问题补充：

It the children two hours the book.

A. take; to

B. takes; reading

C. takes; to read

D. takes; on

答案：

A. take; to

B. takes; reading

(答案→)C. takes; to read

D. takes; on

解析：：take 用于 it takes sb ... to do sth句型，仅指花费时间（three hours等），必须用it作形式主语。句意：读这本书，花了这个孩子两个月的时间。结合语境可知本句描述的是客观性动作，句子主语it是为单数第三人称，故谓语动词用单数，选C。
