名师点拨：英语四级考试谓语动词语法精解

　　从近几年的考查情况来看，对做定语的非谓语动词的考查有两种情况：

　　(1)对一般概念的考查，而不是固定结构中的非谓语动词做定语。如：

　　① The project ____ by the end of 2000, will expand the city's

　　telephone network to cover 1,000,000 users.(1999.6)

　　A. accomplished B. being accomplished

　　C. to be accomplished D. having been accomplished

　　② If I correct someone, I will do it with so much good humor

　　and self-restraint as if I were the one ______.(1996.6)

　　A. to correct B. correcting

　　C. having been corrected D. being corrected

　　同学们只要掌握非谓语动词做定语的一般的规律,就可以判断①题答案为C，②题答案为D。

　　(2)对固定结构的考查，如：

　　① The professor could hardly find sufficient grounds _____ his

　　arguments in favor of the new theory.(2000.6)

　　A. to be based on B. to base on

　　C. which to base on D. on which to base

　　② The pressure _____ causes Americans to be energetic, but it

　　also puts them under a constant emotional strain.

　　A. to compete B. competing

　　C. to be competed D. having competed

　　①题为不定式做定语的固定形式，答案为D，②题为某些特定名词的定语结构，答案为A。在英语中有些名词，如动词变来的名词，形容词变来的名词，以及means,way, time, moment, reason等要求其后用不定式做定语，不定式没有体的变化。
