英语语法~
But no matter how tough things are right now,we still give thanks for that most American of blessings,the chance to determine our own destiny.
the chance to determine our own destiny是什么?状语?

答：这是一个很好的问题,但主要问题还在于for that most American of blessings,
为什么不是give thanks to...? 这里的American是名词还是形容词,如是名词,为什么不是most Americans? 如是形容词,为什么后面还跟一个of短语?
确实,这是奥巴马11月24日感恩节电视讲话,我看了录相（有字幕）,听了录音,看了对应稿.但对这一点仍存疑问：这字幕是原来就有的吗?这是听力稿吗?我听的时候这个blessings感觉这个[e]的发音走样了.这前面有这个of吗?
从语境来看,这里的give thanks for sth. 相当于我们常说的：thank you for your apples 之类的.
所以这个for后面的是名词词组.中心词是blessings, the chance+定语是它的同位语.
这是别人的翻译：
I know that for many of you, this Thanksgiving is more difficult than most. But no matter how tough things are right now, we still give thanks for that most American of blessings, the chance to determine our own destiny. The problem we face didn't develop overnight, and we won't solve them overnight. But we will solve them. All it takes is for each of us to do our part. With all the partisanship and gridlock here in Washington, it's easy to wonder if such unity is really possible. But think about what's happening at this very moment: Americans from all walks of life and coming together as one people, grateful for the blessings of family, community, and country.
大家都知道,今年的感恩节比以往都艰难.但无论现在事情有多么艰难,我们仍然要感谢这个大多数美国人所希望的、决定我们自己命运的机会.我们所面临的问题不是一夜之间形成的,也不会在一夜之间解决.但它们最终会被解决.我们现在要做的就是做好每个人分内的事.随着在华盛顿的党派对立问题和政治僵局的出现,我们很容易会怀疑团结是否真的还有可能?但是想想此刻正在发生的事：各行各业的人作为同一个民族团聚在一起,感恩家庭、社会和国家的庇佑.
我感觉原文中没有这个of,上面的翻译也有问题.
能说得通的是：But no matter how tough things are right now, we still give thanks for that most American blessings, the chance to determine our own destiny.
译：但无论现在事情有多么艰难,我们仍然要感谢这个最具美国特色的祝福,这个决定我们自己命运的机会.
搜索网络,我发现一个我以前没有注意到的语言现象,好就：that most American of +名词
表示：那个最美国化的.,可能是美国英语,还确实象Chinglish,看Obama的嘴形,这个of尽管很轻,还真是有的!
1. The West has long held pride of place in motion pictures, both as a production center and as the inspiration for that most American of film genres.
2. ‘Tis the season for that most American of summertime activities: the end-of-the-season, last-fling-before-school-starts road trip!
3. Asher & Company showed their love, loyalty, and patriotism for that most American of sports—baseball—with a stadium lunch.
我又搜索了一下,找到了很多that most 国家形容词 of +名词的情况.看来应该有这样的英语惯用法.长见识了!
