- *She plans to study abroad next year.*to+原形动词study
- *They plan on visiting the museum this weekend.*on+动名词visiting
二、语义侧重与语气强度
plan to do “明确的意图”和“确定的目标”,语气更正式、坚定;plan on doing “基于现有情况的计划”,常隐含“预期”或“可能性”,语气更口语化,不确定性稍强。
- *The company plans to launch a new product in Q3.*“launch”是明确的目标,语气坚定
- *We plan on finishing the project by Friday, but it depends on the budget.*“finishing”是基于当下预期的计划,但带有条件限制,不确定性更明显
三、场景应用与语境限制
plan to do 多见于正式语境如书面报告、商务沟通,或表达长期、固定的计划;plan on doing 更常用于口语,或搭配时间、条件等状语,描述短期、灵活的安排。
- 正式场景:*The government plans to reduce carbon emissions by 20% in five years.*政策文件中的长期计划
- 口语场景:*I plan on going to the gym after work—want to join me?*日常对话中的临时安排,可灵活调整
四、否定形式的细微差别
否定时,plan to do 通常在“plan”后加“not”:*He does not plan to attend the meeting.*
plan on doing 则多在“on”后加“not”:*They plan on not staying late tonight.*虽不常见,但语法上更介词短语的否定逻辑
综上,两者虽均表示“计划做某事”,但在语法结构、语义侧重和场景应用上存在显著差异:plan to do 重“确定意图”,正式且坚定;plan on doing 重“灵活预期”,口语化且带不确定性,需根据语境选择使用。

这是两者最直观的语法区别。例如:
