Module 5 A Lesson in a Lab 【语篇导读】 实验室的小狗小猫们的福音来了 ! 纽约一项新的法令规定 , 用于实验的猫和狗退役后须被领养。 Life has gotten a little brighter for some lab animals in New York state.A law passed recently says that all research labs must make dogs and cats used as test subjects available for adoption( 领养 ) when testing is complete. “This is a humane law that,for these animals,provides the chance for a new life,” Governor Andrew Cuomo said.“Dogs and cats are like members of the family for many New Yorkers and this action will allow more four-legged friends to be adopted into a caring home.”The law states that a licensed vet ( 兽医 ) will determine whether or not animals are suitable for adoption.Those animals that are suitable must be made available to animal shelters to be put up for adoption. New York is the fifth state to pass such a law,following Minnesota,California,Connecticut and Nevada.The New York law was backed by the Beagle Freedom Project,a group dedicated to( 致力于 )helping animals in research laboratories. Though the Beagle Freedom Project works to protect many kinds of animals,its name calls attention to the dog most commonly used in labs.Beagles are bred( 饲养 )to be test subjects,because their small size and gentle nature makes them easy to work with in lab settings. Retired research animals often need a lot of patience and special care to recover from what they ’ ve experienced,Beagle Freedom Project managing director Loma Campbell said.“They are easily scared,” she said.“Most of them have never been outside .” While the new law is good news for dogs and cats in the Empire State,it does not address other animals commonly used in lab testing,like rats and rabbits.But the law shows a move toward removing animal research altogether. 思考 1 .What ’ s the main idea of the text? 2 .What can we learn from the last sentence of the passage ? 答案 : A law passed to protect former research cats and dogs . 答案 : Animal research will probably be forbidden in the future .
