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.
