Animals can be of great fun, but it’s important to know   21   to be safe when you’re with them. Both indoor animals and outdoor animals need to be   22   kindly all the time. This means different things    23   on the animal and the situation.    24    a wild animal, being kind may mean staying far away    25    the animal doesn’t feel threatened and so you stay    26    .

Stepping outside can mean a world full of great animals to see —     27   squirrels in trees to birds in flight. In some parts of the world, kids    28    see slithery snakes, black bats,   29  even cool coyotes. And don’t forget raccoons, skunks, and other critters    30   come out in some places at night.

The rule in the great outdoors is simple: Don’t    31  or go near an animal.   32   some of these animals may look cool or even cute, leave them    33  . These animals aren’t like regular pets. They’re not    34    to being around people and may bite or attack if you come near them. They also might have rabies(狂犬病).

Don’t ever try to   35   a wild animal. Bird feeders are OK, but other animals,    36   they look hungry, shouldn’t ever be fed. When it comes to these animals, it’s better for everyone if you stay   ____37    and check them out at the zoo, on the Internet, on TV nature shows, or in books.[来

If a pet looks sick or is injured, stay far away. An animal that    38   loves to be petted may get very    39   and even bite when it is feeling ill. Tell an adult so he or she can get   40   for the animal.

Architects often have to deal with difficult clients (客户), but Lee Ehmke's customers are especially hard to work for. They sleep through meetings. They never pay. They don't even use bathrooms when they have to go.

Nevertheless, Ehmke puts up with such rude behavior, and he does it happily. Why? Because he designs homes for gorillas(大猩猩), bears, lions, and other zoo animals. And he enjoys the challenge of looking at the world through their exotic (奇异的) eyes.

"The role of a zoo designer is to think as much as possible about what will make each animal comfortable, happy, and active," says Ehmke, director of the Minnesota Zoo in Apple Valley.

"It would be wrong to say you can know what an animal is thinking and feeling," he adds. "But we do our best to get as close to that as possible when we're designing homes for them."

Most zoo visitors focus on the animals, not on the habitats and barriers that fence the animals in. But details like these have received extra attention since December, when a female Siberian tiger escaped her enclosure (围栏) at the San Francisco Zoo. The 4-year-old, 350-pound cat killed one person and injured two others.

The incident raised fears among zoo goers and sent staff at zoos across the nation rushing to evaluate how safe their own exhibits are. Still, experts say, the tragic event should not scare people away from zoos.

"There have probably been 5 billion visits to zoos in the last 50 years," Ehmke says. "This is the first time this has happened."
