看完讨论迷糊了：再问og10-222

By a vote of 9 to 0, the Supreme Court awarded the Central Intelligence Agency broad discretionary powers enabling it to withhold from the public the identities of its sources of intelligence information.

(A)  enabling it to withhold from the public

(B)  for it to withhold from the public

(C)  for withholding disclosure to the public of

(D)  that enable them to withhold from public
    disclosure

(E)  that they can withhold public disclosure of答案选对乐A，

可是看了版上的讨论以后，越发糊涂了。想请问问NN们，A和B的区别。我自己认为，后面的its表明了前面的it是指代CIA的，A侧

重于修饰powers，说明powers施与CIA那个权利，可是B不也能这么翻译吗？难道是区别在于B的重点放在了TO以后的目的性？而A

侧重于给于这个权力？不知道我说明了没有。

FOR与名词、代词、不定式连用，组成不定式复合结构：

They made way for the car to pass. 他们闪开让汽车过去。

Here are some books for them to read. 这儿有几本书可以让他们看。

There is no need for anyone to know. 没有必要让谁都知道。

They made way for the car to pass. 他们闪开让汽车过去。

Here are some books for them to read. 这儿有几本书可以让他们看。

There is no need for anyone to know. 没有必要让谁都知道。

award someone sth for someone to do sth,太冗长了

要不award someone sth,要不就是 award sth to someone

然后，enabling直接修饰power,最简洁，标明施动关系
