perfect participle(现在分词的完成式)
（1）____ his telephone number, she had some difficulty getting in touch with Bill. A. Not knowing B. Knowing not C. No having known D. Having not known(上海高考,91)
(2) ____ a reply, he decided to write again. A. Not receiving B. Receiving not C. Not having received D. Having not received (全国高考,92-39)
试题(1)的答案为A,能否选C呢?试题(2)的答案为C,能否选A呢?
做这样的试题,要懂得现在分词的一般式和完成式的特点。前者表示其动作与谓语的动作同时发生,而后者则表示其动作先于谓语的动作。在试题(1)中,Not knowing 与 had 具有同时性,而在试题(2)中,Not having received 所表达的动作先于 he decided 所表达的动作,故只能选 C,而不能选 A。请对比:
