Nature’s cheats Mary is di

Nature’s cheats Mary is digging in the ground for a potato, when along comes John. Seeing that there is no one in sight, John starts to scream. John’s angry mother rushes over and drives Mary away. Once his mum has gone, John helps himself to Mary’s potato. We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him. But Mary and John are not humans. They’re African baboons(狒狒). 71 John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others. 72 Studying behavior like this is complicated, but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated. 73 An ape was annoying him, so he tricked her into going away by pretending he had seen something interesting. When she found nothing, she “walked back, hit me over the head with her hand and ignored me for the rest of the day.” Another way to decide whether an animal’s behavior is deliberate is to look for actions that are not normal for that animal. A zoo worker describes how an ape dealt with an enemy. “He slowly stole up behind the other ape, walking on tiptoe. When he got close to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe. 74 But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as * copying. It seems that trickery does play an important part in ape societies. 75 Studying the intelligence of our closest relative could be the way to understand the development of human intelligence. A. In most cases the animal probably doesn’t know it is cheating. B. An amusing example of this comes from a psychologist working in Tanzania. C. And playing tricks is as much a part of monkey behavior as it is of human behavior. D. So the psychologists asked his colleagues if they had noticed this kind of trickery. E. The ability of animals to cheat may be a better measure of their intelligence than their use of tools. F. This use of a third individual to achieve a goal is only one of the many tricks commonly used by baboons. G. Of course it’s possible that it could have learnt from humans that such behavior works, without understanding why.

解题过程：
71:C
72:F
73:B
74:G
75:E
71:考查句意理解和上下文串联，根据上文：We’ve all experienced similar annoying tricks when we were young—the brother who stole your ball and then got you into trouble by telling your parents you had hit him.可知：和人一样玩诡计对猴子来说是一部分，答案是C
72:考查句意理解和上下文串联，根据上文：John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later seen playing the same tricks on others.可知：用另外一个人来得到目标只是狒狒使用的常见的诡计之一。答案是F
73:考查句意理解和上下文串联，根据上文：but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themselves had been cheated.可知：这个有趣的例子是来自于坦桑尼亚的一个心理学家的工作，答案是B
74:考查句意理解和上下文串联，根据下文：But looking at the many cases of deliberate trickery in apes, it is impossible to explain them all as simple copying.可知：可能它是从人类身上学会这个方法是有用的，但是不理解为什么，答案是G
75:考查句意理解和上下文串联，根据下文：Studying the intelligence of our closest relative could be the way to understand the development of human intelligence.可知：动物欺骗的能力比使用工具更能够衡量它们的智力。答案是E
最终答案：已给
