In its 1903 decision in the case of Lone Wolf v. Hitchcock, the United States Supreme Court rejected the efforts of three Native American tribes to prevent the opening of tribal lands to non-Indian settlement without tribal consent. In his study of the Lone Wolf case, Blue Clark properly emphasizes the Court's assertion of a virtually unlimited unilateral power of Congress (the House of Representatives and the Senate) over Native American affairs. （那个Blue Clark是何含义啊？我看起来像是他在说，国会对于部落的权利是无限的？示威？） But he fails to note the decision's more far-reaching impact:
shortly after Lone Wolf, the federal government totally abandoned negotiation and execution of formal written agreements with Indian tribes as a prerequisite for the implementation of federal Indian policy.（这里就是讲这个法律产生的效果，貌似作者是负面评价，对不对啊？）
Many commentators believe that this change had already occurred in 1871 when--following a dispute between the House and the Senate（有没有好心人告诉我这2者的关系，缺乏美国政体的知识啊） over which chamber should enjoy primacy in Indian affairs--Congress abolished the making of treaties with Native American tribes.
But in reality the federal government continued to negotiate formal tribal agreements past the turn of the century, treating these documents（这个these documents 到底指代什么啊？） not as treaties with sovereign nations requiring ratification by the Senate but simply as legislation to be passed by both houses of Congress. （黄体字是回顾下历史）The Lone Wolf decision ended this era of formal negotiation and finally did away with what had increasingly become the empty formality of obtaining tribal consent.
这个是不是讲美国和本土部落之间的恩恩怨怨的啊？我一点背景知识都没的，看的好痛苦的说。虽然做题还可以，但这仅仅是因为题目简单。
总结起来，我没看懂作者的意思。逻辑结构如下，大家帮忙评判下……
首先：在1903年，最高法庭颁布法令：不经过部落的允许，非印第安人不能在部落的领土上居住，以上这个提议被拒绝。也就是说，部落没有权利阻止美国来进去住。
接着： Blue Clark 耀武扬威说国会的权利是很大的，可以over你们部落，但是他没有关注到这个法令带来的深远影响力：即联邦政府为了实施这个法令，和部落都断交了。
接着：很多评论人说这个changes其实在1871年就发生过了，那个时候the houses和senate刚刚为了谁来管部落的事情而吵架过，1871年，Congress abolished the making of treaties with Native American tribes.这里非常看不懂，什么叫abolished the making ？ 是不是意思是说，国会撒手不管这个事情了？这里的abolish用的非常奇怪。
接着：事实上，1871年之后，联邦政府还在和部落打交道，但是用的是国会的法律条文，treating these documents not as treaties with sovereign nations requiring ratification by the Senate but simply as legislation to be passed by both houses of Congress.前面明明说已经abolish the making了，哪里来的legislation 啊？
最后 ：回到主题，
The Lone Wolf decision ended this era of formal negotiation and finally did away with what had increasingly become the empty formality of obtaining tribal consent. Lone Wolf decision一出世，结束了和部落交往的时代，也结束了已经长期形成的那种空洞的例行公事——即取得部落同意的条规。
意思是不是，以后再也不用假惺惺一定要取得部落同意了，直接可以去居住了。
大家帮忙指正下，滴汗啊…………
