tense past , past perfect , past perfect continuous​

Answer 1

The blanks will be correctly filled as:

The fire had already destroyed much of the building when the firemen arrived.

When do we use the past perfect tense?

• We use the past perfect tense to describe an event which took place before another event in the past.
• In the statement above, the fire destroying the building and the firemen arriving are both actions in the past, hence the fire destroying the building will be in the past perfect tense.

When do we use past tense?

• We use past tense to describe an event that occurred in the past.
• As the firemen arrived in the past, hence past tense of the verb will be used here.
