     My name is Sarah. I like animals very much. When I left school at eighteen, I got a job at a zoo as a

student keeper. Now,five years later, things have changed-I have passed my exams and I am a full animal

keeper.   

     The money is not good. I only get£9,000 a year. You have to be outside in rain and snow, which is

hard work, and you get very dirty. But this doesn't matter to me because animals are the most important

thing in my life!   There are a hundred monkeys and fifty deer in my part of the zoo and I give them

their food and clean their houses. I also need to watch them carefully to be sure that they are all well. In

fact rhinos (犀牛) are my favourite animals and so last year I went to Africa (非洲) with a workmate for

a month to study them.   

     The zoo is open every day and I work five different days each week. I live in a small flat (公寓) twenty

minutes away and I get up at ten to seven and start work at eight. The first thing I do when I get home at

quarter past five is to take a shower!
