conocerlas en fundamental para poder hablar con fluidez y correctamente. En el aprendizaje del idioma entran en juego muchas cosas, entre ellas, conocer la gram\u00e1tica y saber utilizarla.<\/p>\n\n\n\n<p>Es por ello que el uso de &#8220;a&#8221; y &#8220;an&#8221; en ingl\u00e9s se hace tan importante. \u00bfNo te chirr\u00eda a ti cuando oyes &#8220;tengo un casa bonita&#8221;? Pues en ingl\u00e9s pasa lo mismo, no es correcto decir: <br>\u274c\u274cI live in <strong>an<\/strong> beautiful house. (La oraci\u00f3n corregida ser\u00eda: I live in <strong>a<\/strong> beautiful house)<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Comprensi\u00f3n de lectura y escritura&nbsp;<\/h3>\n\n\n\n<p>A la hora de comprender un texto es cierto que puede no ser tan relevante el uso de &#8220;a&#8221; y &#8220;an&#8221; como el mal uso de un verbo, o de un sustantivo. Al fin y al cabo, nosotros tenemos la capacidad de comprender que el usar &#8220;a&#8221; o &#8220;an&#8221;, el escrito est\u00e1 refiri\u00e9ndose a algo indefinido.<\/p>\n\n\n\n<p>Sin embargo, a la hora de escribir es fundamental saber utilizar los m\u00faltiples art\u00edculos indefinidos ya que son una falta gramatical realmente importante en el idioma ingl\u00e9s.
