1.“Those fortunate to achieve great wealth should put it to work for the good of humanity,"Allen wrote several years ago.
这里的fortunate是什么词性?to do的成分?
2.Such realities do little restore the luster of the American "brand" or the appeal of US democracy as a "shining city on a hill,"to quote Ronald Reagan.
这里的to do做什么成分
1) "Those fortunate to achieve great wealth should put it to work for the good of humanity," Allen wrote several years ago.
解答:
Those fortunate to achieve great weath=Those who are fortunate to achieve great wealth
2) to quote Ronald Reagan.
表示引用谁说的话时,我们常用
a. someone is/was quoted as saying ...
b. to quote someone
其中b的形式通常是局部的引用,而a通常是整句以上的引用
至于这种结构你是给它分类为什么独立成分,补语,插入语...随便,你爱叫它啥就啥,我从来不纠缠这些模棱两可的成分叫法
