1)有些形容詞(包括已變?yōu)樾稳菰~的分詞)可以接不定式。
【例如】
i am eager to see him and tell him the truth. i am sure to pass the exam because i have made very good preparation.
這樣用的形容詞多是表示感情的。如：content(滿意的)，afraid(害怕的)，anxious(渴望的)，lucky(幸運的)，careful(小心的)，inclined(有意的)，willing(情愿的)，sorry(難過的)，eager(熱切的)，sure(肯定的)，determined(有決心的)，foolish(愚蠢的)，anxious(焦急的)等。這種句型有時為了突出形容詞，還可以改為以it作形式主語的句子。
【例如】
it was wise of you to accept his advice. it was stupid of her to make such a mistake. it was unwise of me to have believed him.
2)在有些形容詞后面可以跟一個that引導(dǎo)的從句。能這樣使用的形容詞如：certain(確定的)，aware (知道的)，sure (肯定的)，confident (確信的)，sorry (遺憾的)，conscious (察覺的)，afraid (擔(dān)心的)，delighted (愉快的)，surprised (驚奇的)，disappointed (失望的)等。
