阅读下列短文,从下面每题的A、B、C、D四个选项中选出最佳答案。Many of us get to see wild animals only when we visit zoos. These special places let us observe amazing creatures, from big lions and tigers to tiny lizards, and learn about them. It's both fun and educational, but do animals really like living in zoos?
In the past, people could only see dead animals shown in museums. Later, explorers caught live animals and showed them off in wildlife park. Back then, animal welfare(福利) wasn't important. But today's zoos have changed a lot. They' ve made bigger enclosures(围地), taken away bars, and tried to copy animals' natural homes.
Some people think keeping animals in cages for our entertainment is cruel. But zoos say they help wildlife by teaching us about conservation. In the UK, zoos must educate the public because of the Zoo Licensing Act passed in 1981. Good zoos also support protecting programs, which help protect wildlife in their natural homes.
Zoos today state they protect endangered animals because of climate change. Robert Young, an expert at Salford University, says many species would be gone without zoos. Some zoos have breeding(繁殖) programs to save animals from disappearance. For example, Chester Zoo in the UK brought back a rare fish by breeding and releasing them into their local river.
Even though people still argue about zoos, new ways to see wildlife are being developed, like virtual reality(虚拟现实). Imagine walking through a herd of elephants in the Serengeti— it might happen sooner than you think. As technology develops, new ways to connect with nature may become more popular.
