③序数词形容词最高级或被only, last, next等修饰的名词可以用不定式作定语:
She was the only person to survive after the earthquake.
Tips: 不定式在作定语时,有时与被修饰的名词有意义上的主谓关系、同位关系、动宾关系,如果该不定式是不及物动词,它后面需要加上适当介词。
Eg. Hes always the first to come and the last to leave. 主谓关系
Ive no time to listen to your excuse. 同位关系
She has a meeting to attend. (动宾关系=attend a meeting)
Theres nothing to worry about. (动宾关系=worry about nothing)
6. 作状语
不定式可以作状语,表示目的、结果、原因、条件等。
①to, in order to , so as to (不能放在句首)作目的状语
2005年辽宁卷22题:All these gifts must be mailed immediately _____ in time for Christmas.
A. in order to have received B. in order to receive C. so as to be received D. so as to be receiving
②在soas to, such.as to, only to 结构中不定式作结果状语,其中only to用于表示意想不到的结果。
He hurried to the station only to find the train had gone.
③enough to, tooto结构
