Inspired by the Helsinki Accords and outraged by the harsh sentences meted out to a group of Czech rock musicians called the Plastic People of the Universe, Charter 77 was established by dissident writers, philosophers, and other professionals to be a human rights group.
Charter 77 was established by dissident writers, philosophers, and other professionals to be
Charter 77 had been established by dissident writers, philosophers, and other professionals as
Charter 77, established by dissident writers, philosophers, and other professionals, was
dissident writers, philosophers, and other professionals established Charter 77 as

还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
补充：如果使用过去完成时，就会暗含在过去的过去的一段时间里，这些人把它看作是human rights group, 而过了这个过去的时间之后就不会被人这样认为了，e选项改变了句意。
主谓不一致排除abc；
根据helr老师的约束力原则，establish这个动作约束力弱，不会对charter 77 造成任何改变，所以不用不定时
同理think of ... as ... 而不用to be
DE 二选一错了 时态 没把握好 应该是 先激励 再 建立 我以为是过去的过去....
inspired修饰的主语是人，所以排除ABC，DE中，只有时态有区别，叙述过去的事实，所以过去时
Inspired逻辑主语应该为人，ABC排除，E，过去完成时，错误
inspired and outraged 都要修饰人，所以ABC排除。DE中，是先被激怒，再才创建，而E搞反了，established用的过去完成时。选D
inspired 和outraged 的主语应该是人
The idiomatic expression established . . . as is preferable
to the nonstandard and somewhat unclear established . . . to be.
