问题补充：

Football is so exciting thatpeople in the world play it.

A. million of

B. two millions of

C. millions of

Dtwo million

答案：

A. million of

B. two millions of

(答案→)C. millions of

D. two million

解析：句意：足球是如此的令人兴奋以至于世界上数以百万计的人都在踢足球。数以百万计的表达是million后加s再加介词of，而million前面如果有数词修饰，则在后面直接跟名词的复数形式，A和B项形式都是错误的，虽然D的结构正确，但是体现不出来就恰好是两百万人在踢足球；故选C。
