Itiscareless

问题详情：

 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　点拨：用固定句式法。It is ＋ 形容词＋of/for sb. to do sth.中用of时，形容词修饰人，说明人的品质特征；用for时，形容词修饰后面的事情。 careless修饰him；necessary修饰的是to be more careful next time。
