  Present simple is for habits, routines, and general truths. Present continuous is for things happening right now or temporary situations around the present.
• B1 Tense Review: All the Key Tenses at a Glance

  At B1 level you need to control 8 key tenses: present simple/continuous, past simple/continuous, present perfect simple/continuous, past perfect, and future forms.
• Verbs of the Senses: Look, Sound, Feel, Smell, Taste

  Look, sound, feel, smell, and taste are linking verbs — they connect the subject to a description. They are followed by adjectives, not adverbs, and are NOT normally used in continuous forms.
• Auxiliary Verbs: Do, Be, Have — How They Work

  Do, be, and have are auxiliary (helping) verbs. They are used to form questions, negatives, tenses, and for emphasis. Understanding which auxiliary to use is key to grammatical accuracy.
• Already, Still, Yet: What's the Difference?

  Already = sooner than expected (positive). Still = continuing or not yet stopped (surprise). Yet = expected but not happened (negatives and questions). Position in the sentence differs for each.
