Past Continuous Tense

The past continuous tense describes actions that were in progress at a particular moment in the past. At the mastery level, you will apply it confidently across PSLE-style questions -- combining it with other tenses, recognising tricky subjects, and avoiding the errors that commonly appear in examinations.

What You'll Learn

• How to use the past continuous tense accurately in all sentence types -- statements, negatives, and questions
• How to combine the past continuous with the simple past using "when," "while," and "as"
• How to handle subject-verb agreement challenges (collective nouns, indefinite pronouns, and "there was/were" constructions) in past continuous sentences
• How to distinguish between the past continuous and other tenses (simple past, present continuous, past perfect continuous) when multiple options appear in PSLE-style questions

When to Use

1. An action in progress at a specific past time: "At 7.30 a.m., the students were lining up at the assembly area."
2. A background action interrupted by a shorter action: "The reporter was interviewing the minister when the fire alarm went off."
3. Two or more simultaneous past actions: "While the chef was grilling the satay, his assistant was preparing the peanut sauce."
4. Setting the scene in narrative writing: "The wind was howling and dark clouds were gathering over the harbour."
5. Polite or tentative past inquiries: "I was wondering if you could lend me your reference book."

Key Rules

1. Subject-verb agreement with "was" and "were": Use was with I, he, she, it, and singular noun subjects. Use were with you, we, they, and plural noun subjects. This rule applies even when the subject is far from the verb: "The boy sitting among the older contestants was trembling with excitement."

2. Collective nouns take "was" when acting as a unit: "The committee was discussing the proposal." If the members are acting individually, use "were": "The team were arguing among themselves." In PSLE, the default is to treat collective nouns as singular unless the sentence clearly emphasises individual action.

3. "There was" vs "there were": The verb agrees with the noun that follows. "There was a dog barking in the yard." "There were several children playing by the fountain."

4. "When" introduces the interrupting action (simple past); "while" and "as" introduce the ongoing action (past continuous): "She was crossing the road when a car sped past." "While she was crossing the road, a car sped past."

5. Stative verbs are generally not used in the continuous form: Verbs that describe states rather than actions -- such as know, believe, belong, contain, own, prefer, understand -- normally stay in the simple past. "She knew the answer" (not "She was knowing the answer").

6. Spelling rules for adding -ing: Drop the silent -e (make -> making), double the final consonant after a short stressed vowel (run -> running, begin -> beginning), change -ie to -y (lie -> lying, die -> dying). These spelling patterns are frequently tested.

7. Past continuous vs past perfect continuous: The past continuous describes an action in progress at a past moment. The past perfect continuous (had been + verb-ing) describes an action that had been going on before another past action. "She was reading when I arrived" vs "She had been reading for two hours when I arrived."

Common Mistakes

Clue Words

Time markers that signal past continuous

at that moment, at 6 p.m. yesterday, all morning, all afternoon, the whole day, throughout the evening, at that point in time

Conjunctions that pair with past continuous

while, when, as, just as

Sentence starters that set the scene

It was raining..., The sun was setting..., People were rushing...

Words that signal simple past (the interrupting action)

suddenly, just then, all of a sudden, at once

Tip: In a "when" / "while" sentence, identify the longer action and the shorter action. The longer action takes the past continuous; the shorter action takes the simple past. "While I was walking home, it suddenly started to rain."

Practice Tips

1. Two-clause analysis: When you see a sentence with "when" or "while," split it into two clauses. Decide which action was ongoing (past continuous) and which was completed or sudden (simple past). This technique works for most PSLE cloze and editing questions.

2. Subject identification drill: Before selecting "was" or "were," underline the true subject and cross out any prepositional phrases between the subject and the verb. "The group of tourists (was/were) taking photographs" -- the subject is "group" (singular), so the answer is was.

3. Stative verb checklist: Memorise the common stative verbs -- know, believe, belong, contain, own, prefer, understand, want, need, like, love, hate, mean, remember, realise. If the verb is on this list, avoid putting it in the continuous form unless it has an action meaning (e.g., "I was thinking about it" is acceptable because "think" can describe a process).

4. Spelling self-check: After writing a past continuous sentence, check the -ing form. Ask: Does the base verb end in silent -e? (Drop it.) Does it end in a single consonant after a short stressed vowel? (Double it.) Does it end in -ie? (Change to -y.) These three checks catch most spelling errors.
