Question

这道题为什么选A

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. A. the largest share for any country to contribute B. the largest share that any country has contributed C. which makes it the largest share for any country to contribute D. having the largest share to be contributed by any country E. having the largest share to have been contributed by any countrythe answer is b, it is ok, 但想问一下a为什么不好，记得语法书上好象说过最高级修饰名词，后面一般要跟不定式，象the first sth to do sth, 即使没有这一条，也想知道这里a为什么不对？ 只是因为后面有时间状语吗？

Answer 1

因为后面有since呀，觉得前面要选一个有have done，况且to do 表将来目的，没有体现这个意思吧，前面那个是已经发生的，不是要去干什么的

Answer 2

A选项 For X to do Y 带有很强的目的性，而这里share应该不是说用来做什么，而是要来凸显这个share很大， 所以语义上也应该是B。 一点愚见~
