6.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) perceive as the serious threat to the environment 答案E。我想问如果B的perceived表示这些group过去的行为这样行吗？因为题目本来要把这些groupconcerned over what+威胁环境的内容与这些posed by the policies of the governme的威胁内容相比较的（题目有2个as ...as） 现在E中去掉了,意思就变了.这样如果B中的过去试可以说得过去,那么是否选B较好呢?
D: The Audubon Society and other conservation groups, concerned over what they perceive as the serious threat to the environmentposed by the policies of the government, are preparing for a major political effort.
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 大概就是因为这个are
我觉得这里concerned over...并不是过去时态，而是who are concerned over....省略了who are.
