The five patterns

Collected across Lessons 1–5

PatternWhat appearsWhat it should beWhy it matters
Present perfect with a datehas been relocated on 14 Decemberwas relocated on 14 DecemberA stated past time forces the past simple
Past simple for a standing resultI revised the tablethe table has been revisedPT revisei covers both; English separates event from state
Missing locatorThe wall has been lowered.…and is shown on Sheet L5, Delta 2A change the reviewer cannot find is a repeat comment
Blanket hedge over a known factthe wall is approximately four feetthe wall is 3 ft 11 in at its highest pointReads as doubt about something you measured
Unhedged contradictionYour measurement is wrong.We would note that the wall scales to…Correct, and it costs you the reviewer
Teacher note Replace any row with what she actually produced in Lessons 1–5. As in Unit 7, the last two are not grammar errors and it is worth saying so out loud — they are the ones that cost her a round rather than a mark.

Focus on Form · 12 min

Restating a comment: reported speech that does not backshift

Two ways to report the comment

FormExampleUse when
No backshiftComment 2 states that the wall exceeds four feet.The comment still says it — you are quoting a live document
BackshiftThe reviewer said the wall exceeded four feet.You are reporting a past conversation, not the written comment
Reading, not quotingWe understand the comment to refer to the rear wall.The comment is ambiguous and you are fixing your reading of it
Requirement reportedComment 3 asks us to dimension the setbacks.The comment demands an action rather than states a fact

The no-backshift form is the one to default to in a letter, and it is the one Portuguese speakers under-use. The correction list is a document sitting on the reviewer’s desk; it has not stopped saying what it says. Backshifting it (the comment said the wall exceeded…) quietly puts it in the past, as though it were a remark someone once made — which is a strange thing to do to a document you are formally answering.

Keep the backshift for the phone call in the next lesson, where you really are reporting something someone said.

Fix them

Error Correction

Each sentence carries one of the five patterns. Rewrite it.

1. The rear wall has been lowered on 3 March 2025.

2. I revised the impervious surface table.

3. The turf has been itemised separately.

4. The rear wall is approximately four feet at its highest point.

5. Your measurement of the wall is wrong.

Teacher note Items 3, 4 and 5 are the ones to spend time on: nothing in them is ungrammatical and all three would pass any spell-and-grammar check. They fail professionally rather than linguistically — the same distinction Unit 7 drew, now in a document that goes to a named person who can say no again.
Word Formation · B2+

Complete each sentence with the correct form of the word in brackets.

  1. The set was returned with a list of from the Building Division. CORRECT
  2. We have no to dimensioning the setbacks as requested. OBJECT
  3. Comment 1 is and the table has been revised. ACKNOWLEDGE
  4. The response letter gives a full of each change. EXPLAIN
  5. The wall is with the published tables for segmental gravity walls. COMPLY
  6. The general notes state that the source drawing might be . ACCURATE

Communicative Task · 10 min

Rework your own three

Task card

The three responses you wrote in Lesson 5

Read them aloud and fix every instance of the five patterns.

  • Read aloud, not silently. A missing locator is much easier to hear than to see.
  • Every hedge covering something you measured comes out and is replaced by the figure.
  • Every hedge covering something you genuinely do not know stays — and gets more specific.

Feedback · 4 min

Grammar or nerve?

Of the changes you just made, how many were grammar and how many were confidence? Be honest about the split — they need different work, and only one of them is English.

Before the next lesson

Homework. Next lesson the reviewer telephones about your letter. Have the set open, know which sheet each of your three changes is on, and have the manufacturer tables for the wall to hand.
