一、 非谓语动词
　　近几年的语法测试中非谓语动词约占31。1%，平均每年近5道题，可谓是语法项目考查的重点，那么非谓语动词的考查都有哪些特点，解答时又应注意些什么呢?下面我和大家就一起来分析一下：

　　1、非谓语动词考查特点

　　1) 谓语动词与非谓语动词的判断

　　对谓语动词与非谓语动词区别的考查主要集中在独立主格结构，如：

　　all things ___ because of the snowstorm， many passengers could do nothing but take the train。(1999。1)

　　a。 had been canceled b。 have been canceled

　　c。 were canceled d。 having been canceled

　　四个选项中有三个是谓语动词，只有d是非谓语动词，只要同学们能判断出这里是非谓语动词做状语，则不用考虑时态的问题，答案自明。

　　2) 谓语动词后不定式与动名词的选择

　　谓语动词后接不定式还是接动名词也是四级语法测试中的一个题眼。如：

　　① i don‘t mind ____ the decision as long as it is not too late。(2000。1)

　　a。 you to delay making b。 your delaying making

　　c。 your delaying to make d。 you delay to make

　　② had i remembered ____ the windows， the thief would not have

　　got in。(1996。1)

　　a。 to close b。 closing

　　c。 to have closed d。 having closed

　　③ your hair wants ______ 。 you‘d better have it done tomorrow。

　　a。 cut b。 to cut c。 cutting d。 being cut(1997。6)

　　这类题涉及三个方面：

　　谓语动词后应该接不定式还是动名词?

　　即可接不定式又可接动名词时，结构和意思上有何差别?

　　不定式与动名词用主动形式还是用被动形式?

　　3) 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。(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
