作定语,故选C。
2. 如果句子的主语是动词不定式所表示动作的施动者,则大都采用动词不定式的主动形式来作名词的后置修饰语。如:
I have a letter to write. (不用to be written)
我有一封信要写。
You need something to eat. (不用to be eaten)
你需要吃些东西。
但是,在there be 结构中,虽然常用主动语态,但是用被动语态也可以。如:
There is a meeting to attend. (可用to be attended)
要参加个会议。
3. 当征求对方是否有事需说话人做时,不定式作定语用被动语态。如:
"Would you have a letter to be typed, manager?" asked his secretary. "经理,你有信要打吗?"秘书问道。
二、动词-ing形式的被动语态
当动词-ing 形式的逻辑主语是动作的承受者时,就要用动词-ing 形式的被动语态。
1. 动词-ing形式的被动语态和它的主动语态一样,在句中可以作主语和宾语。如:
He was afraid of being scolded by the teacher.
他害怕被老师责骂。(宾语)
再如下面的高考题:
______ to sunlight for too much time will do harm to one's skin.
A. Exposed B. Having exposed
C. Being exposed D. After being exposed
分析:本句中expose与one's skin是动宾关系,根据句意,应该是皮肤被暴露在阳光下,所以要用动词-ing形式的被动形式作主语,故答案为C。
2. 一些动词如need, want, require等作"需要"讲时,其后的动词-ing形式
的主动语态表示被动意义,也可以用不定式的被动形式来替换。如:
