Very good — you’ve already mastered half the basic vocabulary of the Campbell’s monkey, which lives in the forests of the Tai National Park in Ivory Coast. The adult males have six types of call, each with a specific meaning, but they can mix two or more calls together into a message with a different meaning.

Having spent months recording the monkeys’ calls in response to both natural and artificial stimuli (刺激物), a group led by Klaus Zuberbuhler of the University of St. Andrews in Scotland argues that the Campbell’s monkeys have a certain form of syntax(句法).

This is likely to be controversial because despite great effort to teach chimpanzees(大猩猩) language, they showed little or no ability to combine the sounds they learned into a sentence with a larger meaning. Syntax, basic to the structure of language, uniquely belongs to humans.

“Krak” is a call that warns of leopards in the neighborhood. The monkeys give it in response to real leopards and to leopard shouting broadcast by the researchers. The monkeys can vary the call by adding “-oo”: “Krak-oo” seems to be a general word for hunter, but one given in a special context – when monkeys hear but don’t see a hunter, or when they hear the alarm calls of another species.

The “boom-boom” call invites other monkeys to come toward the male making the sound. Two booms can be combined with a series of “krak-oos”, with a meaning entirely different to that of either of its single parts. “Boom boom krak-oo krak-oo krak-oo” is the monkey’s version of “Timber!” – it warns of falling trees.

If Zuberbuhler is correct, the Campbell’s monkeys can both vary the meaning of specific calls by adding something and combine calls to make a different meaning.

Dear Mr. Barton,
I am writing for the residents’ association (业主协会) to inform you of our feelings about your act. We’ve really had enough of you. Although we have tried to speak to you politely on several occasions, you have always answered with a stream of verbal abuse(辱骂).
Ever since you moved in three months ago, you have shown very little consideration for the other residents of this building, though many residents expressed their unhappiness with you. For the past six weekends, you have held very noisy parties, which have not finished until early the next morning. As you know, most of the people here are elderly or have very young children, and the noise keeps them awake all night. You don’t have to be so noisy, do you? Last weekend the situation deteriorated when two of your friends fought with each other on the first floor. The fighting was so bad that the police had to be called. What’s more, your friends left the stairs in a terrible state --- they even broke two windows on their way out! We feel that we can’t bear this type of act.
We strongly demand that you pay for this damage to the window soon. If you don’t and you carry on being a nuisance(令人讨厌的人或物). We will kick you out! Legal steps will be taken if necessary.
Yours sincerely,
Resident
