题型：单项选择题 A1/A2型题

Mary Buendia once spent a day in an airplane, looking for a cat．She didn't find it that day．The plane flew around all over the world for three weeks with the cat on board. She finally found it in the cargo hold and sent it home first-class．Another time, she found two suitcases full of birds from Turkey．But her strangest experience was when she pulled a snake out of a man's pants．

Mary Buendia is an animal health inspector at JFK Airport in New York．She takes care of all the animals that pass through the airport and checks that they are healthy．In the Animal Health Center, there are areas for dogs, cats, reptiles, birds, and fish. There is also an area for very big animals．The biggest they ever had was a black rhino．"It was no problem," she says．

At the center, they receive all types of animals—monkeys, wild cats, poisonous spiders．It's impossible for one person to know about all of these, but there are 20 people working with Mary．Between them, they understand how to take care of the animals．She recently had to feed a group of toucans, which are rare birds．"Luckily," she says, "there is a supermarket nearby which is open 24 hours．I had to go at 2 a．m．to buy bananas．"

Mary often works at night． "It's quiet between 1 a．m． and 4 a．m．," she says, "because we don't have night flights． We try to give the animals a quiet night．" Mary clearly loves her job. "You never know what the day will bring," she says, and goes off to feed the birds．
