【摘要】：2013六级考试进入了最后的冲刺阶段，以下是威廉希尔app 特为考生们整理了2013英语六级语法关于非谓语动词。预祝考生们通过考试!
在英语中，不是用于句子谓语而是用于担任其他语法功能的动词叫做非谓语动词，也称作动词的非限定形式。
非谓语动词有三种形式：不定式(the Infinitive)、分词(the Participle)和动名词(the Gerund)。
不定式
1. 构成与形式
不定式由不定式符号“to + 动词原形”构成(有时不带to)。前面可以加某些疑问代词，如what, who, which, 或疑问副词，如when, where, why等，构成特殊的不定式短语，如what to do next, how to get there等。
不定式形式有：
主动形式
被动形式
一般式
to do
to be done
完成式
to have done
to have been done
进行式
to be doing
to be being done
完成进行式
to have been doing
2. 用法
不定式不能单独作谓语，没有人称和数的变化，具有名词、形容词和副词的特征，而且还保留着动词的特征，因而可以有状语修饰，如果是及物动词，还可以带宾语，从而构成不定式短语。不定式或不定式短语在句子中可以作主语、表语、宾语、定语、状语、主语补足语和宾语补足语。
