Last year I worked at a sweet factory. I put sugar on sweets and biscuits. I thought it was nice, and !
was a big fan of sweets. Well, I came home with sugar in my hair, nose and ears! It was unpleasant
The smell was so strong that I could smell it for ages. I worked there only a week. And now I don't like
sweets now at all.

I worked for one summer at a safari park. I liked feeding the penguins and the other animals. But
cleaning up after them wasn't much fun for me. The worst job was in the monkey reserve. The visitors
could have a free ride with monkeys. At the exit we had to stop the monkeys from getting into the
next reserve. I didnt like to run after them and catch them as it was too hot.

My job was really hard. I took customers' orders and answered the calls. I worked at a call centre. I
didn't like my job. because people were not polite. It was difficult in the beginning. But later. I learnt
not to take it too seriously. Once. I got so angry with a customer and shouted back at him. That month
I lost my job.

№ 478 1) Докажем, что число 217 не делится на 17. Для этого разобьем число 217 на слогаемые так, чтобы ответ на вопрос об их делимости на 17 был очевиден: 217 = 170 + 47. Первое слагаемое делится на 17, а второе нет. Значит, и их сумма не делится на 17.
