The letter in the Spanish alphabet is silent and not pronounced when speaking Spanish is H.
Ellos desean que el gobierno haga reparaciones y que nadie se lastime.
I take Spanish as well and i hate to tell you the but the correct way to say "I prefer milk" in Spanish is( prefiero la leche) u are listing the correct ways to say (She runs to maintain health) look them up if u dont believe me type in on google (Ella correr para mantener la salud in English). Hope this helps
