Dogs have an understanding of fair play and become angry if they feel that another dog is getting a better deal, a new study has found.
The study looked at how dogs react when a companion is rewarded for the same trick in an unequal way. Friederike Range, a researcher at the University of Vienna in Austria, and her colleagues did a series of experiments with dogs who knew how to respond to the command “give the paw “. The dogs were normally happy to repeatedly give the paw, whether they got a reward or not. But that changed if they saw that another dog was being rewarded with a piece of food, while they received nothing.
“We found that the dogs hesitated significantly longer when obeying the command to give the paw,” the researchers write. The unrewarded dogs eventually stopped cooperating.
Scientists have long known that humans pay close attention to inequity. But researchers always assumed that animals didn’t share the trait. “The argument was that this is a uniquely human phenomenon,” says Frans de Waal, a professor of psychology at Emory University in Atlanta.
That changed in 2003 when he and a colleague did a study on monkeys. The monkeys had to hand a small rock to researchers to get a piece of cucumber in return. They were happy to do this. But if they saw that another monkey was getting a more delicious reward, a grape, for doing the same job, they would throw away the food and rock, and at some point just stopped performing.
In that experiment, the monkeys considered the fairness of two different types of payment. But when Range and her colleagues did a similar study with their trained dogs, testing to see if dogs would become upset if they only got dark bread when other dogs received sausage, they found that as long as the dogs got some kind of food payment, even if it wasn’t the most delicious kind, the animals would play along.
【小題1】How did the dogs in Range’s study react to the order of “giving the paw”?
A.They took the order even without being rewarded. |
B.They took the order only when rewarded. |
C.They turned a deaf ear to repeated orders. |
D.They hesitated longer when given repeated orders. |
A.originated from Range’s research on dogs. |

C.began the argument that only humans are aware of inequity. |
D.was conducted to find out how monkeys reacted to humans’ orders. |
A.was given less work. |

C.was given the same type of food. |
D.was given more delicious food. |
A.care more about whether they are rewarded. |
B.care less about what they are rewarded with. |

閱讀表達:
[1]An 18-year-old student was struggling to pay his fees. He was an orphan, and not knowing where to turn for money, he came up with a bright idea. He and a friend decided to host a musical concert on campus to raise money for their education.
[2]They reached out to the great pianist Ignacy J. Paderewski. His manager demanded a guaranteed fee of $2000 for the piano recital. A deal was struck and the boys began to work to make the concert a success.
[3]The big day arrived. But unfortunately, they had not managed to sell enough tickets. The total collection was only $1600. Disappointed, they went to Paderewski and explained their plight(困境). They gave him the entire $1600, plus a cheque for the balance(差額) $400. They promised to pay the cheque at the soonest possible.
[4]“No,” said Paderewski. “This is not acceptable.” He tore up the cheque, returned the $1600 and told the two boys: “Here’s the $1600. Please deduct(扣除)whatever expenses you have spent on. Keep the money you need for your fees. And just give me whatever is left”. The boys were surprised, and thanked him a lot.
[5]It was a small act of kindness. But it clearly marked out Paderewski as a great human being.
[6]Why should he help two people he did not even know? We all come across situations like these in our lives. And most of us only think “If I help them, what would happen to me?” The truly great people think, “If I don’t help them, what will happen to them?” They don’t do it expecting something in return. They do it because they feel it’s the right thing to do.
[7]Paderewski later went on to become the Prime Minister of Poland. He was regarded as a great leader in Poland’s history.

Do you want to live forever? By the year 2050, you might actually get your wish — if you are willing to leave your biological body and live in silicon circuits (半導(dǎo)體電路).But long before then, perhaps as early as 2020, some measures will begin offering a semblance of immortality (虛擬的永生).
Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your personal chronicles (履歷). By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.
Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp(頭皮) and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
At first, the Soul Catcher's companion system — the Soul Reader — might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities (永生實體). Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine.
For people who choose not to live in silicon, semblance of immortality would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.
1.The main idea of this passage is that _______.
A.human beings long for living forever
B.there are many difficulties in making the Soul Catcher
C.people might live forever as technology develops
D.the invention of Soul Catcher has great importance
2.According to this passage, a Soul Catcher will be ______.
A.a(chǎn) new machine on which research measures have already been made
B.a(chǎn) new invention in order to catch and keep human's thoughts and emotions
C.made by British scientists to offer something that looks like living forever
D.made of silicon circuits which can catch people's nervous activity
3.According to the writer, semblance of immortality is ______.
A.to be a reality sooner or later B.far from certain
C.just an idea that couldn't t be realized at all D.a(chǎn) fading hope
4.The meaning of the underlined word "revitalize" in the fourth paragraph is close to .
A.make dead B.make famous C.make known D.make active
