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.

答案是D,这题没什么头绪，麻烦大家帮忙分析一下其他各项的错处，谢谢！

高广的地方是大概的错误地方，总之这道题的考点就是

1、未划线部分没有给出任何关于特殊时态的时间状语，句子当中最好就不要出现。比如过去完成时，以及各种进行时，都算是比较特殊的时态。

2、定语从句和分词的使用：当定语从句可以表示出分词不能表示的意思时（包括时态，语气等），使用从句，否则使用分词。这道题harboring和enabling 都可以使用分词，但是A,B中的那个for enabling就是错的。

还有什么问题回帖哈
