【題目】

Monarch butterflies from eastern Canada make the most amazing journey in the insect world. Each year, this butterfly travels about 3 000 miles to its winter home in central Mexico(墨西哥). How can it fly so far? And why does it make this long and dangerous trip? Scientists still don't have an answer.

For many years, people in Mexico wondered where the orange and black butterflies came from every winter. Then, in 1937, a scientist started to follow and study the butterflies. For the next 20 years, he discovered that one butterfly started its journey in Canada. Four months later, it arrived in Mexico.

The length of the butterflies' trip is only one part of the mystery. Another amazing thing is that the butterflies always return to the same area in central Mexico.

How do the butterflies find their way back to the same place? This is an interesting question because only every fourth generation(代) makes the trip south. In other words, the butterfly that travels to Mexico this year is the great great grandchild of the butterfly that traveled there last year.

Each year, four generations of a Monarch butterfly family are born. Each generation of the family has a very different life. The first generation is born in the south in late April. It slowly moves north, reproduces(繁衍), and then dies. Each of these generations of butterflies lives for generations are born, reproduces, and die. Each of these generations of butterflies lives for only two or five weeks. In the autumn, the fourth generation of butterflies is born. This generation has a much longer life. It lives for about eight months. This generation of butterflies makes the amazing journey back to the winter there, and in the spring they reproduce and then die. Their offspring will be the first generation of the next circle of life.

Today, people are still studying the Monarch butterfly. But they are not clear about everything.

【題目】

Science is proving what pet owners have long believed: Dogs understand what we're feeling. Especially, dogs can recognize(識別) 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】The passage may come from .

A. a news report B. a science magazine

C. a pets guide D. a history book

【2】How many dogs in the research could understand the rules of the game?

A. 11 B. 20 C. 70 D. 100

【3】During the test, the dogs were presented with the following faces .

①the other half of some new faces

②the right half of the faces used in training

③the other half of the faces used in training

④the same half of the faces they saw but from different people

A. ①③④ B. ①②③ C. ①②④ D. ②③④

【4】Why was it easier to teach the dogs to choose a happy expression than an angry one?

A. Because dogs wanted to make a happy expression.

B. Because dogs were rewarded for picking a happy expression.

C. Because dogs saw a happy expression more often from their owners.

D. Because dogs indeed didn’t understand the meaning behind the expressions.

【5】What can we learn from the passage?

A. Dog owners know if their pets are happy.

B. Dog owners know how to train their dogs.

C. Dogs can make different facial expressions.

D. Dogs can understand their owners' feelings.
