(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：本題考查句型“It's＋形容詞＋for sb to do”與“It's＋形容詞＋of sb to do”的區(qū)別。由句型結(jié)構(gòu)可知首先應(yīng)排除C、D兩項(xiàng)。for sb結(jié)構(gòu)中形容詞修飾不定式to do，其中to do是真正的主語(yǔ)，it是形式主語(yǔ)；of sb結(jié)構(gòu)中形容詞修飾sb，故選B。句意為：對(duì)他來(lái)說(shuō)彈好鋼琴很重要。
