Question

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______________.

A．proper rewards	B．domestication
C．human-dog interactions	D．evolution

小题2:The best title may be “___________________”

A．Dogs can finish their tasks quickly.	B．Dogs are interesting animals.
C．Masters always set good examples.	D．Dogs behave like their masters.

小题3:From the experiment, we know __________________.

A．It took the two groups of dogs the same time to finish the required task.

B．The dogs that copied their masters finished the required task much sooner.

C．The dogs that were encouraged to copy their masters finished the task more slowly..

D．The dogs that were encouraged not to copy their masters finished the task more quickly..

小题4:According to the last paragraph, we can infer ______________.

A．a cruel man can raise a cruel dog

B．dogs can be influenced by anyone

C．dogs always behave positively

D．dogs are the best kind of pets

Answer 1

小题1:C
小题2:D
小题3:B
小题4:A

试题分析：短文大意：这篇短文主要讲述了狗的模仿行为，并且通过两个实验证明了这一现象。从而告诉养狗的人，自己的行为也会影响自己的狗的行为。
小题1:细节理解题。根据Dogs’ imitative（仿效的）behavior is shaped more by their interactions（互动）with humans than by evolution(进化).”描述，可知科学家相信狗的模仿行为主要是来自人—狗之间的互动。故选C。
小题2:标题归纳题。阅读短文可知这篇短文主要介绍了狗的模仿行为。故选D，狗的行为举止像它的主人。
小题3:细节理解题。根据短文第二三段描述，可知第一组狗得到的奖赏诱惑力要大。在第一次实验当中模仿主人行为的组完成任务较快，在第二次都模仿主人行为的试验中，还是第一组完成任务较快。故选B。
小题4:推理判断题。这篇短文主要讲述的就是狗的模仿行为，因此如果主人行为粗暴，他的狗也会如此。故选A，恶人养恶狗。
