Itiscareless

問題詳情：

 It is careless ______ him to lose his wallet again. I think it necessary

______ him to be more careful next time.

A．of; to    B．of; for    C．for; for

【回答】

B　點撥：用固定句式法。It is ＋ 形容詞＋of/for sb. to do sth.中用of時，形容詞修飾人，説明人的品質特徵；用for時，形容詞修飾後面的事情。 careless修飾him；necessary修飾的是to be more careful next time。
