AA: 31. The following appeared as part of the business plan of an investment and financial consulting firm.

“Studies suggest that an average coffee drinker’s consumption of coffee increases with age, from age 10 through age 60. Even after age 60, coffee consumption remains high. The average cola drinker’s consumption of cola, however, declines with increasing age. Both of these trends have remained stable for the past 40 years. Given that the number of older adults will significantly increase as the population ages over the next 20 years, it follows that the demand for coffee will increase and the demand for cola will decrease during this period. We should, therefore, consider transferring our investments from Cola Loca to Early Bird Coffee.”

AI:100. “If a nation is to ensure its own economic success, it must maintain a highly competitive educational system in which students compete among themselves and against students from other countries.”

MATH:基本全是JJ.为了控制不要点的太快,一直在看秒表.请大家注意确认答案,遇到几到不确定答案的题,考前没时间弄透它,结果考试的时候还是遇到了.

1.N+19 是N+3的倍数,问有几个这样的N?(3)

2.x^2+ax+b=0,如果有两个正根，下面哪项是能够得出的（a<0,   ab<0）

3.已知任意三点，求三角形面积．用二点式求出三边距离，可得直角三角形．（答案１／２＊根号１１６＊根号２９）

３．哪个数有七个质因子．（６４）

都重复，就不写了．

ＲＣ：１，上来就遇到只有一句话的ＪＪ环境资源定价，完全没读懂是什么意思，到最后也没明白，完全糊涂，（ＲＰ按说不错啊，估计就坏在这篇阅读了，没办法）：　来回讲三个人的观点（注意定位三个人的名字），关于ecosystem和economic value, 有的专家说ecosystem．．．（有考题，非常不好选，）另一个专家大意是说说通过旅游资源可以有收入，能保护森林啊什么的．．．．．文章不长，但句意理解困难．

２．加拿大铁路发展ＤＥＬＡＹ那篇，文章ＪＪ很清楚了，也没有生词．有一题是：哪一个选项能够削弱作者对于发展滞后的解释．（基本上是作者的几个解释的变形，我选了天气变化使得ＣＲＯＰ的收获周期变长，有点怪，不确定）

３，大脑智力发展（有一题是问从文章中能推理出neanderthals能够做什么，文章中neanderthals只出现了一次，所以选项不好对应，大家仔细推吧，其中一个选项是neanderthals在４０００年前就发展智力了，另一个选项是neanderthals那个年代就有人带项链，在皮肤上画画，．．．）

４，考古中的科学定年法．文章不难．Ｃ１４方法不能解决一些问题年代过久的东西的年代测定，因为样本数量太少（有一题是问新方法的特点，答案是有sufficient 的样本）．另一个方法，能够解决这些问题，而且还有其它的一些有用的作用．有主题题，一个新的方法的应用及潜在价值．

ＣＲ：

１．稀有植物和大量存在的非称有植物相比，反而寿命比较长，不管各个地区的湿度，气候，火灾之类的原因，问哪个选项能够解释这个原因．（我选了大火对这种植物的破坏相对较小，很不确定）

这是ＪＪ，但我觉得那个长得好象不象，没有讲鸟，就是讲植物

是关于rare species & common species of bird

说在赤道地区rare species 比common ones tend to live longer, while regardless the wet environment or frequent fire. 问解释

答案都很离谱：

有一个选项有说到因为fire,可是显然上面说了跟fire没关系了都很好排除，但是最郁闷的是排除到最后剩下一道又臭又长的答案，看似无关，但是我也选了，因为其他的更胡闹

２，政府为了降低失业率，计划让所有的企业每周工作时间从３７减到３１，并且降低工资，这样企业就不得不雇用更多的员工，但是实了际上政府的税收并没有比想象得少很多，问解释．（Ａ：一些企业不会采取这个措施，Ｂ：企业减少工作时间，但是不降工资，还是不减少工作时间，但是会减工资，晕了，Ｃ：新增加的员工也要纳税．．．）

３．公司经理说要在室内装个什么设备，因为暴风雨中能够产生某种离子之类的东西对身体有益，安装了这个东西也会．．．．．问削弱．

４．只记得一道：说sales那奖励，一个是现金奖另一个是旅游奖，结果发现那现金奖的人里大部分都觉得奖金给少了，而拿旅游奖的人大部分都觉得给的还可以，问题是为什么那现金奖的人虽然觉得给少了但还是选择了现金。

A. 如果那现金奖的人觉得自己有时间去旅游的话他也会选择旅游奖的

５， 某个冬冬把地球被撞了一下后，地球的碎片形成了月球。但是另外一个星球，跟地球的情形差不多，为什么没有个月亮绕着转呢？其实那个星球本来有个小月亮的，但是后来再次被撞，这次碰撞改变了这个星球的重力系统，吸引不住小月亮，于是小月亮就丢到太空里了。问assumption.

我选的是：假设这个东西的碰撞不会形成一个新的月亮或者形成的新月亮也丢到太空里了。

６，Scientists typically do their most creative work before the age of forty.  It is commonly thought that this happens because   aging by itself brings about a loss of creative capacity.  However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual.  Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.

In the argument given, the two portions in boldface play which of the following roles?

A.                  The first is the position that the argument as a whole opposes; the second is an objection that has been raised against a position defended in the argument.

B.                  The first is a claim that has been advanced in support of a position that the argument opposes; the second is a finding that has been used in support of that position.

C.                 The first is an explanation that the argument challenges; the second is a finding that has been used in support of that explanation.

D.                 The first is an explanation that the argument challenges; the second is a finding on which that challenge is based.

E.                  The first is an explanation that the argument defends; the second is a finding that has been used to challenge that explanation.

注意：划线部分也是黑脸的，但是不影响结果

答案依然是D，答案本身稍有修改，但是不影响结果
