(1)一交换。
不定式、动名词作表语是名词性表语,说明主语是什么。检验是否是名词性表语的办法,是将主语和表语交换位置,句意仍不变。如: Her wish is to become an engineer.=To become an engineer is her wish.
(2)二对应。
即:动名词作主语+系动词+动名词作表语
不定式作主语+谓语+不定式作表语
如:Teaching is learning.
(3)三表状态和特性。
分词作表语表示主语所处的状态或特性。如:
The report was so inspiring that they were all excited.(inspiring说明主语report所具有的特性,excited则说明主语they所处的状态。)
