【答案解析】[听力原文]
Every week, we see animals on TV, in the movies, or in advertisements. Some of these animal actors are known and loved by many.
Most TV and movie studios get their animal actors from talent agencies. These are companies that "rent" animals to studios — everything from dogs and cats to spiders and snakes. How do the agencies find the animals? Some rear and train certain kinds of animals, like horses or chimpanzees, themselves. Usually, owners take their pets to a talent agency, and the agency helps to match the animal to a job. Today, a dog or cat owner can make from $200 to $400 per day. Of course, the talent agency gets part of that fee.
Most animals are chosen for their looks, but personality is also important. Studios often want a friendly animal that likes different people. Most important is that the animal can be trained. Animal actors have to follow instructions and sit for long periods of time without moving. Filming for a ten- second TV commercial can sometimes take hours. This can be hard for the animal, so filmmakers often use several animals that look alike for one role.
In general, many trainers say that dogs are the best to work with, and cats are the most difficult.
