Fix the phrase, not the verb

B1 Looking Back, Looking Forward
About this lesson ▾

Why tense errors here are really adverbial errors — and a consolidation of the word stress that has been quietly wrong since Unit 15.

Warm-up · 5 min

From the room, last lesson

Six sentences collected during the turns. In every one the auxiliary is the visible problem and the missing phrase is the real one.

Error Correction

Six sentences. Repair each — and notice what you had to add, not just change.

1. In five years I will work here for fifteen years.

2. Since 2019 I changed jobs twice.

3. When I arrived she has already gone.

4. This time next year I will live somewhere else.

5. I am here for six years.

6. By the time you will arrive we will have eaten.

The finding

Two questions, one answered

Every English tense answers two questions. The first is when did it happen. The second is when are you — where the speaker is standing when they look at it.

Learners answer the first question all the time, and answer it accurately. The second one they answer by default, and the default is always now, because Portuguese rarely requires the question to be asked at all. That is the entire difficulty, and it explains a set of errors that otherwise look unrelated: since 2019 I changed jobs, when I arrived she has gone, in five years I will work here for fifteen years.

It also explains why correcting the auxiliary rarely helps for long. A student who is told that had gone was needed learns that particular sentence. A student who notices that when I arrived had already moved them to 2016, and that everything after it has to be said from 2016, has learned all of them.

So the repair is not the verb. It is the phrase in front of it — and, more often, the phrase that was never there. Half the errors in the warm-up above were not wrong tenses. They were sentences with no position set at all, in which any tense would have sounded odd.

Set the position out loud. The tense follows almost by itself, and when it does not, you now have something to check it against.

Discovery Check

Three questions.

1. Which question do learners answer by default?

2. Why does correcting the auxiliary rarely transfer?

3. What was wrong with half the warm-up sentences?

The repair, and the stress

Set the position, then let the tense follow

PositionPhrases that set itTense that follows
Now, looking backsince, for, so far, up to now, already, yet, ever, neverpresent perfect · have done / have been doing
A past point, looking backwhen I arrived, by then, by the time, before thatpast perfect · had done / had been doing
A future point, looking backby then, by June, by the time, beforefuture perfect · will have done / will have been doing
Inside a future momentthis time next year, at eight, while you are therefuture continuous · will be doing
Now, looking forward at an eventno vantage phrase at allplain will

Two rules that are not negotiable.

1 · After when, by the time, before, as soon as and until, English uses the present for future time. By the time you arrive, never by the time you will arrive. That rule arrived in Unit 12 and it has not changed.

2 · A finished time word — yesterday, in 2019, ten years ago, last month — closes the period and refuses the present perfect. I have seen him yesterday.

Word to stress

Eight words from this unit. Match each to where the stress falls — say each one aloud as you place it.

re-FLEC-tion — before the -tion
pro-JEC-tion — before the -tion
pri-OR-i-ty — before the -ity
i-DEN-ti-ty — before the -ity
com-MIT-ment — the verb’s stress, unmoved
RE-a-lise — early, on the stem
GRAD-u-ate, with a full /eɪt/ at the end
GRAD-u-ate, with the ending reduced to /ət/
Repair check

Four questions.

1. A student says since 2019 I changed jobs twice. What is the most useful correction?

2. A sentence has no vantage phrase and no obvious position. What should you add first?

3. Where is the stress in possibility?

4. How do to separate and a separate room differ?

Guided Practice · 16 min

Phrase first, tense second

Which form

Ten sentences. Read the vantage phrase first, then choose. Five seconds each.

1. So far this year I ___ four books.

2. By the end of the year I ___ twelve.

3. When the train finally left, we ___ for two hours.

4. This time on Sunday I ___ on a beach.

5. I ___ him in 2019 and not since.

6. By the time she ___, we will have finished.

7. She ___ in that flat since her divorce.

8. By next March they ___ married for fifty years.

9. Don’t come at seven — we ___.

10. I ___ it before you get back, I promise.

Error Correction

Eight sentences. Seven need repair; one is correct. For each repair, say which phrase decided it.

1. I have finished it yesterday.

2. By 2030 I will be here for twenty years.

3. When she called, I have already left.

4. She has been living there since 2016. — correct as written

5. This time next month we will move house. — inside that time

6. By the time we will get there it will be dark.

7. Up to now nothing changed.

8. I am waiting for this letter since March.

Communicative Task · 10 min

The phrase relay

Task card · Speaking · Pairs · 10 minutes, fast

A says a vantage phrase. B has four seconds to produce a true sentence about their own life from that position.

Twenty exchanges in six minutes, then four minutes on stress.

  • Phrases to use: since 2019 · by then · when I left school · by next June · this time next year · so far this year · up to now · by the time I am forty · before I got here · at eight o’clock tomorrow.
  • Four seconds. If B hesitates, A says the position aloud — "you are standing in June, looking back" — and B tries again.
  • The sentence must be true. That is what makes the position real rather than an exercise.
  • Last four minutes: A says one of the abstract words from this unit; B says it with the stress marked, then puts it in a sentence.

Words for the stress round. reflection · projection · transition · priority · identity · possibility · commitment · achievement · development · realise · organise · prioritise · to graduate · a graduate · to separate · a separate room · specific · dramatic.

The last four are pairs. If the two members of a pair sound identical, one of them is wrong.

Teacher note The four-second limit matters. With ten seconds a student reconstructs the rule and gets it right, which teaches nothing they did not already know. Four seconds is short enough that only the phrase can do the work — which is the claim this lesson is making, tested in the mouth rather than argued on the page.

Exit Check

Two questions. Twenty seconds.
