V. Прочитай текст и отметь верные утверждения (T) и неверные (F)
Animal’s job.
People in Great Britain are fond of animals. There are even special hospitals, which help wild
animals. There are a lot of television films about wildlife. They are very popular with children
and grown-ups. A lot of British families have 'bird tables' in their gardens. Birds can eat from
them during the winter months. The 'bird table' should be high because cats can eat birds. The
British often think their animals are like people. For example in Britain animals can have jobs
like people. British Rail has cats and pays them for their work. Their job is to catch mice. There
is usually one cat per station. They get food and free medical help. The cats don't catch a lot of
mice but they are very popular with the British Rail staff and travellers.
