to do 作表语学案(选必三U1Art)
教学重点 · 结构：主语 + 系动词（be/seem/appear 等）+to do sth.，表主语内容、目的、将来动作；· to 的省略：主语含实义动词 do 时，表语不定式可省 to；· 被动式：to be done，表被动含义；· 固定句型：be to do（计划 / 注定）、seem/appear to do、be likely to do；· 区分 to do 和 V-ing 作表语：to do 表具体 / 一次性 / 未发生，V-ing 表抽象 / 习惯性；遵循主语对称原则。
教学难点 · 精准判断 to 的省略场景；· 语境中区分 to do 与 V-ing 作表语；· 灵活运用 to do 的被动式；· 系动词后 to do 与分词的综合辨析。
一、核心概念
动词不定式（to do）作表语，放在系动词之后，用来说明主语的具体内容、目的、性质、将来动作。
常见系动词：be(am/is/are/was/were)、seem、appear、remain、prove、turn out等。
基本结构：主语 + 系动词 + to do sth.
二、基本用法
1. 说明主语的具体内容
主语通常为抽象名词：wish, hope, idea, plan, task, duty, job, purpose, goal, aim等。
例：My plan is to travel abroad this summer.
2. 表示目的/意图
例：The only thing you can do is wait.
3. 表示将来、安排、注定
例：The meeting is to be held tomorrow.
三、重要注意事项
1. 不定式符号 to 的省略
当主语部分含有实义动词do（do/does/did/done）时，作表语的不定式可省略to。
例：What I want to do is (to) have a good rest.
2. 固定句型
be to do sth. 按计划/安排将要做；注定
seem/appear to do 似乎……
be likely to do 很可能……
to do被动式为to be done
The report is to be handed in before Friday. 这份报告需要在周五之前交上来。
四、区分to do和V-ing作表语
to do 表语：强调具体、一次性或尚未发生的动作，带有未来或目的的含义。
doing 表语：强调抽象、习惯性的状态或经常性的行为。
1. 具体 vs 抽象
当描述一件具体的事情时用 to do，泛指某种概念或状态时用 doing。
· His dream is to become a pilot.（他的梦想是成为一名飞行员。）——指具体的梦想目标，尚未实现。
· His job is flying planes.（他的工作是开飞机。）——指职业内容的抽象概括，强调经常性的状态。
2. 一次性 vs 习惯性
强调某一次的动作建议用 to do；强调反复发生的习惯用 doing。
· What I suggested was to go there by bike.（我建议的是骑自行车去那里。）——针对那一次的具体建议。
· What I hate most is getting up early.（我最讨厌的是早起。）——表达一贯的厌恶情绪。
3. 主语对称原则
如果主语是 doing（动名词），表语也倾向于用 doing 保持平衡；主语是 to do（不定式），表语也倾向于用 to do。
· Seeing is believing./To see is to believe.（眼见为实。）
