Intro to English Classes is a practical overview of the main systems students need to manage in English. It begins with three basic sentence formulas: the active sentence, the question, and the passive sentence. It then explains how English tenses work through three connected skills: understanding when to use each tense, choosing the correct auxiliary, and recognizing the time markers that place a sentence in a particular tense. The final section introduces the true modal auxiliaries, such as can, might, should, and must, and explains their special rules and changing meanings.

The central idea is that English becomes easier to understand when you recognize its patterns. Sentences and questions follow formulas. Tenses depend on use, auxiliaries, and time markers. Modals have their own irregularities, but they also follow general rules.

Important points

• English sentences are organized by structure and word order.
• Questions use question words, auxiliaries, and a different placement of the subject and verb.
• The passive voice restructures an active sentence by making the object more important.
• Tenses are understood through usage, auxiliaries, and time markers.
• Modal auxiliaries have special rules and can change meaning depending on context.
• Learning these systems gives students a framework for understanding and producing English.
