Podes poner:
English is very usefull to learn because besides being the global lenguage, in the future if you know English you will be able to have a better job than one that doesn't studied it at school. It's preferable to study English when you are young than when you are a grown up person because for kids is easyer to remember thing and you have much time.
Espero que esto te sirva. No se me ocurren muchas cosas. Tambien podes poner que en todos los paises lo hablan y que por ejemplo sui vas a china te van a entender muy bien si hablas ingles. si queres podes poner en la parte de que ingles es el idioma mundial que China lo sera en el futuro porqe se esta expandiendo muy rapido.
