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 get food ready for the animals.

Each kind of animal eats special food. For example, the lions must eat meat; the giraffes will eat grass and leaves; and the parrots must have fruit and nuts. Sometimes some animals won’t let the others eat their food. If this happens, each of them must be fed separately(分离的). Every morning the zoo keepers must clean each cage. This can be dangerous, especially(尤其) with lions and tigers. To make the work easier, the keepers always lock the animals in the sleeping compartments(隔间) while they are washing the cages. 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 the zoo workers have to inject(注射) the sick animals, even the lions.

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(公众的) holidays. 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. They must stop those people from doing dangerous things.
