先看几个例句，判断不定式在句中的成分。 1．To learn a foreign language is difficult . 2． His wish is to be a driver . 3．Tom wanted to have a cup of beer . 4．The teacher told us to do morning exercises . 5．I have nothing to say . 6．They went to see their aunt . 7．It’s easy to see their aunt. 8．I don’t know what to do next . 9．I heard them make a noise .
掌握动词不定式应注意的几个问题：
1． “to” 是不定式符号还是介词，下列短语中的to 都是介词。 agree to object to close to , come to , lead to , refer to , equal to , familiar to , point to , thank to , devote to , next to , belong to , be used to , look forward to
2． 带to 还是不带to I have no choice but to give in I cannot do anything but give in I saw him enter the classroom . （ 但是： He was seen to enter the classroom .）
3． 动词不定式逻辑主语是由for 作为标记的。但是有时用of . It’s necessary for you to study hard . It’s foolish of him to do it . 与of 连用的形容词有： good, kind , nice , wise ,clever , foolish , right , wrong , careful , careless , polite , possible
4．后接不定式作宾语的动词有： want , hope , wish , like , begin , try , need , forget , agree , know , promise , teach , refuse , help , arrange , dare , decide , determine , fail , manage , offer , prepare , continue , ask , mean , choose , expect etc. 需要宾语补足语的动词不能用动词不定式直接做介词的宾语，而要用it做形式宾语。例如：通常不说We think to obey the laws is important . 而说We think it important to obey the laws .
