Where is the speaker standing?

Baseline · Vantage points

Six sentences about the same job. Match each to where the speaker is standing when they say it.

Standing now, looking at a finished period that is closed
Standing now, looking back at something still true
Standing at a past moment, looking further back
Standing at a future point, looking back
Standing now, looking back along something still running
Standing in the future, looking back along something still running

One story, three positions

The shop

My aunt has run the shop since 1998. She has never taken more than four days off at a time, and she has been saying she will sell it for at least a decade.

When my uncle died in 2016 she had already been running it alone for two years, because he had stopped coming in long before anybody said the word illness. By the time the will was read she had made every decision that mattered.

She turns seventy in September. By then she will have had the shop for twenty-seven years, and by the following March she will have been working seven days a week for thirty of them. She has agreed — twice, out loud, to me — that this is enough.

I do not believe her, and neither does she. But something has changed this year, and I notice that she has started giving things away.

Discovery Check

Four questions.

1. She has run the shop since 1998. Where is the speaker standing?

2. She had already been running it alone for two years. Standing where?

3. By then she will have had the shop for twenty-seven years. Standing where?

4. What is the same in all three of those sentences?

Focus on Form · 14 min

The three perfects, side by side

One system

Where you standFormExampleVantage words
Nowhave / has + participleShe has run it since 1998.since, for, already, yet, so far, up to now, ever, never
A point in the pasthad + participleShe had run it alone for two years.by then, by the time, before that, already
A point in the futurewill have + participleBy then she will have had it 27 years.by then, by June, by the time, before

And the continuous versions — still running up to that point

Where you standFormExample
Nowhave been + -ingShe has been saying it for a decade.
A past pointhad been + -ingShe had been running it alone since 2014.
A future pointwill have been + -ingBy March she will have been working seven days a week for thirty years.

One word does the anchoring in all three. By.

By now she has decided. By then she had decided. By March she will have decided. Same preposition, three positions, one instruction: stand here and look back.

If you can put by in front of a time and the sentence still makes sense, a perfect is probably the tense you want.

Which position

Five questions.

1. When I arrived, she ___ already.

2. I ___ three emails about it so far this morning.

3. By the time you read this, I ___.

4. She ___ here for six years when the company was sold.

5. Which sentence has no vantage point set at all, and is therefore a plain past?

Guided Practice · 16 min

Moving between the three

Open Cloze · Two to five words

Two to five words per gap. Read the vantage phrase in each sentence before you choose.

My aunt the shop since 1998. When my uncle died she it alone for two years. By the time the will was read she every decision that mattered. She turns seventy in September, and by then she it for twenty-seven years. By next March she seven days a week for three decades. She twice this year that it is enough.

Error Correction

Eight sentences. Seven contain an error; one is correct.

1. When I arrived she has already left.

2. By next June I am here for ten years.

3. I have seen him yesterday.

4. By the time we will get there, it will have closed.

5. She had been working there for six years when it closed. — correct as written

6. By then he will have been left.

7. I have been knowing her since school.

8. By 2016 she had ran it alone for two years.

Communicative Task · 10 min

One event, three positions

Task card · Speaking · Pairs · 5 minutes each

Choose one thing that has been going on in your life for a while — a job, a course, a place you live, a habit, a relationship with a city.

Five minutes. Tell it three times, from three positions, in this order.

  • From now: I have been… since / for… — what is still true, and what has changed so far.
  • From a past point: choose a moment — a day, an arrival, a decision — and say what had already happened by then.
  • From a future point: choose a date and say what you will have done, and what you will have been doing, by then.
  • Listener: after each of the three, say in one sentence where the speaker was standing. If you cannot, the vantage phrase was missing.

The listener’s sentence is the assessment. Not whether the tense was right — whether the position was clear. In practice the two turn out to be the same question, which is the argument this lesson is making.

Teacher note Where a listener cannot say where the speaker was standing, the missing element is almost never the auxiliary. It is the vantage phrase — no by then, no when I arrived, no so far. Feed one in and ask for the sentence again; the tense usually corrects itself without being mentioned.

Exit Check
