“It is +adj.+ to do sth.”句型中,it在句中作形式主語,而真正的主語是后面的不定式形式。有時動詞不定式有自己的邏輯主語,常由“for”或“of+sb.”構(gòu)成。it 作形式主語時常用兩種句式結(jié)構(gòu): (1)It is +adj. +for sb. +to do sth. 形容詞描述事物的特征、性質(zhì),如:easy,difficult,interesting,funny,dangerous,important,impossible,useful等 (2)It is +adj. +of sb.+to do sth. 形容詞描述行為者的性格、品質(zhì),如:kind, friendly,nice,right,clever,polite,careless,cute等 例如: It's interesting for us to play games here in the park,but I think it's impolite of us to make so much noise. 我們在公園里玩游戲很有意思,但我覺得我們這么吵鬧是不禮貌的。 Let's have a try. 謝謝! |
