Imagine living locked inside a closet. You can’t choose when and what to eat or how you will spend your time. You can’t even decide when the lights go on and off. Think about spending your whole life like this. This is the life of lab animals. Now consider the needs of these animals. Chimpanzees(黑猩猩),in their natural homes, are never separated from their families. They spend hours together every day. But in a lab, chimpanzees are put in cages alone. There are no families, only cold, hard cages, and loneliness that goes on for so many years that most of them lose their minds at last. Worse yet are the experiments. Animals are given diseases they would never normally get. Experimenters force-feed(给……强行喂食) chemicals to them, conduct repeated surgeries(手术),and much more, Think of what it would be like to put up with these and then be thrown back into a cage, usually without any painkillers. Often animals see other animals being killed right in front of them. Hundreds of thousands of animals are poisoned, blinded, and killed every year in product tests for shampoos, skin creams and new cancer drugs. Although more than 500 companies have stopped testing on animals, some of them still force chemicals into monkeys’ stomachs and rabbits’ eyes. Although some facilities are better than others at caring for animals—not every lab worker kills a mouse by cutting off its head with scissors—there are no happy animals inside laboratories. Will the lab life end? When will it end? 小题1:The passage mainly tells us about .
①are very cold, and in separate cages ②feel lonely locked inside a cage ③aren’t fed anything but chemicals ④are forced to undergo cruel tests ⑤are forced to eat chemicals
