Even more than mountainside slides
of mud or snow, naturally occurring forest
fires promote the survival of aspen trees.
Line Aspens’ need for fire may seem illogical
(5) since aspens are particularly vulnerable
to fires; whereas the bark of most trees
consists of dead cells, the aspen’s bark
is a living, functioning tissue that—along
with the rest of the tree—succumbs quickly
(10) to fire.
The explanation is that each aspen,
while appearing to exist separately as
a single tree, is in fact only the stem or
shoot of a far larger organism. A group
(15) of thousands of aspens can actually
constitute a single organism, called a
clone, that shares an interconnected root
system and a unique set of genes. Thus,
when one aspen—a single stem—dies,
(20) the entire clone is affected. While alive,
a stem sends hormones into the root
system to suppress formation of further
stems. But when the stem dies, its
hormone signal also ceases. If a clone
(25) loses many stems simultaneously, the
resulting hormonal imbalance triggers a
huge increase in new, rapidly growing
shoots that can outnumber the ones
destroyed. An aspen grove needs to
(30) experience fire or some other disturbance
regularly, or it will fail to regenerate and
spread. Instead, coniferous trees will
invade the aspen grove’s borders and
increasingly block out sunlight needed by
the aspens.



Q36:
It can be inferred from the passage that when aspen groves experience a “disturbance” (line 30), such a disturbance

A. leads to a hormonal imbalance within an aspen clone
B. provides soil conditions that are favorable for new shoots
C. thins out aspen groves that have become overly dense
D. suppresses the formation of too many new aspen stems
E. protects aspen groves by primarily destroying coniferous trees rather than aspens

我想請問一下這題 麻煩強者解答一下!!!!謝謝

hello , 這道題我會選B

答題的依據是 An aspen grove needs to
(30) experience fire or some other disturbance
regularly, or it will fail to regenerate and
spread

wish it's useful :)

可是答案是A 怪怪 我也覺得A不對

[魚]

頂一下 希望有人來幫忙 :D

我覺得我還是會選a說..

因為魚這句說到aspen要fire或其他disturbance---否則無法再生...
那麼表示fire跟disturbance是好的

前面又說到 the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed

表示imbalance是造成regenerate的原因

所以選a

請多多指教...

嗯 這樣我懂了 轉了個彎!!!!! 謝謝 魚 和 Behemoth

唉呀,快別這麼說了,搞的跟成語比賽一樣...我都不好意思了 :-$

這題是因為那時在準備的時候想了很久,後來才懂的

GWD-5-Q37: A
The author of the passage refers to “the bark of most trees” (line 6) most likely in order to emphasize the

A. vulnerability of aspens to damage from fire when compared to other trees
B. rapidity with which trees other than aspens succumb to destruction by fire
C. relatively great degree of difficulty with which aspens catch on fire when compared to other trees
D. difference in appearance between the bark of aspens and that of other trees
E. benefits of fire to the survival of various types of trees


請教為何選A

本題是推論題，答案應是由本文所推出，為什麼不是由第二段最後一行所推出的，因為coniferous trees will
invade the aspen grove’s borders and
increasingly block out sunlight needed by
the aspens.
所以推得，Such a disturbance protects aspen groves by primarily destroying coniferous trees rather than aspens

請各位大大提供意見！

[wangdaven]

我選(A)
disturbances不一定是primarily destroying coniferous forest的吧? 文章沒有明確提到說disturbances是什麼東西,我們不需要幫他想像,如果文章指涉的是fire呢? 相較之下,fire或disturbances會促進aspen生長,而文章也提到促進生長的因素會經過hormonal imbalance這個程序,推論下來,這兩者都必然要造成aspen有hormonal imbalance的情形,文章的事實才能成立

Q35:
The primary purpose of the passage is to explain the

A. qualities that make a particular organism unique
B. evolutionary change undergone by a particular organism
C. reasons that a phenomenon benefits a particular organism
D. way in which two particular organisms compete for a resource
E. means by which a particular organism has been able to survive in a barren region

想請教一下A為什麼不行呢，這篇文章是不是主要在強調此物的特殊性及解釋獨特性產生的原因？？
此外，我也不明白C選項中，phenomenon benefit是在強調什麼耶！！麻煩大家幫我解惑一下，謝謝拉！！

我想文章的第一段指出了一個矛盾
一般而言，森林大火應該是有害樹的生長，
為何白楊樹反而因而獲益?

你所說的phenomenon就是指 forest fire

(A)答案僅侷限在第二段的內容，相較C來的SPECIFIC，
而且文章的目的並不僅限在解造成白楊樹的特質，
而是在解釋看似矛盾的因果關係，因此(C)會相對範圍比較大，共您參考.
