大学英语语法之形容词+不定式/that从句
1)有些形容词(包括已变为形容词的分词)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.
这样用的形容词多是表示感情的。如：content(满意的)，afraid(害怕的)，anxious(渴望的)，lucky(幸运的)，careful(小心的)，inclined(有意的)，willing(情愿的)，sorry(难过的)，eager(热切的)，sure(肯定的)，determined(有决心的)，foolish(愚蠢的)，anxious(焦急的)等。这种句型有时为了突出形容词，还可以改为以it作形式主语的句子。
【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)在有些形容词后面可以跟一个that引导的从句。能这样使用的形容词如：certain(确定的)，aware (知道的)，sure (肯定的)，confident (确信的)，sorry (遗憾的)，conscious (察觉的)，afraid (担心的)，delighted (愉快的)，surprised (惊奇的)，disappointed (失望的)等。
【例如】
i am aware that i must begin now if i want to pass the test.they were disappointed that you didn’t show up at yesterday’s party. i am sorry that the chinese soccer team was defeated again.
