There is no denying the fact that keeping pets is a hotly debated topic today. Some people claim that keeping pets is a good thing to do. They believe that pets， like cats and dogs， can help relieve the loneliness suffered by senior citizens and other social members who are confined to their homes for this reason or that. They also argue that keeping pets helps mankind understand animals world and develop positive feelings toward them.
Others， however， hold the opposite view. They regard keeping pets as a useless but harmful thing to do. Firstly， pets can transmit diseases. Secondly， the noises and dung of pets are sources of pollution. Last but not least， as many rare birds and animals are kept as pets， they will surely be hunted on a large scale， which means a threat to the balance of the ecosystem.
Weighing the arguments of both sides， I am inclined to agree with the latter. Anyway， we can lessen our loneliness and express our love toward animals in other ways. And it is my beliefs that only by placing man and other species on an equal basis can us expect to have a lively and colorful world.
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.
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!
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.
the snake is a long and thin animal that lives in grass or other dark places. a snake has no legs or feet， but it can move very fast on its stomach.
snakes usually have green，yellow or black skins， which make them difficult for their enemies to find them. some kinds of snakes live in water. they can swim as freely as fish.
snakes are cold-blooded animals. in winter they hibernatein holes which are narrow enough only to hold the snakes' bodies. the snakes can sleep through a whole winter without eating and moving. they can not feel any pain. the hibernation period lasts about five months. when spring comes， the snakes come out and begin their normal life. snakes can take many things as food， such as mice， sparrows，
frogs，birds' eggs， pests and so on. people sometimes can see a snake eat a sparrow. first it moves close to the sparrow， then it puts out its tongue and brings the sparrow into its mouth and swallows it， which makes a lump in the snake's body. after some time the lump disappears.
as snakes are dreadful-looking， people are afraid of them. many people drive them away whenever they see snakes. but in chinese fairy tales， snakes are by no means bad. they seem to have human feelings.
they can change into pretty girls. people like and respect them. the most well-known is the story about the white snake and the blue snake. in fact， snakes are not as dreadful as they look. they can help us to kill mice and pests. they can provide us with delicious meat. their blood is a good drink. poisonous snakes are especially useful. we can make valuable drugs with them.

My eyes followed the crawling insects， made a fantastic travel.
I follow this time is a little， it is considered that the humble little ants. I found it is on the roof of my house. I stared at it， it is in a few big between the block - this is a few flower POTS， stop and take a walk from time to time， as if already to find food， and like around the tentacles ask partner to find food. Several times， all of a sudden it stopped at a corner. It is found a piece of bread.
Around it to go out with his companions tentacles， and soon the companions. Follow it to move the bread， they lift up and down， as if not enough. One ant ran out and soon it was with a lot of ants， they unite together to put the bread up to the front of a small hole. But not like bread is too big to carry into the hole so Im worried about them! But they sent men guarded the bread and the rest of the people went in the hole， then they seem to please the queen， then they called a lot of ants are coming. They were together， seem to be talking about something， then the queen to eat bread， wait to feed the queen， the rest of the ants cheerful a clean sweep of the rest of the bread.
Ants can really know the unity and cooperation， compared with the unity of the ants， we humans do not have them so much!
