有時(shí)為了強(qiáng)調(diào)或突出這種目的，也可以用in rder (nt) t d，和s as (nt) t d結(jié)構(gòu)（s as t d不可以置于句首）。

(2) 常用于“sth. + be + adj. + t d”結(jié)構(gòu)中, 這類形容詞有easy, difficult, hard, cheap, expensive, cmfrtable, gd, imprtant, impssible, dangerus等, 表示主語的特征或性質(zhì), 不定式和句子主語之間存在動(dòng)賓關(guān)系, 但常用主動(dòng)形式表示被動(dòng)意義。
