Welcome to Tenses and Time Reference!

In the IB Diploma Programme (DP) Language B course, grammar isn't just about following rules—it's a tool to help you communicate clearly and effectively. Mastering tenses and time reference is essential for scoring high in Criterion A (Language) for your Writing (Paper 1) and your Individual Oral. It helps you tell stories about your Experiences, describe your Identities, and discuss global issues in Sharing the Planet.

Don't worry if tenses feel confusing at first. We will break them down into simple pieces so you can use them with confidence!

1. The Present: Right Now and All the Time

In English, we use different present tenses depending on whether something is a permanent fact or a temporary action.

Present Simple

Use this for facts, habits, and routines. In your IB themes, this is perfect for describing Social Organization (how societies work) or Identities (who you are).

Formula: \( Subject + Verb (s/es) \)

Example: "Many students study global issues in school."
Example: "The sun rises in the east."

Present Continuous

Use this for actions happening right now or temporary situations.

Formula: \( Subject + am/is/are + Verb-ing \)

Example: "I am writing a blog post about environmental ethics."
Example: "Technology is changing the way we communicate." (A trend happening now).

Quick Tip: Use the Present Simple for things that are generally true and the Present Continuous for things that are changing or happening at this moment.

2. The Past: Sharing Our Stories

The "Experiences" theme requires you to narrate events. To do this well, you need to navigate different points in the past.

Past Simple

Use this for completed actions at a specific time in the past.

Example: "Last year, my family traveled to Japan for a holiday."

Past Continuous

Use this to describe the "background" of a story or an action that was interrupted.

Example: "I was walking to school when I saw the protest for human rights."

Past Perfect: The "Past of the Past"

This is a high-level structure that shows variety in your writing. Use it when you are talking about two things in the past and want to show which one happened first.

Formula: \( Subject + had + Past Participle \)

Example: "By the time the teacher arrived, the students had already finished the experiment." (The finishing happened before the arrival).

Key Takeaway: Use the Past Simple for the main events and the Past Continuous for the atmosphere or background.

3. The Present Perfect: Connecting Past and Present

This is one of the most important tenses in English B because it connects what has happened to the present situation.

Present Perfect Simple

Use this for experiences when the specific time doesn't matter, or for actions that started in the past and continue now.

Formula: \( Subject + have/has + Past Participle \)

Example: "I has lived in this city for ten years." (I still live here).
Example: "Scientists have discovered new ways to use solar energy." (We don't know exactly when, but the result is important now).

Did you know? If you say "I lost my keys" (Past Simple), you might have found them by now. If you say "I have lost my keys" (Present Perfect), it implies you still don't have them!

4. Looking Forward: The Future

When discussing Human Ingenuity or Sharing the Planet, you will often need to predict or plan for the future.

Will vs. Going To

  • Will: Used for spontaneous decisions, promises, or general predictions.
    Example: "I think robots will do most of our chores in the future."
  • Going To: Used for intentions and plans already made.
    Example: "Our school is going to start a recycling program next month."

Present Continuous for the Future

Use this for fixed arrangements with other people (like an appointment or a scheduled event).

Example: "I am meeting my teacher tomorrow to discuss my HL literary work."

5. Common Mistakes to Avoid

Even advanced students can make small errors that affect their Criterion A score. Watch out for these:

  • The "s" in third person: In Present Simple, don't forget the "s"! (He speaks, not He speak).
  • Tense Jumping: If you start a story in the past, stay in the past. Don't switch to the present halfway through unless there is a clear reason.
  • Since vs. For: Use since for a specific point in time (since 2010) and for for a duration (for five years). Both are used with the Present Perfect.

6. Summary Table for Quick Review

Time Reference: General Truths / Habits
Tense: Present Simple
Example: "I exercise every morning."

Time Reference: Action in progress now
Tense: Present Continuous
Example: "I am exercising right now."

Time Reference: Completed past action
Tense: Past Simple
Example: "I exercised yesterday."

Time Reference: Past experience (time unknown)
Tense: Present Perfect
Example: "I have exercised at that gym before."

Note: For more complex sentence structures like conditionals (e.g., "If I had time, I would exercise"), please refer to the chapter on Modality, conditionals and hypothesis.

Final Tip for Success

In your Paper 1 Writing, examiners look for a "variety of grammatical structures." Instead of only using the Present Simple, try to include at least one Present Perfect or Past Perfect sentence to show off your skills. Good luck!
