I have probably listened to more English than anyone else in the world.
I think I have listened to the most English in the world.
世界で一番 - best in the world, number 1 in the world, most in the world
英語を聴いた - listened to english
この場合は世界の中一番の話だから”most”を入るます
Listened to the most english, heard the most English
Heard the most English in the world
Heard more English than anybody else (誰よりも私は英語を聴いた)
多分はmaybeかprobablyけれどこの場合は’I think (と思う)”は1番良いと思います。
I think I’ve
I think I have
