Q24:

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 country

看了讨论，此题似乎没有定论

答案是B

又翻出来讨论真是不好意思，有劳大家了

C、D、E肯定不对。A和B相比，B更清晰些。

illgetthere

谢谢crbeijing,B中的has contributed与前面的时态能对应吗？
