[求助]大全693题

1.        The Audubon Society and other conservation groups, concerned over what they have perceived to be the serious threatening of the environment as posed by the policies of the government, are preparing for a major political effort.

(A) have perceived to be the serious threatening of the environment as

(B) perceived as the serious threat to the environment as

(C) perceive being the serious threat to the environment

(D) are perceiving as the serious threatening of the environment（E）

(E) perceive as the serious threat to the environment

请问这句话是什么意思？percieve后面的as干什么用，posed by又是修饰谁的？

谢谢！

what=the thing that

They perceive (the thing) as the threatening posed by the policies.

sb perceive A as B = A sb perceive as B 倒装结构

posed by修饰threat

第二次再看这题时，发现自己对perceive和pose这两个词的意思根本没理解透，所以才会不明白。

Longman Dictionary:

per‧ceive [transitive not in progressive]
1) written  to understand or think of something or someone in a particular way
perceive something/somebody as something
Even as a young woman she had been perceived as a future chief executive.
perceive something/somebody to be something
Often what is perceived to be aggression is simply fear.    Children who do badly in school tests often perceive themselves to be failures.

pose
1 ▶CAUSE PROBLEM◀
[transitive] to exist in a way that may cause a problem, danger, difficulty etc
pose a threat/danger/risk   Officials claim the chemical poses no real threat.
pose something to/for somebody/something
The events pose a challenge to the church's leadership.    Rising unemployment is posing serious problems for the administration.

posed by修饰threat,会不会造成歧异修饰enviroment啊？

Audubon 社团和其他自然保护团体，对由于政府政策所产生的严重环境威胁很关心，正在准备采取政治行动。

what= the thing that.

the subordinate clause is equal to "that they perceive (the thing) as the threatening posed by the policies."

"posed by" modifies "threatening"

这到题我也觉得POSED有修饰ENVIORNMENT的嫌疑呀，

一般说跳跃修饰中心词修饰词前面都有逗号，紧跟着的分词都是修饰它前面的那个词呀。所以我觉得这里POSED有修饰ENVIRONMENT的嫌疑呀！

指点呀，牛牛们！

pose 1 ▶CAUSE PROBLEM◀ [transitive] to exist in a way that may cause a problem, danger, difficulty etc pose a threat/danger/risk Officials claim the chemical poses no real threat. pose something to/for somebody/something The events pose a challenge to the church's leadership. Rising unemployment is posing serious problems for the administration.

如果理解了pose的含义，就不会觉得"posed"有修饰歧义了
