做定语的非谓语动词的选择
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。
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 humd
and self-restraint as if i were the one ______。
a。 to correct b。 correcting
c。 having been corrected d。 being corrected
同学们只要掌握非谓语动词作定语的一般的规律，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。
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。
