动词不定式在句中起着名词、形容词和副词的作用,可以担任除谓语以外的其它成份。高考侧重考查其作宾语、定语、目的状语、表语的功能以及不带to的用法。
一、不定式的宾语功能 hope, wish, expect, pretend, plan, decide, seem等动词后需接不定式作宾语。
例:She pretended ______ me when I passed by.(MET’89) to see B. not seeing C. to not see D. having not seen 解析:pretend后应接不定式作宾语,其否定式是“not to do”,故选A。
二、不定式的定语功能 不定式作定语,被其修饰的名词为不定式所表动作的逻辑主语、逻辑宾语等。
例1:There are five pairs ______, but I’m at a loss which to buy. (上海1999) A. to be chosen B. to choose from C. to choose D. for choosing 解析:从语境可知,该空作定语修饰five pairs,且five pairs为该空所表动作的逻辑宾语,所以应填不定式to choose from作定语,表示“从……中挑选”,故选B。
例2:It seems that he has no pen ______. (北京 2003 春) A. to write B. to write with C. writing D. writing with 解析:从语境可知该空作定语修饰pen,故选B。
三、不定式的目的状语功能 不定式常作目的状语,同时它可用于一些固定搭配来作目的状语,如 in order (not ) to do,so as (not) to do。
例1:-Mum, why do you always make me eat an egg every day? -______ enough protein and nutrition as you are growing up. (上海1999) A. Get B. Getting C. To get D. To be getting 解析:从语境可知,每天吃一只鸡蛋的目的是给你提供更多的蛋白质和营养,所以应用不定式作目的状语,故选C。
例2:In order to gain a bigger share in the international market, many state-run companies are striving ______ their products more competitive. (上海 2002) A. to make B. making C. to have make
