tania mm,我进度比你慢,做的题目是无重复的,跟你不一样,所以这两天都没参加讨论.

不过我有些问题想请教,可以贴在你这里吗?

我今天开始做GWD06,也就是XY04,比tania慢多了

最近也是阅读不行,老是错5个 所以还是先来阅读的题目吧.

呵呵,积累的问题太多,先贴GWD1的好了.

Over the last 150 years, large

       stretches of salmon habitat have

       been eliminated by human activity:

Line       mining, livestock grazing, timber

  (5)      harvesting, and agriculture as well

as recreational and urban devel-

opment.  The numerical effect is

obvious:  there are fewer salmon

in degraded regions than in pris-

(10)      tine ones; however, habitat loss

also has the potential to reduce

genetic diversity.  This is most

evident in cases where it results

in the extinction of entire salmon

(15)      populations.  Indeed, most

analysts believe that some kind

of environmental degradation

underlies the demise of many

extinct salmon populations.

(20)      Although some rivers have

       been recolonized, the unique

       genes of the original populations

have been lost.

      Large-scale disturbances in

(25)      one locale also have the potential

to alter the genetic structure of

populations in neighboring areas,

even if those areas have pristine

habitats.  Why?  Although the

(30)      homing instinct of salmon to their

natal stream is strong, a fraction

of the fish returning from the sea

       (rarely more than 15 percent)

stray and spawn in nearby

(35)    streams.  Low levels of straying

are crucial, since the process

provides a source of novel

genes and a mechanism

      by which a location can be

(40)     repopulated should the fish

there disappear.  Yet high rates

of straying can be problematic

because misdirected fish may

interbreed with the existing stock

(45)      to such a degree that any local

adaptations that are present

become diluted.  Straying

rates remain relatively low when

environmental conditions are

(50)      stable, but can increase dramati-

cally when streams suffer severe

disturbance.  The 1980 volcanic

eruption of Mount Saint Helens,

for example, sent mud and debris

(55)      into several tributaries of the

Columbia River.  For the next

couple of years, steelhead trout

(a species included among the

salmonids) returning from the

(60)      sea to spawn were forced to

find alternative streams.  As

a consequence, their rates of

straying, initially 16 percent,

rose to more than 40 percent

(65)      overall.

      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.  Such a dra-

(75)      matic increase in straying from

damaged areas to more pristine

streams results in substantial

gene flow, which can in turn lower

the overall fitness of subsequent

generations.

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.

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?

vacationer

以下是引用tania在2005-9-1 18:24:00的发言：

欧觉得从第一段可以看出supplier partnerships是针对那些indirect 的purchase来讨论的，D选项中的when the goods or services provided are directly related to the purchasers’ end products已经超出了原文讨论的范围，所以不能从原文中infer出来。不知对否？

恩,我大概知道了,唉,前两天做的居然都不怎么记得了,看了两三遍才明白

以下是引用tania在2005-9-1 19:03:00的发言：

我觉得应该选B。因为原文中k反驳m的观点基于三方面：一是在没有人捕猎的地方那些大的动物也灭绝了（红色部分）；二是除了那些大动物之外，有一些小的人们不消费的动物（not all）也灭绝了（绿色部分）（前两个观点说明也许不是人类的捕食造成了动物灭绝）；三是通过说明气候变化确实发生了来驳斥m认为气候不能作为解释动物灭绝的原因（蓝色部分）。

B选项是对k的第二个观点进行的反驳，指出人们其实都是吃这些小动物的，没有人们不吃的小动物

C选项不能作为削弱，如果是削弱的话，应当说明气候没有发生变化，而C选项承认了确实发生了气候的变化，只是把时间扩展了，说以前和以后也发生了气候变化，但他并没有削弱发生气候变化这个事情。

所以我认为C不对。

请拍砖

同意B. 我现在觉得阅读其实就是一篇大逻辑

昨天做了XY版的GWD6, 有两个问题.

Q14:

Political Advertisement:
Mayor Delmont’s critics complain about the jobs that were lost in the city under Delmont’s leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont’s tenure the average paycheck in this city has been getting steadily bigger.

Which of the following, if true, most strengthens the argument in the advertisement?

1. The average pay for jobs created in the city during the past three years was higher than the average pay for jobs created in the city earlier in Mayor Delmont’s tenure.
   
2. Average pay in the city was at a ten-year low when Mayor Delmont took office.
   
3. Some of the jobs created in the city during Mayor Delmont’s tenure have in the meantime been eliminated again.
   
4. The average pay for jobs eliminated in the city during Mayor Delmont’s tenure has been roughly equal every year to the average pay for jobs citywide.
   
5. The average pay for jobs in the city is currently higher than it is for jobs in the suburbs surrounding the city.

这道题答案是D,我觉得D相对来说是很好,但是题目问的是strengthen, 我怎么觉得D更象是assumption呢?

Q34:

The market for recycled commodities like aluminum and other metals remain strong despite economic changes in the recycling industry.

1. commodities like aluminum and other metals remain


2. commodities like those of aluminum and other metals are remaining


3. commodities such as aluminum and other metals remains


4. commodities, such as aluminum and other metals, remain


5. commodities, like the commodities of aluminum and other metals, remains

这题C是不是改成commodities, such as aluminum and other metals, remains比较好啊?

vacationer

以下是引用liu977在2005-9-2的发言：

个人觉得那样不对，因为改成commodities, such as aluminum and other metals, remains以后，就便成such as 修饰the market 了，这里是特意将such as 与commondities相连以避免歧异，这点和V-ing的位置关系有些相似。

恩,你说的对, 我没有想到这一点,就是没有逗号好像觉得看上去有点不习惯

GWD7-04

Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings.

A.      movies—less than those

B.       movies—fewer than have been

C.       movies, which is less than those

D.      movies, a number lower than the people

E.       movies, fewer than the ones

怎么我觉得没有一个是对的

B中的 have been 之前不用加those之类的词吗?
