Past Continuous Tense

The past continuous tense describes actions that were in progress at a particular moment in the past. At the comprehensive level, you will practise combining it with the simple past to write engaging narratives and learn to avoid errors that commonly appear in examinations.

What You'll Learn

• How to combine the past continuous with the simple past to create vivid narratives
• How to use multiple background actions to set the scene in a story
• How to recognise and fix common errors involving the past continuous in longer passages
• How to choose the correct tense when a sentence contains both an ongoing action and a completed action

When to Use

1. Setting the scene in a story: "The rain was pouring down and the wind was howling through the trees as the children hurried inside."
2. An ongoing action interrupted by a sudden event: "The shopkeeper was arranging the fruits at his stall when a durian rolled off the shelf."
3. Two or more background actions happening together: "Passengers were boarding the MRT, office workers were rushing to their buildings, and hawkers were setting up their stalls."
4. Describing what was happening before a key event in a narrative: "Everyone was enjoying the outdoor concert when the sky suddenly turned dark."
5. Showing contrast between background and foreground actions: "While the rest of the class were completing their worksheets, Ahmad noticed something unusual outside the window."

How to Form

Narrative Pattern: Background + Event

Use the past continuous for the background action and the simple past for the main event.

Multiple Background Actions (Scene-Setting)

Use several past continuous clauses together, often joined by "and."

"As" -- Another Way to Introduce the Background Action

"As" works like "while" and introduces the ongoing action in past continuous.

Key Rules

1. The longer action takes the past continuous; the shorter action takes the simple past: In a narrative sentence with two actions, decide which was ongoing and which was sudden or completed. "She was crossing the road when a cyclist zoomed past." The crossing was the longer action; the cyclist zooming past was the sudden event.

2. Use "when" before the interrupting (simple past) action: "When" introduces the shorter action that breaks into the longer one. "I was revising for my spelling test when the lights went out."

3. Use "while" or "as" before the ongoing (past continuous) action: "While" and "as" signal the background action in progress. "While the teacher was collecting the papers, the students started chatting."

4. Multiple background actions all use the past continuous: When setting a scene, every ongoing action should be in the past continuous. "The wind was blowing, leaves were swirling, and thunder was rumbling in the distance." Do not mix simple past into the background unless that action is a completed event.

5. Do not use the past continuous for a series of completed actions: If actions happened one after another and each was finished before the next began, use the simple past for all of them. "She opened the door, picked up the parcel, and carried it inside." These are completed steps, not ongoing background actions.

6. Check was/were agreement, especially with tricky subjects: Even in long sentences, the subject determines whether to use "was" or "were." Watch out for subjects separated from the verb by a phrase: "The group of children was playing" (subject = group, singular). "The children in the group were playing" (subject = children, plural).

Common Mistakes

Clue Words

Words that introduce the background action (past continuous):

while, as, just as, all morning, all afternoon, the whole time, throughout the evening

Words that introduce the interrupting action (simple past):

when, suddenly, all of a sudden, just then, at that moment, without warning

Time markers used with the past continuous in narratives:

at that point, by then, at about 3 p.m., during the lesson, in the middle of the night

Tip: When writing a story, start a paragraph with the past continuous to paint the scene, then switch to the simple past for the main event. Think of it as the difference between a video playing in the background (past continuous) and a snapshot of the key moment (simple past).

Practice Tips

1. The "video and snapshot" test: Read the sentence and ask yourself -- is this action like a video still playing (ongoing), or like a snapshot of a finished moment (completed)? Use past continuous for the video and simple past for the snapshot.

2. Rewrite narratives: Take a short story written in the simple past and rewrite the opening paragraph using past continuous for the background actions. For example, change "The sun shone brightly. Birds sang in the trees." to "The sun was shining brightly. Birds were singing in the trees." Then add an interrupting event in the simple past: "Suddenly, a loud crash broke the silence."

3. Check every "when," "while," and "as" sentence: Split the sentence at the conjunction. Label each half as "ongoing" or "completed." Make sure the ongoing half uses past continuous and the completed half uses simple past.

4. Read your passage aloud: After writing a narrative, read it aloud. If you hear "was" or "were" followed by a base verb without -ing (e.g., "was cook" instead of "was cooking"), you have found an error. Similarly, check that you have not accidentally put a completed action into the past continuous.
