听力原文：W: Mr. Bacon, what is your job exactly？

B: I'm a vet, looking after sheep, horses, dogs, cats. We even have lions and tigers at the zoo.

W: What sort of pets do people bring to your clinic？

B: Mostly dogs and cats but then we have snakes and parrots and all other animals people keep as pets.

W: Snakes？ Why do you think people keep snakes？

B: I quite like snakes, but I wouldn't want one as a pet. Um...some people are very keen on them.

W: Maybe they keep snakes to frighten others. All right, do you think people spend more money on their animals than their children？

B: It depends on the people. Some are very good with their animals, some treat them far better than they would their kids, and unfortunately some are cruel with the animals.

W: What experience have you had of people who treat their animals too well？

B: Lots of animals come here with lipstick marks on the head. We regard that as a specific sort of condition here.

W: Are animals good for people's health？

B: Well, they seem to help old people. These people see one person every two days, but their animal is with them all day, and it's a companion.

W: Above all, why are you interested in your job？

B: Maybe the animals sometimes attack me and there is much paper work. The thing I like best is to deliver new animals. It always amazes me one moment you have one mother and the next moment you can have a pile of animals.
