Learning objectives
By the end of this lesson, you should be able to explain the rules, recognise the target forms in context, avoid common errors and apply the patterns to new sentences.
- Understand the core terms and distinctions.
- Study examples in complete sentences, not as isolated rules.
- Complete all 15 practice items before opening the answer key.
1. Past simple
Use the past simple for completed past actions, often with a definite time. Regular verbs usually take -ed; irregular verbs have individual forms. Questions and negatives use did + base verb.
2. Past continuous
Use was/were + verb-ing for an action in progress at a past time, background activity, or an action interrupted by another event.
3. Past perfect and past perfect continuous
Past perfect (had + past participle) marks an event earlier than another past reference point. Past perfect continuous (had been + -ing) emphasises duration/activity before that point.
4. Future meanings
Will + base verb can express predictions, spontaneous decisions and promises. Be going to often expresses prior plans or evidence-based predictions. Present continuous can express arranged future plans; present simple can describe schedules.
5. Future continuous and future perfect
Will be + -ing describes an activity in progress at a future time. Will have + past participle describes something completed by a future deadline. Use time clauses with when, after and before carefully: usually present forms rather than will.
