Grammar
Past simple and past continuous
past simple
We use the past simple to talk about events in the past.
All persons are the same.
We make negative sentences in the past with didntaskt and the infinitive without to.
They didntaskt land on the runway.
We make questions in the past with Did and the infinitive without to.

in short answers we dontaskt repeat the main verb.
past continuous
We use the past continuous to describe an action in progress in the past.
We form the past continuous with subject + be + verb + -ing.
They were flying very low.
in questions, the order is be + subject + verb + -ing.
Were they standing on the rescue raft?
in short answers, we don’t repeat the verb + -ing:
Yes, they were. Yes, they were standing.
past simple vs past continuous
We often use the past simple and the past continuous in the same sentence.
We use the past simple for short actions. We use the past continuous for longer actions. The past simple describes an event that happens during a longer action in the past continuous.
We normally use when before the past simple clause and while before the past continuous clause.

While Flight 1549 was taking off from LaGuardia airport, it hit a flock of birds.
Pronunciation: past simple endings
The pronunciation of past simple regular verbs changes, depending on the spelling of the verb:
When the verb ends in an unvoiced sound, the -ed ending is pronounced [t]: look -> looked
When the verb ends in a voiced sound, the -ed ending is pronounced [d]: fail -> failed
When the verb ends in -t or -d, the -ed ending is pronounced [id]: land -> landed
