专题六 非谓语动词常考点非谓语动词主要包括不定式、动名词和分词。非谓语动词一直是高考中的热点。解答非谓语动词的题目时，一定要解析句子结构，确定所设空是谓语动词还是非谓语动词，以及非谓语动词在句子中充当的功能(如状语、定语或宾补)；找准相关动词的逻辑主语，确定该动词与逻辑主语是什么关系(主动还是被动)；搜索句子中相关的时间信息，确定非谓语动词的恰当形式。非谓语功能形式动名词具有名词功能，常在句中作主语，宾语主动式doing被动式beingdone完成式havingdone/havingbeendone现在分词表主动和正在进行，常在句中作定语，状语，宾补一般式doing完成式havingdone过去分词表被动和已完成，常在句中作定语，状语，补语一般式done进行式beingdone完成式havingbeendone动词不定式表将来具体某一次，常在句中作主语，定语，状语，补语，宾语等一般式todo/tobedone进行式tobedoing完成式tohavedone/tohavebeendone
