一、辨析:it is + adj +for sb 和it is + adj + of sb.
①“It’s +adj. + of + sb.+不定式”表示“某人(做某事)怎么样” 一般用表示人物的性格,品德.表示主观感情或态度的形容词.若形容词是描述逻辑主语(行为者) 的性格、品质特征的形容词. 这个 adj.是用来形容 sb.的.
这类形容词有: good( 好的),kind( 友善的),nice( 友好的),polite( 有礼貌的),clever(聪明的),foolish(愚蠢的),lazy(懒惰的), careful(细心的),careless(粗心的 ),right( 正确的 ),wrong( 错误的 )bad( 坏的 ),brave( 勇敢的 ),cruel( 残忍
的),honest(诚实的),naughty(顽皮的),wise(聪明点),rude(粗鲁的)等.用 of sb.例如:
It’s very kind of you to help me.(=You are very kind to help me.)
你能帮助我,真好.
It’s very rude of her to say such words.
(=She is very rude to say such words.)她说这样的话,真粗鲁. It’s foolish of him to go alone.(=He is foolish to go alone.)

It's very nice of you to help me. 你来帮助我,你真是太好了.
It's very kind of you to look after my cat.
②“It’s + adj. + for + sb.+不定式”表示“做某事对某人来说怎么样”.常用于表示事物的特征特点,表示客观形式的形容词.若形容词仅仅是描述事物,不是对不定式行为者的品格进行评价,用 for sb.这类形容词有:
important( 重 要 的 ),necessary( 必要的 ),difficult( 困 难 的 ),easy( 容易的),hard(艰难的),dangerous(危险的),safe(安全的),useful(有益的),pleasant(舒适的),interesting(有趣的),impossible(不可能的), right(正确的) likely(可能的) 等.用 for sb,例如:
