Question

To the untrained eye it might seem like just a bit of a monkey trick. But when Milly the mandrill (山魈, 西非洲產的大狒狒) covers her face with her hand she is actually sending a serious message to her fellows: “Leave me alone!”

Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space. And, surprisingly, the signal has been picked by other members of the group, who use it when they too require solitude.

Biologist Mark Laidre believes the behavior is evidence of social culture among the mandrills. Importantly, the sign language is unlikely to have been influenced by human activities because mandrills do not copy humans. Mr. Laidre expects further research will uncover other monkeys using cultural gestures — the ability to communicate with the hands in a meaningful way. “By covering their eyes with their hands, possibly conveyed to others that they wanted to be left alone and this message may have been respected as a ‘do not disturb’ sign,” said Mr. Laidre.

While the hand is in place, other monkeys are not likely to approach or touch the monkey. Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members. As the discovery appears to be unique to Colchester Zoo, it suggests it is a local phenomenon that arose naturally in the community of 25 mandrills.

Curator （園長） Sarah Forsyth said: “We believe Milly made up the signal and over the past five years some of the younger mandrills have picked it up. We’re not sure why she started doing it but it could be as simple as ‘I can’t see them, so they can’t see me’. It really does show you how intelligent mandrills are.”

【解析】

試題分析：

1.1】B主旨大意題。根據文章第二段第一句Experts believe the 15-year-old mandrill invented the gesture to warn other monkeys at Colchester Zoo to give her some space.專家認為這個十五歲的猴子發明了這個身勢，警告其他猴子給她一些空間。故選B。

2.2】A詞義猜測題。根據第二段最后一句surprisingly, the signal has been picked by other members of the group, who use it when they too require solitude.令人驚訝的是，信號已被其他組的成員所用，當他們太需要獨自的時候用它。故選A。

3.3】C細節理解題。根據地三段第二句Importantly, the sign language is unlikely to have been influenced by human activities最重要的是，這標志語言不可能受人類活動的影響。故選C。

4.4】A細節理解題。根據倒數第二段第二句Those who rank lower in the social order also use the technique to avoid attacks from more powerful group members.

5.5】D推理判斷題。根據倒數第二段中的As the discovery appears to be unique to Colchester Zoo,句意：這發現似乎是科爾切斯特動物園的獨特，從這里可知選D。
