问题补充：

The rich man gave away 5 his money to charity to help the poor children in Africa.

A. millions

B. million

C. millions of

D. million of

答案：

A. millions

B. million

C. millions of

(答案→)D. million of

解析：本题中极易误选B，对于确定所指时million后不加s,不加of.但本题中of 与后面的his money构成所属关系，跟前面没有直接的联系，句意：这个富人将他的5百万元捐给了慈善机构来帮助非洲的贫困孩子。故选C.
