根据具体的活动类型，您还可以使用以下表达：

1. To launch a campaign
2. To sponsor a competition
3. To host a conference
4. To organize a seminar
5. To arrange a workshop
6. To schedule a webinar
7. To plan a celebration
8. To arrange a festival
9. To host a gala dinner
10. To organize a charity event
11. To schedule a sports tournament
12. To plan a product launch

总之，举办活动的英语表达有很多种，具体使用(话后面加jpg是什么梗？jpg是图片格式，jpg后缀一般在形容词后面，文字+jpg的描述形式是用文字给出一种画面感，更显生动。)哪种取决于活动的性质和目的。希望这些建议对您有所帮助！
