Question

(天津市2006)

It's important ________ the piano well.

[　　]

A．of him to play

B．for him to play

C．of him playing

D．for him playing

Answer 1

答案：B
解析：

解析：本题考查句型“It's＋形容词＋for sb to do”与“It's＋形容词＋of sb to do”的区别。由句型结构可知首先应排除C、D两项。for sb结构中形容词修饰不定式to do，其中to do是真正的主语，it是形式主语；of sb结构中形容词修饰sb，故选B。句意为：对他来说弹好钢琴很重要。
