【答案解析】[听力原文]
One of the main complaints of the city residents in the United States is the number of homeless cats and dogs. It has been estimated by Friends of Animals Incorporation that more than 30 million cats and dogs are wandering through the streets of the cities. Each year, about a fifth of these animals are destroyed. A survey of 41 cities reports that as much as 15 million dollars is spent in capturing and killing those animals every year. However, Chicago spends ＄1000000 a year in controlling its animal population. On the other hand, though you can find quite a lot of cats and dogs wandering in New York, the city government doesn"t spend any money on animal control.

A、 A survey done by Friends of Animals Incorporation.
