这类考题的考查方式有两种，一是四个选项中有两个相对的选项to do something 和 to doing something，这时考查的自然是to的性质；另一种是to在题干中，如③。uyh中国英语学习网
8) 分词前连词的使用uyh中国英语学习网
分词前连词的使用是为了使分词的作用更加明了，使考生更加准确地理解试题。考查有两种情况uyh中国英语学习网
(1)根据连词选择适当的分词形式uyh中国英语学习网
Michael used to look hurt and surprised when ______.(1995.1)uyh中国英语学习网
A. scolding B. to scold C. having scolded D. scolded uyh中国英语学习网
when的使用说明非谓语动词做时间状语，答案不可能是B，从scold与句子主语间的逻辑关系来看，应该是动宾关系，答案应该是D。uyh中国英语学习网
(2)根据状语的功能选择不同的连词uyh中国英语学习网
Careful surveys have indicated that as many as 50 percent ofuyh中国英语学习网
patient do not take drugs ___ directed.(1996.1)uyh中国英语学习网
A. like B. so C. which D. asuyh中国英语学习网
由上下文的意思可以看出，分词所做的是方式状语，连词应该是as。uyh中国英语学习网
9) 非谓语动词的体

非谓语动词中分词的体有完成体和进行体，即having done, having been done和being done，完成体只用于做状语的场合，而进行体可以用于做定语和做补足语。uyh中国英语学习网
动名词的体也有having done, having been done和 being done的结构主要用于做主语和宾语的场合。uyh中国英语学习网
不定式的体有to be doing 和to have done，主要用于pretend, happen, seem, appear, be said to等结构中。如：uyh中国英语学习网
① The man in the corner confessed to _____ a lie to the manageruyh中国英语学习网
of the company.(1997.6)uyh中国英语学习网
A. have told B. be told C. being told D. having tolduyh中国英语学习网
having told在句中做介词宾语，表示动作发生在谓语动词之前。uyh中国英语学习网
② I'd rather read than watch television; the programs seem ____ uyh中国英语学习网
all the time.(1997.1)uyh中国英语学习网
A. to get worse B. to be getting worseuyh中国英语学习网
C. to have got worse D. getting worseuyh中国英语学习网
从all the time的使用可以推断get worse是一个渐变过程，所以用不定式的进行体。uyh中国英语学习网
③ The speech _____ a lively discussion started.(1995.1)uyh中国英语学习网
A. being delivered B. was delivereduyh中国英语学习网
C. be delivered D. having been delivereduyh中国英语学习网
该结构属于独立主格结构做时间状语，状语分词所表示的动作发生在谓语动词之前，所以应该用完成体，答案为D。
