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（互動）with humans than by evolution(進化).”
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.”
小題1:The scientists believe dog’s imitative behavior mainly comes from______________.

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

小題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.

小題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..

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

A．a(chǎn) 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

小題1:C
小題2:D
小題3:B
小題4:A

試題分析：短文大意：這篇短文主要講述了狗的模仿行為，并且通過兩個實驗證明了這一現(xiàn)象。從而告訴養(yǎng)狗的人，自己的行為也會影響自己的狗的行為。
小題1:細節(jié)理解題。根據(jù)Dogs’ imitative（仿效的）behavior is shaped more by their interactions（互動）with humans than by evolution(進化).”描述，可知科學家相信狗的模仿行為主要是來自人—狗之間的互動。故選C。
小題2:標題歸納題。閱讀短文可知這篇短文主要介紹了狗的模仿行為。故選D，狗的行為舉止像它的主人。
小題3:細節(jié)理解題。根據(jù)短文第二三段描述，可知第一組狗得到的獎賞誘惑力要大。在第一次實驗當中模仿主人行為的組完成任務較快，在第二次都模仿主人行為的試驗中，還是第一組完成任務較快。故選B。
小題4:推理判斷題。這篇短文主要講述的就是狗的模仿行為，因此如果主人行為粗暴，他的狗也會如此。故選A，惡人養(yǎng)惡狗。
