Animals are our friends.Please be f________ to them.
My friend, Victor, is a zoo keeper in the National Zoo. His work is very interesting but it is hard. Sometimes it is dangerous, too. Every morning the zoo keepers have to get up at five to prepare the food for the animals. Each kind of animal is given special food. For example, the lions must be given meat; the deer must be given grass and leaves; and the parrots must be given fruit and nuts. Sometimes some animals won't let the others eat their food. If this happens, each of them must be fed separately(分离地) .
Every morning each cage must be washed by the zoo keepers. This can be dangerous, especially with lions and tigers. To make the work easier, the animals are locked in the sleeping compartments (隔间) while the cages are being washed. When the animals are sick, the zoo keepers must look after them. Each sick animal is kept in a separate cage and given medicine. Sometimes they must be given injections. It is not easy to inject(打针) a sick lion!
All the keepers live near the zoo. Each of them has a small house. There he lives with his family. They do not have holidays on Sundays and public holidays. Instead, each of them has a day off during the week. Each keeper has a holiday on a different day from that of the other keepers.
The most important job of the keepers is to look after the safety of the visitors. People must be prevented from doing dangerous things. Many people have been injured because they did careless things, like putting their hands into the lion's cage.

All living things on the earth need other living things to live. Nothing lives alone. Most animals must live in a group, and even a plant grows close together with others of the same kind. Sometimes one living thing kills another, one eats and the other is eaten. Each kind of life eats another kind of life in order to live, and together they create a food chain (链条). Some food chains are simple, while others are not. But all food chains begin with the sun, and all food chains become broken up if one of the links (链接) disappears.
All life needs sunlight to live on. But only plants can use sunlight directly. Plants are ‘factories’. They make food from sunlight, water and things in the soil (土壤) and air. Plants feed all other living things. Animals can only use the sun’s energy after it has been changed into food by plants. Some animals feed directly on plants, others eat smaller animals. Meat-eating animals are only eating plants indirectly.
What about humans? We are members of many food chains. We eat rice, vegetables, and fruits and so on. We also eat meat and drink milk. But we often break up the food chains. We kill wild animals and also make rivers, lakes and seas polluted. When these rivers, lakes and seas are polluted, the fish in them can not be eaten. If we eat the fish, we will get strange illnesses.
Each form of life is linked (关联的) to all others. Breaking the links puts all life in danger.
