Hi Omar, You've actually asked three questions, and there are many errors. Jesús has given some corrections, so here are the correct sentences that you need: "What's the difference between them?" "What's the difference between ____ and ____?" "What do they mean?" "What is the difference between the following sentences?" For "she has gone" and "she is gone", the first means she recently left, and the second means her current status. We would simply say "she's gone" and not worry about analysing the grammar too much. We know the meaning from the context. It's not a difference of dying or physically moving away. We use verbs like "go" and "depart" to indirectly mean "die". "She's gone" can mean either, and we know this from the context. The phrase alone doesn't tell us. I agree that "She has passed away" is probably the phrase you need. I've only heard "s/he's gone" when the person died a few moments ago, and only after suffering serious injury or disease (ie. we already knew that the person's death would be a possibility).

Hola Omar, Voy a corregir los errores que cometiste en tu pregunta. Para empezar, es 'difference' y no 'differents'. También es 'between' y no 'betwwen'. 1.) Sería muy raro usar esta expresión para decir que alguien se murió. Es más común decir 'She has passed away' 2.) Vas a usar 'one' cuando tu refieres a algo en especifico. Por ejemplo, si hay UNA sola silla en la cocina, dirás 'There is ONE chair in the table.' La a se refiera a cualquier cosa. Como 'Hay un avión en el cielo' sería 'There is an airplane in the sky.' Acuérdate con el inglés tienes que ver si una palabra necesita 'an' o 'a'. 3.) Sí sería correcto usar 'course' si estás haciendo un curso de inglés aunque si es una clase es más común decir 'class'. Espero que esto te ayude y si tienes más preguntas, me dejas saber. Saludos y suerte con el inglés!
