以下是引用vacationer在2005-8-31 23:44:00的发言：

In corporate purchasing,

       competitive scrutiny is typically

       limited to suppliers of items that are

Line      directly related to end products.

  (5)     With “indirect” purchases (such as

computers, advertising, and legal

services), which are not directly

related to production, corporations

often favor “supplier partnerships”

(10)     (arrangements in which the

purchaser forgoes the right to

pursue alternative suppliers), which

can inappropriately shelter suppliers

from rigorous competitive scrutiny

(15)     that might afford the purchaser

economic leverage.  There are two

independent variables—availability

of alternatives and ease of changing

suppliers—that companies should

(20)     use to evaluate the feasibility of

       subjecting suppliers of indirect

       purchases to competitive scrutiny.

This can create four possible

situations.

(25)           In Type 1 situations, there are

many alternatives and change is

relatively easy.  Open pursuit of

alternatives—by frequent com-

petitive bidding, if possible—will

(30)     likely yield the best results.  In

Type 2 situations, where there

are many alternatives but change

       is difficult—as for providers of

employee health-care benefits—it

(35)   is important to continuously test

the market and use the results to

secure concessions from existing

suppliers.  Alternatives provide a

      credible threat to suppliers, even if

(40)    the ability to switch is constrained.

In Type 3 situations, there are few

alternatives, but the ability to switch

without difficulty creates a threat that

companies can use to negotiate

(45)     concessions from existing suppliers.

In Type 4 situations, where there

are few alternatives and change

is difficult, partnerships may be

unavoidable.

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

Q36:

Which of the following can be inferred about supplier partnerships, as they are described in the passage?

              

1. They cannot be sustained unless the goods or services provided are available from a large number of suppliers.
   



2. They can result in purchasers paying more for goods and services than they would in a competitive-bidding situation.
   



3. They typically are instituted at the urging of the supplier rather than the purchaser.
   



4. They are not feasible when the goods or services provided are directly related to the purchasers’ end products.
   



5. They are least appropriate when the purchasers’ ability to change suppliers is limited.
   

这道题前天看了讨论贴之后好像理解了,可是今天看了一下又不行了

D为啥错?

仅仅根据文张，推不出来D选项所说的东西；我们只能知道indirect的时候经常用partnership这种方式，但是推不出来这种方式是不是也适用direct的时候。这可能就是白痴原则吧。。。

而C明显我们可以从文中的afford economic leverage推出来。

以下是引用tania在2005-9-1 17:20:00的发言：

      Although no one has quantified

changes in the rate of straying

as a result of the disturbances

caused by humans, there is no

(70)      reason to suspect that the effect

would be qualitatively different

than what was seen in the

aftermath of the Mount Saint

Helens eruption.  

Q12:

The author mentions the “aftermath of the Mount Saint Helens eruption” (lines 73-74) most likely in order to

A.     provide an example of the process that allows the repopulation of rivers whose indigenous salmon population has become extinct

B.     indicate the extent to which the disturbance of salmon habitat by human activity in one stream might affect the genetic structure of salmon populations elsewhere

C.     provide a standard of comparison against which the impact of human activity on the gene flow among salmon populations should be measured

D.     show how salmons’ homing instinct can be impaired as a result of severe environmental degradation of their natal streams

E.      show why straying rates in salmon populations remain generally low except when spawning streams suffer severe environmental disturbance

答案是C,为什么B不对呢?好像这题也颇有争议.

我觉得这道题就是定位在上面这个部分，这里是用aftermath of the Mount Saint Helens eruption作为一个比较的对象，b选项的意思是“表明了disturbance of salmon habitat by human activity in one stream 可能影响其他地方salmon 的genetic structure的程度”与原文的比较无关啊

我也认为是这样的，这句话强调的重点不是B。

先汇报一下今天的情况，不好

gwd9  v  错了9个，其中sc 5

                        cr 1

                        rc  3

呵呵。非常好啊，不过SC有点多了。。。考试的时候可能前半部分的SC不少，谁知道呢。。。继续加油！

另外要注意时间，尽量在规定时间内完成。

1. Additional evidence indicating that widespread climatic change occurred not only at the end of the Pleistocene era but also in previous and subsequent eras                                                                       K认为：（at the end of the Pleistocenc）有climatic change ==> 有species extinction，前者导致后者                                             C选项：（in previous and subsequent eras）有climatic change ==>无species extinction，有因无果，削弱

好像不能这样理解哈。。。

如果在之前也有气候的变化，那么你能说明是climatic change at the end of the Pleistocene era导致灭绝的吗？也有可能是之前的气候变化导致的啊！

如果什么时候都有气候变化，那么这个因素应该排除，就像什么时候都有空气一样，你能说是空气导致的吗。。。

你这样说应该是同意C啊，因为一直有气候变化，所以气候变化这个因素应该排除，反驳K

以下是引用wwwhahchn在2005-9-1 20:40:00的发言：

哈哈，我也晕了。。

K认为那个纪末的气候变化是灭绝原因；C说之前之后也都有气候变化。

我以前是这样想的：之前之后有没有气候变化跟这次的大灭绝无关。。。呵呵

反正我也觉得这道题出得不好。

大家继续讨论！

tania

我觉得原文是k说这些植物、小动物等等中的一部分被人消费，还有一部分跟人没关系，而它们也灭绝了，所以用来反对m的理论，c选项是说这些植物、小动物其实全都跟人有关系，都被人使用了，所以削弱了k的说法。

wwwhahchn

哈哈，大家都晕了，tania237楼的帖子也把b写成了c

wwwhahchn

反正我觉得这题是典型的有因无果的削弱法

继续讨论

tania

刚刚楼下有人吵架，好烦，看来是晕了，竟然b、c写错了

还有，确实如ethyl说得，是得注意时间了，今天又超时12分钟。。。。。。

而且早上想试验一下，还喝了半罐红牛，明天再试试，也许这东西对我没什么用
