Mary is digging in the ground for a photo, 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 himlf 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). ___小题1:___John’s scream and his mother’s attack on Mary could have been a matter of chance, but John was later en playing the same tricks on others. ___小题2:___Studying behavior like this is complicated but scientists discovered apes(猿) clearly showed that they intended to cheat and knew when they themlves had been cheated. ___小题3:___ An ape was annoying him, so he tricked her into going away by pretending he had en 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 clo to his enemy, he pushed him violently in the back, then ran indoors.” Wild apes do not normally walk on tiptoe. ____小题4:___ But looking at the many cas of deliberate trickery in apes, it is impossible to explain them all as simple copying.It ems that trickery does play an important part in ape societies. ____小题5:___ Studying the intelligence of our clost relative could be the way to understand the development of human intelligence.A．In most cas 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 u of toolsF. This u of a third individual to achieve a goal is only one of the many tricks commonly ud by baboons.G. Of cour it’s possible that it could have learnt from humans that such behavior works, without understanding why. 题型：未知难度：其他题型

解析

文章介绍了一项调查发现，和人一样，动物有时也会玩鬼。小题1: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小题2: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 en 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小题3: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 themlves 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小题4:考查句意理解和上下文串联，根据下文：But looking at the many cas 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小题5:考查句意理解和上下文串联，根据下文：Studying the intelligence of our clost 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

考点

据考高分专家说，试题“Mary is digging in t.....”主要考查你对 [序数词 ]考点的理解。 序数词

序数词的概念：

表示顺序的数称为序数词。如：first, cond, third, fourth。

序数词的构成与用法：

1、序数词的构成：①一般来说，是由相应的基数词加词尾th构成。   例：four＋th→fourth   six＋th→sixth    ven＋th→venth   ten＋th→tenth②下面这些基数词在变为序数词时，有特殊的变化。例：one→first    two→cond    three→third    five→fifth    eight→eighth    nine→ninth    twelve→twelfth③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。例：twenty→twentieth    thirty→thirtieth    forty→fortieth    ninety→ninetieth④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。例：twenty－one→twenty－first    thirty－five→thirty－fifth    a hundred and fifty－three→a hundred and fifty－third2、序数词的用法：①序数词在使用时，一般加上定冠词。例：the first book    the cond floor    the third day    the fourth week．②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。例：The may1st is Labour Day. 五月一日是劳动节。    My room is on the cond floor. 我的房间在二楼。    The first is larger than the con.（主语）第一个比第二个大。    Read the book from the first.（宾语）从开头读这本书。    You'll be the sixth to write.（表语）你将是第六个写的。③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。例：You may have a third try. 你可以第三次尝试。

序数词知识体系：

 

约数的表达方法：

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。 如：The boy bought dozens of pencils.       Thousands of people died in the earthquake. 注意： (A)：dozen, score, hundred, thousand, million等表示确切数量时，不用复数。 如：five dozen (of) eggs   五打鸡蛋    hree hundred people  三百个人

分数词的构成和用法：

1）分数词构成法：分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：如：1/4：one-fourth    5/9：five-ninths    2/3：two-thirds   17/5：three and two-fifths   7/12：ven-twelfths   379/8：forty-ven and three-eighths此外还有下面表示法：如：1/2：a(one) half    1/4：a(one) quarter    3/4：three-quarters    9/4：two and a quarter    3/2：one and half     31/4：ven and three quarters
