A March 2000 Census Bureau survey showed that Mexico accounted for more than a quarter of all foreign-born residents of the United States, the largest share for any country to contribute since 1890, when about 30 percent of the country's foreign-born population was from Germany.

which makes it the largest share for any country to contribute
having the largest share to be contributed by any country
having the largest share to have been contributed by any country
题目分析:
本题的划线部分是a quarter of all foreign-born residents of the United States的同位语或定语。
选项分析:
选项A:for any country to contribute是不定式的复合结构。需要将这个不定式的复合结构改为定语从句,这点考查了不定式和从句的区别。用之于本题,主句讲的是:
墨西哥占据了超过四分之一的在外国出生的美国居民。
在这个主句发生时,同位语the largest share for any country to contribute since 1890不会产生任何状态的变化。即,contribute事件是去解释超过四分之一这个数据的,不会因主句的发生与否而存在或消失(墨西哥人占据还是不占据四分之一,这个四分之一都是自从1890年以来最大的百分比)。
选项B:Correct. 本选项在语法和逻辑上均是正确的。
选项C:本选项是a quarter of all foreign-born residents of the United States的非限制性定语从句,将先行词放入从句中,则有:
a quarter of all foreign-born residents of the United States makes it the largest share for any country to contribute since 1890.
在逻辑上,四分之一这个百分比不能发出“使得任何国家的贡献变为最大的占比”这个动作。只能是,四分之一本身“是”最大的占比。
选项D:不定式短语to be contributed错误同选项(A)。
选项E:不定式短语to have been contributed错误同选项(A)。
the largest share 做同位语;DE 墨西哥无法发出HAVE这一动作
