Pourquoi est-ce si important ?<\/h2>\n\n\n\n<p>Les pr\u00e9positions de temps en anglais peuvent sembler de petits d\u00e9tails, mais elles sont essentielles pour parler de fa\u00e7on naturelle, claire et correcte.<br>Se tromper entre <strong>in, on, at<em> <\/em><\/strong>ne vous emp\u00eachera pas d\u2019\u00eatre compris, mais donnera \u00e0 votre anglais un air \u00ab scolaire \u00bb ou trop d\u00e9butant.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6.
