Now scientists have discovered that the dogs behave like their masters, too. Just like children, they use a “ look and learn” ways when they go about their tasks.
Scientists at Oxford universities designed an experiment to test if the dogs have the ability to copy humans’ actions by using a simple wooden box. 10 owners showed their dogs how to open the wooden box .Sometimes they use their heads to push it and sometimes they use their hands.
10 dogs were divided into two groups---Group1 and Group2. In the first part of the test, Group1 were rewarded with a piece of meat for copying their owner’s actions. Group2 were rewarded with food for not copying and using other ways. With each dog the experiment was repeated hundreds of times. Scientists recorded the time to see which group was first to get 85% right. They found that Group1finished the task much sooner than Group2.
In the second part of the test, all the dogs were only rewarded for copying the way that their owners used. Group1 reached the 85% mark more quickly than Group2.
So the scientists draw a conclusion: “Like humans, dogs can copy actions that they see. Dogs’ imitative（仿效的）behavior is shaped more by their interactions（互动）with humans than by evolution(进化).”
Scientists said，“A dog’s behavior is influenced much like that of a child; they look and learn similar behavior. We hope that owners understand the importance of their actions and use this knowledge to set good examples and therefore have a good effect on the behavior of their pets.”
【小题1】The scientists believe dog’s imitative behavior mainly comes from______________.

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(友谊) between people and animals. Dogs and other pets can give joy to people's lives. Some people think of their pets as their children. Some people even leave all their money to their pets when they die!

Animals can help people, too. Dogs can be taught to be the“eyes”for a blind person (盲人) or“ears”for a deaf(耳聋) person. Scientists have found that pets help people live longer! They make people happier, too. Because of that, they bring animals into hospitals for“visits”.

Americans hold“Be Kind to Animals Week”in 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.

If you don't have a pet, be kind to animals around you. For example, if you see a street dog, just leave it alone, or make friends with it. If others around you do bad things to animals, try to speak up. As people, we must protect(保护) animals who can't speak for themselves.
