“Humans have a code of ethics (行為規(guī)范) ,” says Marc Bekoff, an animal behavior expert at the University of Colorado. “If I don’t play in a certain way, you won’t play with me. Some animals have the same code”
Scientists recently discovered that animals which live in groups, such as elephants, foxes and wolves are especially likely to follow rules. If they don’t, and each does its own thing, the group might break apart. Group members would be forced to live alone. Then they’d have a harder time hunting and raising their young.
That’s probably why a traveling wolf pack stopped and waited to let its slowly moving leader catch up. Similar social ties may have caused a captive elephant to save her friend from drowning. Selfish reasons certainly motivated the male fox, who wanted to keep playing.
Sometimes, though, animals go out of their way to do what’s right, even when there’s nothing in it for them. Nobody knows why. “It might simply feel good to be kind, just as it does for humans,” says Bekoff.
If your friend wasn’t nice to you, what would you do? Maybe you would just walk away. That’s exactly what a wild red fox did when she was play-boxing with another fox. The larger fox, a male, began pushing too hard. The little female didn’t like fighting. She ran away quietly.
“He still wanted to play,” says Marc Bekoff. So the male fox ran after his playmate, bowed down, and rolled over. His body language meant, “Don’t leave. I’ll play nicely.” The female gave him another chance, and the male wrestled more gently this time.
71 How did the little female fox show her dissatisfaction with the larger male one? (no more than 5 words)
Some Animals have the same code of ethics like human.

When scientists set out to explore the roots of human laughter, some apes(類(lèi)人猿) were just tickled(胳肢)to help. That’s how researchers made a variety of apes and some human babies laugh. After analyzing the sounds, they concluded that people and great apes inherited laughter from a shared ancestor that lived more than 10 million years ago. Experts praised the work, it gives strong evidence that ape laughter and human laughter are related through evolution(進(jìn)化).
Scientists have noted that apes make characteristic sounds during play or while being tickled, especially to signal that they’re interested in playing. It’s been suggested before that human laughter grew out of primate(靈長(zhǎng)類(lèi)動(dòng)物) roots. But ape laughter doesn’t sound like human laughter. It may be slower noisy breathing. So what does that have to do with the human ha-ha? To investigate that, Marina Davila Ross and her colleagues carried out a detailed analysis of the sounds made by tickling three human babies and 21 other primates, apes included.
After measuring 11 features in the sound from each species, they tried to find out how these sounds appeared to be related to each other. The result looked like a family tree. Significantly, that tree matched the way the species themselves are related, the scientists reported online in the journal Current Biology. They also concluded that while human laughter sounds much different from ape laughter, their typical features could have come from the same ancestor.
Panksepp, who studies laughter-like responses in animals but didn’t participate in the new work, called the paper exciting. Panksepp’s own work concludes that even rats produce laughter in response to playing and tickling, with sounds that can hardly be heard by people. Robert Provine, a scientist, who wrote the book, Laughter: A Scientific Investigation, said the new paper showed some important clues, like ape sounds that hadn’t been realized before.
69. Why did the scientists analyze the laughter made by tickling human babies and apes?
A. To try to discover if they can make characteristic sounds.
B. To see if they interested in playing.
C. To find out if the laughter of apes and humans is related.
D. To find out the differences between humans and apes.
70. Based on Paragraph 3 we can know that researchers measured the features in the sound to ________.
A. find out ape sounds that hadn’t been realized before
B. find out relations among primates’ laughter
C. see what a family tree from each species looks like
D. make a report online in the journal Current Biology
71. What can be inferred from the last paragraph?
A. Panksepp spoke highly of the new research.
B. Rat laughter is likely to be related to ape laughter.
C. Robert Provine provided some new clues for the researchers.
D. Humans don’t enjoy listening to ape laughter.
72. What would be the best title for the passage?
A. Ape study explores evolution of laughter.
B. Apes like to laugh when being tickled.
C. Human laughter and ape laughter are different.
D. Laughter: A Scientific Investigation.
