82.(28855-!-item-!-188;#058&004055)

In a blow to those who still harbored the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick for enabling an interloper to rig an E-mail message so that this person will be privy to any comments that a recipient had added as the message is forwarded to others or sent back and forth.

(A) who still harbored the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick for enabling an interloper to rig an E-mail message so that this person will be privy to any comments that a recipient had added

(B) who had still been harboring the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick for enabling an interloper to rig an E-mail message so that this person was privy to any comments that a recipient might have added

(C) who still were harboring the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick enabling an interloper to rig an E-mail message so that this person is privy to any comments that a recipient would add

(D) still harboring the illusion that E-mail exchanges are private, a watchdog group recently uncovered a trick that enables an interloper to rig an E-mail message so that this person will be privy to any comments that a recipient might add

(E) still harboring the illusion that E-mail exchanges had been private, a watchdog group recently uncovered a trick that will enable an interloper to rig an E-mail message so that this person was privy to any comments that a recipient might add

我选的C，prep笔记里说who still were 应该被省去，为什么啊~~those who读上去好顺啊。。。还有后半句实在不理解意思。。。求解释啊~~~~~

生词汇太多了。。。
those后面的修饰语说的是那些（those）沉浸在对邮箱交流是私人的幻想中的人。
并不是说“过去沉浸，现在不沉浸”的人，而是说，一直沉浸在幻像中的人，是不是该工现在分词呀
后面的意思不重要，大体说一个杀毒软件？还是什么的发现了一些黑客用钓鱼软件做坏事，看懂enable就行了

个人认为：
1：本句子意思：为了让那些以为用E-mail交换信息很安全的人认识到这是个幻想，一个调查组最近揭发了一个手法，这个手法可以让信息偷窥者操纵 E-mail 信息，这样信息偷窥者就可以在信息输入人在发送给他人或收到他人回信的过程中获得这些信息。

2：A、B选项中for enabling 是错误的表达，此处用状语修饰trick，再说就算是表达目的也应该用to enable。E选项中will do的时态错误。C选项中，前半句中没有表达过去一直在进行的意思，所以不用those who were。。。。。而正确选项D则用了分词来对those进行修饰说明，其他部分也正确，故选D。
