解法： 判断选项与【主句主语】的关系。
| 动作状态 | 主语发出动作 (主动) | 主语承受动作 (被动) |
|---|---|---|
| 一般 / 进行 | doing | - |
| 动作先发生 (完成) | having done | done / having been done |
| 目的 ("为了...") | to do | |
解法： 判断选项与【空前名词】的关系。
doing (正在进行/经常) done (已完成) being done (正在被做) to be done (将来被做)
核心口诀： 人 ed，物 ing (例：I am excited / The trip is exciting)
区分： doing 侧重经常性、习惯性动作；to do 侧重一次性、具体的动作。 多选 doing 作主语。
