你可以说 "I want to perform" 来表达你想去表演的意思。

"Perform" 是一个动词,意思是表演、展示或执行,例如:

I want to perform a song at the school talent show. (我想在学校的才艺表演中唱一首歌。)
She performs magic tricks at children's birthday parties. (她在儿童生日派对上表演魔术。)

"Perform" 来自拉丁语 "performare",意思是完成或履行。在英语中,它最初用来描述戏剧、音乐、舞蹈或其他艺术形式的表演,但现在也可以用来描述其他各种活动,例如:

The band is performing at the music festival this weekend. (乐队本周末将在音乐节上演出。)
He performs stand-up comedy at local clubs. (他在当地俱乐部表演单口喜剧。)
