Question

When he entered my room i_(write) a letter

Answer 1

Answer:

When he entered my room I was writing a letter.

Explanation:

The given sentence is in the past tense and since the action, he entered is new so it is used in the simple past tense. But it also has another action that was going on for a longer time so we used the past continuous tense was writing here.

The given sentence uses both simple past and past continuous together here which denotes that a new action,i.e. he entered happened in between another longer action that was going on in the past,i.e. was writing a letter.
