See it in action
Level A2Read or listen first. Don’t worry about the rules yet — just notice the verbs in bold.
The night the lights went out
Ben: What were you doing when the lights went out last night?
Ana: I was cooking dinner, and my flatmates were watching a film.
Ben: Was it raining at your place too?
Ana: Yes, it was pouring, and the wind was blowing really hard.
Ben: I was having a shower when it happened!
Quick check
How do we make the verbs in bold?
The past continuous is was or were + a verb with -ing: was cooking, were watching.
Quick check
Ana was cooking when the lights went out. When did she start cooking?
She was in the middle of cooking. The power cut happened during that action.
When to use it
Level A21. An action in progress at a time in the past
At nine o’clock yesterday, we were having breakfast.
2. A longer action interrupted by a shorter one
She was cooking dinner when the phone rang.
3. Two actions in progress at the same time
While I was studying, my brother was playing video games.
4. The background of a story
It was a cold evening. Snow was falling and people were hurrying home.
Quick check
“I was reading when you called.” Which action started first?
The reading was already in progress. Your call interrupted it.
Form: was / were + -ing
Level A1–A2| I / he / she / it | you / we / they | |
|---|---|---|
| Positive | she was working | they were working |
| Negative | she wasn’t working | they weren’t working |
| Question | Was she working? | Were they working? |
| Short answer | Yes, she was. / No, she wasn’t. | Yes, they were. / No, they weren’t. |
I was reading when you called.
What were you doing at eight last night?Wh- questions: question word + was / were + subject + -ing.
Short answers
Answer Was / Were…? with was / were — never did: Yes, I was. / No, they weren’t.
Were you sleeping? — No, I wasn’t.
Wrong: Was she working? — Yes, she did.Was she working? — Yes, she was.
Spelling of -ing
The -ing form follows the same spelling rules as the present continuous:
- Most verbs: add -ing — work → working, play → playing.
- Ending in -e: drop the e — make → making, write → writing.
- One vowel + one consonant (stressed): double it — run → running, stop → stopping.
- Ending in -ie: change to y — lie → lying, die → dying.
Quick check
My friends ___ watching TV when I arrived.
My friends = they, so use were. Use was with I, he, she and it.
when and while
Level B1when usually introduces the short action (past simple). while introduces an action in progress (past continuous).
I was walking home when it started to rain.
While I was walking home, it started to rain.
While Tom was cooking, his kids were doing their homework.Two actions in progress at the same time: both in the past continuous.
She was texting during the film.During + a noun (the film, the meeting, lunch).
Wrong: I was walking home during it started to rain.I was walking home when it started to rain.“During” goes before a noun: during the film.
Quick check
___ I was walking home, I met an old friend.
Use while before a subject and verb (while I was walking). During goes before a noun (during the walk).
Past continuous or past simple?
Level B1Use the past continuous for what was in progress; the past simple for completed actions, one after another.
When the phone rang, she was having a shower.She was already in the shower.
When the phone rang, she answered it.First the phone rang, then she answered.
Quick check
“When I arrived, they were having dinner.” Had they started dinner before I arrived?
Were having means dinner was already in progress. “When I arrived, they had dinner” means they started after I arrived.
State verbs
Level B1–B2State verbs describe a situation, not an action — know, want, need, understand, believe, remember, prefer, own, owe, agree, mean, deserve, depend on. They aren’t normally used in the continuous, even in the past, so use the past simple.
Wrong: I was knowing the answer.I knew the answer.
Wrong: She was wanting a new phone.She wanted a new phone.
Advanced uses
Level B2–C2Once the basics feel easy, these uses help you complain, make plans, ask politely and sound more natural.
Show the advanced uses
was always + -ing: annoying habits
was / were + always + -ing describes a habit that happened again and again — and annoyed the speaker. “Always” goes between was / were and the -ing verb.
When we lived together, he was always leaving his socks on the floor!
She left her keys at home. → She was always leaving her keys at home!Past simple = a plain fact. Was always + -ing = a complaint.
Quick check
“He was always leaving his socks on the floor!” How does the speaker feel about it?
Was always + -ing often shows that a repeated habit annoyed the speaker.
Plans seen from the past
For a fixed plan we say I’m flying to Rome tomorrow. When we look back at that plan from a moment in the past, it becomes was / were + -ing, often with that evening, the next day, the following week.
She couldn’t help us because she was flying to Rome the next day.
They couldn’t come because they were moving house the following week.
Quick check
“She couldn’t help because she was flying to Rome the next day.” Was she on the plane when she said it?
Here the past continuous is a plan seen from the past: the flight was the next day.
Polite requests: I was wondering if…
I was wondering / hoping / thinking… sounds softer and more polite than a direct request. The past form makes the request less direct, but it’s about now.
I was wondering if you could help me.Softer than “Can you help me?”.
We were hoping you could give us a lift.
I was thinking we could eat out tonight.A gentle suggestion.
Passive: was being done
Use was / were + being + past participle for an action that was in progress at a past moment, when who did it isn’t important. Negative: wasn’t / weren’t being + participle.
The road was being repaired when we arrived.The work was in progress — not finished.
The windows were being cleaned, so we couldn’t open them.
Luckily, the room wasn’t being used at the time.
Wrong: The bridge was been painted last week.The bridge was being painted last week.Being (in progress), not been.
Quick check
“The road was being repaired when we arrived.” Was the work finished?
Was being + participle shows the work was still in progress when we arrived. “The road was repaired” = the work was done.

- Form: was / were + -ing: she was working, they were working.
- A longer action in progress + a short action that interrupts it (past simple): I was reading when you called.
- while + an action in progress; when usually + the short action.
- State verbs (know, want, need…) stay in the past simple: I knew the answer.
