Question

【题目】

Science is proving what pet owners have long believed: Dogs understand what we're feeling. Especially, dogs can recognize(识别) the difference between a happy

and an angry human face, a study published Thursday in Current Biology suggests.

It's the first research to show that dogs are sensitive (敏感) to our facial expressions, says the author Ludwig Huber at the University of Veterinary Medicine, Vienna.

In the Austrian study, 20 different kinds of pet dogs were taught to play a computer game through a series of exercises. In the first step, the dogs were shown two touch screens, one with a circle and one with a square. Through the exercises, they learned that a treat would appear if they chose the right one.

Eleven of the 20 dogs were able to catch on to rules of the game and make it to the next test, where they were shown photos of happy and angry faces. The dogs were rewarded if they picked certain expression correctly. During the test, the dogs were shown only the upper half or the lower half of a face.

It was easier to teach the dogs to choose a happy expression than an angry one, suggesting the dogs do indeed understand the meaning behind the expression, Huber

says.

As a test, the dogs were then presented with:the same half of the faces they saw during the training, but from different people，

the other half of the faces used in training，

the other half of new faces，

the left half of the faces used in training.

In the cases, the dogs chose the right answer 70 to 100 percent of the time.

Dogs who had been trained to recognize an expression of anger or happiness on the upper part of a face could find the same expression when shown only the lower part. Huber says, "The only possible explanation is that they recall from memory of everyday life how a whole human face looks when happy or angry."

Dog owners know their pets not only recognize emotions but also understand the feelings.

【1】B

推理判断题。根据Science is proving what pet owners have long believed: Dogs understand what we're feeling.“科学证明了宠物主人长期以来的信念：狗能理解我们的感受”，故推断这篇文章是介绍科学方面的内容，故选B。

【2】A

细节理解题。根据Eleven of the 20 dogs were able to catch on to rules of the game and make it to the next test, where they were shown photos of happy and angry faces.可知在研究中，有11种狗能理解比赛规则，故选A。

【3】A

细节理解题。根据the same half of the faces they saw during the training, but from different people，可知在训练时他们看到不同人的的半边脸，故选④，根据the other half of the faces used in training，可知在训练时用脸的另一半，故选③，根据the other half of new faces，可知新面孔的另一半，故选①，根据the left half of the faces used in training.可知在训练中使用的脸的左半部分，不是右半部分，因此不选②。故选A。
