B2 • About 32 minutes. Trace actors through a preparation log. Combine clauses only when their subjects and time relations allow it. Correct dangling or falsely simultaneous actions. Produce a concise, accurate event introduction with full clauses where needed.

Asha: list → unlock. Ben: paint board → place board. Leila: check captions → open display. Asha waits while visitors arrive: different actors require explicit subjects.

Meet the people and sequence

The following open-day log is fictional. Asha was the organiser, Ben was the caretaker, and Leila prepared the display. At eight, Asha checked the guest list at her desk. She finished the check before she unlocked the hall at eight fifteen. Ben had painted the welcome board the previous afternoon. The board was dry by the morning, and Ben placed it near the entrance. Leila carried a box of photographs into the hall and arranged them on a table. At eight thirty, Asha counted the chairs. She noticed that two were missing and asked Ben for help. Ben brought the extra chairs from the storeroom. While Asha waited at the entrance, the first visitors arrived. One visitor, Ravi, walked into the hall and found the lights too bright. He asked Ben to adjust them. Ben changed the setting, and the display became easier to see. After checking every caption, Leila opened the display area. Asha welcomed the visitors at nine. The hall had been built in 1980, but its entrance had been widened the previous year. No visitor painted a board, counted the chairs or unlocked the hall.

Actor map: Asha — checks the guest list, unlocks, counts, waits, welcomes. Ben — paints and places the board, brings chairs, adjusts lights. Leila — carries and arranges photographs, checks captions, opens the display. Ravi — enters, notices bright lights, asks Ben. The board receives paint; the hall was built. Keep these roles separate.

Use the editing test

Before combining two sentences, underline each subject. If the same person performs both actions, reduction may be possible. If the subjects differ, either name both in full clauses or rebuild the main clause without changing the facts. A past participle may describe an object that receives an action. A perfect participle marks earlier completion, but it still needs a logical subject.

The goal is a readable event introduction. Two clear participle clauses are enough for the final writing. Preserve finite clauses where they help the reader distinguish volunteers from visitors. Do not attach an opening phrase to the nearest convenient noun when that noun is not its actor or experiencer.

Subject tracing

Match each action to the person or thing identified in the log.

1 Who checked the guest list before unlocking?

Choose one answer.

Answer and explanation

Asha

The opening log assigns both checking and unlocking to Asha, in that order.

2 What received paint the previous afternoon?

Choose one answer.

Answer and explanation

the welcome board

Ben painted the welcome board. The board is the appropriate subject for a passive participle opening.

3 Who found the lights too bright?

Choose one answer.

Answer and explanation

Ravi

The log specifically identifies Ravi as the visitor who entered and found the lights bright.

4 Who checked every caption before opening the display?

Choose one answer.

Answer and explanation

Leila

Leila owns both the caption check and the display opening, so a shared-subject reduction is possible.

Choose the right form

Use active, passive or earlier-completion meaning as the evidence requires.

5 ___ the guest list, Asha unlocked the hall.

Choose one answer.

Answer and explanation

Having checked

Asha actively completed the check first. Having checked preserves both sequence and agency.

6 ___ the previous afternoon, the welcome board was dry by morning.

Choose one answer.

Answer and explanation

Painted

The board received Ben’s painting action; it did not paint anything.

7 ___ a box of photographs, Leila entered the hall.

Choose one answer.

Answer and explanation

Carrying

Leila is actively carrying the box while entering. The passive choices would make Leila the carried person.

8 ___ in 1980, the hall had a newly widened entrance.

Choose one answer.

Answer and explanation

Built

The hall was built by someone. Built gives a passive interpretation without inventing a named builder.

Safe sentence combining

Choose the version that preserves who did what and when.

9 Asha checked the guest list. Asha then unlocked the hall.

Choose one answer.

Answer and explanation

Having checked the guest list, Asha unlocked the hall.

Asha controls both actions. After Asha checked the guest list, she unlocked the hall is also a clear full-clause alternative.

10 Leila checked every caption. Leila then opened the display.

Choose one answer.

Answer and explanation

Having checked every caption, Leila opened the display.

The correct answer preserves the check-before-opening sequence. The alternative reverses it.

11 Ravi walked into the hall. Ravi found the lights too bright.

Choose one answer.

Answer and explanation

Walking into the hall, Ravi found the lights too bright.

Ravi is both the walker and the experiencer. The alternative version incorrectly lets lights control walking.

12 Asha waited at the entrance. The first visitors arrived during that time.

Choose one answer.

Answer and explanation

While Asha waited at the entrance, the first visitors arrived.

Keeping a full clause is best because the subjects differ. The reduced version transfers waiting to the visitors.

Fix the noticeboard draft

Repair agency and sequence. Clear full-clause versions are welcome.

13 Use the log to repair: “Carrying the photographs, the table was arranged by Leila.”

Choose one answer.

Answer and explanation

Leila carried the photographs and arranged them on the table.

The full clauses name Leila as the person carrying and arranging the photographs. This preserves the log instead of adding a new action.

14 Repair: “Having counted the chairs, two were missing.”

Choose one answer.

Answer and explanation

After Asha counted the chairs, she noticed that two were missing.

The full clause names Asha as the counter and preserves her observation without inventing a disappearance.

15 Repair: “Painted yesterday, Ben placed the board near the entrance.”

Choose one answer.

Answer and explanation

Ben placed the board, which he had painted the previous afternoon, near the entrance.

The board, not Ben, received paint. The relative clause makes that relationship explicit.

16 The log says captions were checked before the display opened. Which repair preserves it?

Choose one answer.

Answer and explanation

Having checked every caption, Leila opened the display.

Having checked marks the earlier completed action. Both sentences are grammatical, but only the correct answer is faithful to the log.

  1. Model answer and explanation

    Welcome to our open day. Asha organised the morning preparations. Having checked the guest list, she unlocked the hall at eight fifteen. Ben placed the welcome board near the entrance; he had painted it the previous afternoon. Leila carried in the photographs and arranged them on a table. Asha counted the chairs, and Ben brought two extra ones from the storeroom. While Asha waited at the entrance, the first visitors arrived. Ravi found the lights too bright, so Ben adjusted them. Having checked every caption, Leila opened the display area. Asha welcomed everyone at nine. The hall dates from 1980, and its entrance was widened last year.

Self-review and transfer

The model’s two participle clauses are Having checked the guest list and Having checked every caption. Their understood subjects are Asha and Leila respectively. Ben’s separate actions stay in finite clauses. Ask a partner to name the actor of every opening phrase without reading the log. Then check time, voice and source fidelity. If a full-clause repair is clearer than your reduced version, keep it. Do not count a shorter sentence as an improvement unless its meaning is equally recoverable.
