs. Others, such as the beagle and the cocker spaniel, are playful family pets, even though they were bred for hunting. Still others, such as the collie and the Welsh corgi, can herd farm or range animals. Each of the dogs just mentioned is a purebred. A mongrel dog, however--one with many breeds in its background--can just as easily fit into family life. Dogs have been with humans since prehistoric times. Over the years they have performed various services. They have pulled sleds over snowy tracts. They have delivered messages, herded sheep and cattle, and even rescued persons trapped in the snow. Dogs have served as a source of food, too. The ancient Romans are said to have prized certain kinds of dog stew. The Aztecs of ancient Mexico raised tiny dogs, thought to be the forebears of the chihuahua, to feed the large carnivores in the private zoos of the Aztec rulers. In the past dogs have even been worshiped as gods. Recently, they have been used in drug research, medical experimentation, and space science. Soviet scientists launched dogs into space to test the ability of mammals to survive the rigors of space travel before people were sent up. Dogs are trained as guard dogs in peacetime by the United States Army and other military services. Because of their keen sense of smell, dogs are used by police at times to track down escaped prisoners. Law enforcement agencies also rely on the dog's acute sense of smell to uncover illegal drugs. And specially trained dogs serve as the "eyes" of the blind, guiding the steps of their sightless masters around obstacles and hazards.
Dolphins are very clever. People often train them so that they can give a dolphin show which brings people a lot of happiness and joy.
Unluckily, the number of dolphins is getting smaller and smaller. Because of water pollution, there is less and less space for dolphins. Many people make money by hunting dolphins. If we don’t protect them, maybe we’ll lose our good friends one day. As a student, I hope more and more people should take actions to protect dolphins.
Dolphins are very friendly and peaceful. They never attack people. Instead, they have saved many people in danger in the past years. How helpful the dolphins are!
Otherwise, it will bite in its own defense. The wild ancestors of all dogs were hunters. Wolves and other wild relatives of the dog still hunt in packs for their food. Dogs have retained the urge to be with the pack. This is why they do not like to be left alone for long. Some breeds of dogs still retain the hunting instinct.
Most of the human’s diets come from animals, which means the dangers that are threatened not only the animals but also the human.
Several serious diseases from animals have brought us into the hell in the beginning of the new century. For example SARS, the horrible disease has killed thousands of people which was attributed to eating the ill wild animals.
Dogs are not always well thought of, however. In recent years dogs in the city have been in the center of controversy. Some people have criticized dog owners for allowing their pets to soil sidewalks and lawns, although in some cities laws oblige owners to walk their dogs along street curbs. In turn, dog owners have argued that the animals serve as protection agaiΒιβλιοθήκη Baidust vandals and burglars and thus protect their detractors as well as their owners. When a person decides to own a dog, he should be prepared to care for it properly. For a dog to stay healthy it must be correctly fed and adequately groomed, and its medical needs must be met. For a dog to be well-mannered it must be properly trained. It should never be ill-treated or mishandled.
As the end of the food chain, we should spend money on preventing wild animals which is a confession from the evil consequence. I believe no one would neglect the alarm from animals if he recognized it, no one would be of parsimony with the money if it is used in preventing himself. Development of society and preventing animals are our right and duty which also need us to balance

Dolphin is my favourite animal.
It is one of the most precious animals. Their bodies are very long, about one zhang（丈）. Dolphins live in the sea. They live on fish, shrimps and so on.

THE DOG
The dog is one of the most popular pets in the world. It ordinarily remains loyal to a considerate master, and because of this the dog has been called man's best friend. Class distinctions between people have no part in a dog's life. It can be a faithful companion to either rich or poor. Dogs have been domesticated for most of human history and have thus endeared themselves to many over the years. Stories have been told about brave dogs that served admirably in war or that risked their lives to save persons in danger. When Pompeii--the Roman community destroyed by Mount Vesuvius in AD 79--was finally excavated, searchers found evidence of a dog lying across a child, apparently trying to protect the youngster. Perhaps few of the millions of dogs in the world may be so heroic, but they are still a source of genuine delight to their owners. A dog fits easily into family life. It thrives on praise and affection. When a master tells a dog that it is good, the animal happily wags its tail. But when a master scolds a dog, it skulks away with a sheepish look and with its tail tucked between its legs. People in the city as well as those in other areas can enjoy a dog. Mediumsize or small dogs are best suited for the confines of the city. Large dogs need considerable exercise over a large area.
