提供一比較標準來與"須被衡量的(對鮭魚群間流動基因衝擊的)人類活動"相比

GWD-1-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

選C應該沒問題


Q12 我選B
在CD 也有長篇討論過這題 不過似乎也沒明確結論

why I favor (B):
最後一段
Although no one has quantified
changes in the rate of straying
as a result of the disturbances
caused by humans, there is no
reason to suspect that the effect
would be qualitatively different
than what was seen in the
aftermath of the Mount Saint
Helens eruption.


再往回看原提及 eruption of Mount Saint Helen ( 52行)
是來說明straying rates can increase dramatically when streams suffer severe disturbance.

而straying rates 是在說明 ( 第二段開頭 )
Large-scale disturbances in one locale also have the potential
to alter the genetic structure of populations in neighboring areas,


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

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

# a standard of comparison : 原文只提及there is no reason to suspect that .. 還不到成為 standard
# should be measured : 原文只提及 Although no one has quantified ...
雖然.... 但作者也沒說should be measured

我補充一下選B的原因:
這篇文章依旨趣分為三部份:
第一部份講 人類活種的影響L1-15
第二部分 講 環境因素對類近地區魚群的影響L15-65
第三部分 回頭講人類活動也會和環境因素一樣,對周圍魚群的生態造成影響。L65-79
首先 這題是在第三個部份提問,亦即在強詷人類活動也會和環境改變一樣,對過邊的魚群造成影響。其次, in the aftermath of the Mount Saint Helens eruption就是在說明裝境改變對周邊魚群的影響,很顯然,這個例子擺在這裡,就是要說,人類活動的影響(雖然還沒有被證實),和這個(the aftermath of the Mount Saint Helens eruption)情況,不會差太遠!
請大家參考!

我也選b說

排除c的原因與gogotu大一樣,覺得文章沒有說要把eruption作為一個衡量的標準
僅僅說 人類活動對魚的影響和eruption對魚的影響 推測是差不多的(no reason to suspect )

選B的因素,是覺得本段的用意就是要說明人類活動會跟第二段題到的eruption一樣會造成魚群的相似的影響,所以提到the aftermath of the Mount Saint Helens eruption也是為了指出人類活動會造成怎樣的影響。

如果要選C感覺還解釋的過去(雖然心裡還是有點小小的疑問),但想請問B的明顯錯誤在哪裡哩~~~請各位大大指教

新手,嘗試解答~
你的問題是不是,
(1)against the impact of human activity
or
(2)against which the impact of
human activity on the gene flow among salmon populations
should be measured 這整句話

我覺得是(1)
老莫說的,介係詞加關代 aginst which
which是代名詞,代名詞,不可以帶句子!!!
所以against是against the impact.

翻成中文就是,提供一個比較標準來反對人類活動對鮭魚人口gene flow的影響,而這影響是需要被衡量的!!!

agk99 \$m[1]:
GWD-1-Q10:
It can be inferred from the passage that the occasional failure of some salmon to return to their natal streams in order to spawn provides a mechanism by which

A. pristine streams that are near polluted streams become polluted themselves (文章沒有這種暗示)
B. the particular adaptations of a polluted stream’s salmon population can be preserved without dilution (剛好相反)
C. the number of salmon in pristine habitats decreases relative to the number in polluted streams 
D. an environmentally degraded stream could be recolonized by new salmon populations should the stream recover
E. the extinction of the salmon populations that spawn in polluted streams is accelerated 

(文章若能仔細review一次,應該可以選出D)
GWD-1-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



關於第十題,請問是不是由
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.


看出的呢?


而關於第十二題,我比較支持C,
理由和twkevin相同,也是由最後一段
Although no one has quantified
changes in the rate of straying
as a result of the disturbances
caused by humans, there is no
reason to suspect that the effect
would be qualitatively different
than what was seen in the
aftermath of the Mount Saint
Helens eruption.

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

兩個同樣都有提到可能改變gene,但是A的說法比較保守,而我覺得B的答案最後should be measured 由文中無從得知。

再討論囉!!!

老莫貝貝說代名詞不可代替句子,應該僅限於修辭部份
事實上which是可以代替一整個概念的∼他在專題就會講到了
基本上
我同意大衛大大的解說
against 做 "對比、比照" 之意
e.g.,He checked the contents of the box against the bill.

請大家參考!



我原來選(B),但現在看完整個討論以後,覺得(C)應該才是對的
第一段說明人類活動的影響時,提到兩個部分:1. salmon 數量減少 2. genetic diversity reduced
第二段是在說明 環境因素如何 reduce genetic diversity,並用 the eruption of Mt. Saint Helen 做例子
第三段又說:雖然目前沒有人為造成genetic diversity "quantity" changed 的資料,但 author 認為 "quality" 上無從置疑。

所以(B)�的 to the "extent" 指的就是 "quantity" ,這方面還沒有數據,如何能 "indicate"?就算是指"quality",author 也只說 "no reason to suspect",並未 "indicate" 任何東西。相反的(C)說 provide a standard 暗指第三段所說,quality上 no different,所以可以在 quality 上比較。故 provide a standard 應該沒什麼問題。
