To say "跟我念" in English, you can say "say it with me" or "repeat after me." This phrase comes from the practice of having someone repeat something after you, typically in order to learn or memorize it. For example:

"Say it with me: the quick brown fox jumps over the lazy dog." (跟我念：“牠快速地跳过了懒狗。”)

"Repeat after me: I promise to be honest and fair." (跟我念：“我承诺要诚实公正。”)
