搞不懂为什么M不是51,感觉大多数题目都很傻,就5道值得一题.
1. x个数的和比它们的平均数多百分之多少?(我呆2分钟,感觉好奇怪)
    解: Sum/(Sum/x)-1=100(x-1)%

2. n是大于1的整数,T是集合{k*n},其中k为所有整数.问n是多少?
    (1) -7是T中的一个
    (2)49是T中的一个
    解:选A,因为此时n=7,k=-1,不可能有其他解,而条件(2)可能得到n=7,k=7或n=49,k=1.

3. 总共30个东东,分5堆,每堆至少1个,问是否至少有一堆含9个以上(包括9个)这样的东东?
    (1)......忘了
    (2)有两堆每堆含2个这样的东东
   解:选B,因为此时另外3堆东东加起来有26个,如果这三堆每堆最多含8个,那么总数为24,小于26,所以至少有一堆含9个以上这样的东东.

4. 题意记不清了,反正简单的说,就是已知 p+s=N(p,s,N都是自然数),问N是多少?
   (1)p-1=0.2(N-1)
   (2)s-2=0.75(N-2)
解:选C(oh,my god!原来是这题错选了E,大家要引以为鉴啊!)
    三个未知数+三个方程,能解.结果p=6,s=20

5.已知mn<0,问(m^2 - n^2)^2?
  (1) (mn)^2=25
  (2) m-n=6(大概是6吧)
解:选C,因为根据(1)有mn=-5,根据(2)有m^2 - 2mn +n^2=36,于是m^2 + n^2 = 26, 结合(1)就能求得所求的值.

AA:Cafe 搬到一个新地方那篇
AI:performing public services不仅能benefit individuals,也能benefit country.

Verbal:
1.讲一个management model没被遵守,分析其原因,有公司并够和股权激励等等因素.
2.与elephant有关 ,第一段说elephant 减少了,于是有个ban出台,注意这个ban是针对trade的,而不是直接针对elephant的,第二段说有些国家要求突破这个ban的限制,分析了原因,其中之一是它们已经堆积了很多象牙奢侈品,需要卖掉从而获得资金来保护大象.
3.温室效应导致了若干结果, 不同的人持不同的看法.
4.GWD里的文章,可我时间不多了,已经没耐性看文章,随便选了选.(事实证明随便选总是错的)

There is no consensus among

researchers regarding what qualifies a

substance as a pheromone. While most

Line agree on a basic definition of pheromones

(5) as chemicals released by one individual

   of a species which, when detected by

   another individual of the same species,

   elicit a specific behavioral or physiological

   response, some researchers also specify

(10) that the response to pheromones must be

   unconscious. In addition, the distinction

   between pheromones and odorants—

   chemicals that are consciously detected

   as odors---can be blurry, and some

(15) researchers classify pheromones as a

type of odorant. Evidence that pheromone

responses may not involve conscious odor

perception comes from the finding that in

many species, pheromones are processed

(20) by the vomeronasal (or accessory olfactory)

    system, which uses a special structure in

the nose, the vomeronasal organ (VNO),

to receive chemical signals. The neural

connections between the VNO and the

(25) brain are separate from those of the main

olfactory system, whose processing of

odorants triggers sensations of smell. But

while the VNO does process many animal

pheromone signals, not all animal phero-

(30) mones work through the VNO. Conversely,

not all chemical signals transmitted via the

VNO quality as pheromones. For example,

garter snakes detect a chemical signal from

earthworms—one of their favorite foods—via

(35) the VNO, and they use this signal to track

their prey.

--------------------------------------------------------------------------------------------------

Q7

It can be inferred from the passage that

in classifying pheromones as a type of

odorant, the researchers referred to in

line 15 posit that

A.      pheromones are perceived

consciously

B.      most pheromones are processed

by the VNO

C.      most chemical signals processed

by the VNO are pheromones

D.      Pheromone perception does not

occur exclusively between mem-

bers of the same species.

E.       pheromones do not always elicit

a specific behavioral or physio-

logical response

answer:A

-------------------------------------------------------------------------------------------------------

Q8

According to the passage, the fact that

pheromones are processed by the VNO

in many animal species has been taken

as evidence of which of the following?

A.    The accessory and main olfac-

Tory systems are not separate

B.    Odorants and pheromones are

not distinct types of chemicals.

C.    Odorants and pheromones both

elicit a specific behavioral

response.

D.   Pheromones do not trigger con-

scious sensations of smell.

E.    Pheromones aid animals in track-

ing prey.

Answer

-------------------------------------------------------------------------------------------------------

Q9

The primary purpose of the pas-

sage is to

A.    compare and contrast the ways

in which the vomeronasal organ

and the main olfactory systern

process chemicals.

B.    summarize the debate over the

role the vomeronasal organ

plays in odor perception

C.    present some of the issues

involved in the debate over

what constitutes a pheromone

D.   propose a new definition of

pheromones based on recent

research

E.    argue that pheromones should be

classified as a type of odorant

Answer:E

SC: 感觉难度与Prep一致,有一道不确定:
   ...prompt __________ , doing... , and doing
选项里有 being thrify with sth, thriftiness of sth, being thrifty for sth, 还有两,但觉得不着边.
我不清楚是用with还是for,索性选了thriftiness.估计错了.

CR:有一题印象较深,迷糊中.
某公司五年来员工数量增加了,员工的效率也提高了,结果公司的productivity(定义为:总产量/总员工数)提高了. 结论是:虽然接下来的几年里,员工数量不变,但productivity会提高.
问下面哪个是对的?(即问结论)
A:无关比较(与其他公司相比blahblah...)
B:员工的工作时间会增加
C:员工的工资会增加
D:忘了
E:接下来几年里,productivity增加的速率(rate)比过去五年要低
反正感觉没一个对的,随便选了.

最后,我要说,机经只是起到辅助作用,不能拿来压宝.(我最后一篇复习时全对,但到考场上全错),关键还是要自己看.
不管怎样,上700了,不想再考了,我已经倍受煎熬了...

恭喜杀鸡成功！
