　　In America, when people say “man's best friend”, they don't mean another person. Instead they are talking about a lovely animal--a dog! These words show the friendship between people and animals. Dogs and other pets can give happiness to people's life. Some people think of their pets as their children. A few even leave all their money to their pets when they die!

　　Animals can help people, too. Dogs can be taught to become the “eyes” for a blind person or “ears” for a deaf person. Scientists have found the pets help people live longer! They make people happier, too, because the animals are brought into hospitals for “visits”.

　　Americans hold “Be Kind to Animals Week” during the first week of May. Pet shows are held during the week. Even if you don't live in America, you, too, can do this. How? First, think about how animals make your life richer. If you have a pet, take more time this week to play with it. Remember to give it delicious food. Also, be sure to keep your pet from those unwanted babies.
